Australia's 3D Geological Framework for Groundwater Systems Atlas

Geoscience Australia developed a preliminary national-scale 3D geological model integrating data from 53 sources and 171,000 drillholes. The model depicts the distribution, depth, thickness, and characteristics of aquifers and aquitards across eight geological time slices. It supports a collective understanding of basin architecture and groundwater connectivity for water sustainability decision-making.

Use Cases

• Modeling national groundwater flow paths based on integrated aquifer and aquitard characteristics.
• Analyzing aquifer connectivity and basin architecture based on 3D geological time slices.
• Supporting environmental policy and water use decisions based on improved groundwater system understanding.
• Standardizing stratigraphic nomenclature and data integration across disciplines at a national scale.

Strengths

• Integrates data from 53 national sources and 171,000 drillholes.
• Includes depth surfaces for eight geological time slices from surface to crystalline basement.
• Funded through major national initiatives (Exploring for the Future, Resourcing Australia's Prosperity).

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 or source bias inherent to data_gov_au.
