Eastern Australia 3D Geological and Hydrogeological Surfaces Update

Eastern Australian basins feature updated 3D geological and hydrogeological surfaces from the Great Artesian Basin to offshore southern basins. The dataset presents a second iteration of surfaces for 18 region-wide hydrogeological units, incorporating new borehole and geophysical data. This work was completed by Geoscience Australia as part of the Exploring for the Future Program.

Use Cases

• Model groundwater flow and storage based on updated 3D hydrogeological unit surfaces.
• Reconcile regional geological studies based on a common stratigraphic framework mentioned in the description.
• Support integrated resource assessments based on the regional geological context provided.
• Inform sustainable groundwater management decisions based on basin-wide hydrogeological framework data.

Strengths

• Covers a vast study area extending from the Gulf of Carpentaria to southern offshore basins.
• Updates surfaces and thicknesses for 18 specific hydrogeological units.
• Incorporates new data types including legacy boreholes, 2D seismic, and airborne electromagnetic (AEM) data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific eastern Australian basins covered.
