Postcode Boundaries

The definitive set of postcodes developed by Australia Post and PSMA Australia.

Postcodes are integral to mailing addresses and are used in a wide range of spatial aggregation and analysis activities.

The Postcode Boundaries dataset is the definitive set of postcodes developed by Australia Post and PSMA Australia. It includes postcode boundaries (polygon data) and postcode centroids (point data).


Postcodes are allocated to geographic areas to facilitate the efficient processing and delivery of mail to customers. The Postcode Boundaries dataset represents postcodes as both a polygon and a point.
