Treaties - Australian Maritime Boundaries 2014a: International Treaty Boundaries

Geoscience Australia developed this digital representation of Australia's international maritime boundaries determined by treaties with neighboring countries. The data 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 latitude and 39°E to 174°E longitude. This version, AMB2014a, incorporates technical amendments based on user feedback and was published in consultation with other Commonwealth Government agencies.
