This bioregional assessment helps us understand how coal seam gas and coal mining development could affect water resources and water-dependent assets in the Galilee subregion. It identifies where potential impacts might occur, as well as the areas that are unlikely to be affected. The assessment is being undertaken in collaboration with the Queensland Government, which contributed funding to support this work.
About this subregion
The Galilee subregion is part of the Lake Eyre Basin bioregion and is entirely within Queensland. It extends westwards across the Great Dividing Range and into the Lake Eyre drainage basin. The subregion is sparsely populated, with most people living in towns and localities including Charleville, Barcaldine, Blackall and Hughenden.
The subregion encompasses the headwaters of several major waterways including the Cooper Creek and the Diamantina, Belyando, Cape, Thomson, Barcoo, Flinders, Bulloo, and Warrego rivers. In addition to the river systems, the subregion has numerous wetlands, springs, waterholes and lakes, including the nationally important lakes Buchanan and Galilee. Some of these are home to diverse and unique plants and animals, many of which are listed as rare or threatened under Queensland and Commonwealth legislation.
Native vegetation consists largely of grasslands in the west and open eucalyptus woodlands in the east. Cattle and sheep grazing on native pasture is the main land use and groundwater is of great importance.
Coal mining and coal seam gas operations
The geological Galilee Basin contains extensive resources of black coal. Although no commercial coal mines or coal seam gas production facilities are currently established in the subregion, six new large coal mines are scheduled to start production by 2020. Five of these coal mines will involve both open-cut and underground operations. Most of these proposed coal mines are well advanced in securing all necessary development approvals.
The development of a coal seam gas industry in the Galilee Basin is significantly less advanced than for coal with developments still being at resource appraisal stage.
About the bioregional assessment
The bioregional assessment for the Galilee subregion involves compiling background information, a water-dependent asset register and a data register. The assessment will provide the first regional-scale information about the cumulative impacts of coal resource development on water resources and water-dependent assets in the Galilee subregion. An outcome synthesis will be produced for the Galilee subregion.
