Australia's Maritime Jurisdiction Map North of 25 Degrees South

A geospatial map depicts Australia's maritime jurisdiction north of approximately 25 degrees South latitude. The map is part of a 28-map series published by the Australian Ocean Data Network and was updated in April 2026. It includes the extended continental shelf approved in 2008, treaty boundaries, and zones around Cocos (Keeling) Islands and Christmas Island.

Use Cases

• Analyze the spatial extent of Australia's continental shelf boundaries approved by the CLCS in 2008.
• Compare maritime zones, such as the Exclusive Economic Zone (EEZ), around Cocos (Keeling) Islands and west of Christmas Island.
• Use the background bathymetry data derived from Geoscience Australia's 9 arc second grid and Smith & Sandwell's 1997 grid for seafloor topography studies.

Strengths

• Part of a standardized series of 28 constituent maps providing consistent jurisdictional coverage.
• Background incorporates bathymetry data from two authoritative sources: Geoscience Australia (2009) and Smith & Sandwell (1997).
• High-resolution print-ready PDF sized for a 42-inch plotter (3277mm x 1050mm).

Limitations

• Data is provided only as static map images (PDF, HTML), not as machine-readable vector features or tabular coordinates.
• The temporal coverage for the jurisdictional claims is not continuously updated; the core continental shelf data reflects a 2008 approval.
• No sample data or column schema is available to understand the underlying attribute data for the maritime zones.

Provenance

Source

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

Collection Method

Cartographic compilation of legal boundaries, treaties, and geophysical data.

Time Range

The continental shelf boundaries reflect the April 2008 approval by the Commission on the Limits of the Continental Shelf (CLCS).

Freshness

The metadata record was last updated in April 2026.

Geography

Covers maritime areas north of 25°S, including zones contiguous to the Australian continent and around Cocos (Keeling) Islands and Christmas Island.
