South-east Australian Fractured Rock Province Hydrogeological Inventory

A geospatial inventory of the South-east Australian Fractured Rock Province, compiled by Geoscience Australia. The dataset contains descriptive attributes grouped into themes including location, geology, hydrogeology, groundwater management, and land use. It was last updated on 2026-04-30.

Use Cases

• Model groundwater flow and recharge in fractured rock aquifers based on described fracture-dependent flow characteristics.
• Assess groundwater resource potential for irrigation or town supply based on described yield and usage statistics.
• Map geological and mineral deposit relationships within the Lachlan Orogen based on described lithological units.
• Analyze land use and environmental impacts on groundwater systems based on the described thematic attributes.

Strengths

• Covers a significant hydrogeological region, with fractured rock aquifers comprising about 40% of Australia's groundwater.
• Attributes are organized into 11 defined thematic groups, including hydrogeology, groundwater management, and environment.
• Provides context on groundwater yield, stating fractured systems account for 33% of bores but only 10% of total extraction.

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, explicitly excluding the New England, Thomson, and Delamerian Orogens.
