Report to Parliament on the making of a pandemic declaration - Report under section 165AG of the Public Health and Wellbeing Act 2008
Purpose of the report
           This report is provided to Parliament pursuant to section 165AG of the Public Health and
           Wellbeing Act 2008 (PHW Act) following the making of a pandemic declaration by the Premier
           under section 165AB of the PHW Act, commencing from 11:59pm on 15 December 2021, in
           relation to the Novel Coronavirus 2019 (SARS-CoV-2), the virus which causes the coronavirus
           disease (COVID-19).

           As required under section 165AG of the PHW Act, this report contains a statement of reasons
           for the making of a pandemic declaration and a copy of the advice of the Minister for Health,
           Martin Foley MP, and the Chief Health Officer, Adjunct Clinical Professor Brett Sutton MBBS
           MPHTM FAFPHM FRSPH FACTM MFTM, in respect of the making of the pandemic
           declaration.

           The making of a pandemic declaration for the State of Victoria has been informed by
           consultation with, and advice received from, both the Minister for Health and the Chief Health
           Officer.

OFFICIAL
Report to Parliament on the making of a pandemic declaration - Report under section 165AG of the Public Health and Wellbeing Act 2008
Provisions under the Public Health and Wellbeing Act
           2008
           Under section 165AB of the PHW Act, the Premier may make a pandemic declaration if the
           Premier is satisfied on reasonable grounds that there is a serious risk to public health arising
           from a pandemic disease or a disease of pandemic potential. The Premier must consult with,
           and consider the advice of, the Minister for Health and the Chief Health Officer before making a
           pandemic declaration.

           Under section 165AC of the PHW Act, the period for which an initial pandemic declaration
           continues in force cannot exceed four weeks. Under section 165AE of the PHW Act, the
           Premier may extend a declaration if satisfied that there continues to be a serious risk to public
           health arising from the pandemic disease or disease of pandemic potential. There is no limit on
           the number of times a pandemic declaration may be extended, but the period of each extension
           must not be longer than 3 months.

           Under section 165CH of the PHW Act, if a pandemic declaration is made in respect of the same
           infectious disease as the subject of an existing State of Emergency declaration, the declaration
           of the State of Emergency ceases to be in force in respect of so much of each emergency area
           that is, or is within, a pandemic management area.

           Making of a pandemic declaration by the Premier
           Based on the advice of, and in consultation with, the Minister for Health and the
           Chief Health Officer, in response to the serious risk to public health presented by COVID-19,
           the Premier made a pandemic declaration on 10 December 2021.

           The declaration:

              •   Commences from 11:59pm, on 15 December 2021, until 11:59pm on 12 January 2022.
              •   Is made in respect of the coronavirus disease of 2019 (COVID-19), caused by the virus
                  identified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
              •   Is in force throughout the State of Victoria.

           The signed declaration is at Attachment A. A copy of the advice of the Chief Health Officer
           supporting the making of this declaration is at Attachment B, dated 8 December 2021. A copy
           of the advice of the Minister for Health supporting the making of this declaration is at
           Attachment C dated 8 December 2021.

           Statement of reasons for the pandemic declaration
           In deciding to make a pandemic declaration, the Premier has consulted with, and considered
           the advice of, both the Minister for Health and the Chief Health Officer.

           As required by 165AG(1)(a) of the PHW Act, a statement of reasons for the making of the
           pandemic declaration must be provided. This aims to promote additional transparency and
           accountability of government and provide a clear explanation for the decision to allow powers to
           be exercised under Part 8A of the PHW Act.

OFFICIAL
Report to Parliament on the making of a pandemic declaration - Report under section 165AG of the Public Health and Wellbeing Act 2008
A pandemic declaration is required to authorise the use of powers to manage pandemics
           through the making and enforcement of pandemic orders and the use of pandemic
           management powers across Victoria. This will remain necessary while there remains a serious
           risk to public health arising from COVID-19.

           After consulting with and considering the advice of both the Minister for Health and the Chief
           Health Officer, the Premier was satisfied that there is a serious risk to public health arising from
           the pandemic disease, COVID-19. In reaching this conclusion the Premier notes that “serious
           risk to public health” is defined in section 3 of the PHW Act as “a material risk that substantial
           injury or prejudice to the health of human beings has occurred or may occur, having regard to:

               •   the number of persons likely to be affected
               •   the location, immediacy, and seriousness of the threat to the health of persons
               •   the nature, scale and effects of the harm, illness or injury that may develop
               •   the availability and effectiveness of any precaution, safeguard, treatment, or other
                   measure to eliminate or reduce the risk to the health of human beings.”

           In making this decision, the Premier took into account the matters set out below.

           COVID-19 is a pandemic disease
           Based on the advice of the Minister for Health and Chief Health Officer, the Premier was
           satisfied that COVID-19 is a pandemic disease.

           Section 3(5) of the PHW Act provides that “an infectious disease is a pandemic disease at a
           particular time if, at that time, there is a pandemic outbreak of that infectious disease”. An
           “infectious disease” is defined in section 3(1), and includes a human illness or condition due to
           a specific infectious agent or its toxic products that arises through transmission of that agent or
           its products from an infected person, to a susceptible person, either directly or indirectly through
           an intermediate plant or animal host, vector or the inanimate environment.

           SARS-CoV-2 is the virus that causes COVID-19. The virus first appeared in Wuhan, China, in
           December 2019. The World Health Organisation (WHO) declared the outbreak a Public Health
           Emergency of International Concern on 30 January 2020 and a pandemic on 11 March 2020.
           The WHO has yet to declare an end to the global pandemic.

