I'll be more than happy if Australia continue to pick Beer as their back up spinner as they have for the WI tour! In all honesty from an an Englishman I think the last Ashes series was a the nadir for Aussie cricket, they had been on top of the world for so long that they fell into a complacency and expected everything to carry on as usual, it didn't. The overhaul at the top level should go a long way to making sure this doesn't happen again.
In Clarke I think they have found the ideal Captain and have moved away from the stereotypical Aussie Captain ie Taylor, Waugh, Punter (you wouldn't see any of those guys putting their arms around someone like Johnson when he has a bad day at the office)! Punter looks to be getting back to his best without the added pressure of being Captain, which can only be good for a team in transition.
It's also good to see that they are taking a chance on some younger quicks, Cummins, Starc et al. The emergence of Warner as a Test batsman is great to see, and something that maybe the Indians can learn from, you don't need to score at a rate of 10 an over in Tests and you need to change your game from the shorter formats to adjust to this. I can't believe that there isn't a better keeper in Australia than Haddin, frankly his chat in the India series would of been fine if he'd been able to back it up with a couple of performances, he couldn't, and to be honest had it been Prior I'd of been embarrassed!
There is improvement there, and as we all know you can't keep the Aussies down in any sport for long, but rebuilding takes time and they need to make sure they don't make any rash decisions. The whitewash of an ageing (and in my humble opinion overrated) Indian team that don't like playing on anything but the flatest decks aside a 1-1 draw at home to NZ and some pretty poor moments against South Africa shows there is still some way to go.
