Australia's batting woes in the T20 cricket series against the West Indies have continued, setting the hosts a modest 142 to clinch the series in St Lucia.
Captain Aaron Finch opted to bat first after losing the first two matches where he asked the West Indies to take first strike.
But Australia managed just 11 fours and two sixes in their 6-141 total.
They scored just 69 runs off the last 10 overs, three fewer than in the first 10.
They struggled against the dual spin attack of Fabian Allen (1-26 off four) and Hayden Walsh (2-18 off four), and veteran medium pacer Dwayne Bravo (1-17 of three).
A fourth-wicket stand of 59 - Australia's first half-century partnership of the series - between Moises Henriques (33 off 29 balls) and Ashton Turner (24 not out off 22) added some substance to the innings.
Australia didn't capitalise on their opening stand of 41 from the first five overs.
Matthew Wade (23 off 16) made a swift start, striking four boundaries from cover drives and pulls off his first 10 balls, before being bowled by Obed McCoy.
Finch (30 off 31) got a start but again struggled for fluency after two single-digit dismissals, hitting just two boundaries.
Mitchell Marsh, coming off half centuries in the two previous games, was trapped lbw for nine when trying to sweep at left-arm spinner Allen.
Australia lost just two wickets in the first 11 overs, but lost two in the 12th bowled by leg-spinner Walsh.
Carey was caught at extra cover for 13 off the first ball and Finch fell of the fifth, caught at deep midwicket after Bravo dropped the ball with his first touch but with his second pushed it to the adjacent Lendl Simmons.
"The West Indies really executed their plans very well, they didn't really give us a chance to use the wicket," said Henriques, Australia's sole six-hitter.
"The wicket looks pretty good but they rarely hit that good length with pace on, it was either a slower ball into the wicket or wide full yorkers.
"I think we're probably 20 below par."
Finch made three changes to his side, two of them forced by injuries to Ashton Agar and Ben McDermott.
Paceman Riley Meredith and middle order batsmen Carey and Turner replaced spinner Agar and batsmen McDermott and Josh Philippe.
West Indies made just one change, with paceman and first-game hero McCoy coming back into the side for the injured Fidel Edwards.
