The Postcode Boundaries dataset is a result of a collaborative effort between PSMA and Australia Post.
It includes boundary and centroid (‘geometric centre’) data for some 2700 postcode boundaries across Australia.
Like PSMA’s other datasets, updates are released on a regular quarterly basis. This is important given ongoing changes to postcodes and postcode boundaries.
Applications include:
Customer and prospect analysis
Tagging postcodes to geocoded databases
Heat maps

National Postcode Boundaries
Callpoint Spatial Postcodes Extra
Our value-added edition builds on the raw PSMA data in two steps:
Amalgamation of the different State/Territory boundaries into a national edition
Addition of the following useful attribution to the Postcode Boundary polygons:
- Postcode
- Latitude/Longitude of the postcode centroid
Applications for Postcodes Extra include:
Postcode distance table creation
‘Find my nearest shop/outlet/distributor’ for visitors who enter their postcode into your website
