Australia has crashed to an embarrassing loss in the first T20 against the West Indies, losing their last six wickets for just 19 runs in St Lucia.
Chasing 146 for victory, the Aussies seemed to be cruising at 4-108 before disaster struck.
An unthinkable collapse of 7-38 saw the West Indies claim the series opener in an 18-run victory after Australia were bowled out for 127.
Josh Hazlewood starred with the ball in St Lucia, removing Evin Lewis for a second-ball duck and Chris Gayle for four in an incredible opening spell of 2-3 that helped restrict the hosts to 6-145.
Mitch Marsh scored 51, producing his highest T20 score for Australia after being promoted to first drop, as the visitors marched to 3-89 in the eighth over.
But the wheels came off in woeful fashion as Australia being bowled out for in 16 overs.
Marsh, well set and in the box seat to win the match, will be kicking himself after chipping a catch back to spinner Hayden Walsh in the 13th over.
Veteran all-rounder Dan Christian, recalled at age 38 for his first international match in almost four years, scored 10 before picking out Dwayne Bravo in the deep.
Paceman Obed McCoy was named man of the match after removing Ashton Agar, Mitchell Starc and Hazlewood to wrap up victory.
The lack of composure was telling, with Marsh, Christian, Moises Henriques (16) and Matthew Wade (33) the only Australian batsmen to reach double figures.
