@mickban; the decision to make boys apologise on behalf of their gender to female peers at a school assembly at Brauer College was a very bad one indeed and fortunately, a very rare event at Victorian public schools.
My guess is that the Principal will have a 'Please Explain' which may well lead to internal disciplinary action and subsequent 'counselling'.
Given that it's already happened, how the school now manages the issue of gender relations and sex education will be very important.
