ONE-DAY SERIES, SYDNEY: England 292-7 (50 overs) beat Australia 200-9 (38.5 overs) by 92 runs
England completed their first victory over Australia since the 2005 Ashes after Ed Joyce's century in Sydney.
Joyce scored England's first century in 15 matches
Joyce, dropped twice, made 107 from 142 balls to help better by 66 England's previous best of the one-day series.
Chasing 293, Australia were bowled out for 200 in 38.5 overs, with Andrew Symonds having retired hurt on 39. Matthew Hayden was top-scorer with 51.
Liam Plunkett (3-24) and Sajid Mahmood (2-38) both struck in the first eight balls to cut the hosts to 4-2.
It was the fourth-heaviest defeat inflicted by England on Australia in a one-day match.
Despite the victory, and whatever Sunday's result between Australia and New Zealand, England still need to beat the Kiwis on Tuesday to reach the best-of-three series finals.
Marcus Trescothick was the last England batsman to score a one-day ton, 15 matches ago, against Sri Lanka at Headingley last July.
With the World Cup looming, Joyce finally provided England with a viable alternative to the burly left-hander at the top of the order, although his innings was far less aggressive.
On a pitch with good pace and carry, he demonstrated some impressive drives either side of the wicket, although he was also a little lucky pulling and cutting into spaces in the field.
Shaun Tait put down a simple chance at fine leg and Symonds also gave the Irishman a let-off from his own bowling.
But he went on to reach three figures from 136 deliveries with 10 boundaries.
England's bowlers have struggled recently with first-choice opening pair Jon Lewis (ankle) and James Anderson (back) unavailable.
But Plunkett was at his best as he unleashed an inswinging yorker first ball to send Adam Gilchrist on his way.
Plunkett struck first ball on the way to career-best figures
Mahmood, playing his first match of the series in place of Chris Tremlett, followed up with a blazing delivery that Brad Hodge failed to get out of the way of, and he played on.
Plunkett also had Michael Clarke caught wafting at a wide delivery and trapped Glenn McGrath lbw on his way to career-best figures.
The aggressive fourth-wicket duo of Hayden and Symonds dragged the odds back in Australia's favour, adding 71 together in just eight overs
Hayden took 18 off a single over from Andrew Flintoff and Symonds thrashed Monty Panesar's second ball for six.
Fortunately for England, Hayden became overconfident and thrashed Mahmood to cover.
Symonds injured his biceps flaying Mahmood through the covers and had to depart shortly afterwards.
And England were soon into the tail after Ravi Bopara - in his second over of international cricket - saw Mike Hussey play onto his stumps.
Tait denied McGrath the number 11 batting position for the first time in his 235-ODI career but the veteran survived just seven balls.
Ian Bell ran out last man Tait with a direct hit to finish the job.
With captain Ricky Ponting resting a hip problem, the home side lacked their usual urgency in the field under Gilchrist, conceding 19 wides.
Fiery pace bowler Tait, making his debut with Brett Lee taking a break, was responsible for nine.
Joyce and Mal Loye (29) made the most of that early chance to put on 58 for the first wicket, England's best opening stand of the series so far.
Loye had time to unleash his trademark slog-swept six off Bracken but a similar shot at McGrath brought a top edge into his helmet grille and he was out next ball.
Bell (51) joined Joyce in a low-key partnership worth 111 in 22 overs, with successive cut fours off McGrath early in his innings the only time he ventured to hit out.
McGrath returned to the attack with immediate success as Bell tried to pull the first delivery after the drinks break - a short one from the veteran - and departed shaking his head in dismay.
But Andrew Strauss enjoyed a confident run-a-ball cameo 26, his dismissal from an inventive shot trying to keep the rate high in the late overs.
And Jamie Dalrymple hooked McGrath for six in making 30 from 18 balls.
