The Wallabies midfielder Pat McCabe says a rare win over the All Blacks in this weekend's tri nations decider, will boost confidence but doubts it'll give them a psychological edge ahead of the World Cup.
McCabe says self-belief was high ahead of Saturday night's test in Brisbane, where Australia hope to break a 10-year Tri-Nations title drought.
McCabe says the Wallabies learnt a lot from the 30-14 loss to the All Blacks at Eden Park earlier this month, particularly the need to be much more physical in the early stages of the match.
