Australian Maritime Boundaries GIS Data for 2014

Geoscience Australia's 2014 digital representation of Australia's maritime limits and boundaries under the Seas and Submerged Lands Act 1973. The data covers the Australian marine jurisdiction from latitudes 7°S to 70°S and longitudes 40°E to 175°E, including external territories.

Use Cases

• Analyze territorial straight baselines and outer limits for maritime zone enforcement and legal compliance.
• Map maritime boundaries determined by treaties between Australia and neighbouring countries for geopolitical analysis.
• Delineate scheduled and offshore areas under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 for resource management.
• Visualize the coastline representation within the constraints of the May 2014 source material for historical coastal studies.

Strengths

• Official data product developed by Geoscience Australia in consultation with Commonwealth agencies like the Attorney-General's Department.
• Coverage spans the entire Australian marine jurisdiction, including waters adjacent to the mainland, offshore islands, and External Territories.
• Coordinates provided in the GDA94 datum, functionally equivalent to WGS84, ensuring standardization.

Limitations

• Data currency is May 2014, making it temporally stale for current jurisdictional analyses.
• Data reflects coastline location constrained by source material available at the time of production, which may be outdated.
• In the event of inconsistency, the limits under legislation prevail over this digital representation.
