Pat Cummins, Mitchell Starc, Steve Smith and David Warner produced no performances of note ahead of the Twenty20 against Sri Lanka in Adelaide on Sunday - Australia's first international of the summer.

Warner was out for just four, caught and bowled by Riley Meredith. It followed a duck and 15 not out in the Sheffield Shield match against the Tigers and his disastrous tour of England.

Smith reached nine when he flashed a shot from Meredith into the hands of square leg fielder Simon Milenko.

Cummins and Starc went wicketless at North Sydney Oval although the former was making his first start for the season, the latter coming off the back of an extraordinary ten-wicket Sheffield Shield haul on the weekend.

Instead it was Tasmania's only inclusion for the T20 internationals, Ben McDermott, who set up the win with a dynamic 58 off 61 balls at the top of the order.

Tasmania eventually eased past NSW's 237 off 43.1 overs, reaching 4-239 with 29 balls to spare.

George Bailey helped the Tasmanians home with a polished 67, while Jordan Silk was equally composed with his unbeaten 59.

Josh Hazlewood was the only star to shine for NSW with the paceman barely missing a beat in his first outing since the tour of England in returning 3-47.

There was, however, little joy for Cummins (0-62), Starc (0-49) and spinner Nathan Lyon (1-48).

Despite the lack of wickets, McDermott said the Australian pace trio impressed.

"It was very tough batting against those guys, with Patty (Cummins) bowling pretty quick into the breeze, and Starcy the same from the other end," he said.

McDermott was struck on the shoulder by Cummins and was briefly headed back to the pavilion on 29, only to be called back for a no-ball from the Australian vice-captain.

Last year's cup player of the season has now hit three half centuries and one century in five matches at an average of 69.5.

McDermott, the son of former Test quick Craig McDermott, played eight T20 internationals in 2018.

"I'm pretty happy with how I'm hitting the ball in white ball cricket, and it is nice to feel in good form coming into the Australian side," McDermott said.

The win takes Tasmania off the bottom of the standings and they retain a slim chance of a top-two finish.

NSW's campaign, however, is effectively over with the Blues now needing two massive bonus-point wins to stay in contention.

Rookie Tasmanian medium-paced Nathan Ellis was named player of the match for his 5-38.
