Aaron Finch has returned to Australia's XI for the third Gillette T20 International against England at the MCG, but exactly where he will bat in the order remains a mystery.
England have suffered a blow with skipper Eoin Morgan ruled out due to a groin injury, with James Vince taking his place in the side and Jos Buttler handed the captaincy.
Australia won the toss and elected to bowl first as they made one change to the side that won by five wickets on Wednesday in Hobart.
Finch, who missed the opening two games of the series as well as the final two ODIs last month due to a hamstring injury, has returned in place of Travis Head.
D'Arcy Short partnered Warner at the top of the order in Australia's wins over New Zealand and England in the past week, but he's been listed to bat at No.3 and Finch as an opener.
But Warner kept his cards close to his chest when asked about his batting line-up at the toss, leaving the door open for Short to retain his spot at the top and for Finch to move down the order later tonight.
Adam Zampa, the only specialist wrist-spinner in Australia’s squad, had hoped he would win a recall after being dropped for Wednesday's match against England.
But selectors have opted to stick with the bowling attack that orchestrated a stunning England collapse of 7-43. Spinners Ashton Agar and Glenn Maxwell collectively claimed 5-25 between them at Blundstone Arena.
"A lot of countries around the world are opting for two wrist-spinners," Zampa said on Friday.
"It's just the grounds and the situations we've got ourselves in probably that make it a little bit different in Australia.
"We saw the other night that it was the two spinners that changed the game for us so I think definitely having a wrist-spinner that can spin it both ways is always good to have in your team."
In addition to Morgan's absence, England have left out paceman Mark Wood in favour of left-arm spinner Liam Dawson.
Australia will seal a spot in the tri-series final (to be held in Auckland on February 21) with victory tonight.
