Australia were crowned T20 World Cup champions for the first time as twin fifties from David Warner and Mitchell Marsh consigned New Zealand to another runners-up finish on the global stage.

The Black Caps were seeking a maiden T20 crown themselves to add to their World Test Championship triumph and were given hope by Kane Williamson's atypically belligerent 85 from 48 balls following a ponderous start batting first in Dubai.

New Zealand’s 172 for four represented the highest score in a T20 final but it was not enough as they lost by eight wickets, with Warner’s 53 off 38 deliveries and Marsh’s 77 not out off 50 deliveries getting Australia home.

Unlike the 2016 showpiece, when the West Indies beat England thanks to four consecutive sixes by Carlos Brathwaite in the last over, there was no grandstand finish as Australia overhauled their target with seven balls to spare.

Australia head coach Justin Langer described Australia's victory as "a very special moment for everyone".

He added on Sky Sports: "Everyone that wins a World Cup says it’s hard to process, it’s hard to put it into words, but this is such a special group of people.

"I know every coach and every captain says the same thing, but we’ve got some amazing cricketers here.

"We have not had the chance to play with each other for different reasons over the last 12 months, so when we all got back together it was like a reunion."

Warner put his good form down to "going back to basics".

He said: "We had two practice matches and didn't spend much time in the middle, but for me it was about going back to basics and getting on some hard synthetic wickets to train.

"These guys are an absolute great bunch of guys, great support staff, great team and great support around the world, especially at home.

"I’m always pumped, we just wanted to put on a great spectacle for everyone here at the venue and we were able to deliver it today. There was a little bit of nerves around with a good total on the board in a final but it was great to see the guys deliver."
