Overview
Postcodes Australia is a spatial data product that has been derived from a number of sources,
including:
• Advice from Australia Post - Address Management Centre
• Locality boundaries supplied by PSMA Australia Ltd
Limitations
Whilst every attempt is made to represent the postcode boundaries for Australia as accurately as
possible, Precisely is constrained to using what information is available at the time of data production.
However, Precisely intends to release updates to the Postcodes product, at least quarterly, to address
changes as they occur.
System Information
Metadata
Metadata conforming to ANZLIC standard is supplied in XML file format for the Postcodes product
range. These files can easily be viewed in a Web browser such as Microsoft Internet Explorer.
Alternatively, XML viewers are available from third party sources that readily display the hierarchical
structure of the metadata information.
Projection/Datum
The Postcodes table is provided on the GDA94 datum and projected over a longitude / latitude
coordinate system. This datum is adopted as the national standard for all spatial data.
Postcodes Australia Product Guide 4This is a geocentric datum which allows the projection to be used at a global level and facilitates, for
example, compatibility with positions derived from Global Positioning Systems (GPS satellites).
Installation
Postcodes Australia is supplied in the form of compressed files that must be extracted before use.
Before downloading the .zip file and extracting, ensure that there is enough storage space for the
data. As a guide, the zip file for the whole of Australia is about 140MB, and the extracted data requires
approximately 200MB of disk space (these sizes may increase in future releases).
To install the product, download the zip file, and extract the zipped data to your preferred location.
Note: Ensure that all license agreements are read and understood before installing the data.
Customised and other versions of Postcodes Australia are also supplied as zipped files. If you
intend using Postcodes Australia data across a network, ensure that the correct licensing
agreements have been set up. For more information regarding these licensing agreements,
contact your local Precisely office or reseller.

Gazetted Suburbs versus Australia Post Listed
Localities
There is currently limited correlation between the state jurisdiction official gazetted suburb and
localities, and the localities listed by Australia Post on its website to describe the delivery area for a
postcode. The gazetted suburb and localities are formally recognised boundaries defined by state
government, whilst Australia Post's localities can include these, but also incorporate local and alias
locality names. (Some of these names are historical but many are also created internally by Australia
Post to facilitate mail delivery.)
Generation of Precisely’s Postcodes Boundaries
Precisely's postcode boundaries are generated by combining the postcode and locality information
from the Australia Post postcode listing, with the locality information from Precisely’s Suburbs and
Localities product. The locality information in the Suburbs and Localities product contains both
gazetted suburbs and non-gazetted Localities, and is based on source from PSMA Australia Pty
Ltd's Suburbs and Localities data.
The illustration below shows how the boundary of postcode 4051 is formed by the suburb boundaries
listed.
Note: In areas where no gazetted suburbs exist, the locality boundaries are used to facilitate
full, nationwide postcode coverage.
Postcodes Australia Product Guide 8Some of the postcodes listed in the Australia Post listing are not included in the Postcodes Australia
product. Although there are exceptions, the types of postcodes that are not generally included are:
• PO Boxes that do not relate to a Delivery Area
• Large Volume Receivers (LVR) and Special Mailings (for example, Competition Mail)
• Postcodes that relate to the Antarctic Division stations

The Incremental Postcodes table contains postcode regions for those areas that have changed
between the previous release and the current release.
The Incremental table has the same structure as the AUS_PC table, but with the additional field
CHANGE_TYPE which shows the changes according to the following table:
Postcodes Australia Product Guide 10Field Name Value Description
CHANGE_TYPE I Insertion
UA Attribution Update
UB Both geometry and attribution update
UG Geometry Update
D Deletion
Deleted regions are colored purple to simplify visual identification and have the geometry and
attribution of the previous Postcodes release.
Implementation of Incremental Updates
An incremental update can be carried out using the following procedure:
1. Select records from the previous release of Postcodes data where the POSTCODE values match
those of the Incremental table and the CHANGE_TYPE = “D” or “U” (Deletion or Update
respectively)
2. Delete the selected records from the old Postcodes data.
3. Select from the new Postcodes incremental table where the CHANGE_TYPE = “I” or “U” (Insertion
or Update respectively).
4. Append the selected records to the old Postcodes data. The resulting table will contain the
updates for the current version of Postcodes, but will retain the old table structure.
