|Tri-series final, Perth:|
|Australia 278-8 (50 overs): Maxwell 95, Marsh 60, Faulkner 50; Broad 3-55|
|England 166 (39.1 overs): Bopara 33; Maxwell 4-46, Johnson 3-27|
|Australia won by 112 runs|
England were thrashed in their last competitive match before the World Cup, crumbling to a 112-run defeat in the tri-series final in Perth.
Glenn Maxwell starred with bat and ball for the hosts, scoring 95 and taking 4-46, and Mitchell Johnson took 3-27 on his international return.
England had Australia 60-4 but the hosts recovered to post 278-8.
Johnson swept through England's top order and Maxwell's off-spinners did the rest as England were 166 all out.
England have now lost 13 of their last 15 one-day internationals against Australia in Australia and have only two warm-up games before they face them again in their World Cup opener on 14 February.
Captain Eoin Morgan still has several puzzles to solve, not least his own patchy form with the bat - the left-hander made 121 in the tri-series opener in Sydney but has posted scores of 0, 2 and 0 since.
|Captain Morgan's peak and troughs|
|England captain Eoin Morgan has scored 400 runs in his last 20 ODI innings, at an average of 20. However, if you remove the 121 he scored against Australia in Sydney on 16 January, that average falls to 14.68.|
The hosts were 0-1 after James Anderson dismissed Aaron Finch with the third ball of the innings and David Warner followed in the seventh over, deflecting a lifting ball from Anderson to point.
Stuart Broad did for George Bailey, the under-pressure Tasmanian fending a short ball to short-leg to leave Australia tottering on 46-3.
In-form Steve Smith batted confidently for his 40 but was stumped by Jos Buttler at the second attempt after coming down the pitch to Moeen Ali.
But Maxwell and Mitchell Marsh put on 141 for the fifth wicket, the former demonstrating his full array of strokes and bringing up his ninth one-day international fifty with a reverse pull for four.
Maxwell hit four boundaries in one Chris Woakes over before falling to Broad in the next, while Marsh was run out for 60 soon after.
James Faulkner hit four sixes - including three in one Woakes over - to race to an unbeaten, 24-ball fifty and transform what would have been a below-par total into a testing target.
Anderson was again the pick of England's bowlers with 2-38 while Woakes's bowling figures of 0-89 from 10 overs were the fourth worst for England in ODI history.
England's openers made a confident start before Ian Bell nicked a fine delivery from Josh Hazlewood and wicketkeeper Brad Haddin snaffled a brilliant one-handed catch.
Enter Johnson, who took 37 wickets in Australia's Ashes whitewash of England last winter but had played no international cricket in 2015.
James Taylor never looked settled before skewing Johnson to gully, where Maxwell took an excellent catch diving low to his left.
And when Moeen fended a wicked Johnson bouncer to second slip and Morgan shouldered arms to a straight delivery next ball, England were in disarray on 46-4.
Faulkner picked up his 50th ODI wicket when he had Joe Root lbw with his first delivery, but the Tasmanian all-rounder was forced to leave the field soon after with a side injury.
Buttler looked in fine form before reverse-sweeping off-spinner Maxwell to substitute fielder Pat Cummings and Woakes was gone next ball, offering up a simple caught and bowled.
Broad played some big shots before holing out to deep mid-wicket, Ravi Bopara became Maxwell's fourth victim when he holed out to extra-cover and Hazlewood bowled Steve Finn to wrap up the win.
