QGC, bought by Britain's BG Group in 2008, was first out of the blocks, getting approval for its $US15 billion Queensland Curtis LNG project and reaching a final investment decision in October 2010. Santos, in a joint venture with Petronas, approved its $US16 billion Gladstone LNG project the following January and Origin, together with ConocoPhillips and Sinopec, sanctioned the first train in its $US14 billion-plus Australia Pacific LNG project last December. Arrow Energy, owned by Shell and PetroChina, has yet to gain approvals or reach a final investment decision.