           SARS-CoV-2 is a highly transmissible virus, primarily transmitted from person to person
           through respiratory droplets and aerosols carrying infectious viral particles that are inhaled or
           come into contact with susceptible hosts. While the disease can also be transmitted by direct
           contact and fomite, the risk of transmission via these methods is lower. 1

           Since tracking commenced on 30 December 2020, the WHO Coronavirus dashboard had
           recorded 265,713,467 cases with 5,260,888 deaths as of 7 December 2021. 2

OFFICIAL
Transmission of the disease across continents is sufficiently widespread to constitute a
           pandemic, noting that according to the WHO Coronavirus data table, only seven countries
           worldwide have not officially recorded a case of COVID-19 since the pandemic began. 3

           The virus can mutate into more transmissible, virulent and difficult to control variants. An
           example of this is the Delta variant of concern (B.1.617.2). The Delta variant of concern was
           first detected in India in October 2020. 4 Evidence suggests that this variant has increased
           transmissibility and virulence, compared to both other variants and the ancestral Wuhan strain
           of the virus. 5 A further variant of concern – designated as Omicron by the WHO on 26
           November 2021 – was first detected in southern African countries in November 2021. 6

           A serious risk to public health arises from COVID-19
           Based on the advice of the Chief Health Officer and Minister for Health, the Premier was
           satisfied that COVID-19 gave rise to a “serious risk to public health”. In particular, he was
           satisfied that COVID-19 gave rise to a “material risk that substantial injury or prejudice to the
           health of human beings has occurred and may occur”, having regard to:

               •   the number of persons likely to be affected
               •   the location, immediacy, and seriousness of the threat to the health of persons
               •   the nature, scale and effects of the harm, illness or injury that may develop
               •   the availability and effectiveness of any precaution, safeguard, treatment, or other
                   measure to eliminate or reduce the risk to the health of human beings.

           The number of persons likely to be affected

           Based on the advice of the Chief Health Officer and Minister for Health, the Premier was
           satisfied that the Victorian population is potentially vulnerable to infection with COVID-19, with
           poor health outcomes reported across all age groups, particularly for people with a wide range
           of common pre-existing conditions. 7 Additionally, international experience demonstrates that
           uncontained outbreaks of the disease can overwhelm hospital systems to the point of making
           healthcare inaccessible to those seeking treatment for reasons unrelated to COVID-19. This
           means that the number of people likely to be affected includes, primarily, those who are at risk
           of being infected with COVID-19, but also those who are affected by being unable to receive
           the care they need for other reasons, should the outbreak overwhelm health system capacity 8.

OFFICIAL
SARS-CoV-2 is a novel infectious agent to which the global population had not been
           exposed prior to late 2019 (and hence had not acquired resistance), meaning that there was
           and continues to be significant immunological susceptibility for widespread transmission. 9

           SARS-CoV-2 is highly transmissible and can spread easily from person to person through
           multiple modes of transmission. 10

           SARS-CoV-2, like any virus, has the capacity to mutate into more transmissible and virulent
           strains. 11

           Infection with SARS-CoV-2 can cause significant disease and death. 12

           There have so far been 130,029 confirmed cases in Victoria out of an Australian total of
           219,118, 13 and these numbers would have been significantly higher if not for the pandemic
           management measures maintained throughout the pandemic so far. This is evidenced by the
           case and death rates in other comparable countries. 14

           COVID-19 poses a significant risk to public health because a high rate of hospitalisations from
           unconstrained transmission of COVID-19 would have the effect of denying treatment to people
           with other conditions requiring medical care, as has occurred in other countries where hospital
           systems have been overwhelmed. In weighing the number of people likely to be affected,
           consideration was given not only to the number of people likely to contract COVID-19, but to
           the fact that the pandemic creates a material risk of prejudicing the health of Victorians who do
           not have COVID-19 but who require medical care for other reasons and may be denied this
           care if the healthcare system is significantly burdened. 15

           In considering the number of people likely to be affected by the risk, the Premier has
           considered whether high vaccination rates are likely to have diminished the seriousness of the
           risk in the current settings. While the considerable protection offered by high vaccination rates
           amounts to a significant change in the risk profile, the scale of the COVID-19 pandemic
           continues to leave a significant number of people exposed to risk. 16

           The location, immediacy, and seriousness of the threat to the health of persons

           Based on the advice of the Chief Health Officer and Minister for Health, the Premier was
           satisfied that the threat to persons likely to be affected is immediate and serious. The Premier
           was also satisfied that the threat existed to persons throughout Victoria, with people in regional
           areas of Victoria rendered particularly vulnerable.

           COVID-19 is circulating in the Victorian community and accordingly the threat is immediate. As
           of 7 December 2021, the seven-day case average is 1192 and there are 297 cases in
           hospital. 17 Since November 2020, the proportion of returned positive tests has been between
           1.5 and 2 per cent – a higher rate compared to New South Wales – which indicates there is

likely to be a significant number of additional cases in the community which are not being
           identified. 18

           When considering the location of the threat, consideration has been given to the capacities of
           regional Victoria’s COVID-19 response where healthcare resources are limited compared to
           metropolitan areas. Uncontained outbreaks in regional Victoria could therefore create very
           serious threats to health more easily than in metropolitan areas. 19

           While acknowledging that hospitalisations for COVID-19 have declined from their peak, the
           threat posed by COVID-19 transmission to Victorians and Victoria’s healthcare system is, in the
           view of the Chief Health Officer, “serious and ongoing”. 20 Although Victoria has increased its
           hospital capacity to respond to the pandemic, there is a finite ceiling to which hospital bed
           capacity can be increased, and hospital care is only a partial defence against the risk of serious
           illness or death. 21 The Chief Health Officer advised that the available therapeutic interventions
           for COVID-19, including antivirals, steroids and supportive care, are only partially effective in
           reducing mortality and decreasing hospital stays. 22

           The nature, scale and effects of the harm, illness or injury that may develop

           Based on the advice of the Chief Health Officer and Minister for Health, the Premier was
           satisfied that the nature, scale and effects of the harm posed by COVID-19 across Victoria are
           sufficiently grave and significant to merit a designation as a serious public health risk.

