Australia's Maritime Zones and Continental Shelf Limits, 2013 Edition

Australia's maritime zones and boundaries, derived from Geoscience Australia's Australian Maritime Boundaries version 2.0 data. The map shows the territorial sea baseline, limits established under the Sea and Submerged Lands Act 1973, and continental shelf limits confirmed in 2008. It covers areas from Heard and McDonald Islands to Norfolk Island and the Australian Antarctic Territory.

Use Cases

• Mapping Australia's territorial sea and exclusive economic zone based on the described legal baselines.
• Analyzing continental shelf claims, including resolved and unresolved areas mentioned in the description.
• Studying bilateral maritime boundary arrangements with Indonesia, Papua New Guinea, and other nations listed.
• Visualizing the geographic extent of Australia's maritime jurisdiction from the Antarctic Territory to the Torres Strait.

Strengths

• Derived from the authoritative Australian Maritime Boundaries (AMB) version 2.0 dataset.
• Incorporates continental shelf limits confirmed by the UN Commission on the Limits of the Continental Shelf in April 2008.
• Explicitly lists maritime boundary arrangements with multiple neighboring countries and territories.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying data currency is 2013, which may not reflect recent boundary changes or disputes.
