I think the AB's got lucky with that try but as what has been clearly pointed out Aussie could have been penalised at the same time. I also think the Aussies got lucky with one of their trys and the professional fouls commited saving an AB try so it more than evens out. And I also think if McCaw hadn't scored that try and it had been a penalty to AUS the AB's would still have won. They scored the winning try with 6-7min still on the clock, if they had needed to score another one it looked like they would have - if they needed to. Instead in that last 6-7min all they needed to do was close the game out and they did that easily.
