David Warner made a blistering half-century and Mitchell Starc starred as Australia beat West Indies by 31 runs at The Gabba to seal a 2-0 Twenty20 International series whitewash.
Holders Australia continued their preparations for the T20 World Cup on home soil with another victory in Brisbane on Friday, Warner making 75 off 41 balls and Tim David 42 from just 20 deliveries in their total of 178-7.
The Windies could only muster 147-8 in reply, Starc the pick of the bowlers with 4-20 and Pat Cummins (2-32) taking his 50th Twenty20 International wicket.
Australia will now travel to Perth for the start of a three-match T20I series against England on Sunday, while West Indies will have to come through their first-round group to qualify for a World Cup Super 12 spot.
The excellent Alzarri Joseph (3-21) dismissed Cameron Green in the second over, but Warner and Aaron Finch got Australia up to 45-1 at the end of the powerplay.
Warner raced to his half-century in 30 balls, but was caught and bowled by Odean Smith in the 12th over after captain Finch fell for a scratchy 15.
Glenn Maxwell was run out for only one and Steve Smith (17) was bowled by Joseph, but David cleared the rope three times in a swashbuckling knock to give Australia some impetus before he was trapped lbw by Obed McCoy (2-33).
Kyle Mayers was brilliantly caught and bowled by Starc in the first over of the Windies' run chase, but Johnson Charles and Brandon King steadied the ship with a stand of 50.
Adam Zampa redeemed himself for dropping Charles on two by getting King (23) stumped and Starc returned to see the back of Nicholas Pooran.
An unconvincing knock from Charles (29) was ended by Green as the wickets continued to tumble, Starc doing the bulk of the damage as Akeal Hosein's knock of 25 came with the Windies never really looking like squaring the series.
Warner sets the tone
Opener Warner was outstanding at the top of the order, laying the foundations for a total that proved to be too big for the Windies to chase down.
He demonstrated his great power and sweet timing, striking three sixes and hitting another 10 boundaries as he registered a brilliant 23rd half-century for his country in the shortest format.
Starc fires, Cummins brings up half-century
Australia will be relying on Starc to be firing on all cylinders when they attempt to retain the World Cup and he bowled beautifully in Brisbane, with a mixture of control and variety.
Cummins was more expensive, but the Test captain reached the 50 T20I wickets landmark in his 44th match.
