Australian team boss Ian Chesterman says no disciplinary action will be taken after 10 members broke COVID-19 rules in the Olympic Games village.

A group of athletes sparked a COVID-19 scare in the Australian Olympic team after mingling with other residents inside the Games village.

Team chef de mission Ian Chesterman said none of the Australians involved in the Saturday night incident had tested positive and they had rejoined the group.

“It was a very minor offence – I’m not taking any disciplinary action, none was necessary,” Mr Chesterman said.

“It didn’t lead me to any great concern.”

Mr Chesterman said the incident involved the Australians “mingling” outside of the team’s direct allotment.

He said they had finished their competition at the Olympics and the incident involved “around about” 10 members of the Australian Games team.

Olympic athletes are having to abide by strict COVID-19 protocols and there are no crowds at Tokyo competition venues.

A large group of Australian competitors is about to return home on a charter flight and all of them will go into two-week quarantine.
