Offshore gas

Supporting offshore gas exploration with geoscience

Natural gas has been extracted in waters off Victoria's coast for many decades and is a vital part of the state's energy supply network. Future supply is dependent on new gas discoveries.

To stimulate commercial exploration for natural gas resources, the Victorian Government offered five new offshore acreage areas in the Otway Basin for tender in May 2018. Following an assessment of applicant bids by the Earth Resources Regulator, permits to explore two of these areas were granted by the Minister for Resources in July 2020.

To support this investment attraction activity, the Geological Survey of Victoria created key geological datasets from existing information. In addition, the Otway Basin airborne gravity survey of 16,000 square kilometres of south west Victoria (undertaken in the second half of 2018) included both offshore and onshore components.  The data acquired has connected together the geological modelling of the offshore and onshore parts of the basin at a new granular level.
