Australian Maritime Search And Rescue Region Boundaries

Geospatial data defines Australia's maritime jurisdiction and Search and Rescue Region boundaries. The map was produced for the Australian Customs Service and updated in 2019 to incorporate the 2018 Australia Timor-Leste Maritime Boundaries Treaty. It is hosted by the Australian Ocean Data Network.

Use Cases

• Delineating the Search and Rescue Region for operational planning using the provided boundary polygons.
• Analyzing changes in maritime jurisdiction by comparing the 2012 confirmed continental shelf areas with the 2019 treaty updates.
• Mapping Australia's maritime claims, including confirmed and unconfirmed continental shelf areas, for legal and policy research.

Strengths

• Updated in 2019 to reflect a major international treaty (2018 Australia Timor-Leste Maritime Boundaries Treaty).
• Produced for an authoritative government agency (Australian Customs Service).

Limitations

• Data is presented only in static HTML and PDF map formats, limiting programmatic analysis.
• The underlying vector data (rows, columns, geometry types) is not directly accessible.
