South-east Australian Fractured Rock Province Hydrogeological Inventory

A geospatial inventory of hydrogeological attributes for fractured rock aquifers in south-east Australia. The dataset groups descriptive information into themes including location, geology, hydrogeology, groundwater management, and land use. It is published by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Modeling groundwater flow and recharge in fractured rock systems based on described fracture-dependent flow characteristics.
• Assessing groundwater resource potential for irrigation or town supplies based on the described yield and usage patterns.
• Correlating lithological units and mineral deposits with hydrogeological properties based on the described geology of the Lachlan Orogen.
• Informing land-use and environmental management policies based on integrated themes covering surface water, groundwater, and industry types.

Strengths

• Covers a significant region, as fractured rock aquifers comprise about 40% of Australia's groundwater.
• Integrates multiple thematic areas (11 listed themes) for a multi-faceted environmental assessment.
• Provides context on regional geology, noting the Lachlan Orogen contains diverse lithological units and mineral deposits.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The study scope is limited, as it does not include additional Orogens in the east (New England) and west (Thomson and Delamerian).
