Australian athletes damaged beds in their Olympic village hotel rooms and put a hole in a wall before leaving, the country's Olympic committee says. Some athletes also showed "unacceptable behaviour" on their flight home, officials added. But Australia team boss Ian Chesterman said no disciplinary action would be taken as the athletes had apologised.

He added that the damage was "minor" and that it was "not the hardest thing to break the cardboard bed". But the Australian Olympic Committee said the national governing bodies of football and rugby union were investigating reports of rowdy behaviour on a flight into Sydney last Friday. Chesterman said: "Some young people made a mistake - they had left the rooms in a condition that was unacceptable."

He added: "The rooms were not completely trashed in any way. "It is a book as old as time: a good young person makes a mistake, chapter two is a good, young person is full of remorse. "Chapter three is a good young person learns from the mistake and becomes a better person." Rugby Australia said it had launched its own investigation after being informed by Australian team officials of "unacceptable" behaviour by rugby and football players on the flight home from the Olympics.
