Shocker from the 3rd Umpire / Ridiculous Umpiring

Okay, Bucknor was not his best in this match. But for god sake, not all of them can be like him? This shocker from the third umpire gives rise to lot many suspicions.
1. Whether Australia preplanned the fate of this match?
2. Whether there was a fear factor threatening the umpires?
3. Did Australia think winning by under table ensures their place as a well respected side?
Poor Australians, for them winning is everything!!!
