Australia's Maritime Jurisdiction in the Timor Sea

Geoscience Australia's map depicts Australia's maritime jurisdiction in the Timor Sea, updated in December 2019 to reflect the 2018 Australia-Timor-Leste Maritime Boundaries Treaty. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' and shows the continental shelf as proclaimed in the 2012 Proclamation. The map combines bathymetric data from a 2009 grid and land imagery from NASA's Blue Marble but is indicative only and not a definitive legal source.

Use Cases

• Visualizing treaty-defined maritime boundaries based on the 2018 Australia-Timor-Leste agreement.
• Referencing the indicative outer limits of Australia's continental shelf as proclaimed in 2012.
• Incorporating composite bathymetric and topographic background imagery for regional map creation.

Strengths

• Updated to reflect a specific international treaty (the 2018 Australia-Timor-Leste Maritime Boundaries Treaty).
• Part of a standardized national map series comprising 27 constituent maps.
• Background imagery synthesizes data from authoritative sources like Geoscience Australia's 2009 grid and NASA.

Limitations

• Explicitly described as 'indicative only' and 'should NOT be used as a definitive source of information'.
• Metadata fields such as license, author, and row/size details are consistently missing or listed as 'None'.
• Conflicting 'last updated' timestamps (2026-04-20, 2026-03-25) suggest potential metadata management issues.
