Greg Wilton

Wilton's marriage broke down in early 2000, and rumours began to surface that he would soon resign. Then Wilton was found by police, distressed in a car with his two young children in the You Yangs, near Geelong as he was driving out of the national park. While the circumstances of the incident were never clear – fellow MP Kelvin Thomson said that Wilton had told him that he would never have harmed his children – it was reported by the media as an attempted murder-suicide.

On 14 June 2000, Wilton took his own life in a national park near the town of Labertouche, in the Shire of Buln Buln. His death sparked a major reaction, with the media, the Labor Party, and the family law and mental health systems all coming in for some blame in the ensuing days. Many also pointed to the Australian political tradition of voluble, even personal, politics. The Australian Press Council came under fire for not having guidelines as to the reporting of attempted suicide.

Wilton's seat was filled by the Australian Labor Party's Ann Corcoran at a by-election on 12 August 2000.

He won pre-selection to contest the Liberal-held marginal seat of Isaacs in the leadup to the 1996 election. Though his party lost government at the election, Wilton won the seat, aided by boundary changes which turned it into a marginal Labor seat, defeating sitting member Rod Atkinson. He remained on the backbenches once in parliament, and served on the Financial Institutions and Public Administration Committee for all of his four years in parliament. Wilton became a very well known and highly regarded local MP, although he was not a major player on the national stage.

Wilton was also active in politics for many years, having joined the Australian Labor Party in 1982. He served as the president and secretary of his local branch from 1982 until 1984, and as a delegate to the party's state conference from 1984 to 1992.

Wilton was born in Melbourne, raised in suburban Chelsea and studied at Monash University, where he obtained a Bachelor of Science. Later, he went on to study at the London School of Economics. Wilton spent most of 1980–81 touring and making friends in North America. He worked as an industrial officer for most of his working career, with the Australian Services Union, National Union of Workers and Association of Professional Engineers, Scientists and Managers, Australia, resigning from the latter upon his election to parliament in 1996.

Gregory Stuart Wilton (6 November 1955 – 14 June 2000) was an Australian politician. He was a member of the Australian House of Representatives, representing the Division of Isaacs, from 1996 until his suicide at the age of 44. He is the only serving member of the House of Representatives to have committed suicide.
