Susan Knowles

Susan Christine Knowles (born 10 April 1951) is an Australian former politician who served as a Senator for Western Australia from 1984 to 2005, representing the Liberal Party. She briefly served as a shadow minister under John Hewson from 1993 to 1994.

Early life Knowles was born in Brisbane, Queensland. She was the sales manager of a Perth office equipment company before entering politics. In 1979 she was appointed to the National Youth Advisory Group within the Department of Employment and Youth Affairs.

Political career Knowles served as state president of the Young Liberal Movement from 1977 to 1981. She later held various positions in the Liberal Party of Australia (Western Australian Division), including state executive member, state council member, vice-president, and senior vice-president. In August 1994 she publicly opposed new opposition leader Alexander Downer's decision to sack Hewson from the shadow ministry. Knowles later served as chair of the community affairs legislation committee from 1997 until her retirement in 2005.

In 1995, Knowles came into conflict with her Liberal colleague Noel Crichton-Browne over allegations that he had been violent towards his wife several years earlier. Knowles stated that she had helped shelter Crichton-Browne's wife at the time. The allegations came three days after Crichton-Browne was expelled from the Liberal Party. In June 1995, it was reported that Crichton-Browne was being investigated for making death threats towards Knowles. He denied that he had threatened her, stating that the allegations were "scurrilous, crude and filthy". Knowles initially did not comment, but in September confirmed that she had made a complaint to the Western Australia Police. In October 1998, she publicly retracted her statements and apologised to Crichton-Browne, as well as paying him a settlement of $20,000.

In 1999, the disciplinary committee of the WA Liberals voted to expel Knowles from the party over unnamed complaints, apparently due to the continued influence of Crichton-Browne. In March 2003, Knowles announced that she would not re-contest her seat at the next federal election. Her term ended on 30 June 2005. She has served on the Ad Standards Community Panel since December 2017.
