I am not an Australian, so take this for what it's worth: AWE's onshore gas is a strategic asset for the country of Australia. If I were in the Aussie government, I think I would look hard at finding a way to stop the deal. It's not in the strategic interests of Australia to have such a large amount of gas priced by a foreign power, or potentially diverted out of Australia.
That said, as a long-suffering AWE shareholder, it's nice to see the price jump higher for a while. The best outcome here would be a bid from an Aussie firm and a bidding war. At this point, I think I would take 90 cents, even though I feel the potential is for north of $1.10, once they get closer to production.
