Sydney Basin Hydrogeological Inventory with Geological and Management Attributes

Geoscience Australia Data provides a hydrogeological inventory for the Sydney Basin, a geological structure formed from the Late Carboniferous to Middle Triassic periods. The dataset groups descriptive attributes into themes including location, demographics, physical geography, surface water, geology, hydrogeology, groundwater management, land use, and scientific stimulus. It was last updated on 2026-03-25.

Use Cases

• Map groundwater management zones based on administrative and hydrogeological boundaries.
• Model subsurface water flow based on described stratigraphy and geological structures like the Lapstone Monocline.
• Assess environmental and land use impacts on aquifers using grouped attribute themes for industry and surface water.
• Study coal deposit distribution and host rock geology within the described Southern, Central, Western, Newcastle, and Hunter coalfields.

Strengths

• Dataset is structured around 11 specific thematic groups including hydrogeology, groundwater management, and land use.
• Provides detailed geological context including formation periods (Late Carboniferous to Middle Triassic) and maximum burial depths (2,000 to 3,000 metres).
• Spatially bounded by features in an associated Hydrogeology Index map, suggesting geospatial integration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may complicate automated analysis.
