Hydrogeological Inventory for South-east Australian Fractured Rock Provinces

South-east Australian Fractured Rock Province hydrogeological inventory provides descriptive attribute information for areas bounded by spatial groundwater features. The dataset groups topics into themes including location, geology, hydrogeology, groundwater management, and land use. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Analyze groundwater yield and extraction rates using data on bore contributions and aquifer storage mechanisms.
• Model groundwater flow direction by examining data on fracture orientation and hydraulic head distribution.
• Assess land use and industry types in relation to hydrogeological features for environmental planning.
• Study recharge characteristics in localized fractured rock aquifers using physical geography and surface water data.
• Correlate lithological units and mineral deposit types, like orogenic gold or porphyry Au-Cu, with groundwater management data.

Strengths

• Covers a significant region where fractured rock aquifers store about 40% of Australia's groundwater.
• Groups descriptive data into 11 structured themes including geology, hydrogeology, and land use.
• Includes data on a region accounting for approximately 33% of all bores in Australia.

Limitations

• Spatial coverage is limited, excluding the New England, Thomson, and Delamerian Orogens.
• Primary data format is PDF, which may hinder direct computational analysis.
• Specific row counts, column details, and sample data are unavailable for quality assessment.
