Australia's Maritime Zones and Boundaries Map from 2006

Geoscience Australia's 2006 map is a historical digital representation of Australia's territorial sea baseline and maritime limits. It describes maritime zones, boundary arrangements with neighboring countries, and the submitted limits of the extended continental shelf. This edition was superseded in 2013 and is kept for historical record only.

Use Cases

• Analyze historical maritime boundary definitions based on the Sea and Submerged Lands Act 1973
• Study international maritime agreements based on described arrangements with Indonesia, Papua New Guinea, and others
• Map the historical extent of Australia's maritime claims based on the described coverage from Heard Island to the Antarctic Territory

Strengths

• Derived from Geoscience Australia's authoritative Australian Maritime Boundaries (AMB) version 2.0 data
• Map coverage spans from Heard and McDonald Islands in the west to Norfolk Island in the east
• Includes explanations of boundary definitions and updates, and lists arrangements with five neighboring countries/entities

Limitations

• The map is superseded as of October 2013 and no longer correctly reflects current maritime zones
• Row count and column-level documentation are unknown, limiting suitability assessment
• Data currency is from 2006, which may limit contemporary analysis
