The Gorgon gas project is a natural gas project in Western Australia, involving the development of the Greater Gorgon gas fields, subsea gas-gathering infrastructure, and a liquefied natural gas (LNG) plant on Barrow Island. The project also includes a domestic gas component. It is currently under construction and once completed, will become Australia's fourth LNG export development.

Other fields in the group lie to the north, such as Jansz-Io, which covers an area of 2,000 square kilometres (770 sq mi), in a water depth of 1,300 metres (4,300 ft).
