Geoscience Australia Borehole Database: Onshore and Offshore Drilling Records

Geoscience Australia's BOREHOLE database contains header and directional survey data from boreholes drilled by the agency and its predecessors, resource exploration in Commonwealth offshore jurisdictions, and selected onshore mineral, groundwater, geothermal, and seismic boreholes. The data is sourced from various Australian state, territory, and Commonwealth regulatory authorities for research purposes. The dataset was last updated on 2026-04-28.

Use Cases

• Mapping subsurface geology based on borehole location and survey data.
• Analyzing trends in mineral exploration activity based on borehole source types.
• Modeling groundwater aquifers using data from selected groundwater boreholes.
• Studying geothermal potential based on geothermal borehole records.

Strengths

• Includes data from multiple authoritative sources, including state and Commonwealth regulatory bodies.
• Covers diverse borehole types: mineral exploration, groundwater, geothermal, seismic, and research.
• Last update timestamp is precisely recorded as 2026-04-28 15:19:51.282683.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Geoscience Australia notes it is not the authoritative custodian for all data; original sources should be consulted.
