George Bailey will be leading the Australian side in absence of Michael Clarke who is suffering from an ankle injury. Clarke has been replaced by Glenn Maxwell.
Clarke went over on the ankle during a fielding drill at training on Tuesday.
Earlier Bailey had said, “He will obviously be given right up to the toss on Wednesday to prove he is right to go. There will be a little bit of pain but, if he is 100 per cent, he will play.”
Sri Lanka lead the five-match series 2-1 after the fourth leg in Sydney was washed out on Sunday.
The tourists were chasing 223 runs to take the series after thrashing Australia in the second and third games. They needed 209 more runs off 46.4 overs with all their wickets intact when the umpires took the players off. Australia scored 222 for nine off their 50 overs after winning the toss.
Australia: Phillip Hughes, David Warner, George Bailey (c), David Hussey, Glenn Maxwell, Matthew Wade (wk), Moises Henriques, Mitchell Johnson, Mitchell Starc, Clint McKay, Xavier Doherty.
