The initiation in September last year attracted hundreds of students to the backyard of a flat on the corner of Cumberland and Dundas Sts. Nine first-year students had their heads shaved, stripped down to their underwear and sculled alcohol until they vomited.
Those nine were referred to the provost for their involvement in the initiation and were given final warnings.
They were required to complete 40 hours of community service after peer pressure from the older students - the nine subsequently excluded for this semester - was deemed a significant factor in their offending.
Despite the concerns about the flat initiations, the number of students referred to the proctor's office last year remained steady at 483.
Of the 41 students referred to the provost last year, 26 were referred for breaches of the university's code of student conduct which occurred during flat initiation events.
Eight other students who ran flat initiations involving excessive consumption of alcohol which jeopardised the health of other students were given suspended exclusions for the second semester this year.
The students are still able to attend university and might have their exclusions lifted if they complete 40 hours of community service, attend a meeting with vice-chancellor Prof Harlene Hayne about their behaviour and meet ongoing expectations of good behaviour.
Scott said he made no apologies for addressing student initiations, which in many cases were morphing from safe to harmful and unlawful.
