Australian State and Territory Boundary Polygons

Geoscape Australia builds and maintains these state and territory boundaries using authoritative cadastre data from each jurisdiction. The dataset is part of a larger collection of seven administrative boundary themes, including ABS boundaries and electoral districts. Users can download the data referencing either the GDA94 or newer GDA2020 geodetic datum.

Use Cases

• Mapping state-level demographic statistics by joining ABS data to the state boundary polygons.
• Creating electoral maps by overlaying the state boundaries with federal or state electoral district polygons.
• Performing spatial analysis on infrastructure projects using the state boundary geometry as an analysis region.
• Developing location-based services that require accurate administrative region detection using the boundary coordinates.

Strengths

• Derived from authoritative government cadastre data for each state and territory.
• Offers coordinate data in two geodetic datums (GDA94 and GDA2020) for compatibility.
• Part of a dataset containing seven distinct administrative boundary themes.

Limitations

• The specific number of rows (features) and file sizes are not provided.
• The temporal coverage and update frequency for the boundary data are not specified.
• Sample data is unavailable to preview the attribute columns and geometry detail.
