Australian State Boundaries from Authoritative Cadastre Data

Geoscape Administrative Boundaries provide legal state and territory borders for Australia, derived from authoritative cadastre data from each jurisdiction. The dataset is built and maintained by Geoscape Australia and includes seven themes, such as ABS boundaries and local government areas.

Use Cases

• Mapping state-level administrative regions based on the derived legal boundaries.

• Performing spatial analysis with data referenced to specific geodetic datums (GDA94 or GDA2020).

Strengths

• Derived from authoritative government cadastre data from each state and territory.
• Offers coordinate data in two geodetic datums (GDA94 and GDA2020) as of November 2019.
