Going into a big tournament with a couple of wins under your belt does give you some confidence but i think it's about testing the water.
Exactly this is a big tournament. And both teams are good in performance. In this tournament these two teams have two series ODI and T20. So they will play 3 ODI's and 5 T20 matches. At this time this little bit difficult to say who will win because both are good teams. So let's see and enjoy. And I hope Australia will perform well and will win both of the series.
