Some current and former students at St Edmund's College were involved in the activities this week which ranged from harmless fun to misogynistic and illegal acts.

A list viewed by The Canberra Times contains activities for groups of students to complete to be awarded points in the so-called scav hunt.

Some tasks on the milder end included "walk across a pedestrian crossing" and "skull a bottle of milk".

Other dares included performing sex acts with team mates, urinating in someone's mouth and breaking and entering a house to steal a Wi-Fi modem.

Students could get points for sending photos of their genitals to other students and consuming drugs and alcohol.

The list included acts that were degrading to women, such as getting a selfie with a topless woman, "hooking up" with five women consecutively or having sex with "a fat chick".

Teams could get 50 points for reversing through a McDonald's drive through or ordering four sundaes and dropping them on the floor or the restaurant.

St Edmund's College principal Joe Zavone said staff were unaware of the activities until Friday and would have actively sought to stop the scavenger hunt if they had known.

"The investigations into this matter are ongoing. There will be serious consequences for any students who are found to be involved in inappropriate activities, and any criminal activity will be referred to police authorities with whom we will co-operate," Mr Zavone said.

"In no way and at no time does the college condone or support the idea of a scavenger hunt with its vile and unacceptable behaviours."

Education Minister Yvette Berry said on Friday that she was not aware of the specific details of the reported scavenger hunt.

"I have spoken directly with principal Joe Zavone this afternoon [Friday] and I understand he is communicating with the St Edmund's community," Ms Berry said.

"I'm pleased the school is responding proactively. It's up to all of us to maintain the culture of respect that Canberrans are proud of."

Mr Zavone said staff had been informed that only a small number of students were involved and the vast majority of the cohort were not involved.

"Since finding out about the scavenger hunt, we have spoken to a number of our Year 12 students who are highly embarrassed and ashamed that they had some peers involved in this action.

"As appalling and disgusting as the challenges were, our initial inquiries suggest that of the small number of boys involved, many did not participate in the socially unacceptable or criminal activities."

Mr Zavone said while staff were as concerned about the poor choices of some students, they did not believe there was a culture of misogyny and risk-taking embedded in the school.

As recently as Thursday, year 12 students were involved in a workshop on the concept of right relationships as part of a series of workshops which began in year 9.

Earlier this year, Mr Zavone spoke to The Canberra Times about teaching young men about consent and respectful relationships in the wake of the rape allegation by former Liberal staffer Brittany Higgins and the harrowing testimonies from Sydney private school girls collected by former Kambala School student Chanel Contos.

He spoke of the College's efforts to involve parents in the conversation as well as the struggles to educate young men to make good decisions when they are exposed to pornography, drugs and alcohol.

Since the list of activities has come to light, Mr Zavone said staff would reflect on how they could improve education in this area.

"The existence and nature of the list, and the participation of some of our students with some of the elements of the list, clearly shows that we still have work to do to ensure that the message that we are trying to instil in our students is fully internalised."
