Reynolds operated her own business and taught community development at TAFE before entering politics. She was the Democrats candidate for the safe Liberal seat of Schubert at the 2002 state election, polling a credible 8.9% of the vote. She received a second opportunity a year later when she was selected by the party to fill a casual vacancy in the Legislative Council caused by the resignation from politics of then-Democrats leader Mike Elliott.
During her time as a sitting member Reynolds spoke out on a range of issues including the treatment of asylum seekers at the controversial Baxter Detention Centre in South Australia’s outback, and campaigned for increased social housing for disadvantaged people and increased funds for child protection and for people with disabilities. She also campaigned for equal rights before the law for same sex couples and sought to have South Australia’s once ground breaking Equal Opportunity law updated.
Reynolds was described by Greg Kelton, the senior political writer with Adelaide’s only daily newspaper as having “a finely tuned social conscience and has not been scared to tackle humanitarian issues such as refugees and asylum seekers”.
The popularity of the Democrats had dropped significantly by the time of the 2006 election, with the party having lost all four senators up for re-election at the federal election in 2004. The retirement of fellow Democrat MLC Ian Gilfillan saw Reynolds preselected in the top position of the Democrat ticket, but the party faced a major struggle to retain even one seat. The party's vote dropped from 7.3% to 1.8% on election day, and Reynolds duly lost her seat. The loss of both the party's seats up for re-election saw Sandra Kanck become the only remaining Democrat MLC in the Legislative Council.
Reynolds is currently is a board member of Arts Access SA Inc. and is a member of the South Australian Council of Social Service, the Australian Local Government Women’s Association SA Branch Inc. and the Commonwealth Parliamentary Association. Reynolds now works as an Independent Contractor in the areas of organisational development and community based education and training and is an Associate Consultant with Jarrah HR Consulting.
