Australian Strategy hasn't been what Australian's Strategy should have been.Improper rotation of bowlers,Fielding error and most indisciplined bowling ( 22 wides in last match compared to 1 Wd and 2 Nb's of NZ though in this regard NZ are always disciplined.)
i think its just a phase and surely AUS are gng to bounce back.u cannot write off a GR8 team with just 5 lost games. and more over NZ is a good team and rt now they greatest form.
Had Australia lost 3-0 Zimbabwe,Kenya or Bangladesh i'd have seriously doubted their world Cup contention but it is beaten by a good Team .
Don't Write off Australia they are gonna bounce back
