Australian Maritime Boundaries 2014a: Offshore Petroleum and Greenhouse Gas Storage Zones

Geoscience Australia's 2014 digital representation of Australia's scheduled and offshore areas under the Offshore Petroleum and Greenhouse Storage Act 2006. The data covers Australia's entire marine jurisdiction, including external territories, from approximately 8°S to 70°S latitude and 39°E to 174°E longitude. In the event of an inconsistency between this data and the legislation, the latter prevails.
