The Great Artesian Basin (GAB) is one of the largest artesian groundwater basins in the world. It underlies approximately one-fifth of Australia and extends beneath arid and semi-arid regions stretching from the Great Dividing Range to the Lake Eyre depression. The water from the GAB continues to be of vital importance to outback regions of Queensland. They often rely solely on this supply for domestic and farming requirements, irrigation, mining, and other essential industries.
