This debacle has highlighted the need for the government to regulate the minimum requirements that Qantas must always provide in regards to availability of aircraft to ensure continuity of travel for the Australian public.
The reality of what will happen is Jetstar and Virgin will grow off the back of what happend. As Qantas proper gets smaller and its fate is less inclined to cause a meltdown then the imputes to save it will purely be emotional. At that point they will make a half assed attempt to save it, but it will be to late, they will take off all restraints and let the cards lay where they fall.
Western Governments are not in the airline industry any more and nationalization would have far greater implications to the stockmarket than you would like. It is not going to happen, far bigger unions and industry's have been moaning about offshoring for years, and see where that has got them.
