Half-centuries from David Warner and Shaun Marsh helped Australia claim a seven-wicket win and an unassailable 3-0 lead in the one-day international series against England in Sydney.
Needing a victory to keep the five-match series alive and raise spirits on what has been a tour to forget, only Eoin Morgan (54) posted a half-century as England struggled to 243-9.
Tim Bresnan's unbeaten 41 down the order gave the tourists, who won the toss at the start of the day, faint hope, but Australia made mincemeat of their opponents once again to reach their target with 10 overs to spare.
Warner, who could have been out without facing a ball, crashed 71 from 70 balls in a 78-run stand with Marsh for the second wicket after Aaron Finch had departed for 22 in the seventh over.
On Warner's wicket - driving Ben Stokes to cover - at 122-2 in just 21 overs the hosts were already well-placed before Marsh was joined by Michael Clarke, the pair adding 51 before the Australia skipper was bowled by Ravi Bopara for 34.
Any lingering hopes England might have had were dashed by nemesis Brad Haddin, who continued his sparkling winter with the bat as he smashed 37 not out from 33 balls with Marsh unbeaten on 71.
Nathan Coulter-Nile (3-47) was the pick of the Australia bowlers, but it was the recalled Dan Christian who turned England's innings with the wickets of Morgan and Jos Buttler in successive overs.
England have been criticised for leaving their hitting too late, but openers Cook and Ian Bell combined for a run-a-ball 50-run stand with their intent to attack the 10-over powerplay noticeable.
Cook hit five fours and a six, easing Coulter-Nile over the square-leg rope, as he raced to 35 before forcing a back foot drive straight to Glenn Maxwell at cover.
Bell survived a sharp chance when Finch could not hold on at short point, but was then caught out by Warner's direct hit from the deep and perished for 29.
England elevated Stokes, after out-of-sorts Joe Root was omitted, but any notion he was sent in to pinch-hit was ruled out by a laboured 15 from 39 balls.
With Gary Ballance he simply could not get away Australia's spinners, Xavier Doherty and Maxwell, who combined in tandem to concede 38 runs in 13 overs.
Stokes fell during that time to more excellent Australian fielding, with skipper Clarke holding on to a low catch with his non-preferred right hand at backward square leg.
Ballance then picked out the deep cover fielder off Coulter-Nile, after taking 42 balls for his 26, and England were on 121 for four in the 29th over.
The onus was again on Morgan, the centurion at the Gabba, to revive matters and the left-hander and Bopara partnered for the second half-century stand of the innings, which Morgan brought up with a straight six off Coulter-Nile.
But Bopara was out soon after, and from the last ball of the powerplay, when he prodded at a James Faulkner ball that a diving Haddin gloved.
Crucially Morgan and Buttler, who smashed a century stand in Brisbane on Friday to get England to 300, quickly followed him.
Morgan did not want to leave when Christian scooped a catch off the surface in his follow through, to prompt a confrontation with Clarke, who believed he should have taken the fielder's word.
Christian, one of three Australia changes, then caught Buttler in two minds with a slower ball he chopped on to his stumps before Tim Bresnan's late flourish, with 41 from 36 balls, gave England false hope.
