The ARU integrity unit have been called into action to investigate the Western Force's ill-disciplined tour of South Africa last week.
Wallaby newcomers Dane Haylett-Petty and Adam Coleman were caught up in the drama during the team's stay in a Bloemfontein hotel.
A vase was reportedly broken after a play fight between brothers Dane and Ross Haylett-Petty turned heated, while Coleman had a loud argument with prop Francois Van Wyk.
Prop Pek Cowan was stripped of the captaincy for Saturday night's clash with the Stormers in Perth after being among the players to break the 1am team curfew following the team's 30-29 loss to the Cheetahs last week.
The Force decided not to stand down any players for this week's match, but that could change once the ARU completes its investigation.
The drama comes just a month after the ARU formed an alliance with the Force in a bid to save the struggling Perth-based franchise from going under.
