A further nine members of the Wallabies squad have been reprimanded for their actions in regards to the incident, which took in midweek prior to the tourists' 32-15 triumph in Dublin.
Five players will serve their suspension in Saturday's fixture against Scotland at Murrayfield, including wingers Adam Ashley-Cooper and Nick Cummins, flanker Liam Gill, hooker Tatafu Polota-Nau and prop Benn Robinson.
Fellow prop Paddy Ryan's ban will not come into effect until Australia face Wales on November 30, as regulations require four props to be involved in a matchday squad.
Dave Dennis, Kane Douglas, Saia Fainga'a, Bernard Foley and Nick Phipps received written warnings, while Scott Fardy, Mike Harris, Ben McCalman and Nic White have also been spoken to.
"Everyone in our squad is required to comply with and adhere to high standards of ethical conduct both on and off the field," coach Ewen McKenzie said.
"Those standards were compromised in the lead-up to Saturday's victory over Ireland with a group of players making the decision to stay out late and consume inappropriate levels of alcohol during the early hours of Wednesday morning.
"Let's be clear - these are internal sanctions and aren't a result of any complaints or reports of inappropriate or sinister behaviour while our players were out. Instead, we have chosen to address an issue that has come up internally and we are now being up-front about it.
"We've done this because we need to continually reinforce the need for our players to make smart decisions to benefit the team.
"The worst thing you could do for the Qantas Wallabies in the long-term is do nothing because that would mean we would be ignoring poor culture and a significant performance issue.
"We will always take action in relation to examples of poor culture when it's warranted. Doing nothing to address poor behaviour will never be an option. We've taken on the challenge of re-defining our team culture."
McKenzie insists the absence of key players will not be used as an excuse for poor performances, as Australia look to arrest a run of two straight defeats against Scotland.
He added: "There is no doubt having talented players unavailable will put this team under significant pressure but we won't be using this situation as an excuse."
