Offshore Petroleum and Greenhouse Gas Storage Act 2006 - Australian Maritime Boundaries 20

Geoscience Australia's AMB2020 is a GIS data product providing a digital representation of Australia's scheduled and offshore maritime zones as defined under the Offshore Petroleum and Greenhouse Gas Storage Act 2006. The dataset covers the entire Australian marine jurisdiction, including external territories, with a geographical extent from approximately 8°S to 70°S latitude and 39°E to 174°E longitude. It was updated in August 2019 to incorporate the 2018 Timor Sea Treaty and is published in consultation with other Commonwealth agencies.

Use Cases

• Mapping jurisdictional boundaries for greenhouse gas storage projects under the Act's offshore areas.
• Visualizing Australia's maritime claims and treaty updates, such as the 2018 Timor Sea Treaty boundaries.
• Conducting spatial analysis for marine spatial planning within Australia's exclusive economic zone and territorial sea.

Strengths

• Provides official digital representation of legislated maritime zones, developed by the authoritative national agency Geoscience Australia.
• Explicitly updated to reflect international treaty changes, including the 2018 Timor Sea Treaty and Bayu-Undan Offshore Area.
• Covers a vast spatial extent, including all Australian external territories, with coordinates provided in the GDA94 datum.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
