In my recent post on coal seam gas (CSG) I noted that BG's bid for Origin Energy was the event that kick-started the boom in interest in Australian CSG producers.

BG's bid for Origin eventually failed (with ConocoPhilips instead buying a share of Origin's CSG assets), but they have now returned to the fray - this time with a $5 billion bid for QGC (Queensland Gas Company).

BG already owns 9 per cent of QGC (and 20 per cent of QGC's CSG reserves) and is keen to secure supplies for planned LNG export plant at Gladstone.
