Australia's Maritime Search and Rescue Region Boundaries

Geoscience Australia Data provides a 2019-updated map delineating Australia's maritime jurisdiction for search and rescue and border protection. The dataset reflects changes from the 2018 Australia Timor-Leste Maritime Boundaries Treaty and includes simplified legend information for confirmed and unconfirmed areas.

Use Cases

• Analyze the spatial extent of Australia's Search and Rescue Region for maritime safety planning.
• Compare confirmed and unconfirmed maritime boundary areas as depicted in the map legend.
• Study the impact of the 2018 Australia Timor-Leste Maritime Boundaries Treaty on jurisdictional maps for border protection.

Strengths

• Updated in 2019 to incorporate a major 2018 international treaty.
• Produced by the authoritative national geoscience organization, Geoscience Australia Data.
• Includes both confirmed and unconfirmed maritime areas as per the simplified legend.

Limitations

• Data is provided only in HTML and PDF formats, limiting direct geospatial analysis.
• The underlying source data and specific coordinate geometries are not directly accessible.
• The description references another related record (eCat 132906) for a version without the SAR zone, indicating potential versioning complexity.