           COVID-19 displays a spectrum of clinical outcomes, from asymptomatic or mild illness to
           serious illness and, in some cases, death. 23 While children tend to display a milder or even
           asymptomatic infection, the virus can nonetheless cause severe illness requiring intensive care
           treatment among children. 24

           As of 10 October 2021, 25 more than 1 in 10 people in Australia across all age groups who
           contracted COVID-19 so far this year have been hospitalised. However, the hospitalisation rate
           was even higher than this among adults in most age groups, 26 even if they were not elderly.
           The table overleaf was provided as part of the Chief Health Officer’s advice on 8 December.

OFFICIAL
Vulnerable members of society, including the elderly, those with co-existing medical conditions,
           and those in lower socioeconomic groups, have been shown to be disproportionately impacted
           and remain at risk. 27

           It is not possible to predict with confidence who will have an asymptomatic infection or mild
           illness and who will have a more severe illness and poorer outcome, with serious illness
           recorded among people across all age groups. 28

           Estimates from published literature and epidemiological sources indicate the case fatality rate
           for COVID-19 varies. The current estimate of case fatality rates in Victoria is 0.15 per cent for
           individuals under 70 and 14.8 per cent for individuals aged over 70. 29

           It is important to emphasise that the above figures were collected in an environment of public
           health measures that suppressed outbreaks to protect vulnerable people and constrained the

possibility of even more lethal outcomes. 30 Without pandemic management measures, the
           likely rate of death and hospitalisations in Australia would have been worse. 31

           The high transmissibility and risk of death posed by COVID-19 distinguishes it from other
           illnesses which commonly circulate in the community and warrant a more stringent response.
           By way of comparison, the highest annual number of deaths from confirmed influenza in
           Australia in recent years occurred in 2017, which caused 277 deaths in Victoria and 1,255
           deaths Australia-wide. 32 Modelling indicates that without public health measures, unrestrained
           outbreak of COVID-19 would likely have caused tens of thousands of deaths in Australia over
           the course of the pandemic. 33

           Long-term impacts of COVID-19 are still being ascertained, with evidence that some people
           report persistent symptoms following recovery from the disease. These long-term symptoms
           can impact multiple organ systems and cause mild to severe illness. 34

           The availability and effectiveness of any precaution, safeguard, treatment, or other
           measure to eliminate or reduce the risk to the health of human beings

           Based on the advice of the Chief Health Officer and Minister for Health, the Premier considered
           the availability and effectiveness of precautions, safeguards, treatments, and other measures to
           eliminate or reduce the risk to the health of human beings.

           The Premier was satisfied that current vaccination rates alone will not suffice to contain
           transmission within health system capacity, and available treatments are only partially effective
           in mitigating serious illness or death. 35

           Vaccination is a crucial tool to manage the risk posed by COVID-19 and is the most important
           pandemic management tool available. 36 While vaccinated people may still contract the virus,
           the risk of developing a severe illness – if any symptoms at all – is significantly reduced. 37
           Available vaccines have a powerful effect on minimising the risk of serious illness or death. 38
           Reported vaccine effectiveness against death from Delta variant infection was 91 per cent for
           AstraZeneca and 90 per cent for Pfizer across all age groups. 39 Furthermore, vaccines offer
           protection against the risk of ‘long COVID’. 40 They also lower the risk that an infected person
           will transmit the virus to others. 41 Vaccination thus serves a dual purpose in combatting the
           pandemic: it protects individuals from the harm of severe disease and death, and protects the
           community by slowing the spread of the virus to others. 42

However, vaccination alone will not suffice to contain transmission within health system
           capacity, and some additional public health measures are needed for an effective response to
           the serious health risk posed by COVID-19. 43

           Vaccines alone are insufficient because:

           •    Access to vaccines is not currently available to children under the age of 12 years in
                Australia (although the first shipment of childrens’ doses is due to arrive in Australia in
                January 2022), as well as other people who for medical reasons cannot be vaccinated. 44
           •    Despite the current high levels of vaccination coverage in Victoria, many people in the
                population will remain susceptible to this highly transmissible infection, and observational
                studies indicate vaccine efficacy may wane after a period of approximately 6 months
                following vaccination. 45
           •    The risk of immunity waning in the months following vaccination is an area of ongoing
                research. 46 Evidence suggests that vaccine efficacy may wane after a period of
                approximately six months following vaccination. 47
           •    There is a risk that strains of the SARS‑CoV‑2 virus will emerge against which vaccines
                are less effective and the use of public health measures will allow us to monitor for, and
                mitigate against, this possibility. 48

           There are limited preventative and therapeutic interventions to manage COVID-19 and – other
           than vaccines – many interventions remain supportive (oxygen, ventilation etc.) rather than
           curative or preventive. The available therapeutic interventions of antivirals, steroids and
           supportive care, have been shown to be only partially effective in reducing mortality and
           decreasing hospital stays. 49

