MELBOURNE (Reuters) - Australia captain Michael Clarke signed off in style from international one-day cricket on Sunday by top scoring in his country's crushing seven-wicket victory over New Zealand in the World Cup final.

After dismissing New Zealand for 183 in 45 overs before a crowd of 93,013 at the Melbourne Cricket Ground, Australia cruised to their fifth World Cup with Clarke scoring 74 in the home team's 186 for three from 33.1 overs.

Clarke said the Australian team had played really well through the match.

"It has been an honour and a privilege to represent my country in both test and one-day cricket. The time is right for me to step down from ODI cricket," he said.

New Zealand captain Brendon McCullum, whose side were unbeaten in the tournament before Sunday's match, said: "We played some outstanding cricket but we ran into an outstanding team in Australia. They continue to set the standard."
