Surrey swing bowler Tom Curran inspired England to a thrilling 12-run win over Australia in the first international played at the new Optus Stadium, Perth.
Jason Roy gave England a fine start with 49 from 46 balls but Joe Root (62) was the only man to reach fifty as they were all out for 259 in the 48th over.
Marcus Stoinis hit four sixes in his 87 to guide Australia to 189-4 in reply.
But Curran, 22, in his only third ODI, took 5-35 as Australia were 247 all out to give England a 4-1 series win.
It seemed as if England would rue three dropped catches but Curran’s spirited spell of fast, accurate bowling ensured a 19th win in their last 22 matches.
They now turn their attentions to a Twenty20 tri-series with Australia and New Zealand, beginning next month.
Australia seamer Andrew Tye’s 5-46 caught the eye at the IPL auction, where he was purchased for $1.1m (£780,000) during the interval in Perth.
The general consensus was that England’s total was not enough and although Curran dismissed David Warner with a devastating yorker in the fourth over, Stoinis soon displayed more clean hitting to reach fifty for the third time in the series.
Steve Smith again looked strangely out of form and having narrowly been adjudged not out stumped on nought, he departed for a painstaking 12.
The captain plundered 687 runs in the emphatic Australian Ashes victory but has scored only 102 runs in his five innings in the one-day matches, falling to spin on four occasions.
Stoinis looked to have put Australia in the ascendency at 189-4 when he lofted an Adil Rashid full toss to long on, where Curran took an excellent low diving catch.
Curran claimed the important wicket of Glenn Maxwell lbw with a superb inswinger overturned on review, and ousted Starc two balls later.
Tim Paine was dropped by Alex Hales and Australia added 33 for the ninth wicket before Curran returned to expose their batting frailties in the limited overs game with further stunning yorkers, removing Adam Zampa and Paine in consecutive overs.
