Pallekele - Sri Lanka won the toss and elected to bat first against Australia in the fifth and final one-day international in Pallekele on Sunday.
The hosts have lost the series 3-1 and are playing for pride. They are without injured skipper Angelo Mathews and are led by wicketkeeper-batsman Dinesh Chandimal.
Mathews, who suffered a calf injury in the previous ODI in Dambulla, is also doubtful for the team's two Twenty 20 internationals against Australia.
Sri Lanka have made four changes to the side that suffered a crushing loss on Wednesday in Dambulla, with Danushka Gunathilaka, Upul Tharanga, Dasun Shanaka and Suranga Lakmal added to the starting lineup.
The David Warner-led Australia are unchanged from Wednesday's series-clinching win.
Sri Lanka: Dinesh Chandimal (capt), Kusal Perera, Kusal Mendis, Dhananjaya de Silva, Danushka Gunathilaka, Upul Tharanga, Sachith Pathirana, Dilruwan Perera, Amila Aponso, Dasun Shanaka, Suranga Lakmal
