Petroleum Geology of Offshore Basins

Australia is relatively under-explored by international standards. Continued exploration is enabled through the Australian Government’s annual release of offshore acreage. Geoscience Australia supports these releases and ongoing investment in exploration with a suite of regional petroleum geological information sets, comprising summaries on stratigraphy, petroleum systems, exploration histories and key references. Also included are various thematic maps and figures. The available information is organised according to the major sedimentary basins and can be accessed by selecting the region of interest on the left. These pages will undergo regular updates and will be expanded to provide information for all Australian offshore basins.

Information on Australia's onshore and offshore sedimentary basins is also available from Geoscience Australia's Australian Geological Provinces Database. This database can be interactively queried and the results retrieved as reports and maps.
