Peter Handscomb will make his World Cup debut and Marcus Stoinis has proven his fitness but Australia could yet have a late selection twist ahead of Thursday's blockbuster World Cup semi-final against England.
Coach Justin Langer confirmed on Wednesday that Handscomb would replace the injured Usman Khawaja in the XI for the knock-out final at Edgbaston.
However, Langer refused to guarantee spots for Glenn Maxwell and Stoinis, meaning Matthew Wade - who has joined the 15-man squad as a replacement for Khawaja - could also be drafted into the XI ahead of Maxwell.
"I'll tell you the truth, Peter Handscomb will definitely play, 100 per cent. He deserves it - he was really stiff not to be on this tour," Langer said.
"He was so unlucky not to be in the initial squad after what he'd done to help us get to that point.
"He's in good form, he played well for Australia, he gives us nice balance through that middle order, he's got great temperament, he plays the spin well and he's on top of his game. So he'll definitely play."
Handscomb played the last of his 21 one-day internationals against Pakistan in Dubai in March, and was unfortunate to be overlooked for this tournament because Steve Smith had returned from suspension. The Victorian has 628 runs at 34.88 with one century in his ODI career - that century coming against India in Mohali in March.
Stoinis passed his fitness test on an overcast afternoon at training where he batted, bowled and fielded and was declared fit, having experienced a right side strain against South Africa on Saturday.
He had been in doubt, with Mitch Marsh drafted in as cover at training, but yet again proved his fitness, having had to do so at Trent Bridge earlier in the tournament after missing two matches, also because of a side strain.
"He looks good. It was a very good net session actually. There was a bit of heat again, it was very competitive and that always brings the best out in Stoin. He did a good job today and he's fit to go," Langer said.
The coach-selector said Handscomb was likely to bat at No. 4 or No. 5, meaning Smith was likely to be elevated to No. 3 - although Wade was also under consideration.
"Well, he's in the squad, so yeah, like everyone in the squad, there's potential for him to play, definitely," Langer said.
The pugnacious Wade, now seen more as a specialist batsman rather than gloveman, had been in superb touch as an opener with the Australia A squad in England, thumping two centuries in his past four innings. He may be needed if Australia feel more batting power is needed to combat a high-octane England batting line up and what will be a flat pitch.
Should Wade play, that could leave Maxwell as the fall guy, the Victorian having failed to have an impact with the bat in nine matches. While he has a brilliant strike rate of 163.14, Maxwell has only 155 runs at 22.14. His bowling has been important but he is wicketless in 49 overs.
Stoinis, while fit, could also be put under the selection spotlight if the Australians feel they could scramble 10 overs between Maxwell's off spin and the part time spin of Aaron Finch and Smith.
Asked if Stoinis or Maxwell were guaranteed of playing, Langer replied: "We'll pick our 11 and you'll see it at the toss, I reckon."
If Stoinis does play, Langer is confident he won't break down in what will be the biggest game of the allrounder's life. He said that confidence came from the "last seven months".
"We've got a group of players that have been together for the last six or seven months. We got to the World Cup semi-final, we've had a couple of hiccups along the way. But those guys have done a great job for us to get us there," he said.
"Everyone in the squad has played their role, and played a part of our success. That's where I get my confidence that they'll be good for the World Cup semi-final."
