Swingpass,
I hate to say it, but if the situation is as dire as some people think it is, perhaps the right decision was made to go to Perth. At least they are surviving, apparently. Incidentally, the reason that the Force bid was accepted was that it was far more compelling than the Victorian bid.
Presumably the Rebels franchise was granted on the basis of some sort of expectation of success. It would be worthwhile knowing where the shortcomings are. If the problem is just that the original financial backer wants out, but all the indicators are good, then maybe the ARU should step in. However, for all the "free kicks" that the NRL have had, their franchise still loses money, and their crowd numbers are not much better than the Rebels.
The NRL franchise will survive because apparently the ratings are okay in Melbourne.
The Rebels will not survive on charity from the ARU, it is up to the rugby community in Victoria, and maybe the State Government to support them (note that the Queensland Government propped up the Reds for a while, with Queensland Rail taking the main sponsorship for a couple of the dark years).
