The majority of Sydney Basin is raised sandstone plateau, with the exception being the Hunter Valley and the low-lying Cumberland Plain.. Minor igneous activity took place in the basin during the Early Jurassic (i.e. 210 million years ago), Late Mesozoic (i.e. 100-90 million years ago) and Cenozoic eras (i.e. 65 million years ago).

The Oaklands Basin hosts to more than 1000 m thick sediments. The basin was first discovered in 1916 when water drillers discovered coal near Coorabin. Coal has been the main focus for exploration within the basin since this time. Extensive coal exploration drilling has been undertaken, mostly in the Coorabin area.
The coastal coal-carrying trade of New South Wales involved the shipping of coal—mainly for local consumption but also for export or coal bunkering—by sea to Sydney from the northern and southern coal fields of New South Wales. It took place in the 19th and 20th centuries.
The Illawarra Coal Measures is a group of sedimentary rocks occurring in the Sydney Basin in eastern Australia. This stratum is up to 150 metres thick. Formed in the Late Permian, it comprises shale, quartz-lithic sandstone, conglomerate rocks, and chert, with sporadically carbonaceous mudstone, coal and seams of torbanite. [1]
