Maritime Jurisdiction Map of Australia's Tasman Sea

2026-03-07 updated map from Geoscience Australia depicting Australia's maritime jurisdiction in the Tasman Sea. It is one of 27 constituent maps in a national series, showing the extended continental shelf approved in 2008, treaties, and maritime zones over bathymetric and topographic data.

Use Cases

• Analyze the spatial extent of Australia's extended continental shelf in the Tasman Sea for legal and policy research.
• Overlay maritime zones and treaty boundaries from the map with vessel tracking data for maritime enforcement planning.
• Use the bathymetric background imagery derived from 2009 9 arc-second and 1997 Smith and Sandwell grids for seafloor morphology studies.

Strengths

• Part of a standardized national map series comprising 27 constituent maps.
• Integrates authoritative legal boundaries (2008 continental shelf approval) with scientific bathymetric data.
• Background imagery combines high-resolution 2009 9 arc-second bathymetric/topographic data with a 1997 global grid.

Limitations

• Data is static and represented as a PDF/A0 map, not a machine-readable geospatial dataset (e.g., GeoJSON, Shapefile).
• Temporal coverage is mixed, with legal boundaries from 2008 and background grids from 1997 and 2009, limiting currentness for some features.
