Australian Maritime Boundaries Under Offshore Petroleum Act 2020

AMB2020 is a GIS data product providing a digital representation of Australia's scheduled and offshore areas as defined under the Offshore Petroleum and Greenhouse Gas Storage Act 2006. The dataset covers the entire Australian marine jurisdiction, with geographical extents from 8°S to 70°S latitude and 39°E to 174°E longitude, and was updated in August 2019 to incorporate the 2018 Timor Sea Treaty.

Use Cases

• Analyze the spatial extents of scheduled and offshore areas for resource management and planning under the Offshore Petroleum and Greenhouse Gas Storage Act 2006.
• Integrate maritime zone boundaries with other marine spatial data for jurisdictional analysis of Australia's marine jurisdiction.
• Update maritime boundary layers in GIS systems to reflect changes from the 2018 Timor Sea Treaty, including the Bayu-Undan Offshore Area.

Strengths

• Official digital representation of Australia's maritime zones developed by Geoscience Australia in consultation with key government agencies.
• Geographical coverage spans the entire Australian marine jurisdiction, including waters adjacent to the mainland, offshore islands, and External Territories.
• Data is provided in ESRI Geodatabase format with coordinates in the GDA94 datum, which is functionally equivalent to WGS84.

Limitations

• The dataset is a digital representation; in the event of an inconsistency, the limits under the legislation prevail over the data.
• Currency is August 2019, which may not reflect subsequent legal or treaty changes.
