The Marist Brothers built this College to provide a Catholic Education to the boys of Eastern Metropolitan Melbourne. Marcellin College therefore has a very close association with local Catholic Parishes and associated Catholic Primary Schools in supporting the continued faith development of boys. This association strongly influences the Colleges enrolment criteria in that Catholic boys who live within the boundaries of the Colleges designated feeder parishes are given priority of entry. These parishes are:
