Australia's Maritime Jurisdiction in the Timor Sea, 2019 Treaty Update

One map in the 27-constituent 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789). The map, produced by Geoscience Australia, was updated in December 2019 to reflect the 2018 Australia-Timor-Leste Maritime Boundaries Treaty. It depicts Australia's continental shelf as proclaimed in the 2012 proclamation under the Seas and Submerged Lands Act 1973.

Use Cases

• Visualizing maritime treaty boundaries based on the 2018 Australia-Timor-Leste treaty mentioned in the description
• Analyzing continental shelf extents based on the 2012 proclamation referenced in the description
• Referencing indicative maritime zone limits for background mapping based on the described territorial sea baselines
• Incorporating composite bathymetric background imagery based on the described GA and Smith and Sandwell grids

Strengths

• Part of a defined 27-map series (GeoCat 71789), providing a structured collection context
• Explicitly updated to reflect a specific international treaty (the 2018 Australia-Timor-Leste Maritime Boundaries Treaty)
• Background imagery is derived from specific, cited sources (2009 GA grid and Smith and Sandwell, 1997)

Limitations

• The map is described as 'indicative only' and 'should NOT be used as a definitive source of information'
• Column-level documentation is absent; field semantics must be inferred after download
• Last updated 2026-04-30 13:29:30.287163; freshness should be verified
