Postcode Boundaries
The definitive set of Australian postcodes and their geographic boundaries.
The Postcode Boundaries dataset is the definitive set of Australian postcodes and their geographic boundaries.
It enables a wide range of spatial aggregation and analysis activities, including the visualisation of postcode areas.
Postcodes are integral to mailing addresses. They’re allocated to geographic areas to facilitate the efficient processing and delivery of mail.
The dataset includes two data layers:
- Postcode boundaries (polygon data)
- Postcode centroids (point data).
