Australia need to be challenged, NZ didn't do this in Perth! They played horribly. If Australia are not threatened they will look unbeatable and the class players will dominate. But, if another side comes out and throws the ball around a bit and pulls of a few big defensive sets then Australia might begin to show their age and relative inexperience. I think that both England and NZ are capable of doing this but it's just not what usually happens because they are both too inconsistent. In short both England and NZ have to play at their best to win. The hope is that this 4 nations is the turning point where they both begin to play consistently at that level and both knock off Aus. To be honest though.. don't think it will actually happen even though thats what i'm cheering for. On England and Bennett, If he can get them improving every game they play from now till the world cup.. It's there that they will be a real threat!!
