Who will give the Australia most tough time in World Cup

ithink it is usually the kiwis and england teams which give australia a really tough time.i think india can also be a tough team to play against the australia.

i think only south africa loooks the only team that can giv ethem run for there money ,i think they are the best team in da world but south arfrica can give them an hard fight any given day ,the other two teams i think are dark horse like Kiwis and west indies who on there day can destroy anyone

well this is really a toughie.The champions seem to be on a winning spree and there isnt any team as of now to scare Australia.India unprdictable as always might do some damage f the players pick up their magic.but that is not bound to happen as of now.i would say that South Africa will posea threat for the champions.They seem to be in good form when compared to most other teams.
