Australia's Maritime Jurisdiction Map North of 25°S, Updated 2019

Geoscience Australia's map depicts Australia's maritime jurisdiction north of approximately 25°S, updated in December 2019 to reflect the 2018 Australia/Timor-Leste Maritime Boundaries Treaty. It is one of 28 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' and includes areas around the Cocos (Keeling) Islands, Christmas Island, and the northern continent. The background combines bathymetry from Geoscience Australia (2009) and Smith & Sandwell (1997) with land imagery from NASA's Blue Marble.

Use Cases

• Visualizing maritime treaty boundaries based on the 2018 Australia/Timor-Leste treaty update.
• Analyzing continental shelf extents based on the Seas and Submerged Lands Act 1973 proclamation.
• Mapping jurisdictional areas for marine spatial planning around Cocos (Keeling) Islands and Christmas Island.
• Incorporating bathymetric and topographic background layers for maritime context.

Strengths

• Updated in December 2019 to reflect a specific international treaty (2018 Australia/Timor-Leste Maritime Boundaries Treaty).
• Part of a standardized series of 28 constituent maps providing systematic coverage.
• Background imagery combines authoritative sources from Geoscience Australia and NASA.

Limitations

• Description metadata is limited; actual data quality and format require manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
