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

Australia's maritime jurisdiction north of 25°S, updated in December 2019 to reflect the 2018 Australia/Timor-Leste treaty. The map is part of a series by Geoscience Australia and includes areas around Cocos (Keeling) Islands and Christmas Island. It depicts the continental shelf as proclaimed in 2012 and uses bathymetric and topographic data from Geoscience Australia and other sources.

Use Cases

• Analyze maritime boundaries based on the 2018 Australia/Timor-Leste treaty update.
• Map the extent of Australia's continental shelf based on the 2012 proclamation.
• Study bathymetric features in northern Australian waters based on the combined background grid.

Strengths

• Map was updated in December 2019 to reflect a specific treaty (Australia/Timor-Leste 2018).
• Background bathymetry is derived from a combination of 2009 Geoscience Australia data and a 1997 global grid.
• Map is part of a standardized series of 28 constituent maps (GeoCat 71789).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update is listed as 2026-06-17.
