Australia secured their World Twenty20 Super Eights spot after a 17-run, Duckworth-Lewis win over the West Indies in Colombo on Saturday.
Chasing a mammoth 8-191, Australia were 1-100 after 9.1 overs, 17 runs ahead of the par score - with Shane Watson (41 off 24 balls) and Michael Hussey (28 off 19) at the crease - when covers were called on.
Play was finally called off 30 minutes later.
West Indies appeared favourites to win their tournament opener after Chris Gayle (54 off 47), Marlon Samuels (50 off 32) and Dwayne Bravo (27 off 21) took the side to a daunting total having won the toss and elected to bat.
Mitchell Starc finished with 3-35 and Watson picked up 2-29 while Pat Cummins, Daniel Christian and Brad Hogg chipped in with a wicket each.
But the Australia chase got off to a brisk start with David Warner (28 off 14) hitting Ravi Rampaul for two sixes and as many fours in the second over that went for 22 runs.
The diminutive opener headed back to the dugout off the first ball of the next over from Fidel Edwards (1-16) when he was caught behind by Denesh Ramdin.
With Watson taking time to get going, Hussey scored quickly, getting a four and a six in successive overs to keep the required rate in check.
Watson soon found his bearing, first muscling Sunil Narine (0-16) over mid-wicket on a free hit and had a slice of luck as well after being dropped in the Samuels (0-22) over in which he hit two sixes and two boundaries.
Just seven balls later, a slight drizzle quickly turned into a heavy shower forcing the umpires to call for the covers.
Earlier, the West Indies lost Dwayne Smith (two) early but Gayle, dropped by Watson on five, made Australia pay, going on an all-out assault after playing out a few quiet overs.
He was particularly severe on Cummins, who went for 18 runs having bowled a maiden previously, and Glenn Maxwell who conceded 17 in his only over.
Gayle fell to Watson in the 11th over with the bowler taking a good return catch off a leading edge but Samuels ensured the run fest continued.
Australia did well towards the end of the innings, picking up wickets regularly to stem the flow of runs but skipper Darren Sammy (12) took the total past 190.
West Indies will now take on Ireland on Monday with the winner going ahead to the Super Eights.
