Great Artesian Basin water resource assessment

Last updated:10 December 2021

Project completed 2012


Funded by the then Australian Government Department of Sustainability, Environment, Water, Populations and Communities and the National Water Commission, the Great Artesian Basin Water Resource Assessment (the Assessment) was completed in 2012. The Assessment carried out a basin-scale investigation of water resources across the GAB, assessing the status of water resources, identifying the potential impacts of climate change and resource development on those water resources and filling knowledge gaps in our understanding of the resource. The Assessment provides an updated interpretation of the geology and hydrogeology of the GAB that has refined the conceptualisation of how the groundwater system operates.
