St Peter’s has a very active social justice program with a dual focus on awareness and action. The student leaders lead the student body in a variety of initiatives including the Lenten CARITAS Appeal, St Vincent De Paul Appeals and Catholic Mission. Each year features a performance by Richard Cootes from Catholic Mission. The school encourages the students to propose other areas for social justice work at a local level and the emphasis changes from year to year in response to the needs of the local community.
In the past the community has supported “Bucks for Bales”, the Mark Hughes Foundation, Catholic schools in Vietnam and a variety of other more localised causes. St Peter’s stuednts also visits local aged care facilities to sing carols and spread some Christmas cheer.
