Australia's Northern Maritime Jurisdiction Map

Geoscience Australia's map depicts maritime zones north of approximately 25°S, including areas around Cocos (Keeling) Islands and west of Christmas Island. It shows the extended continental shelf approved in April 2008, treaties, and various maritime zones over a bathymetric and topographic background. This map is one of 28 constituent maps in the 'Australia's Maritime Jurisdiction Map Series' (GeoCat 71789).

Use Cases

• Verifying legal maritime boundaries for policy or treaty analysis based on depicted zones.
• Planning marine resource management activities using the bathymetry and jurisdictional overlay.
• Producing large-format reference maps for educational or institutional use from the 3277mm x 1050mm PDF.
• Conducting regional geospatial analysis of Australia's northern maritime jurisdiction.

Strengths

• Part of a standardized series of 28 maps providing systematic coverage of Australia's maritime jurisdiction.
• Integrates authoritative data sources, including the 2008 Commission-approved continental shelf limits and 2009 Geoscience Australia bathymetry.
• Available in a high-resolution, large-format PDF (3277mm x 1050mm) suitable for professional plotting.

Limitations

• Metadata is incomplete; specific column names, row counts, file size, license, and author information are not provided.
• The dataset's primary format is a static PDF image, limiting direct geospatial analysis without digitization.
• Update timestamps conflict between sources (2026-04-20 and 2026-03-25), creating uncertainty about the most recent version.
