Australia's Maritime Zones and Boundaries Map from 2006

A historical geospatial map depicting Australia's maritime zones and international boundaries as defined in 2006. The map was derived from Geoscience Australia's Australian Maritime Boundaries version 2.0 data and is based on the Sea and Submerged Lands Act 1973. It has been superseded by a 2013 edition and is kept for historical record only.

Use Cases

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

Strengths

• Provides a historical snapshot of Australia's maritime claims as of 2006.
• Includes descriptions of boundary arrangements with multiple neighboring countries and territories.
• Covers a wide geographic extent from Heard and McDonald Islands to Norfolk Island and the Australian Antarctic Territory.

Limitations

• The data is explicitly noted as superseded and no longer correctly reflects current maritime zones.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
