Captain Aaron Finch (44) and Steve Smith (53) got Australia off to a strong start as they chased a target later revised to 282 from 44 overs after an interruption, but Sri Lanka claimed wickets at regular intervals.
Wanindu Hasaranga was the pick of bowlers, taking four for 58 to keep the hosts in contention but Marcus Stoinis (44) and Maxwell, who hit six sixes and six fours, saw Australia home.
