Is Australian team also dependent on few players now?

You have hit the nail right on its head. The era has gone long ago. It was gone with the likes of Langer, McGrath, Hayden, Glichrist and the likes retiring. Only the experienced of the lot is Ponting, I think and along with him is Mike Husey. Hopes is good upto some extent and so is Bracken, Hogg and Hodge. But these players don't seem to have cemented their place in the side. They are always fluctuating in and out and so don't seem to perform well. But anyways, the teams like India and South Africa are fast emerging for the challenge for the Aussies and they will find it absolutely difficult to continue to remain at the top.

yes you are right.they are looking like an ordinary team only.. not in the best form..but captain ponting always playing well..
