John Zammit is a psychologist and former Manus Island health worker.
After completing a Science degree and working a couple of years at Monash University, John entered a Catholic religious order intending to become a priest. During the next six years he was able to offer pastoral care, welcome and support to Vietnamese, Chilean and Timorese refugees at the Springvale Migrant Hostel. His interest in refugees continued after leaving religious life, as he studied Psychology and worked in various jobs with people from non English-speaking backgrounds. By 2013 John was employed by International Health and Medical Services (IHMS) , working as a counsellor on Manus Island and, for a short time, in Nauru.
