Most of Australia's domestic oil refineries were built during the 1950s and 1960s, but high operating costs and the emergence of large refineries across Asia forced many to shut down over the past three decades.

Australia said on Tuesday it would consider building its first new oil refinery in more than 60 years, as war in the Middle East squeezes supplies from overseas and underscores the urgency to improve energy security.The federal government and the Western Australia state government will jointly spend A$4 million (US$2.8 million) on a feasibility study for the refinery, a government statement said.
