QRL Managing Director Robert Moore confirmed on Monday night that the organisation will exclude two players from its representative programs for the next 12 months.
Cronulla Sharks player Valentine Holmes broke curfew during the Emerging Origin camp and is subject to further investigation by the QRL and NRL Integrity Unit.
Melbourne Storm player Cameron Munster has been excluded solely for breaking curfew.
Moore said it was possible that action would be taken against other players if they were identified as breaking curfew.
Maroons coach Kevin Walters expressed his disappointment today.
"On Saturday afternoon we sat down as a group and spoke about the importance of making the right choices," Walters said.
"Regrettably, there were some players who made poor choices after we had wrapped up the official part of that day's program."
While bitterly disappointed with the actions of some individuals, Walters said he took a lot of positives away from the camp.
"I can see a real chemistry amongst them all," Walters said.
"Although they come from different clubs and have different backgrounds, they've been connected over the years through Queensland Rugby League development programs."
