Australia has named its 15-player squad for their upcoming T20 World Cup defence with uncapped all-rounder Tim David included as the major bolter.

The Australians will look to defend their T20 title in the tournament that runs from October 16 to November 13 in Australia and New Zealand.

Globetrotting T20 star David is the major surprise in the squad and the only change from last year's group that lifted the world title in UAE, replacing spinner Mitchell Swepson.

Australia's squad includes the usual suspects such as David Warner, Glenn Maxwell, Steve Smith and vice-captain Pat Cummins. Mitch Marsh is selected despite a recent ankle concern.

Skipper Aaron Finch, 35, had been under some pressure to hold his spot but is named, with the group also to travel to face India in three T20 Internationals in September in preparation. Warner will be rested for the India tour with Cameron Green taking his place.

National Selection Panel chair of selectors George Bailey said: "This is a similar squad to that which became the first Australian’s men’s team to win a T20 World Cup who are now very excited about playing the tournament at home.

"Mitchell Swepson was unlucky to miss out based on conditions in the UAE at the last World Cup where we planned for tired, spinning wickets compared to what we would expect are good batting conditions along with the larger grounds in Australia.

"Tim continues to establish himself with some quality performances in leagues around the world, earning a place in the squad. He is a highly gifted, natural ball striker who will add extra batting depth to the group which has had a lot of success in T20 cricket.

"We expect him to play a similar role to that he has been playing in the past few years."

David, who previously represented the country of his birth Singapore in 14 T20Is in 2019 and 2020, has impressed in global T20 leagues including with the Mumbai Indians in the IPL, the Southern Brave in The Hundred and the Hobart Hurricanes in the Big Bash League.

The 26-year-old has amassed 1,874 runs at a strike rate of 168.4 in 86 T20 games over the past two years in a late-overs batting role, with part-time off-breaks.

David's strike rate of 216.28 in eight matches with the Mumbai Indians earlier this year was the highest by any player to have faced at least 50 balls in a single IPL season.

Josh Philippe, Ben McDermott, Sean Abbott, Jhye Richardson and Swepson were among the unlucky players to miss out on selection.

Australia faces India in the first of their three T20Is on September 20 in Mohali, with their first World Cup match against New Zealand in Sydney on October 22.
