Sri Lankan skipper Dasun Shanaka won the toss and elected to bat in the dead-rubber fifth one-day international against Australia in Colombo on Friday.
The hosts took an unassailable 3-1 lead in the fourth match against their injury-marred visitors, who are led by opening batsman Aaron Finch.
Finch had one change with Josh Inglis making his ODI debut, replacing Travis Head who hurt his hamstring in the last match.
