PEER SUPPORT LEADERS | Congratulations to this impressive group of Year 9 students who received certificates at assembly yesterday to mark their completion of Peer Support Program training.![]()
As Peer Support Leaders, they will work with small groups of younger students for the coming year, such as our new Year 7s.![]()
In preparation for this important role, their intensive training explored four key concepts: resilience, sense of self, connectedness, and sense of possibility.![]()
They are looking forward to using their new skills to support and welcome our incoming Year 7 2026 students at their Orientation Day next week and can’t wait to meet you all! Watch out for these friendly faces at the 'fruity' registration desks!
