England's tour of Australia sunk to new depths as the hosts clinched an unassailable 3-0 lead in the one-day series to add to their Ashes whitewash after a routine seven-wicket win in Sydney.

David Warner and Shaun Marsh's half centuries allowed Australia to cruise to victory with 10 overs remaining after England had made just 243 for 9 from their 50 overs.

Eoin Morgan made 54 and Tim Bresnan a sprightly 41 from 29 balls to help recover an England innings which had seen them fall to 91 for 3.

But in reply Australia never looked in trouble and after a 71 from Warner, Marsh also made 71 from 88 balls to see Michael Clarke's side home and pile further misery on England.

"I think our bowlers did a fantastic job on a pretty good batting wicket," Clarke said. "The important thing for our bowlers was a bit of cross-seam stuff, take the pace off it."

Alastair Cook's side face two further one-day matches against Australia, tasked with preventing a second successive whitewash on their tour down under, before three t20 internationals end a tour which can only be described as an abject failure.

Cook said: "It's tough to stop them and we've got two more games to try to stop them."

After the six-wicket defeat in Melbourne, England failed to claim their first win of the tour in Brisbane and the convincing defeat to Australia in the third one-day international in Sydney is another indication as to their fortunes this winter.

With uncertainty over the role of test coach Andy Flower, the long-term international future of Kevin Pietersen and captain Cook, the end of the tour can't come soon enough for an England side in complete disarray.

In stark contrast, Australia's brilliance continues and their dominance over England comes 13 months out from the 50-over World Cup on home soil and is a significant indicator as to both their continued improvement and the threat they could pose in 2015.
