Australian State and Territory Boundary Polygons

State Boundaries are part of the seven-theme Geoscape Administrative Boundaries dataset built from authoritative cadastre data. The dataset is maintained by Geoscape Australia and published under a CC BY 4.0 license by the Australian Department of Industry, Science and Resources. As of November 2019, data is available referenced to both the GDA94 and GDA2020 geodetic datums.

Use Cases

• Mapping state-level administrative regions using the boundary polygon geometry for national-scale visualizations.
• Joining state attribute data using the legal identifiers associated with each boundary feature.
• Analyzing spatial relationships between state territories and other administrative themes like local government areas or electoral boundaries from the full dataset.

Strengths

• Derived from authoritative government cadastre data from each state and territory jurisdiction.
• Offers coordinate data in two geodetic datums (GDA94 and GDA2020) for compatibility with different systems.
• Released under a clear, open CC BY 4.0 license negotiated by the Australian Government.

Limitations

• The specific row count, column details, and total dataset size are not provided in the metadata.
• The core descriptive metadata appears static, with a last platform update in 2026 but key references from 2019.
