David Warner will take his place at the top of the Aussie batting order despite battling with sore ribs.
And in a sign he is determined to tough things out, the 35-year-old left hander has refused a pain-killing injection unless the discomfort gets too bad for him once he is in the game.
It means Australia make just the one change to their team from the victorious first Test with the injured Josh Hazlewood replaced by Jhye Richardson as expected.
“He'll be right,” said captain Pat Cummins of Warner.
“He batted yesterday with a bit of discomfort but knowing Davey he's not going to miss this once adrenaline and everything kicks in. So yeah, all good, a little bit sore but he'll be fine.
“I don’t think the plan is for him to have an injection at this stage. It is an option if he needs it, I think he will just go out and bat.
“It's not an injury like a broken bone or anything that will get any worse. It just might be a bit of discomfort.
“He's played close to 90 Tests. I'm sure a lot of them have been played in discomfort or with things going into the game so he'll be fine tomorrow.”
Warner’s availability is a big boost for the Aussies since he has a formidable record at the Adelaide Oval and hit a career best 335 not out against Pakistan in 2019.
But Cummins is not taking anything for granted ahead of a pink ball game where conditions can change suddenly and without warning to make life tricky.
“There are more unknowns in day/night cricket,” he added. “You feel like you learn something new each time you play one.
“The unknowns are the leveller. You might get a period of play when the ball starts swinging around or nipping around and you can’t explain why.
“You can look at information and data and get what you want out of it, but it is a game with so many unknowns you can’t plan for everything.”
England can plan for Richardson though who will win a third Test cap to go with his debut in a day/night match in Brisbane where he picked up 5-45 against Sri Lanka across two innings.
“Josh is a big void to fill but we feel really confident Jhye can step straight in,” added Cummins, who will probably give him the new ball too.
“He's slightly shorter, skiddier, as opposed to Joshy's tall bounce. He's really skilled, can swing the ball both ways, can nip the ball, and he's a bit faster than you think.
“He's worked incredibly hard, had a great start to this year for Western Australia in shield cricket and we just think he's firing and really excited to see him out there.”
