Scott Boland has been cleared to play the fifth Ashes Test in Hobart, where England have opted to bowl after making five changes to their XI for the series finale.
Jonny Bairstow, who suffered a thumb injury while helping the tourists salvage a draw in Sydney, has joined wicketkeeper Jos Buttler (broken finger) in being an enforced omission for the day-night Test.
England have run out of patience with out-of-form opener Haseeb Hameed, while Jimmy Anderson and Jack Leach have also been omitted.
Ben Stokes, who suffered a side strain at the SCG, will push through the pain barrier and play.
"It is frustrating (that injuries have forced more changes). It's something we've had to battle throughout the whole pandemic," Joe Root said after winning the toss.
"Something we have tried to manage as best we can.
"We have five days hard cricket where we can give a good account of ourselves. We have to take the opportunity."
The match was slated to start at 3pm AEDT, with umpires upbeat it will get underway at 3.30pm after a brief rain delay.
Rory Burns, who was axed himself in Melbourne by England's selectors after a terrible start to series, has been recalled to open alongside Zak Crawley.
Ollie Pope will bat at No.6 in the absence of Bairstow, while Sam Billings will take the gloves on debut after being presented with his cap by veteran paceman Anderson.
Fast bowlers Chris Woakes and Ollie Robinson have replaced Anderson and left-arm spinner Leach in a rejigged attack.
Pat Cummins noted at the toss that Australia "were probably going to have a bowl today".
"Not too upset," Cummins added.
Boland, who is nursing sore ribs after a bowling mishap at the SCG, has passed his fitness test.
Australia made one change for the match, recalling Travis Head' at the expense of opener Marcus Harris.
Australia XI: David Warner, Usman Khawaja, Marnus Labuschagne, Steve Smith, Travis Head, Cameron Green, Alex Carey, Pat Cummins (capt), Mitchell Starc, Nathan Lyon, Scott Boland.
England XI: Rory Burns, Zak Crawley, Dawid Malan, Joe Root (capt), Ben Stokes, Ollie Pope, Sam Billings, Chris Woakes, Ollie Robinson, Mark Wood, Stuart Broad.
