BBC Test Match Special
It's a very Test match-looking line-up for Australia with their bowling attack.
It is time for the talking to stop and a new World Cup winner to be crowned.
Martin Guptill and Daryl Mitchell are out in the middle and it will be Mitchell Starc's left-armers to start.

Today caps the end of four weeks of entertraining cricket.
There have been some amazing catches, some scarcely believable shots and some expert bowling.
What has been your favourite moment?

The Australia national anthem is done. Glenn Maxwell had a big smile on his face while singing along.
Time for New Zealand's now.
It is almost time.
Both New Zealand - who beat England by five wickets - and Australia - who beat Pakistan by the same margin - were involved in tight, dramatic and entertaining semi-finals.
Remind yourself what happened...
Time for the important question of the day...
Who do you think will win?
Thumbs up for New Zealand. Thumbs down for Australia.
Please vote for who you THINK will win, rather than who you WANT to win (that could end up rather one-sided!).

The feeling of preparing for a final isn't something that many of us will be able to connect to.
How do you think you'd prepare?
Matt Henry spoke to West Indies' 2016 T20 World Cup hero Carlos Brathwaite and England's Ryan Sidebottom, Liam Plunkett and Alex Hartley - who have all played in and won finals in the last 11 years.
One took a trip to the zoo, another was sick at Lord's.
Here's how New Zealand made it to today.
They have been faultless since their first game defeat by Pakistan.
They are already World Test Champions and were runners-up in the 50-over World Cup. Can they win this and continue their unbelievable rise?
Here's how Australia made their way to their first T20 World Cup final.
Aside from that heavy defeat by England they have been pretty consistent.
Can they add this to their five 50-over World Cup crowns?

Both Australia and New Zealand suffered one defeat in the Super 12s but were impressive, particularly with the ball.
It could come down to who can be the most effective with the bat today...

Former England spinner on BBC Test Match Special
Kane Williamson will be devastated to miss out at the toss. But you have to move on. I have got every prediction wrong, virtually, in this tournament, so I'm going to say Australia are going to win!

Carlos Brathwaite
West Indies all-rounder on BBC Test Match Special
I've had a few punches of bats, helmets, walls when I've got out... I must not pack a powerful punch!
New Zealand captain Kane Williamson: "We would have done the same but it looks like a reasonable pitch. Who knows about the dew."
On Devon Conway's absence: "It is a real shame, one of those freak things. Maybe he will learn a bit of a lesson."
On the prospect of being T20 and Test world champions: "We don't want to look too far ahead. It is nice to be here in Dubai for a great occasion."
Australia captain Aaron Finch: "It looks a little bit drier than the one we played on last time. It might skip on with the new ball and hopefully it stays that way.
"The way we kept hanging in the contest against Pakistan was crucial for us. Adam Zampa has been superb for us. He's had a wonderful tournament and hopefully that continues tonight.
"When it's a new format, a new tournament, I don't think our record against New Zealand in knockout stages matters."
Australia are unchanged and New Zealand have brought Tim Seifert in for Devon Conway.
We'll bring you full teams shortly.
