Bioregional Assessment Programme

A map of southeast Australia showing the six bioregions in the Bioregional Assessment program. These bioregions are Lake Eyre Basin, Northern Inland Catchments, Clarence-Moreton Basin, Northern Sydney Basin, Sydney Basin and Gippsland Basin.

To respond to community concerns about the potential water-related risks from coal seam gas (CSG) and large coal mining developments, the Australian Government is ensuring that regulatory decisions are informed by improved science and independent expert advice.

To better understand the potential impacts of CSG and large coal mining developments on our water resources, scientific investigations - called bioregional assessments - are being undertaken in selected regions.

Bioregional assessments are world-first science-based studies that will develop detailed, multi-layered records of the environment and provide all interested parties with a comprehensive suite of baseline information and analysis about water resources in their region.

The assessments will examine the possible impacts of CSG and large coal mining developments on water resources, above and below ground. This includes potential direct, indirect and cumulative impacts of all likely mining developments in the area.

The Bioregional Assessment programme is being undertaken as an inter-agency government partnership between the Department of the Environment, Geoscience Australia, the Bureau of Meteorology and the CSIRO.

Primarily, the purpose of these assessments is to inform the Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development in the following bioregional assessment areas:

  • Lake Eyre Basin
  • Northern Inland Catchments
  • Clarence-Moreton Basin
  • Northern Sydney Basin
  • Sydney Basin
  • Gippsland Basin.

The suite of currently identified bioregional assessments will be finalised in late 2016.
