Illawarra Coal Measures

The Illawarra Coal Measures is a group of sedimentary rocks occurring in the Sydney Basin in eastern Australia.

Formed in the Late Permian, it comprises shale, quartz-lithic sandstone, conglomerate rocks, and chert, with sporadically carbonaceous mudstone, coal and seams of torbanite.
