Postcode Boundaries¶
Disclaimer
Overview¶
The Postcodes Boundaries dataset is Australia’s most definitive set of Postcodes developed by Australia Post and Geoscape Australia. The Postcode Boundaries dataset represents postcodes as both a polygon (postcode boundaries) and a point (postcode centroid). For more information, please refer to the Postcode Boundaries Product Description. Geoscape welcomes your feedback on the Postcode Boundaries product. We also publish regular product development updates on our website ( www.geoscape.com.au ).

Change Notifications¶
Removal of the ‘Documents’ folder from data packages¶
Geoscape has moved product descriptions, guides and reports online to https://docs.geoscape.com.au Data packages no longer include the ‘Documents’ folder.
Updates¶
General¶
The QA process highlighted the existence of multi-part Postcode polygons, some of these spanning significant distances.
A small number of gazetted localities were identified that do not currently have postcodes assigned. These will be submitted to postcode allocation and if successful, included in future updates.
A postcode polygon is considered to have changed if its geometry has changed by ‘0.00005’.
A few localities, each of them is serviced by multi-Delivery offices, have not been allocated postcodes, for instance, “Blue mountains National Park” in NSW.
Northern Territory¶
Marine parks near Darwin have not been allocated postcodes. These are non-delivery areas and will only serve to overstate the total area covered by the postcode and any “per square km” statistics generated from them.
Queensland¶
The localities of South Talwood and North Talwood have been combined to form the new locality of Talwood (locality_pid = ‘locyrKBCfawRgZv’). This has resulted in a reduction in the locality_postcode table count by 1 record.
Some localities in QLD are unable to be allocated postcodes at this time. Examples include “Upland”, “Ward” and “Selwyn”.
Marine parks have not been allocated postcodes. These are non-delivery areas and will only serve to overstate the total area covered by the postcode and any “per square km” statistics generated from them.
South Australia¶
Commonwealth Hill allocated to 5719 (previously NA postcode).
Lockes Claypan allocated to 5655 (previously NA postcode).
The above allocations have resulted in the removal of the NA postcode in SA. This has resulted in a reduction in the postcode, postcode_polygon and postcode_point counts by 1 each.
Future Considerations¶
This section outlines enhancements or changes under consideration, but not planned into a specific release. For further details on future initiatives, please contact Geoscape Support.
Western Australia¶
The North-western coastline has excessive detail and may be simplified in a future release. At this time this area is excluded from topology change comparison. Visual inspection indicates minimal changes to this remote region.

Edits to the Postcode Points and Postcode Polygons theme are generally geometry recalculations required after the geometry from associated locality boundaries were edited.
