England captain Andrew Strauss was hugely disappointed by his team's defeat after they put themselves in a strong position in the sixth one-day international against Australia.
England piled up 333 for six in 50 overs, their record score against the hosts in Australia, with a century for Jonathan Trott.
But they then allowed the home side to make a rapid start and edge over the winning line, with Paul Collingwood unfit to bowl after suffering a back spasm while batting.
A two-wicket defeat left England trailing 5-1 in the series, with one match remaining for the tourists to salvage some pride.
Asked whether the match was a bittersweet experience for England, Strauss told Sky Sports: "Just bitter I think.
"We had a very good batting performance, Jonathan Trott played outstandingly well and was well supported by a few of the lads.
"And 333 is a good score on any ground.
"It was a good wicket but obviously we were not helped by Paul Collingwood not being able to bowl.
"We let them get off to far too fast a start and they were able to keep up the rate.
"It was very, very disappointing we were unable to restrict them to less than 333.
"But all credit to the way they played. In the end they walked out worthy winners."
As for Collingwood's situation, Strauss reported: "He's okay.
"He had a back spasm so hopefully should recover fairly quickly.
"Otherwise, the rest of us got through the game okay."
