South-east Australian Fractured Rock Province Hydrogeological Inventory

Fractured rock aquifers store about 40% of Australia's groundwater and account for approximately 33% of all bores. This dataset from Geoscience Australia provides a descriptive hydrogeological inventory for the South-east Australian Fractured Rock Province, grouped into themes including location, geology, hydrogeology, and land use. The data was last updated on 2026-04-20.

Use Cases

• Modeling groundwater flow and recharge in fractured rock systems based on fracture orientation and distribution described in the dataset.
• Assessing groundwater resource potential for irrigation or town supplies based on the hydrogeological and groundwater management attributes.
• Correlating mineral deposit types with specific lithological units and geological structures within the Lachlan Orogen region.
• Analyzing land use and environmental impacts on groundwater quality and availability in fractured rock aquifers.

Strengths

• Covers a region where fractured rock aquifers comprise about 40% of Australia's groundwater.
• Descriptive attributes are organized into 11 specific thematic groups, including hydrogeology and groundwater management.
• Includes information on a significant geological region, the Lachlan Orogen, which hosts diverse 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).
