Map showing major NSW sedimentary basinsOver 60% of New South Wales is covered by sedimentary basins. In the east is the coal-rich Permian-Triassic Sydney-Gunnedah-Bowen Basin system. It is overlain by the gas-prospective Jurassic-Cretaceous Great Australian Basin, comprising the Clarence-Moreton Basin, Surat Basin and Eromanga Basin. To the west, the largely Devonian gas-prospective Darling Basin is overlain by the Great Australian Basin and the Cenozoic Murray Basin. Older infra-basins, such as the Oaklands Basin, Gilgandra Sub-Basin and Paka Tank Trough are prospective for coal and gas.
