The aquifer boundaries dataset depicts the major groundwater resources in Australia. This includes well known aquifers, including Great Artesian Basin, Murray Basin, Daly Basin and Perth Basin. Where possible they are attributed with their local name to allow users to identify known aquifers in an area of interest.

Aquifers are categorised as belonging to upper, middle or lower groups. This is based on the National Aquifer Framework, which groups aquifers by geological strata and age. The classification is indicative and designed to give only an indication of where complex layered aquifers occur.

The aquifer boundaries dataset is sourced from the National Groundwater Information System (NGIS). Input datasets are listed on the NGIS Copyright webpage. Detailed discussion of the methodology used is found in the Bureau's aquifer boundaries paper.
