Treaties - Australian Maritime Boundaries 2014a: International Treaty Boundaries

Geoscience Australia's Treaties - Australian Maritime Boundaries Dataset 2014a is a digital representation of Australia's international maritime boundaries determined by treaties with neighbouring countries. The dataset covers the entire Australian marine jurisdiction, including waters adjacent to the mainland, offshore islands, and External Territories, with a geographical extent from approximately 8°S to 70°S and 39°E to 174°E. It was published in May 2014, with coordinates supplied in the GDA94 datum.

Use Cases

• Mapping maritime jurisdiction zones based on treaty-defined boundaries.
• Analyzing maritime spatial planning based on the defined international boundaries.
• Supporting legal and diplomatic research on Australia's maritime treaties.
• Integrating treaty boundaries with other marine datasets for jurisdictional analysis.

Strengths

• Developed by Geoscience Australia in consultation with other Commonwealth Government agencies, including the Attorney-General's Department and the Department of Foreign Affairs and Trade.
• Includes technical amendments based on user feedback, such as harmonization of datasets in block SC51.
• Provides a digital representation of official treaty boundaries, with a defined geographical coverage and coordinate datum (GDA94).

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.
• Last updated 2026-04-30 14:38:37.335634; freshness should be verified as the underlying data is from 2014.
