James Faulkner (16*) and David Warner (21*) took just two overs to knock off the remaining 39 runs to seal victory for the Aussies and ensure that they avoid South Africa in the quarter-finals of the tournament.

SCOTLAND: Callum MacLeod, Kyle Coetzer, Matt Machan, Preston Mommsen (c), Freddie Coleman, Richie Berrington, Matthew Cross (wk), Josh Davey, Rob Taylor, Michael Leask, Ian Wardlaw
Starc has been all over Coetzer early doors and now gets his man. The Scot looked understandably unsure against the 150kmph left-armer and gets stuck in the crease flashing at one outside off-stump. There is no foot movement at all and Steve Smith takes a sharp catch above his head at third slip.
A breezy little knock from MacLeod comes to an end. He had thrived on width in his 22 - double his highest previous score at the tournament - but cuts Starc straight to David Warner at point. The bounce perhaps got a bit high on him, but he will no doubt be disappointed that he couldn't keep the ball down.
Scotland's skipper goes quickly as he top edges a hook off Watson, and Starc does the rest backtracking at square-leg. Mommsen has arguably the best technique and usually the best temperament of the Scotland lineup, but should not have been playing that shot so early in his innings and was never in control of it.
A third Scottish batsman goes for a duck as Johnson gets in on the act. Coleman pushes too hard at one angling across him and an edge flies through to the slips, where Clarke takes a good catch diving to his right.
Maxwell burgles a wicket first ball with a friendly half-volley which Berrington slices into the hands of Warner at cover. There is a gulf in class between these sides, but no excuse for a dismissal as soft as that.
UPDATE: Zimbabwe have been bowled for 287 in the penultimate over against India. In his final ODI, captain Brendan Taylor starred with a wonderful 138, well supported by Stuart Williams with 50. Pace trio Mohammed Shami, Umesh Yadav and Mohit Sharma all took three wickets for India.
Cummins is back into the attack with a much-needed wicket. Machan tries to help a short ball around the corner, but gets too far underneath the ball and it just about carries to Faulkner at long-leg. The left-hander played well and aggressively, but that flaw in his technique has eventually cost him his wicket.
Pace has been Australia's X-factor this morning and there is too much heat on this delivery from Cummins. Cross gets himself into a really awkward position and the ball comes off the shoulder of the bat and goes through for a simple catch to Haddin. Scotland's last recognised batsman is back in the hutch.
Cummins strikes again to leave Scotland eight down. This is almost a replica of a delivery which he bowled to Taylor in the previous over and this time the number nine prods the bat away from his body and the edge goes straight into the gloves of Haddin.
And he immediately comes up with one of his unplayable yorkers! Davey's defence had looked solid, but he can do nothing to keep out an off-stump yorker from around the wicket. The end is nigh.
Indeed Scotland cannot see out the over as Starc bowls last man Wardlaw for his fourth wicket. This isn't quite yorker length, but completely beats Wardlaw for pace as he tried to give himself room.
Finch has been aerial with many of his early strokes and this time he picks out a fielder! He does not get over a loose drive and Coleman takes a good catch diving forward at cover. Taylor has the wicket that he deserved for his opening over.
UPDATE: India are now three down in Auckland, where Ajinkya Rahane has run himself out to leave his side 74-3 off 18 overs chasing 288 to win against Zimbabwe. Virat Kohli and Suresh Raina at the crease.
Another World Cup wicket for Davey, who now has 15 for the tournament. Fine-leg is in the ring and Watson tries a ramp shot which he top edges, with wicket-keeper cross coming round to take an easy catch.
A great catch on the boundary from Michael Leask secures Scotland a third scalp and the big one of the Australian captain. Wardlaw's ill-advised short-ball ploy has cost him 45 runs but now also earned him a wicket as Clarke pulls in the air square, where Leask dives low to take a stormer. A run-a-ball 47 will do Clarke some good, but he no doubt would have liked to see it through to the end.
Panic over. Australia needed only two overs and 10 minutes after the restart to seal a victory which secures them second spot in Pool A. Faulkner (16 not out) slogs a six to get them over the line.
