This bioregional assessment identifies current and future coal and coal seam gas resources and developments, as well as water-dependent assets in the Sydney Basin bioregion.
At a glance
The Sydney Basin provides water for over five million people and coal for local and international markets. There is also coal seam gas extraction at Camden.
About the bioregion
The Sydney Basin bioregion adjoins the Northern Sydney Basin bioregion, and extends from Capertee in the north to Durras on the south coast of New South Wales. Major rivers in the Sydney Basin bioregion include the Hawkesbury River and its main tributary the Nepean River, as well as the Georges and the Shoalhaven rivers.
The Sydney Basin bioregion includes Australia’s largest city, Sydney, as well as the cities and towns of Wollongong, Bowral, Moss Vale, Nowra and Lithgow. It also includes significant parts of the Blue Mountains, Wollemi and Moreton national parks.
