South East Gas Study

The Offshore South East Australia Future Gas Supply Study, released on 24 November 2017, found offshore south east Australia basins have sufficient known gas resources to provide gas to the local market for the next 20 years, providing there is ongoing investment in exploration and development.

The Australian Government commissioned the study into offshore gas basins in Southern Australia, as part of the A$90 million investment in domestic gas security and supply. The study:

  • Provides an understanding of the volumes of gas available within the offshore south east Australian basins for potential future input into the east coast domestic gas market.
  • Identifies short and long term opportunities to maximise sustainable gas recovery from the offshore south east Australian basins.


The accessibility and price of gas in the eastern Australian gas market have been identified as key risks for Australian business competitiveness and cost of living pressures. Predicted supply shortfalls by the end of the decade, combined with other factors including linking to international export markets, ageing infrastructure, state and territory bans, are resulting in a higher new ‘normal’ gas price and constrained availability. The study was prepared by the Department of Industry, Innovation and Science, which includes the National Offshore Petroleum Titles Administrator (NOPTA), with contributions from Geoscience Australia, and in consultation with the Victorian, South Australian and Tasmanian state governments.
