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, from approximately 8°S to 70°S latitude and 39°E to 174°E longitude, and was published in May 2014. Data coordinates are supplied in the GDA94 datum and the product is available as an ESRI Geodatabase and REST web service.
