Factsheets summarise the key findings from the bioregional assessments.
Detailed information about each region is available from the relevant assessment pages.
We assessed how 22 potential new coal mines or expansions of existing coal mines could affect groundwater and surface water resources in the Hunter subregion.

The bioregional assessment found that additional coal resource development is predicted to cause minor hydrological change in the Gloucester subregion. No impacts on ecological assets are predicted in the south, given the limited additional coal resource development. In the north, potential impacts on ecological assets are expected to be minor and localised because predicted hydrological changes are small.
The bioregional assessment for the Gippsland Basin bioregion found that extending the Yallourn, Hazelwood and Loy Yang coal mines would draw down groundwater and reduce baseflow in the Latrobe River. There has been no coal seam gas production in the Gippsland Basin bioregion and limited exploration for coal seam gas.
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.
This bioregional assessment found that there is limited potential for additional coal resource development in the Central West subregion. The Ulan Mine Complex is located on the catchment boundary between the Central West and Hunter subregions. The Hunter bioregional assessment considers potential impacts to water resources from the Ulan Mine Complex, but it did not model impacts in the Central West region.
