David Warner returned to form with a maiden Twenty20 international century to help Australia to a 134-run victory in the opening match of their three-game series against Sri Lanka.
Warner reached 100 from 56 balls as he made the most of some messy bowling from Kasun Rajitha, who finished with nought for 75 from four overs - the most expensive spell in T20I.
Australia finished on 233 for two - their fourth-highest score in T20 cricket - with Aaron Finch hitting 64 and Glenn Maxwell 62.
Sri Lanka never looked up to the task of chasing down the total, losing opener Ajantha Mendis for a duck from the fifth ball of the first over from Mitchell Starc.
Pat Cummins took the wickets of Danushka Gunathilaka and Bhanuka Rajapaksa in consecutive deliveries in the fourth over and the tourists could not recover, managing just 99 for nine.