           Other countries with high vaccination rates have nonetheless endured increased hospitalisation
           rates following relaxation of restrictions, even during the northern summer and among countries
           with warm climates. 50 Resurgent outbreaks among highly vaccinated populations are driven by
           those who remain unvaccinated, as well as the elderly and vulnerable individuals with co-
           morbidities who suffer breakthrough cases and asymptomatic healthy individuals who transmit
           the virus. 51 Portugal, Singapore, Chile, Denmark and Ireland have all achieved vaccination
           levels above 90 per cent, but have needed to reimpose various health measures, including
           mandatory face masks in public settings, limits on gatherings and venue caps, to curtail a
           worrying resurgence of hospitalisations and intensive care admissions following the easing of
           restrictions. The advice from the Chief Health Officer is that this demonstrates that high
           vaccination rates and warm weather will not be sufficient to defend against a resurgence of
           COVID-19 in the Victorian summer, and ongoing public health interventions will be needed. 52

OFFICIAL
Efforts to keep the COVID-19 outbreak within the constraints of the healthcare system will be
           most effective if vaccination is complemented by other public health measures such as testing,
           contact tracing, isolation of positive cases and quarantine. 53 Proportionate control measures
           such as international travel permits, testing requirements and exclusion from sensitive settings
           during the period of highest risk will also ensure the serious threat to public health posed by
           COVID-19 is managed in a way that protects vulnerable people and mitigates the risk of
           uncontrolled transmission. 54

           Guiding principles informing the decision to make a pandemic declaration

           In determining that COVID-19 is a pandemic disease that gives rise to a serious risk to public
           health, the Premier had regard to the following guiding principles outlined at sections 5 – 10 of
           the PHW Act.

           Evidence-based decision-making

           In making the pandemic declaration the Premier had regard to the principle of evidence-based
           decision-making (as required under section 5 of the PHW Act).

           The advice of the Chief Health Officer was that evidence supports the view that the most
           effective and efficient response to the COVID-19 pandemic requires ongoing use of public
           health and social measures, rather than relying on vaccine immunity and disease treatment
           alone. 55 The Minister for Health likewise advised that powers under the PHW Act were
           necessary for the pandemic to be managed effectively. 56 The Premier’s decision to make a
           pandemic declaration therefore advances the principle of evidence-based decision-making by
           empowering the Minister for Health to use measures under Part 8A of the PHW Act to manage
           the COVID-19 pandemic using public health and social measures as a complement to
           vaccination and disease treatment, in line with available evidence about the most effective
           measures to protect public health and wellbeing.

           Precautionary principle

           As outlined above, based on the advice of the Chief Health Officer 57 and Minister for Health, 58
           the Premier was satisfied that the COVID-19 pandemic poses a serious risk to public health.
           The Chief Health Officer noted that understanding of the nature of the SARS-CoV-2 virus
           continues to evolve. 59 Consideration has been given this uncertainty but consistent with the
           precautionary principle at section 6 of the PHW Act, a lack of full scientific certainty should not
           be used as a reason to prevent or control the public health risk, given the COVID-19 pandemic
           constitutes a serious threat to public health and wellbeing.

Principle of primacy of prevention

           The Premier had regard to the principle of primacy of prevention set out in section 7 of the
           PHW Act. The Premier received advice from the Minister for Health that the enlivening of
           powers under Part 8A of the PHW Act was necessary for him to eliminate or reduce the serious
           risk to public health arising from COVID-19 60 and that the response to COVID-19 would be less
           effective without these powers. 61

           The advice of the Minister for Health was supported by the advice of the Chief Health Officer,
           who was guided by the overarching principle of prevention of disease, illness, injury, disability
           or premature death, consistent with the objectives of the Act. 62 In considering the totality of
           evidence in pursuit of this aim, the Chief Health Officer concluded that his advice to the Premier
           was to make a pandemic declaration in order to make available the relevant powers necessary
           to increase the prospects of limiting the transmission of COVID-19 in Victoria and continue to
           minimise, as much as possible, the serious risk to public health. 63

           Principle of accountability

           The Premier had regard to the principle of accountability in section 8 of the PHW Act. He had
           regard to the requirement to table this report under section 165AG including a statement of
           reasons for making the pandemic declaration and a copy of the advice of both the Minister for
           Health and the Chief Health Officer with respect to the making of the pandemic declaration. The
           Premier was satisfied that tabling these documents in Parliament ensures his decision is
           transparent, systematic and appropriate and provides members of the public access to reliable
           information to facilitate a good understanding of the relevant public health issues and the
           opportunity to participate in policy and program development.

           Principle of proportionality

           As outlined in this report, based on the advice of the Chief Health Officer 64 and Minister for
           Health, the Premier was satisfied that COVID-19 pandemic poses a serious risk to public
           health. 65 He had regard to the principle of proportionality in section 9 of the PHW Act, and was
           satisfied that his decision to declare a pandemic was a proportionate response to prevent,
           minimise and control the public health risk that COVID-19 presents. Based on the advice of the
           Chief Health Officer 66 and Minister for Health, 67 the Premier was satisfied that making a
           pandemic declaration was not arbitrary.

The Premier had regard to the principle of collaboration in section 10 of the PHW Act.

           The Premier has collaborated at a national level through the National Cabinet in informing the
           most appropriate Victorian response to the COVID-19 pandemic and furthering understanding
           of the consequences of the COVID-19 pandemic

           The advice of the Chief Health Officer has similarly been informed by collaboration with the
           Australian Health Protection Principal Committee. 68

           Charter of Human Rights and Responsibilities

           A pandemic declaration does not itself directly affect the human rights of any person (either
           positively or negatively).

