The hosts handed a debut to 19-year-old Western Australian fast bowler Mahli Beardman, while England captain Harry Brook admitted his side would also have bowled first had they won the toss.

"We're not disappointed. We'd have had a bowl if we'd have won the toss, but look, you've got to do both aspects of the game at some point, so we'll take it on," Brook said.

Marsh said the pitch looked good and was unlikely to change, adding that Australia prefer to chase and hope to apply early pressure with the ball.

The Australian skipper described Beardman's debut as exciting for the young quick, noting there is no better place for a West Australian to start his international career.

Marsh emphasised the importance of winning the first match of the summer, acknowledging his side is relatively young and inexperienced but full of energy.

Brook said England had enjoyed a strong preparation, including training at the WACA and a practice match, which they rarely get in white-ball cricket.

The England captain confirmed his team would field four fast bowlers alongside spinner Liam Dawson, with Adil Rashid left out of the XI.

Australia's line-up comprises Travis Head, Marsh, Cooper Connolly, Matt Renshaw, Josh Inglis, Cameron Green, Jack Edwards, Xavier Bartlett, Adam Zampa, Spencer Johnson and Beardman.

England selected Ben Duckett, Tom Banton, Joe Root, Brook, Jordan Cox, Sam Curran, Will Jacks, Liam Dawson, Jamie Overton, Gus Atkinson and Jofra Archer.

England reached 25 without loss after five overs, with Duckett and Banton negotiating the new ball from Bartlett and Johnson.

The series moves to Adelaide for the second ODI on Sunday and Hobart for the third on Wednesday, before a five-match Twenty20 series begins on Friday.

England are looking to rebound from a disappointing tri-series performance in Pakistan last month, where they failed to reach the final.

Australia's youthful side features several players with limited international experience, but Marsh believes the energy in the group can compensate.

The second ODI at Adelaide Oval on Sunday will give both teams a quick chance to adjust after the series opener.
