Australians are true professionals and their cricket board is very supportive of their players. And that is also one of the reasons why Australian players are some of the highest paid cricketers in the world. Indian players on the other hand are swimming in wads of cash, but they focus more on showoff rather than professionalism. And now coming to West Indies, I am not sure whether they can be competitive against the Australians. They performed poorly in the tour match against Cricket Australia XI (which didn't had any player with international experience).
Indian cricket is now tightly coupled with there film industry and that's why there is too much showoff in Indian cricket. They are too good at there home ground but average performer when playing outside.
West Indies playing good against Cricket Australia XI, on day West Indians lead by 356 runs and they have bowled out Cricket Australia XI in there first innings on just 175 runs. West Indies dont have the capability to beat Aussies but they must give there best here to make sure they don't lose by big margins.
