Pat Cummins said it was "awesome to be able to join the club" after he took a hat-trick in Australia's T20 World Cup win over Bangladesh.

Cummins starred with the ball while David Warner was key with the back as Australia maintained their perfect record in the tournament to start their Super 8s campaign with a 28-run victory.

It was a rain-impacted encounter in Antigua on Thursday, with Australia ultimately prevailing on the Duckworth-Lewis-Stern method, with the weather having ended play when they were on 100-2 while chasing a target of 141.

Cummins' three wickets came across the 18th and 20th overs of Bangladesh's innings, with Towhid Hridoy (40) his final wicket.

"At the end of the over, I saw it come up on the screen and I totally forgot about [the hat-trick]," Cummins said.

"I've taken a few in junior cricket but never for Australia. It's pretty awesome to be able to join the club."

Warner then took control with the bat, striking an unbeaten 53 from 35 deliveries to ensure Australia were well on course for victory before the weather closed in.

Australia captain Mitchell Marsh added: "A really solid bowling performance, everyone chipped in.

"We've always spoken about having 15 guys who can take us deep in this World Cup and we will pick teams on conditions."

Data Debrief: Magnificent seventh

Cummins became just the seventh player to take a hat-trick of wickets at the men's T20 World Cup and the first Australia player since Brett Lee took 3-27 in 2007.

Coincidentally, Lee's hat-trick also came against Bangladesh.
