The Irish Rugby Union (IRFU) is considering charging the Australian Rugby Union for dressing room damage caused by a Wallabies staff member following the Test at Aviva Stadium in Dublin, the Irish Examiner reports.
The newspaper reported that a door and hinges were broken at Lansdowne Road, causing "a few thousand euros" worth of damage.
The ARU owned up to the incident soon after the 26-23 loss.
ESPN has been told that Michael Cheika was not involved in the incident, even though he has "form" having accidentally smashed a glass door at Canberra Stadium last year after a Waratahs defeat.
ESPN has been told that two players and one staffer were involved, contrary to a official team statement saying "there was an accident after the match involving one of our support staff".
The Wallabies played down the incident on Wednesday, insisting it was not related to an angry outburst.
"There was an accident after the match involving one of our support staff," a Wallabies spokesman said. "We made the IRFU aware of this on the evening of the game and have offered our assistance in any way if required."
The newspaper reported the IRFU would not comment publicly but was weighing up whether to bill the ARU for the damage.
