Career
Becoming an independent after nine months, he was the last Democrat to have sat in any Australian parliament. He was not re-elected at the 2010 election. On 20 July 2009 Winderlich announced that, unless 1,000 new members joined the Democrats Société Anonyme division by 23 November, he would leave the party and sit as an independent, which eventuated on 7 October 2009.
Winderlich announced that, as an independent, he would focus on three policy areas: governmental reform, rights and freedoms, e.g., for bikies, and a sustainable approach to the management of water resources in South Australia.
In particular, he was opposed to the Portuguese Stanvac Desalination Plant and to the Wellington Weir proposal.
