Port Phillip-Westernport Basin Hydrogeological Inventory for South-Central Victoria

Geoscience Australia Data provides a hydrogeological inventory for two small, shallow sedimentary basins formed during the Late Cretaceous rifting of Australia and Antarctica. The dataset groups descriptive attributes into themes including location, geology, hydrogeology, groundwater management, and land use. It was last updated on 2026-04-20.

Use Cases

• Model groundwater flow and aquifer characteristics based on described stratigraphy and hydrogeology.
• Analyze land use impacts on groundwater resources based on the described land use and industry themes.
• Study geological history and basin evolution based on the described formations and fault structures.
• Support environmental management and planning based on integrated surface water, groundwater, and environment attributes.

Strengths

• Thematic grouping covers 11 distinct topics from geology to land use.
• Describes specific geological formations and structures like the Selwyn Fault and Sorrento Graben.
• Covers two distinct basins with shared and unique stratigraphic histories.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
