Ian Douglas Trezise (born 30 September 1959) is an Australian politician. He was a Labor Party member of the Victorian Legislative Assembly from 1999 to 2014, representing the seat of Geelong.[1]
Trezise was born and raised in Geelong, the son of high-profile Labor minister and AFL footballer Neil Trezise,[2] and is of Cornish descent.[3] He was educated at Newcomb Primary and Geelong High School before completing a postgraduate diploma in personnel management. Ian worked for the Australian Workers' Union for a number of years, before becoming shipping manager at the Port of Geelong. He was a Geelong City Councillor from 1989 to 1993.[1] He is married with two children.
Trezise was first elected in 1999, when he won the seat of Geelong by a very narrow 16 votes, as part of the dramatic 1999 Victorian state election. In the 2002 election he substantially increased his majority with an 8.5% swing, and he maintained that vote in the 2006 state election. In the 2010 election his margin was slashed to 2.1%.[4]
He served on the parliamentary Road Safety Committee from 1999 until November 2010, and was chairman from 2003 to 2006.[1]
Trezise resigned as the Member for Geelong at the 2014 Victorian state election. He was succeeded by Christine Couzens, a member of his staff since he was elected in 1999.
