Candidate Ashton Hurn

Incumbent Leader Vincent Tarzia

The 2025 South Australian Liberal Party leadership election will be held on 8 December 2025 to elect a new leader of the South Australian Liberal Party and Leader of the Opposition in South Australia.

Vincent Tarzia announced via a press release that he would step down at 17:00 SA time on 5 December 2025. ^[1]

This resignation came less than 100 days before early voting was to begin for the 2026 South Australian state election, and was the fourth Liberal leader to either be ousted or resign in a month, following the resignations of Leanne Castley in Canberra and Mark Speakman in New South Wales, as well as the defeat of Brad Battin in the 2025 Victorian Liberal Party leadership spill, each of these being replaced respectively by Mark Parton, Kellie Sloane and Jess Wilson, the latter two being first-term MLAs.
