The problem is, there is simply no need for an Australian team. I can see why countries like Canada and the UK feel the need for one, but there are Australians with a wide range of skills and abilities all over the ProTour and ProConti shop. If you create a quasi-national team for them, it's just going to be a mess, because you'll have people with genuine GC aims, people who want to sprint, people who want to stage-hunt... and all of whom will be worthy talents that you want to take to the big races. And as we've learnt from Team Sky, if you try to do everything at once, you'll do everything, but only to a mediocre level.
The Aussie team would be much more interesting than the others, mind.
