Darren Sammy led West Indies to a six-wicket victory over Australia in the World Twenty20 tournament in Mirpur.
Australia, who won the toss and chose to bat, made 178-8 in their 20 overs at the Shere Bangla National Stadium.
However the defending champions reached their target with two balls to spare as Sammy blasted 34 from 13 balls.
West Indies now have two wins from three matches in Group 2 and are in a strong position to reach the semis, while Australia are teetering on the brink of elimination after their second successive defeat.
The Baggy Greens signalled their attacking intent from the start with openers Aaron Finch and David Warner putting on 33 for the opening wicket in just 22 balls.
However Finch, Warner plus Shane Watson and George Bailey had all departed before the halfway point of the innings.

Glenn Maxwell was his typical destructive self, smashing three sixes in 45 from 22 balls, but he went in the 12th over with the score on 100.
Brad Hodge kept the scoreboard moving, with 35 from 26, and Brad Haddin made a late flurry with 15 from seven balls after a remarkable catch from Dwayne Bravo accounted for James Faulkner.
In their reply, West Indies openers Chris Gayle and Dwayne Smith blasted 50 from the opening five overs before the latter was caught behind off Mitchell Starc for 17.
Gayle brought up his half-century off 31 balls but he picked out Maxwell off leg-spinner James Muirhead for 53.
Maxwell then caught Lendl Simmons (26) off Doug Bollinger to leave the men from the Caribbean needing 72 off the final six overs.
Marlon Samuels went cheaply, but Bravo made 27 from 12 balls before Sammy hit Mitchell Starc's penultimate over of the innings for 19 and then back-to-back sixes off Faulkner clinched the victory.
