Some Australian rugby Olympians will be sent for alcohol counselling as the entire sevens squad cops a formal warning for a drunken return flight from the Tokyo Games.

Rugby Australia (RA) has detailed the sanctions while also promising to pay for the damage in a player's room at the athletes' village in Tokyo.

Some sevens players and rowers got drunk and disobeyed cabin crew on their flight which left Tokyo last Thursday and arrived in Sydney on Friday.

RA's integrity unit investigated the flight and also the room damage.

"The investigation found that a number of members of the team were drinking excessive amounts of alcohol on JAL 51, while also being disruptive to cabin crew and other passengers onboard the flight," RA said in a statement on Thursday.

"There is no evidence that any JAL property was damaged or mess in seats, aisles or bathrooms was made by the men's rugby sevens team.

"All members of men's rugby sevens team have been reprimanded for this behaviour.

"They have also been formally warned about their future conduct.

"Certain team members will also undergo education and counselling sessions regarding behaviour and alcohol consumption."

Australia's men's sevens beat only South Korea in the pool stages before losing to Fiji in a quarter-final.

"Whilst we acknowledge the disappointment experienced through their Olympic campaign as well as the challenging environment all athletes have had to deal with since the start of the pandemic, this is not an excuse for this behaviour," RA chief executive Andy Marinos said.

"Rugby Australia has a zero-tolerance approach towards poor behaviour and expects the highest standards of conduct at all times.

"It is without doubt that this will have a bearing on how we look at the sevens environment going forward."

RA is understood to be on the verge of examining its funding of the sevens program.
