Treaties - Australian Maritime Boundaries 2020 (AMB2020): International Treaty Boundaries

Treaties - Australian Maritime Boundaries Dataset 2020 is a digital representation of Australia's international maritime treaty boundaries. The dataset was published by Geoscience Australia in consultation with other Commonwealth agencies and was updated in June 2020 to include the 2018 Australia Timor-Leste Maritime Boundaries Treaty.
