AMB2014a: Australia's International Maritime Treaty Boundaries

May 2014 digital representation of Australia's international maritime boundaries determined by treaties with neighbouring countries. The dataset, developed by Geoscience Australia in consultation with other government agencies, covers the entire Australian marine jurisdiction from approximately 8°S to 70°S and 39°E to 174°E. It is provided in GDA94 datum as an ESRI Geodatabase and includes technical amendments based on user feedback.

Use Cases

• Delineating national jurisdiction for resource exploration based on treaty-defined maritime boundaries.
• Mapping legal maritime zones for maritime law enforcement and surveillance activities.
• Resolving spatial inconsistencies in maritime claims by referencing the authoritative treaty limits.
• Providing a foundational geospatial layer for marine spatial planning and environmental management.

Strengths

• Developed by the authoritative national agency Geoscience Australia in consultation with other relevant Commonwealth departments.
• Includes technical amendments made on the basis of user feedback, such as harmonisation in block SC51.
• Provides explicit geographic coverage coordinates (8°S to 70°S, 39°E to 174°E) and a specific currency date (May 2014).

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.
