Petroleum Potential of Australia's Central Eastern Margin, Preliminary Assessment

A preliminary assessment report on petroleum potential for Australia's east coast, from the New South Wales-Victoria border to the southern boundary of the Great Barrier Reef Marine Park. The report was published by Geoscience Australia and last updated on 2026-03-25. It covers a region with sparse exploration history, known sedimentary basins, and areas where exploration is prohibited.

Use Cases

• Identify prospective sedimentary basins for hydrocarbon exploration based on the described geological framework.
• Assess regional exploration risk by mapping areas with known data versus virtually unknown geology.
• Model basin evolution and petroleum systems based on the mention of graben features associated with Tasman Sea rifting.
• Support policy and permit planning by incorporating the defined exclusion zone of the Great Barrier Reef Marine Park.

Strengths

• Report provides a defined spatial coverage from a specific southern border to a northern boundary.
• Identifies at least four specific sedimentary basins with offshore extensions.
• Explicitly states areas where petroleum exploration is prohibited, clarifying scope.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a sparsely explored region.
