Australia's Maritime Jurisdiction North of 25°S, Updated per 2018 Treaty

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 Cocos (Keeling) Islands and Christmas Island. The background combines bathymetric and topographic imagery from Geoscience Australia and other sources.

Use Cases

• Analyzing changes in maritime boundaries based on the 2018 Australia/Timor-Leste treaty mentioned in the description.
• Visualizing the extent of Australia's continental shelf as proclaimed in the 2012 proclamation.
• Integrating bathymetric context for marine spatial planning using the described background imagery.
• Studying the jurisdictional areas around offshore territories like Cocos (Keeling) Islands and Christmas Island.

Strengths

• Explicitly updated in December 2019 to incorporate a major international treaty (2018 Australia/Timor-Leste Maritime Boundaries Treaty).
• Part of a standardized map series comprising 28 constituent maps, suggesting a systematic approach.
• Background incorporates specific, cited data sources: 2009 9 arc second bathymetry/topographic grid and a 1997 grid by Smith and Sandwell.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2026-06-05 07:34:22.750331; freshness should be verified as the underlying treaty and data are older.
