West Indies delighted a patient crowd with a seven-wicket win over Australia in a rain-shortened Twenty20 encounter.
The match in Barbados had to be reduced to 11 overs per side and Australia set a tough target by scoring 97-3.
Luke Ronchi (36) and Shaun Marsh (29) marked their international debuts by sharing an opening partnership of 57.
But Xavier Marshall set West Indies on their way with 36 and Dwayne Bravo hit three sixes in an unbeaten 28 to see them home with 11 balls to spare.
Following the Test series which Australia won 2-0, both sides had a totally different look.
The tourists brought in Cameron White, David Hussey, Shane Watson and James Hopes along with Marsh and Ronchi, all of them having played in the recent Indian Premier League.
West Indies, meanwhile, gave debuts to wicketkeeper William Perkins, batsman Andre Fletcher and fast bowler Kemar Roach and it was Perkins who played the most audacious shot of the match by squatting low to flip fast bowler Brett Lee over his shoulder for four.
Following the delayed start, Australia wasted no time in getting the scorecard ticking over as Marsh produced a straight six off Jerome Taylor in the opening over.
The left-hander, son of former Australia batsman Geoff Marsh, later added another off Roach but one ball later was superbly caught by Xavier Marshall at deep mid-wicket.
It was Roach's second wicket, having had Ronchi caught in his previous over, but Bravo's second-ball dismissal of Hussey, whose brother Mike was also in the Australian team, was their only other success.
The West Indies batsmen had no time to assess the bowling but Marshall showed he did not need to by hooking the first ball of their reply for six off a startled Lee.
The highly promising Jamaican continued in the same vein, depositing two balls into the crowd in Mitchell Johnson's opening over, which cost 20 runs.
Marshall dominated a first-wicket stand of 53 with Perkins, scoring his runs off only 15 balls before he was smartly run out by Watson, who fielded off his own bowling.
Perkins went the same way for nine, beaten by Ricky Ponting's direct hit at the bowler's end and Denesh Ramdin only managed eight before he was caught in the deep off Watson.
But Bravo hoisted a long-hop from leg-spinner White over the rope at backward square leg, slashed Johnson over deep third man and finished off the match with another six, this time depositing a ball from Watson over deep mid-wicket.
