Australia's Maritime Zones and Boundaries, 2006 Historical Map

A historical map from Geoscience Australia depicting Australia's maritime zones and boundaries as of 2006. It is derived from the Australian Maritime Boundaries (AMB) version 2.0 data, representing the territorial sea baseline and limits established under the Sea and Submerged Lands Act 1973. The map covers zones from Heard and McDonald Islands to Norfolk Island and from the Torres Strait to the Australian Antarctic Territory.

Use Cases

• Analyze international maritime agreements based on listed arrangements with Indonesia, Papua New Guinea, and others.
• Research the process of defining an extended continental shelf based on the description of submissions to the UN Commission.

Strengths

• Derived from an authoritative source, Geoscience Australia's Australian Maritime Boundaries (AMB) version 2.0 data.
