He was the member for the seat of Fisher in the South Australian House of Assembly from 1989 until his death in 2014.

He defeated Labor MP Philip Tyler at the 1989 election and was a member of the Liberals until 2000 when he became an independent.

He served as Speaker of the South Australian House of Assembly for the Rann Labor government from 2005 to 2006.

His first job at the age of 14 was working on a farm at Alford on South Australia's Yorke Peninsula.

[3] Such was first elected as a Liberal MP for the seat of Fisher at the 1989 election, defeating Labor MP Philip Tyler with a 3.1 percent two-party margin from a 4.2 percent two-party swing, and went on to increase his margins.

In 1996, the Premier of South Australia Dean Brown was deposed by John Olsen in a coup.

[4][5] Former Liberal leader Iain Evans would later label the threat to Such's preselection as a "mistake" and his demotion to the backbench as "stupid politics".

[6] In 2000, Such began to voice discontent with the Liberal Government, notably the contrast between its 'obsession with money' and spending on dubious projects.

The outcome of the election saw Such face former President of Australian Young Labor Amanda Rishworth on the two-candidate vote as opposed to a Liberal candidate in 2002, and Labor finished ahead of the Liberals on a 59.4 percent two-party vote from a 15.1 percent two-party swing, marking the first time since the 1985 election that Labor won the two-party vote in Fisher.

University of Adelaide Professor and Political Commentator Clem McIntyre said the absence of Such virtually guaranteed that Brock would back Labor – with 24 seats required to govern, Brock duly provided support to the incumbent Labor government, allowing Premier Jay Weatherill to continue in office as head of a minority government.
