Australia's Maritime Zones Map from 2006, Derived from Geoscience Australia Data

Geoscience Australia's Australian Maritime Boundaries version 2.0 data provides a digital representation of Australia's territorial sea baseline and maritime limits as established under the Sea and Submerged Lands Act 1973. This 2006 printed map shows zones and boundaries stretching from Heard and McDonald Islands to Norfolk Island and from the Torres Strait to the Australian Antarctic Territory. The map has been superseded by a 2013 edition and is kept for historical record only.

Use Cases

• Study historical maritime boundary definitions based on the described territorial sea baseline.
• Analyze international maritime agreements based on the listed boundary arrangements with Indonesia, Papua New Guinea, and other nations.
• Research submissions to the UN Commission on the Limits of the Continental Shelf based on the described extended continental shelf limits.

Strengths

• Derived from the authoritative Geoscience Australia Australian Maritime Boundaries (AMB) version 2.0 data.
• Describes maritime boundary arrangements with multiple neighboring countries, including Indonesia and Papua New Guinea.
• Specifies the map's projection (Bonne) and center coordinates (134E longitude, 30S).

Limitations

• The dataset is explicitly superseded and no longer correctly reflects Australia's maritime zones as of October 2013.
• Description metadata is limited; actual data quality requires manual inspection after download.
• The data currency is 2006, which may limit contemporary analysis.
