Kane Williamson is excited by the prospect of New Zealand pulling off a dream double when they face Australia in the T20 World Cup final on Sunday.

The Black Caps beat India to win the inaugural World Test Championship in June and they will contest a third consecutive ICC final at Dubai International Stadium this weekend.

New Zealand had never reached a T20 World Cup final before defeating England with a magnificent run chase on Wednesday and captain Williamson is urging his side to rise to the occasion when they do battle with their trans-Tasman rivals.

He said in a press conference on Saturday: "It'd be some achievement [to do the double],

"But where it stands at the moment is there's a game of cricket to play and for us it's focusing on that and focusing on our cricket and looking to go out there and implement the things that are important to us.

"These sort of events are of focus in the calendar and it's a really exciting opportunity to be here now and looking forward to the match tomorrow."

Australia also chased down a big total to upset Pakistan and moved into their second World Cup final in the shortest format, having lost to England in 2010.

Skipper Aaron Finch says Australia always had the belief they could defy the odds and go all the way to the final.

He said: "It wasn't unexpected. We came here with a clear plan to try and win this tournament. We always felt that we have the depth and quality to do that.

"A lot of people had written us off from the start, so it has been really impressive the way we have gone about our business. Everyone has prepared really well and had match-defining performances at some point, the guys are up and about for tomorrow."

New Zealand and Australia head-to-head in 2021

Conway blow hands Seifert unexpected chance

It was a memorable day for New Zealand when they knocked England out in midweek, but one of mixed emotions for Devon Conway.

The wicketkeeper-batsman made 46 before he was stumped giving Liam Livingstone the charge and he reacted by punching his bat, inflicting further pain on himself by breaking his hand.

Conway will miss the final as a result of that furious response to his dismissal, so Tim Seifert comes into the side.

Seifert has big shoes to fill, as Conway has been a revelation in his short international career so far. The left-hander scored 129 runs at an average of 32.25 in his first T20 World Cup.

Stand-in keeper Seifert made only eight in his only appearance of this tournament against Pakistan after coming in at seven in the order. He averages 24.24 in 33 T20I knocks.

David Warner

Warner silencing the doubters

Questions were raised about David Warner's place in the Australia side ahead of the tournament after he was dropped by Sunrisers Hyderabad during the Indian Premier League.

The opener has shown his class in the United Arab Emirates, making 236 runs from six innings at an average of 47.20 

Only Matthew Hayden (265 in 2007) and Shane Watson (249 in 2012) have scored more for Australia in a single edition of a T20 World Cup.

Warner’s 35 boundaries in the campaign (28 fours, 7 sixes) are the joint-most by any player in the tournament (level with Mohammad Rizwan and Jos Buttler).

Australia showed the strength of their batting line-up in a five-wicket win over a Pakistan side that had won every match to cruise into the last four, Matthew Wade blasting a brilliant 41 not out off 17 balls and Marcus Stoinis making an unbeaten 40 after Warner's rapid 49.
