Paul Trezise was born and raised in Melbourne. Involvement in the early development of the sport of Orienteering in Victoria led him to develop an interest in the spatial sciences and he subsequently completed a Bachelor of Surveying at the University of Melbourne. After three years working as a Surveyor in private practice in Melbourne he unexpectedly found himself moving to Canberra in 1982 after joining the Commonwealth’s national topographic mapping agency. There he was able to develop his interest in digital cartography using all the latest technology that only the federal government could afford. At the same time he joined the St Vincent de Paul Society as a volunteer member of a Conference responsible for managing the Monica House refuge for women and children in Narrabundah. He found this an interesting and rewarding experience.
Paul worked in various roles in the Commonwealth Public Service for 30 years. Highlights included a year working at the Ordnance Survey in the UK, managing the national topographic mapping program and managing Australia’s primary facility for reception and processing of satellite data, the Australian Centre for Remote Sensing. In 2001 he joined Geoscience Australia as Chief Information Officer and continued working there in various senior management roles prior to re-joining the St Vincent de Paul Society as its Canberra/Goulburn CEO in February 2012.
