Mitch Marsh blasted a record-breaking 31-ball half-century as Australia beat New Zealand by eight wickets to win their first T20 World Cup title.
Kane Williamson made a majestic 85 from only 48 balls after being dropped by Josh Hazlewood on 21 as New Zealand posted 172-4, after being put in by Aaron Finch in the trans-Tasman showdown at Dubai International Stadium on Sunday.
That was the joint-highest score in a T20 World Cup final, with Marlon Samuels having been 15 short of a hundred in West Indies' victory over England five years ago. It was also the fastest half-century ever scored in the final of the competition for a short time, until Marsh's heroics.
Williamson reached his fifty from 32 deliveries as Mitchell Starc endured a nightmare, the left-arm quick's four wicketless overs going for 60. The outstanding Hazlewood was the pick of the Australia bowlers with brilliant figures of 3-16.
Australia produced another magnificent run chase on the back of a stunning semi-final win over Pakistan, Warner and Marsh putting on 92 for the second wicket.
Warner made a superb 53 from 38 balls and Marsh was unbeaten on 77 from 50 deliveries as Australia were crowned champions with seven deliveries to spare.
Marsh raced away to his half-century, taking spinner Ish Sodhi (0-40 in three overs) apart as Trent Boult's brilliant figures of 2-18 were in vain.
All-rounder Marsh had not fully realised his potential in an injury-hit career but showed he can be a world-class performer on a historic Sunday night for Australia as New Zealand endured heartbreak in their first T20 World Cup final.
World-class Williamson the man for the big occasion
New Zealand were only 32-1 at the end of the powerplay, with Daryl Mitchell caught behind off Hazlewood, but Williamson shifted through the gears in a masterful innings with sweet timing and power.
The skipper was put down by Hazlewood in the deep in the 11th over from the expensive Starc before hitting Maxwell for back-to-back sixes to reach his half-century - the first of those with one hand coming off the bat as he hoisted the ball into the stand.
Martin Guptill (28) fell to star spinner Adam Zampa (1-26) after being dropped by Matthew Wade on 10, but the boundaries continued to flow for Williamson, who hit three sixes and 10 fours before holing out off Hazlewood.
Marsh and Warner make light work of run chase
Boult got an early breakthrough when he sent Finch on his way, but Warner and Marsh swung the game in Australia's favour with clean striking and great running between the wickets.
Marsh struck the first ball he faced from Adam Milne for six, while Warner looked increasingly ominous, taking a liking to the spin of Sodhi and hitting Jimmy Neesham for a huge six to reach a 34-ball half-century.
The excellent Boult returned to clean up Warner and the left-arm paceman dropped a tough chance to dismiss Marsh when Australia were almost home.
Glenn Maxwell (28 not out) struck Tim Southee for four to win it, with Marsh still unbeaten after striking four sixes and another six boundaries in a stunning innings.