           Although the making of a pandemic declaration does not itself directly affect the human rights
           of any person, it is the necessary first step in enlivening certain other powers under the PHW
           Act. Those powers include:

                a.     the power of the Minister for Health to make a pandemic order (section 165AI);
                b.     the power of authorised officers to exercise pandemic management order powers
                       (section 165B);
                c.     the power of authorised officers to exercise pandemic management general powers
                       (section 165BA);
                d.     the power of authorised officers to exercise public health risk powers (section 190).

           These powers form part of a framework that is designed to protect public health and wellbeing
           in Victoria in the context of pandemics (section 165A(1)).

           Noting that the most immediate potential consequence of the making of a pandemic declaration
           is that the Minister for Health will be empowered to make pandemic orders, the Premier
           recognised that the future exercise of that power may affect and limit human rights. The powers
           of authorised officers may also have that effect, but that can only occur if the Chief Health
           Officer authorises authorised officers to exercise those powers. A further step is therefore
           necessary for that to occur. Further, the Minister’s power is also the power that potentially has
           the most far-reaching consequences for human rights, because a pandemic order may to apply
           to “all persons” (section 165AK(1)(a)). In contrast, the powers of authorised officers are more
           limited (see for example section 165BA(4)).

           The Premier gave consideration to how the Minister’s power to make pandemic orders might be
           exercised, having regard to the examples in section 165AI(2), and how that exercise may affect
           and limit the following human rights: equality (section 8); protection from medical treatment
           without full, free and informed consent (section 10 (c)); freedom of movement (section 12);
           rights to privacy, family and home (section 13(a)); freedom of thought, conscience, religion and
           belief (section 14); freedom of expression (section 15); peaceful assembly and freedom of
           association (section 16); protection of families and children (section 17); cultural rights (section
           19); property rights (section 20); right to liberty and security of person (section 21); right to
           humane treatment when deprived of liberty (section 22 (1)); self-incrimination (section 25(2)(k)).

OFFICIAL
However, the Premier recognised that, ultimately, whether any exercise of the Minister’s power
           will affect and limit human rights — and, if so, how — will ultimately depend on how the powers
           are exercised by the Minister and the circumstances in which they are exercised.

           The Premier recognised that the Minister for Health is a public authority. The PHW Act
           recognises that a public authority must give proper consideration of human rights protected by
           the Charter when making decisions, and must act compatibly with human rights (section
           165A(2)(c)). Following the making of a pandemic order, the Minister must ensure that a
           document, which addresses whether the order limits human rights, and if so, addresses the
           matters set out in section 7(2) of the Charter, is published online (section 165AP(2)(c)-(d)).

           The Premier also recognised that the Minister’s power to make a pandemic order is expressly
           limited by a “reasonably necessary” criterion, which itself requires a “proportionality”
           assessment to be undertaken by the Minister.

           Ultimately, the Premier recognised that whether the requirements of the Charter are satisfied in
           relation to any individual exercise of the Minister’s power will depend on how the power is
           exercised and the circumstances in which the power is exercised.

           Conclusion to the statement of reasons

           Having considered the advice of the Minister for Health and the Chief Health Officer, the
           Premier was satisfied on reasonable grounds that COVID-19 is a pandemic disease that gives
           rise to serious risk to public health throughout Victoria.

           In reaching this conclusion, the Premier considered that COVID-19 is highly transmissible;
           causes serious illness and death; and unconstrained outbreaks of this disease across the world
           have outpaced hospital capacities to a scale not witnessed in modern memory. An outbreak
           beyond the limits of Victoria’s healthcare system would be catastrophic, and imperil the health
           of all Victorians who require medical care, whether for COVID-19 or for other reasons.

           The Premier considered the safeguards and treatments available and concluded that while
           vaccination remains the state’s best defence against COVID-19, it does not supplant the need
           for other public health measures. The most effective response to the pandemic requires
           vaccines to be complemented by other measures protecting human health, particularly the
           health of the most vulnerable.

Introduction and Summary
1.   In response to the request from the Premier of Victoria on 7 December 2021, set out below
     is my advice as Victoria’s Chief Health Officer, regarding whether the Victorian Premier
     should make a pandemic declaration under section 165AB of the Public Health and
     Wellbeing Act 2008 (Vic) (the Act) in relation to the coronavirus disease (COVID-19).

2.   I advise that there is a serious risk to public health throughout the State of Victoria arising
     from a pandemic disease, namely COVID-19. On this basis, I advise the Premier to make a
     pandemic declaration.

3.   In providing this advice, I am aware of the legislative context in which the Premier’s request
     is made. If the Premier makes a pandemic declaration, the Act empowers Victoria’s Minister
     for Health to deploy a focused public health response, which may include a combination of
     non-pharmaceutical and pharmaceutical interventions. The Act requires that the public
     health response be proportionate to the public health risk that the disease (in this case,
     COVID-19) poses.

4.   I explain my reasons for this advice below, but in summary I consider that, at the time of this
     advice, COVID-19 is and remains a serious risk to public health, despite high vaccination
     rates in the Victorian population due to the following:

         a) Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus which
             causes COVID-19, is a novel infectious agent to which the global population had not
             previously been exposed, meaning there was no pre-existing immunity and hence
             significant immunological susceptibility to infection.

         b) SARS-CoV-2 is highly transmissible and can spread easily from person to person
             through multiple modes of transmission, and primarily through the airborne route.

         c) There is currently widespread community transmission of SARS-CoV-2 across
             Victoria.

         d) There continues to be a high number of cases reported daily relative to other
             Australian jurisdictions, including a significant proportion who require supported
             care at home, primary care interventions, hospitalisation, intensive care unit (ICU)
             admission, ventilatory support and Extracorporeal Membrane Oxygenation (ECMO)
             – sometimes for several weeks - with a consequent significant burden on Victoria’s
             health services.
         e) The recent easing of restrictions for vaccinated international arrivals may result in
             incursions of new variants of concern (VOC) which may pose a greater public health
             risk to Victoria.

