Australia's Maritime Jurisdiction Map for the Tasman Sea

A geospatial map delineating Australia's maritime jurisdiction zones in the Tasman Sea. It is one of 27 maps in the national series, produced by the Australian Ocean Data Network. The map depicts the extended continental shelf approved in 2008, treaties, and various maritime zones.

Use Cases

• Analyze the spatial extent of Australia's extended continental shelf boundary approved in 2008.
• Compare maritime zone boundaries, such as Exclusive Economic Zones, against bathymetric data from the 2009 9 arc-second grid.
• Reference treaty-defined maritime limits for legal or diplomatic research in the Tasman Sea region.

Strengths

• Part of a standardized national series of 27 maritime jurisdiction maps.
• Integrates bathymetric data from a specific 2009 9 arc-second grid and a 1997 grid by Smith and Sandwell.
• Includes multiple legally defined features: extended continental shelf, treaties, and maritime zones.

Limitations

• Data is presented only as a static A0-sized PDF map, limiting computational analysis.
• The underlying vector data for boundaries and zones is not provided as a separate dataset.
• Background imagery and bathymetry are derived from sources last updated in 2009 and 1997, which may be outdated.

Provenance

Source

Australian Ocean Data Network, as part of the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789).

Cartographic compilation of legal boundaries, bathymetric grids, and satellite imagery.

Time Range

The jurisdictional data reflects treaties and a continental shelf approval from April 2008.

Freshness

The map page was last updated in April 2026, but the core jurisdictional data reflects treaties and a 2008 continental shelf approval.

Geography
