Jason Virgo is an Australian politician, and has represented the district of MacKillop in the South Australian House of Assembly since the 2026 state election. Virgo is a member of One Nation.
Virgo was twice a candidate for the Australian Sex Party, standing at the 2010 and 2013 federal elections for the party in the Senate. He was also a former secretary for the Mount Gambier branch of the Australian Labor Party. He has previously worked in immigration detention on Christmas Island.
Virgo stood for the Mount Gambier City Council in 2022, but was unsuccessful. However, when Ben Hood resigned from council in 2023 to take up a seat in the Legislative Council, Virgo was elected to Mount Gambier City Council via countback. Prior to this, Virgo worked at Mount Gambier Prison. As a councillor, Virgo called for the return of the Autofest motoring event to Mount Gambier, to provide an alternative to unsafe hooning on the roads.
Virgo was announced as the One Nation candidate for the MacKillop district at the 2026 state election, and took leave from council to focus on his candidacy. Following the 2026 state election, MacKillop remained in doubt for a number of days. While Nick McBride, the outgoing MP, had clearly been defeated, there was still a possibility that Virgo could be overtaken by Liberal candidate Rebekah Rosser. However, Virgo was ultimately successful, holding his lead against Rosser to become the new MP for MacKillop.
