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 the Australian Ocean Data Network contains descriptive attribute information for the South-east Australian Fractured Rock Province, grouped into themes including location, geology, hydrogeology, and groundwater management. The data was last updated on 2026-04-28.

Use Cases

• Assessing groundwater availability for irrigation and town supplies based on hydrogeological attributes.
• Modeling groundwater flow direction influenced by fracture orientation mentioned in the description.
• Analyzing the relationship between lithological units and mineral deposits in the Lachlan Orogen region.
• Evaluating localized recharge patterns in fractured rock aquifers.

Strengths

• Covers a significant region where fractured rock systems comprise about 40% of Australia's groundwater.
• Descriptive information is organized into 11 thematic groups, including hydrogeology and groundwater management.
• Includes data on the Lachlan Orogen, a region with 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 excludes additional Orogens in the east (New England) and west (Thomson and Delamerian).
