If both teams will look to chase in the final then who will bat first

( A joke)
It would be difficult to choose a winner at this stage as both the teams are in good form and both haven't won the T20 World cup. New Zealand is the one team which have the habit for making to the semi finals and finals most times but unable to hold on to the title. This may be their chance to win it.
It's not difficult, it's impossible now. We have seen the game of both the teams. Australia has done a great job against Pakistan. Although their bowling was a bit weak. New Zealand is a little forward in this way. Their batting and bowling is strong enough. However, it is not possible to predict which team will win in this match. Australia are more experienced than New Zealand in the final.
