Otway Basin Hydrogeological Inventory with 11 Thematic Groups

An Australian Ocean Data Network dataset updated on 2026-04-10, providing descriptive attribute information for spatial groundwater features in the Otway Basin. The dataset groups information into 11 themes including location, geology, hydrogeology, groundwater management, and land use. The basin covers approximately 150,000 square kilometres, stretching about 500 km from South Australia to Victoria and Tasmania.

Use Cases

• Model groundwater flow based on the described fault systems and aquifer connectivity.
• Assess groundwater management and use based on the thematic administrative and environmental attributes.
• Study sedimentary basin evolution for hydrocarbon prospectivity based on the described Cretaceous and Cenozoic rock sequences.
• Analyze land use and industry impacts on groundwater resources based on the described thematic groups.

Strengths

• Covers a large geographic area of approximately 150,000 square kilometres.
• Information is organized into 11 distinct thematic groups for structured analysis.
• Describes a complex geological history including rifting, subsidence, and multiple sedimentary cycles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided in PDF format, which may hinder direct computational analysis.
• Row count is unknown, which may limit suitability assessment.
