Sydney Basin Hydrogeological Inventory with Geology and Groundwater Attributes

The Sydney Basin dataset contains descriptive attribute information for spatial groundwater features in the Sydney Basin region of Australia. It was published by the Australian Ocean Data Network and last updated on April 10, 2026. Descriptive topics are grouped into themes including location, demographics, physical geography, surface water, geology, hydrogeology, groundwater management, and land use.

Use Cases

• Model groundwater flow and management based on hydrogeological attributes.
• Analyze the relationship between coal deposits and geological strata based on described coal measures and formations.
• Study basin evolution and tectonic history based on described stratigraphic succession and tectonic events.
• Assess land use and environmental impacts on groundwater resources based on grouped thematic attributes.

Strengths

• Thematic grouping covers 11 distinct topics including geology, hydrogeology, and land use.
• Provides detailed geological context, including stratigraphic periods from Late Carboniferous to Middle Triassic and maximum burial depths of 2,000 to 3,000 metres.

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 hinder direct machine-readability and analysis.
