Hobart: Australia raced to a seven-wicket win over Scotland in rain-affected game at Bellerive Oval, and finish at second spot in Pool A.
Mitchell Starc took 4-13 and Pat Cummins 3-42 to bowl Scotland out for 130 in 25.4 overs in Hobart.
Michael Clarke, promoted up the order, hit 47 as Australia won with 34.4 overs to spare after a 90-minute rain delay.
They face a quarter-final against Pakistan or Ireland, who meet on Sunday, in Adelaide on 20 March.
Michael Clarke cut a frustrated figure as the umpires suspended play after 25 overs of Scotland's innings for what appeared the lightest of showers. Ground staff only put down the thin hessian cover but the 45-minute break was time seemingly unnecessarily lost - especially from Australia's point of view.
Earlier, Mitchell Starc continued his impressive World Cup campaign with a four-wicket haul.
Left-arm paceman Starc was left on top of the tournament bowling charts with 16 wickets after his burst of four for 14 in 4.4 overs helped the four-time champions, already into the quarter-finals, rip through Scotland's batting.
There were five ducks in the innings, with fast bowler Pat Cummins, recalled in place of spinner Xavier Doherty, taking three for 42 in seven overs.
Matt Machan, who plays for English county side Sussex, top-scored with 40 and Calum MacLeod made 22 but at 79 for seven there was a real chance Scotland would be dismissed for under 100.
However, bold hitting from the ninth-wicket duo of Josh Davey (26) and Michael Leask (23 not out) took the non-Test side to three figures.
Earlier, Australia have won the toss and opted to field.
Both team made one change for Australia -- Pat Cummins replacing Xavier Doherty while for Scotland, straight swap in the seam attack, with Iain Wardlaw returning to the side in place of Alasdair Evans.
