An investigation has been launched into alleged alcohol-related misconduct by the Australian rugby 7 and soccer teams on their way home from the Tokyo Olympics.

Japan Airlines has sent a written complaint to the Australian Olympic Committee following the inappropriate behavior on the flight, 7 News reported Tuesday.

The AOC confirmed that it had been made aware of “unacceptable behavior” by members of the Rugby and Football Code on the flight to Sydney on July 30th.

Matt Carroll, chief executive officer of AOC, said while multiple sports shared the flight, rugby and soccer teams had taken full responsibility.

“Although there has not been a formal complaint from the airline, we have been made aware of unacceptable behavior and I raised the issue directly with our member sports CEOs,” said Carroll.

“It is extremely disappointing, but both rugby and football have told me that such behavior is certainly not acceptable in their sport and have sincerely apologized to the Australian Olympic team.

“The CEOs are committed to taking the appropriate action and reporting back to us.”

After becoming aware of the bad behavior, the AOC immediately held a meeting with the CEOs of the sports that had representatives on the flight.

Mr. Carroll urged the CEOs to “deal immediately with the behavior problems of their players and officials,” said a statement released by the AOC.

Antics in the Olympic Village

It follows reports that a handful of athletes from the Australian rowing and rugby teams left their rooms in ruins in the Olympic Village.

Rooms were reportedly damaged and cleaners called in to clean up vomit.

The Australian Olympic Committee downplayed the allegations, saying few athletes were involved in the “disgusting” state rooms.

Players reportedly bothered Australian teammates and athletes from rival nations who were still competing during their wild antics on Friday and Saturday nights.

Ten Australian athletes were forced to temporarily isolate themselves and have Covid-19 tests after breaking Olympic rules and partying with athletes from other countries.

Australian head of mission Ian Chesterman said the matter was a “very minor offense” and all athletes returned negative Covid tests.

Any punishment would be imposed by the national athletes’ associations, Chesterman said.
