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

A geospatial dataset provides a digital representation of scheduled and offshore areas defined under Australia's Offshore Petroleum and Greenhouse Storage Act 2006. The data, produced by Geoscience Australia in consultation with other government agencies, covers the entire Australian marine jurisdiction from approximately 8°S to 70°S latitude and 39°E to 174°E longitude. The AMB2020 version incorporates updates such as the 2018 Timor Sea Treaty.

Use Cases

• Delineating legal maritime zones for offshore petroleum exploration based on the scheduled areas defined in the Act.
• Mapping the extent of Australia's marine jurisdiction for environmental impact assessments related to greenhouse gas storage projects.
• Visualizing maritime boundaries for legal or treaty compliance checks, incorporating updates like the Timor Sea Treaty.

Strengths

• Data is produced by the authoritative national agency Geoscience Australia in consultation with other relevant Commonwealth departments.
• The dataset has a defined geographic extent covering the whole Australian marine jurisdiction, including external territories.
• The AMB2020 version includes specific treaty updates, such as for the 2018 Timor Sea Treaty and the Bayu-Undan Offshore Area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes that in the event of an inconsistency between this data and legislative limits, the latter prevails, requiring cross-referencing with official laws.
