Compare the records of the two. I'd be willing to bet that Australia get at least 5 times as many decisions given to them than any other side. It's the Over appealing, early celebrations (hence Lee's fine in the last test), charging of the Umpires and general aggression that I find disgraceful. Sure other teams appeal and get decisions given for them, but when they appeal and it's not out, they forget about it. Australia don't. It's either Ponting marching up to the Umpire demanding answers or Warne and his 'Oh, we're obviously not playing LBW's today' that is the problem and is why Australia are the most hated team on the Planet. Sure mistakes happen, but Australia force the Umpires into making these mistakes with their aggression.
Incidently, McGrath called England cheats when he was given out, can you imagine the reaction the media would have if England did the same? But wait, I'm forgetting, most teams in the World wouldn't do that as they play in the right spirit.
Australia best in the World, if they can't do it on the pitch they open their mouths and point their fingers to get their own way. Or throw a tantrum of course. Ricky Ponting Run Out (Pratt) Evidence.
