First term Flint was elected to the
Australian House of Representatives for the seat of
Boothby in 2016, replacing retiring MP
Andrew Southcott, who had held the seat since 1996. In 2017, Flint bought 400 copies of a book published by the Menzies Research Centre, a Liberal Party think tank, spending $5818. This was more than any other politician spent on publications between July 2017 and June 2018, despite the book being available online for free. During the
2018 Liberal Party leadership spills, Flint was one of 43 party members to sign a petition calling for Prime Minister
Malcolm Turnbull to call for a second leadership spill.
2019 election In April 2018, the
Australian Electoral Commission rearranged the electoral boundaries of South Australia to reduce the number of seats from 11 to 10, in accordance with South Australia's shrinking percentage of the Australian population. The changes to the seat of Boothby resulted in Flint's 2016 margin of 3.5% shrinking to 2.8%. After the redistribution, Boothby was the only marginal seat in the state, making it a target for the
Australian Labor Party in the
2019 Australian federal election. Flint was also a target of the progressive activist group
GetUp, who labelled her South Australia's "most backwards politician". Days before the election, Flint's campaign office was vandalised with offensive graffiti. She faced further harassment during the campaign, with a man cautioned for allegedly stalking her and her office also being egged. The race was too close to call on the night of the election, but Flint was eventually declared the winner of the election. Whilst her first preference vote share increased by 3.5%, she suffered a negative swing of 1.3% in the two candidate preferred results. Following the election, Flint accused GetUp, Labor and
trade union supporters of being responsible for harassment, intimidation and stalking against her during the campaign, and Prime Minister
Scott Morrison labelled the actions as misogynistic and bullying.

Boothby. She lost to Miller-Frost on a large swing. == Political views ==
