T20 WC Final: Good thing to play IPL in UAE, helped Hazlewood adapt quickly, says Australia pacer Cummins
In the summit clash, Australia outclassed New Zealand by eight wickets with seven balls to spare while chasing a target of 173.
Williamson provided much need fire to the New Zealand batting order which otherwise had an off day.
The Australian team has come into the T20 World Cup three successive series it played this year in the lead-up to the tournament.

Neesham had his reasons to not move an inch in the dugout after scoring a momentum-changing 27 off 11 balls in the first semifinal.
