Australian Onshore and Offshore Borehole Geological Records

Geoscience Australia's Boreholes database provides borehole header, directional survey, and lithostratigraphic data. The service aggregates records from government and private entities, including all Commonwealth offshore marine jurisdictions and a selection of onshore sites. It was last updated in April 2026 and conforms to the GeoSciML v4.1 data standard.

Use Cases

• Model subsurface lithostratigraphy using borehole lithology and stratigraphic data.
• Analyze borehole trajectories and spatial distribution with directional survey and header location fields.
• Correlate geological formations across regions using standardized GeoSciML v4.1 lithostratigraphic observations.
• Identify drilling activity history and status from borehole header metadata sourced from regulatory authorities.

Strengths

• Conforms to the GeoSciML v4.1 data transfer standard for interoperability.
• Includes all boreholes drilled in Australian Commonwealth offshore marine jurisdictions.
• Data dictionary and status vocabulary are provided as linked PDF documents.

Limitations

• Specific row count, column count, and temporal coverage of the records are not provided.
• Data is aggregated from multiple external custodians, potentially introducing format inconsistencies.
• Geoscience Australia is not the authoritative source for all records, requiring consultation with original custodians.
