Background
The 2025 Western Australian state election saw Labor win one of the largest majorities of any state or territory government, despite losing some seats from the previous election.[3]
The Liberal Party barely regained opposition status from the National Party, with seven seats compared to the latter's six.
After the election, the leader of the Liberal Party leading to the 2025 state election, Libby Mettam resigned, citing that she did not have the support of her party room to continue as leader.[4] This triggered a leadership election, where Basil Zempilas, who was elected in the 2025 election, and the former Lord Mayor of Perth was elected leader unopposed, with Mettam being elected as the Deputy Leader unopposed.[5]
Electoral system
Candidates are elected to single-member seats in the Legislative Assembly via full-preferential instant-runoff voting. In the Legislative Council, MLCs are elected on a single statewide ballot by Single Transferable Vote. Votes are cast under a semi-optional preferential form of STV using above-the-line voting. It requires electors to mark preferences for one or more preferred parties above the dividing line on the ballot paper, or at least 20 candidates below the dividing line.
Key dates
Elections are scheduled for the second Saturday of March every four years, in line with legislative changes made in 2011.[6]
While the Legislative Assembly has fixed four-year terms, the Governor of Western Australia may still dissolve the Assembly and call an election early on the advice of the Premier.[7]
