Without Pat Cummins and Josh Hazlewood by his side, Mitchell Starc has full faith in Australia's replacement quicks stepping up for the first Test against England.
Starc, who famously opened the 2021-22 Ashes with a wicket from the first ball, will be the clear leader of Australia's bowling attack.
Brendan Doggett is set to make his Test debut after a superb 190-wicket Sheffield Shield career for Queensland and South Australia.
Doggett will join Starc and the prolific Scott Boland as Australia's quicks that will look to unsettle England at Perth Stadium on Friday.
Starc has played 100 Tests, while Boland is preparing for his 15th.
Australia will lose 147 Tests of experience with the absence of Cummins and Hazlewood.
"Sadly, injuries in fast bowling happen," Starc said on Wednesday.
"And it just so happened with two (key) men down, heading into the first Test.
"But good to see the depth in the squad.
"We know what Scotty Boland can do, 'Doggie's' coming off a hot streak at the moment, and 'Nes' (Queensland veteran Michael Neser) has been around for a while."
The series-opener will mark the first time since December, 2022, that Australia have started a Test without two of their 'Big Three' pacemen.
Hazlewood has endured numerous injury setbacks in recent years, but was entering the summer in superb form before his hamstring injury.
Unless there is another injury, Doggett might have to vacate his place for the second Test at the Gabba.
Cummins is nearing full fitness following a serious back injury, steaming in at full pace during an extended session in the Perth Stadium nets on Monday.
But there remains a chance Australia go with four quicks in Brisbane, as they did when playing a day-night Test against West Indies in July.
Starc quipped "do you want to get him in this week?", when asked if Cummins could return for the Gabba showdown.
"Probably understand why he doesn't train much, because when he does, he makes us all look silly," Starc said of Cummins.
"He was really sharp the other day.
"Sounds like he's pulling up pretty well, so all very positive."
Before Starc spoke, Australia's main training session was halted for almost 30 minutes due to lightning in the vicinity of the ground.
With the sun shining and no immediate rain expected, puzzled cricketers were ushered out of the nets back into the change rooms.
Australia had completed about 40 minutes of fielding drills on the ground, before heading to the nets to finish their session.
But before bowlers could properly warm up, all players, staff, and media were told to head indoors at about 10.30am local time.
Rules state if lightning is 5kms or less away from the ground, then outside activity needs to stop.
AFL games in Perth, and other cities, have previously had to be delayed because of possible storms.
But Australia were able to get back out to the nets, with adopted Tasmanian Jake Weatherald putting in another strong session as he presses his claims for a Test debut.
If selected, Weatherald will be Usman Khawaja's sixth opening partner since David Warner retired from Tests in January 2024.
With Marnus Labuschagne to be recalled, Australia are weighing up whether he should open, or bat in his preferred No.3 position.
