It literally was a basin more than 190 million years ago and was open to the sea. it stretched from around Port Stephens in the north, inland to where Lithgow is today and south down the coast to around Nowra! Then over that 190 million year period the basin silted up forming sandstone and shale formations. The underlying vegetation and marine life fossilized and compressed to become the valuable coal seams being mined in the Sydney basin today. Then sections of the basin buckled around 12 million years ago to become the Blue Mountains.

Unfortunately Australia exports most of its coal rather than using it domestically for cheap electricity, industrial manufacturing, and full well paid employment.
