Its Good that the New coach of Australian comes Forward to work on the lacking area. But only time will tell how far will he suceed in his Effort.
We all know the behaviour of Australians esp. McGrath, Slater, Including Captain Himself and some more who are always in sledging and abusing the opponent player and misbhaviour with officials too (Ex. Slater and Pointing behaviour in Steve waugh's Captaincy tour to India).
Lets Hope now there will b a reform in Australian side on their behaviour too.
