Australia's Mitchell Starc continued his impressive World Cup campaign with a four-wicket haul as Scotland collapsed to 130 all out in Hobart on Saturday.

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.

Australia captain Michael Clarke -- passed fit after missing training in midweek to rest his hamstring injury -- opted to field first after winning the toss in this Pool A fixture.

Scotland have still to win a World Cup match, having now taken part in three editions -- a run of 13 games -- and all four of their previous one-day internationals against Australia had ended in thumping defeats -- by six wickets in 1999, 203 runs in 2007, 189 runs in 2005 and 200 runs in 2013.

Opener Kyle Coetzer -- who made 253 runs in Scotland's first four matches of this tournament -- fell for nought, his second successive duck, when his flat-footed drive off Starc was caught by Steven Smith at third slip.

MacLeod holed out off Starc and 36 for two became 37 for three when Scotland captain Preston Mommsen fell for a second-ball duck when he mishooked a Watson bouncer to Starc at deep backward square leg.

Wickets fell in clusters, with 50 for four becoming 51 for five when off-spinner Glenn Maxwell struck first ball, Richie Berrington chipping tamely to cover.

Left-hander Machan's enterprising 35-ball innings, including six fours, ended when he turned a short ball from Cummins to James Faulkner at long leg.

Scotland were 130 for eight off 25 overs when rain fell and their innings was finished four balls after the resumption, with Davey and Iain Wardlaw (nought) both undone by Starc yorkers.
