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

Geoscience Australia's 2020 digital representation of Australia's scheduled and offshore areas under the Offshore Petroleum and Greenhouse Gas Storage Act 2006. The data covers the entire Australian marine jurisdiction from 8°S to 70°S latitude and 39°E to 174°E longitude, incorporating updates like the 2018 Timor Sea Treaty. In the event of an inconsistency between this data and the legislation, the legal text prevails.

Use Cases

• Delineating legal maritime zones for resource exploration based on the scheduled and offshore areas defined in the Act.
• Mapping Australia's marine jurisdiction for environmental impact assessments based on the geographic extent described.
• Resolving maritime boundary disputes by referencing the legislated zones, noting the data's disclaimer on legal precedence.
• Updating geographic information systems (GIS) for offshore energy projects with the 2020 version reflecting treaty changes.

Strengths

• Official data published by Geoscience Australia in consultation with Commonwealth agencies like the Attorney-General's Department.
• Updated to reflect specific legal changes, such as the 2018 Timor Sea Treaty.
• Provides a defined geographic coverage for the whole Australian marine jurisdiction, including external territories.

Limitations
