Abstract
Across Australia, groundwater is a vital resource that supports and strengthens communities, culture, the environment and numerous industries. Movement of groundwater is complicated, taking place horizontally, vertically and across different timescales from weeks to millions of years. It is affected by changes in climate, human use, and geological complexities such as the type, geometry and distribution of rocks. Understanding how all these factors interact is known as a groundwater conceptual model and it is an important first step. This groundwater conceptualisation includes the Galilee Basin and the overlying Eromanga and Lake Eyre basins and other Cenozoic units as well as surface-groundwater interactions. Figure 1 shows the locations of the cross sections used to conceptualise groundwater in the Galilee Basin region. In the Galilee Basin extended region this includes 1 aquifer in the Lake Eyre Basin, 5 aquifers in the Eromanga Basin and 3 aquifers in the Galilee Basin (Wainman et al., 2023a, b). Confidence for each aquifer was calculated for both salinity and water levels (Hostetler et al., 2023a, b, c). The confidence for each aquifer was added to show the overall confidence for the basin. The level of knowledge across all aquifers are moderate to low. The groundwater conceptualisations summarise the groundwater flow and potential connectivity between aquifers. Figures also show the distribution of the aquifers and aquitards, average salinity, potential aquifer yield and confidence over an area of 50 km along the cross section lines.

Lineage
This package has been developed as part of the the Trusted Environmental and Geological Information program (TEGI), and is providing better and more streamlined access to information and data for geological basins prospective for energy, carbon capture and storage, groundwater and minerals. The program has identified and collated trusted baseline data and information for four prospective basin regions and supplement it with new geological and environmental assessments. This information will provide Australian governments, industry and communities with the highest-quality trusted science available to make faster, clearer decisions and provide better outcomes for the environment and water resources.