                                                   2
                                       OFFICIAL: Sensitive
f)   There is an ongoing risk that SARS‑CoV‑2 will mutate into more transmissible,
                immune evading and/or more virulent strains (World Health Organisation(a)
                2021) that may result in greater morbidity and mortality, which may require a
                strengthened public health response. This has been evidenced by multiple VOC,
                including the Delta and Omicron variants, which have emerged since the World
                Health Organisation (WHO) declared a pandemic. WHO declared the B.1.1.529
                variant, now named Omicron, as a VOC on 26 November 2021. Preliminary
                evidence suggests that Omicron has a large number of concerning mutations and
                that there may be an increased risk of reinfection and immune escape, including to
                current vaccines, with the Omicron variant compared with the ancestral COVID-19
                strain and other VOCs (WHO(b) 2021).

           g) Although vaccines are proven to be effective, they do not guarantee protection to all
                individuals. Additionally, vaccine effectiveness appears to wane over time, which
                necessitates ongoing review and revision of public health policies, including related
                to third or booster doses.

           h) Community transmission may persist despite high vaccination coverage, especially
                in under-vaccinated cohorts including children, who remain ineligible to receive the
                COVID-19 vaccine. Epidemiological evidence from other countries indicates that
                infection rates can worsen with new variants or easing of public health
                measures, despite high population vaccination coverage, necessitating the
                reintroduction or expansion of public health measures.

5.     Protective measures are therefore necessary to safeguard against the uncontrolled spread
       of SARS-CoV-2 in the Victorian community, to ensure that Victoria’s health system does not
       become overwhelmed, and to therefore prevent excess deaths and other harms to the
       health and wellbeing of Victorians.

How the Act Informs this Advice
6.     Section 165AB of the Act provides that a pandemic declaration may be made if the Premier
       is satisfied there is a serious risk to public health arising from a pandemic disease, or the
       outbreak or spread of a disease of pandemic potential. The period for which the declaration
       may be in force is an initial period of 4 weeks. 1 It can be extended in increments of up to
       three months. 2 There is no limit on the number of times a pandemic declaration may be
       extended.

7.     Section 3 of the Act defines the phrase “serious risk to public health” as:

1   See section 165AC(1)(c).
2   See section 165AE.

                                                    3
                                         OFFICIAL: Sensitive
a material risk that substantial injury or prejudice to the health of human beings has
        occurred or may occur having regard to:

         (a) the number of persons likely to be affected; the location, immediacy, and
               seriousness of the threat to the health of persons;

         (b) the nature, scale and effects of the harm, illness or injury that may develop; and

         (c) the availability and effectiveness of any precaution, safeguard, treatment, or other
               measure to eliminate or reduce the risk to the health of human beings.

8.   If the Premier is considering making a pandemic declaration, the Premier must consult with
     and consider the advice of the Chief Health Officer and the Minister for Health before
     making a pandemic declaration. 3 This is my advice for the purpose of that provision, and I
     have taken the Act’s definition of “serious risk to public health” into account when giving this
     advice.

Focus of my advice
9.   The primary focus of my advice is the impact that COVID-19 will have on Victorians’ health,
     and the flow-on effects that the COVID-19 pandemic will have on the health and wellbeing of
     the Victorian community.

10. In making this assessment, I am guided by the experience of the past 22 months of
     pandemic management in Victoria and the actions that the Victorian government has
     already taken. These actions have been crucial in responding to the pandemic, by
     containing SARS-CoV-2 to a degree that prevented thousands of excess deaths and
     allowed the health system to operate at tolerable capacity. These actions resulted in the
     suppression of SARS-CoV-2 transmission for a prolonged period and ensured that the
     majority of Victorians could be immunised against COVID-19 prior to substantial community
     transmission of the virus recurring. I am also guided by the experience of other Australian
     jurisdictions and other countries in attempting to manage the risks of COVID-19.

11. My advice is guided by the objectives of the Act, most relevantly, protecting public health
     and preventing disease, illness, injury, disability, or premature death. 4 It adopts an evidence-
     based approach as to the risk that COVID-19 poses and the effectiveness of precautions
     that might be used to reduce that risk. 5

12. The evidence I have used to develop my advice includes:

     (a) case data and analysis, including regarding disease severity;

3 See section 165AB(2).
4 See section 4.
5 See section 5.

(b) outbreak data and analysis;

     (c) results from available predictive, scenario-based and other modelling;

     (d) ventilation and air-flow dynamics and modelling;

     (e) established and emerging evidence from the scientific literature;

     (f) lessons from previous transmission patterns and outbreaks;

     (g) experiences from public health interventions implemented in Victoria, Australia and
          internationally;

     (h) analyses, guidance and statements from national authorities, such as the Australian
          Health Protection Principal Committee (AHPPC), Australian Technical Advisory Group on
          Immunisation (ATAGI) and Therapeutic Goods Administration (TGA), and international
          organisations such as the WHO; and

     (i) studies on vaccine effectiveness and COVID-19 vaccination data;

     (j) evidence of pharmaceutical and other clinical treatments and supports.

COVID-19 is a pandemic disease
13. Section 3(5) of the Act provides that, for the purposes of this Act, an infectious disease is a
      pandemic disease at a particular time if, at that time, there is a pandemic outbreak of that
      infectious disease.

