Umm, before this topic takes a turn into a backwater could it just be pointed out that $600M is hardly a war chest to do anything. That would be $350M for a Business Class sleeper seat makeover [that GD clearly does not want, but is being forced into by decisions made by the 'friendly' people at BA] , $100M for knocking over the hangar next to Sydney Domestic and extending the terminal to fit in some A330s and $150M in spare change, which does not even buy half of one of the 747-400ERs on order, let alone anything else.
A bit premature to be talking about O/S opportunities, is it not? [Unless you are trying to put pressure on some Kiwis, I guess, by inferring that you could just walk].
