Full, straight, on the stumps, and Warner can't get it away.
Wide again from Southee, and walloped once again for four!
Maybe don't bowl there...

Tim Southee will be disappointed with that. It was just in that area, with a little bit too much width.
David Warner cloths his first ball just short of the man at mid-wicket, before the next delivery is tonked and tonked nicely to the boundary for four.
Here's Tim Southee.

Trent Boult liked that a lot but he did come down the wicket a lot. It looked really good to me. Maybe it was just swinging down a little bit.
Target 173
Huge, huge appeal for lbw!
Trent Boult likes it. Boult really, really likes it. Kane Williamson weighs it up and then opts against it. It didn't feel out to me... going down leg.
Aaron Finch has a gallumphing swing and a miss at Trent Boult's penultimate delivery.
An inside edge from Warner dribbles away from the stumps, before he gets off the mark with a little flick for one.
Target 173
Short, and cracked to the fielder on the circle by David Warner.
We're off.
Trent Boult will bowl the first over for New Zealand.
Here. We. Go.

It's anyone's game.
Right. 173 for Australia to lift their first Men's T20 World Cup trophy.
Here come Aaron Finch and David Warner...
New Zealand's Glenn Phillips: "The way Noss (Williamson) took Starc down turned the match for us. It was just about going about each over as we saw necessary."

Former Australia bowler on BBC Test Match Special
New Zealand are my favourite sporting team around the world.
Cheers, Callum.
I think Australia might do this. But maybe that's because I've spent years having my tiny, cricket-loving heart broken by them.
Time for me to hand over.
Amy Lofthouse will take you through Australia's chase of 173.
Will it be Australia or New Zealand who win their first T20 World Cup?
A masterclass from the master.
Kane Williamson's innings will be remembered for a long, long time. It won't matter if he wins or losses this final.
He started slowly, making six from his 12 balls. He was on 21 from 22 when he was dropped by Josh Hazlewood on the boundary before being dismissed for 85 from 48 balls.
A real captain's knock.
In contrast Josh Hazlewood took 3-16 and bowled 18 dot balls in his four overs.
He only conceded runs from six balls... unbelievable.