14. There has been a pandemic outbreak of SARS-Cov-2.

15. COVID-19 was first described in Wuhan, China, in December 2019. The formal designation
      of this infectious disease in Victoria was initially 'Novel Coronavirus 2019 (2019-nCoV)'. The
      virus which causes COVID-19 is now known internationally as SARS-CoV-2.

16. Since tracking commenced on 30 December 2020, the WHO Coronavirus dashboard
      records 265,194,191 cases with 5,254,116 deaths as at 6 December 2021 6 (WHO(c)2021)

17. Since the first case was reported in Victoria on 25 January 2020 and 7 December 2021,
      there have been 130,029 confirmed cases out of an Australian total of 219,118 and 1,385
      deaths out of an Australian total of 2,056 (Australian Government Department of Health,
      2021).

6 It is also important to consider that cases and adverse health outcomes may be under reported due to either localised low
testing rates or to differences in case ascertainment criteria, and that there may be variable delays to data reporting at state,
national and global levels. For example, case detection, inclusion criteria, testing strategies, reporting practices and data cut-off
and lag times may differ between countries, territories and areas, and some of these jurisdictions may report a combination of
probable and laboratory confirmed cases (WHO(a) 2021).

                                                                 5
                                                  OFFICIAL: Sensitive
18. Since the start of the pandemic, Victoria has recorded 4,964 outbreaks involving 34,078
    confirmed cases.

19. As of 7 December 2021, Victoria has recorded 1,185 new locally acquired cases and 0 new
    overseas acquired cases and 7 deaths within the past 24 hours. There are currently 13,050
    active cases, of which 297 are in hospital, with 47 COVID-19 active patients receiving care
    in intensive care units, of whom 25 are on ventilatory support.

20. As of 7 December 2021, the 7-day average case rate for Victoria is 124 cases per 100,000
    population, which represents a 4.6% 7-day case growth rate compared to the preceding
    week. The test positivity rate for the past 7 days is 1.8%, which indicates that there is
    significant transmission of the virus in the community.

21. As of 5 December, Victoria has achieved 91.3% full vaccination coverage in those aged 12
    years and over, and 93.4% single dose vaccination coverage in this demographic.

22. Across to the WHO Coronavirus data table, only seven countries have not officially recorded
    a case of COVID-19 (WHO(c) 2021):

    (a) Democratic People’s Republic of Korea, estimated population 25,369,000 (2016)

    (b) Federal States of Micronesia, estimated population 105,000 (2016)

    (c) Kiribati, estimated population 114,000 (2016)

    (d) Nauru, estimated population 11,000 (2016)

    (e) Niue, estimated population 2,000 (2016)

    (f) Turkmenistan, estimated population 5,663,000 (2016)

    (g) Tuvalu, estimated population 11,000 (2016).

23. SARS-CoV-2 has several characteristics that make COVID-19 a pandemic disease:

    (a) SARS-CoV-2 is a novel infectious agent to which the global population had not been
        exposed prior to late 2019 (and hence had not acquired resistance), meaning that
        there was and continues to be significant immunological susceptibility for widespread
        transmission.

    (b) SARS-CoV-2 is highly transmissible and can spread easily from person to person
        through multiple modes of transmission. More detail on this issue is set out in
        paragraphs 24 to 28.

    (c) SARS, like any virus, has the capacity to mutate into more transmissible and virulent
        strains. More detail on this issue is set out in paragraphs 30 to 32.

                                                 6
                                     OFFICIAL: Sensitive
(d) Infection with SARS-CoV-2 can cause significant disease and death. More detail on this
        issue is set out in paragraphs 34 to 38.

    (e) The characteristics SARS-CoV-2 and the health effects of infection were largely
        unknown, making control difficult. Evidence is still emerging about SARS-CoV-2 and
        both the short and long-term effects of COVID-19 on the population.

    (f) There are limited preventive and therapeutic interventions to manage COVID-19 (other
        than vaccines, which are discussed in more detail below). A number of anti-viral, anti-
        inflammatory and antibody therapies have now been granted provisional approval by the
        Therapeutic Goods Administration (TGA), however many interventions against
        COVID-19 remain supportive rather than curative or preventive.

24. SARS-CoV-2 is highly infectious. It is primarily transmitted from person to person through
    respiratory droplets and aerosols carrying infectious viral particles that are inhaled or come
    into contact with the mucous membranes in a person’s eyes, nose or mouth. Transmission
    may also occur by touching contaminated surfaces and objects, known as fomites, and then
    transferring infectious particles to the eyes, nose or mouth. However, the risk of fomite
    transmission is much lower than that from droplet and aerosol transmission.

25. Respiratory droplets and aerosols are generated when the virus is expelled from an infected
    person whilst talking, coughing, sneezing, shouting, singing or even breathing, and may
    infect another person by being inhaled through the mouth or nose or inoculated directly onto
    a susceptible person’s mucous membranes. Aerosols can be generated from the routine
    behaviours outlined above, as well as by medical procedures, and can spread further than
    droplets and remain in the air for longer. Transmission is more likely in enclosed, crowded
    and poorly ventilated spaces, and where people cannot maintain physical distancing from
    others. While SARS-CoV-2 transmission is far more common indoors, it may also occur
    outdoors (Bulfone et al., 2021). These modes of transmission allow for rapid spread through
    susceptible populations and are not comprehensively understood, making it challenging to
    control the spread of the virus (WHO(d) 2021).

