Australian Maritime Boundaries 2014a: GIS Data for Legal and Petroleum Zones

Geoscience Australia's Australian Maritime Boundaries (AMB) 2014a data is a digital GIS representation of Australia's maritime limits and boundaries. The data delineates zones under the Seas and Submerged Lands Act 1973 and includes limits for State and Territory scheduled areas under the Offshore Petroleum and Greenhouse Gas Storage Act 2006. Coverage spans the Australian marine jurisdiction from approximately 7°S to 70°S latitude and 40°E to 175°E longitude, with coordinates in the GDA94 datum.

Use Cases

• Mapping territorial sea baselines and exclusive economic zones based on the legal delineation described.
• Analyzing offshore petroleum and greenhouse gas storage lease areas based on the scheduled area limits.
• Visualizing international maritime boundaries determined by treaties with neighboring countries.
• Supporting coastal zone management and planning based on the representation of coastal waters limits.

Strengths

• Developed by the authoritative national agency Geoscience Australia in consultation with other Commonwealth departments.
• Provides a consolidated digital representation of multiple legal maritime zones and petroleum act limits.
• Coverage includes Australia's mainland, offshore islands, and all external territories.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The data currency is May 2014, which may not reflect recent legal or geographical changes.
