Career
Originally from Redan, Victoria, Trezise played 185 games for 272 goals between 1949 and 1959 at the Geelong Football Club in the VFL, playing in the 1951 and 1952 premiership sides. Following his retirement in 1959 (a year in which he was Geelong captain), Trezise continued his service to the club, coaching the reserves side and then becoming club president in 1974. Commonly called "Nipper", Trezise acquired the nickname as a young recruit at Geelong.
After leaving football, Trezise pursued a political career with the Australian Labor Party.
In 1982 he became Minister for Youth, Sport and Recreation (from 1985 just Minister for Sport and Recreation), a portfolio he held until 1992—throughout the entire terms of Premiers John Cain and Joan Kirner. Trezise died of a heart attack on 20 August 2006, with his funeral held on 24 August.
