It is no fault of the australian team if the decisions of the umpires went in their favor. No I dont think that the australians would have bribed the umpires. I guess this kind of bad umpiring decisons happen in Cricket all the time and it becomes a much bigger issue when records are broken due to the bad umpiring decisions. Anyways it cannot be expected from the umpires not to commit even one mistake.

I'd call it luck that australia won. The title of this thread should have been Bad Umpiring Decisions and the criticism should have been directed at the umpires not at the australians. After all umpires made the wrong decisions not the australian team. I believe everytime wants to win and specially in international matches winning becomes much more important.
The big question here is had the bad umpiring decisions gone in favor of India and against australia, would india have protested and tried to rectify the blunders committed by the umpires???
