Australia completed an unbeaten home summer with an eight-wicket victory over West Indies in the second Twenty20 international.
Set a target of 139, opening batsman David Warner hammered 67 from 29 balls to turn the run chase into a formality.
The result was never in much doubt after Warner hit three sixes in Kemar Roach's opening over, which disappeared for 24 in all.
He went on to complete the second quickest T20 international half-century in history from just 18 deliveries, including five fours and five sixes.
Warner was well supported by Shane Watson during an opening stand of 99 in 7.4 overs, as West Indies tried six different bowlers without success.
It was left-arm spinner Nikita Miller who finally made the breakthrough, Warner holing out to Kieron Pollard on the midwicket boundary.
Watson's innings had been somewhat overshadowed to that point but he progressed to 50 from just 26 balls and went on to finish unbeaten on 62.
Miller (2-56) picked up his second wicket when Brad Haddin (6) chipped a catch to Runako Morton at cover with one required.
But Daniel Christian (4no), making his international debut, hit his second delivery for four to seal Australia's win, and a 2-0 series success, with 8.2 overs to spare.
Earlier, West Indies were restricted to 138-7 after choosing to bat first at the Sydney Cricket Ground.
The tourists started positively with Chris Gayle and Travis Dowlin taking the attack to opening bowlers Shaun Tait (1-27) and Ryan Harris (2-27).
But, not for the first time during West Indies' winless tour Down Under, Gayle's dismissal for 12 prompted a collapse.
Morton went first ball and was swiftly followed by Pollard (5), Wavell Hinds (0) and Dowlin, who contributed a 32-ball 31 before being out to a spectacular catch on the boundary from Steve Smith.
Dwayne Smith (8) and Denesh Ramdin (9) also offered little resistance to leave West Indies struggling on 98-7 in the 17th over.
But a belligerent eighth-wicket stand of 40 between Narsingh Deonarine (36no) and Darren Sammy (26no) at least averted complete meltdown.
Australia have been relentless during their home season across six Tests, 10 one-day internationals and three T20s with West Indies and Pakistan - winning them all except for the drawn second Test against West Indies and the third one-day international against the same opponents, which was washed out.
