2023 Perth City Council election

The previous mayoral election was held in October 2020, following the council's suspension by the Western Australian state government in 2018.^[1] Four of the eight councillors elected in 2020 faced another election in 2021, while the remaining four had their terms expire in 2023.^[2]

Three candidates contended the position of Lord Mayor − incumbent Basil Zempilas, councillor Sandy Anghie (who also contested the 2020 election) and Will Leyland.^[3]

The campaign was surrounded by claims that Zempilas would join the Western Australian Liberal Party and contest the 2025 state election. On 6 September 2023, Zempilas confirmed he would seek re-election.^[3] Anghie campaigned on "serving full time for a full term," and said she did not have ambitions for state or federal politics.^[4]

The Greens endorsed one candidate − Isabella Tripp − who also ran in Cowan at the 2022 federal election.^[5][6]

Electoral reform introduced into the state parliament by the McGowan government in February 2023 saw optional preferential voting (used for state and some local elections in New South Wales) introduced, replacing first-past-the-post.^[7]