26. In addition, once a person is infected with SARS-CoV-2, certain characteristics of COVID-
    19, such as its incubation period and infectious period, make it more difficult to control.
    Cases can be infectious up to two days before the onset of symptoms and may be infectious
    without ever developing symptoms (it is estimated that at least a third of cases remain
    asymptomatic throughout their infection). Pre-symptomatic and asymptomatic cases can
    unknowingly transmit infection (WHO 2020).

27. The incubation period varies between people. The median incubation period is 5 to 6 days
    and ranges from 1 to 14 days. These features make it difficult to break chains of

                                                   7
                                     OFFICIAL: Sensitive
transmission without stringent public health responses, as transmission may have already
    occurred to contacts by the time a case develops symptoms and is diagnosed.

28. When determining how far a disease can spread in a population, epidemiologists use the
    basic reproduction number (R0 ), which describes how many people each infected person will
    infect on average, assuming that there is no pre-existing immunity in the community or other
    intervention to stop the spread. It takes into account the duration of contagiousness of an
    individual, the likelihood of infection in each contact between a susceptible person and an
    infectious person or vector, and the frequency of contact. In contrast, the effective
    reproduction number (Reff) refers to the number of people that can be infected by an
    individual at any specific time and may be affected by the population becoming increasingly
    immune either through natural infection or immunisation, and by mortality from the disease.
    The Reff can also be affected by changes in peoples’ behaviour including social distancing
    and other public health measures.

29. SARS-CoV-2 has an estimated R0 of around 2.63, however estimates can vary between 0.4
   and 4.6 (Mahase 2020). The R0 for Delta VOC varies between 3.2 and 6 (Liu & Rocklöv
   2021). By comparison, R0 for measles ranges from 12-18 (Guerra 2017), while the median R0
   for seasonal influenza is 1.28 (Biggerstaff 2014).

30. The SARS‑CoV‑2 virus can mutate into potentially more transmissible, virulent, and difficult
   to control variants (WHO(a) 2021), as the Delta VOC (B.1.617.2) demonstrates. Since its
   initial detection in October 2020, it has gradually spread to become the dominant strain
   globally. At the time of writing, all current cases of COVID-19 in Victoria with successful
   genomic analysis are caused by Delta VOC, as well as 99.7% of all cases worldwide in the
   60 days preceding 14 November 2021 (Agency for Clinical Innovation 2021).

31. There is now accepted evidence that the Delta VOC is more transmissible than ancestral
   SARS-CoV-2 strains, as demonstrated by the higher secondary attack rate observed in both
   household and non-household contacts of cases infected with the Delta variant. Additionally,
   there is evidence that Delta may be more virulent than other strains, as evidenced by the
   greater associated risk of hospitalisation, intensive care unit admission and death. According
   to Public Health England (PHE) data, the Delta (B.1.617.2) VOC is estimated to be 40 per
   cent more transmissible than the Alpha (B.1.17) VOC, which is itself approximately 50 per
   cent more transmissible than the ancestral Wuhan strain of SARS-CoV-2. When compared to
   the Alpha strain, infection with Delta is almost twice as likely to result in hospitalisation and
   almost three times as likely to result in ICU admission (Agency for Clinical Innovation 2021).

32. Most recently, the WHO newly designated the Omicron (B.1.1.529) strain as a VOC on 26
   November, just two days after it being initially reported. Omicron was first detected in
   samples collected on 11 November 2021 in Botswana, and subsequently in samples

                                                  8
                                      OFFICIAL: Sensitive
collected from 14 November and onward in South Africa. This strain is of concern due to its
   multiple mutations, some of which affect the spike protein, which is a key immunological
   target against the virus, and due to the coinciding surge in cases reported in South Africa
   following its detection. Although the impact of these mutations on its transmissibility,
   virulence and its capacity to evade host immune responses is not yet comprehensively
   understood, preliminary evidence suggests an increased risk of re-infection associated with
   this variant (WHO (b) 2021). As of 6 December 2021, Omicron cases have already been
   identified in Australia and in 45 other countries across the world.

COVID-19 is a serious risk to public health
33. Section 165AB of the Act provides that the Premier may make a declaration if the Premier is
    satisfied that a pandemic disease constitutes “serious risk to public health”. As noted above,
    section 3 of the Act defines the phrase “serious risk to public health” as:

       a material risk that substantial injury or prejudice to the health of human beings has
       occurred or may occur having regard to:

        (a) the number of persons likely to be affected; the location, immediacy, and
            seriousness of the threat to the health of persons;

        (b) the nature, scale and effects of the harm, illness or injury that may develop; and

        (c) the availability and effectiveness of any precaution, safeguard, treatment, or other
            measure to eliminate or reduce the risk to the health of human beings.

    This section addresses these issues.

COVID-19 has potential to cause widespread harm to many people
34. The number of persons likely to be affected, the location, immediacy, the seriousness of the
    threat to the health of persons, and the nature, scale and effects of the harm, illness or injury
    that may develop are linked, as past experiences illustrate future risk. On this basis, I will
    deal with these issues together.

35. The clinical spectrum of COVID-19 infection ranges from asymptomatic infection and mild
    respiratory symptoms through to severe illness that requires hospitalisation and may result
    in death. Vulnerable members of society, including the elderly, those with co-existing
    medical conditions (including hypertension, cardiovascular disease, respiratory disease,
    renal disease and malignancy) and those in lower socioeconomic groups, have been shown
    to be disproportionately impacted and remain at risk (Taylor et al. 2021).

36. Estimates from published literature and epidemiological sources indicate the case fatality
    rate for COVID-19 varies and can depend on the degree to which all cases of COVID-19
