Australia's Maritime Zones Edition 4: Territorial Sea and Continental Shelf Limits

Australia's Maritime Zones Edition 4 is a digital map derived from Geoscience Australia's Australian Maritime Boundaries version 2.0 data. It represents Australia's territorial sea baseline, maritime limits, and boundaries established under the Sea and Submerged Lands Act 1973, including continental shelf limits confirmed in 2008. The map is published by the Australian Ocean Data Network and was updated as a web map in 2013.

Use Cases

• Analyze the extent of Australia's maritime jurisdiction based on the described territorial sea baseline and limits.
• Study international boundary agreements based on the listed arrangements with Indonesia, Papua New Guinea, Solomon Islands, France, and New Zealand.
• Map unresolved continental shelf areas based on the zones described as 'yet to be resolved'.
• Visualize the geographic scope of Australia's maritime claims stretching from Heard and McDonald Islands to Norfolk Island and the Australian Antarctic Territory.

Strengths

• Based on the authoritative Australian Maritime Boundaries (AMB) version 2.0 data from Geoscience Australia.
• Incorporates continental shelf limits confirmed by the Commission on the Limits of the Continental Shelf on 9 April 2008.
• Lists specific maritime boundary arrangements with five neighboring countries and territories.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2026-06-16 20:59:18.523461; freshness should be verified as the underlying data is from 2013.
• Column-level documentation is absent; field semantics must be inferred after download.
