This was Labor's third consecutive landslide victory since winning government in 2017 and Labor's second best result after the previous 2021 state election. Labor won 46 seats in the lower house, a decrease of seven seats from their 2021 result. The Liberal Party won 7 seats while the National Party won 6, ensuring that the Liberals returned to official opposition status in the parliament.[4] Labor's primary vote fell by over 18 points to 41.4%, while the Liberal vote increased by more than six and a half percent to 28% and the National vote was 5.2% (up 1.2%).
Candidates were elected in single-member seats in the Legislative Assembly via full-preferential instant-runoff voting. In the Legislative Council, 37 candidates were elected using single transferable voting across the state, which functioned as a single electorate. Amendments made to electoral law had increased the size of the Legislative Council by one member at this election and also had abolished the former system of six regions of unequal population that each elected six members using single transferable voting.
In September 2021, the McGowan Labor Government introduced the "one vote, one value" legislation to change the voting system for the Legislative Council at this election. Under the then-existing voting system for the upper house, which had been in place since 2005, voters were divided into six regions of unequal weight, each of whom were responsible for electing six candidates (36 in total). Three of the regions were based in metropolitan Perth, and three in the regions. This meant that the Mining and Pastoral region had as many voters as only 16% of the number of electors in the three metropolitan regions on average.[13][14] The government first proposed abolishing the regions and replacing them with what it called a "one vote, one value" system.
Instead, 37 members were elected from a single statewide constituency using single transferable voting (STV). This increased the size of the council by one seat. Group voting tickets (GVTs) were abolished. GVTs were abolished for the federal Senate in 2016 and, at the time of this election, were only used for the Victorian Legislative Council.[15] Votes were cast under a semi-optional preferential form of STV using above-the-line voting. It required electors to vote for one or more preferred parties above the dividing line on the ballot paper, or at least 20 candidates below the dividing line. The legislation passed the parliament on 17 November 2021 and received royal assent seven days thereafter.[16][17]
The election of 37 members for the Legislative Council constitutes the largest district magnitude seen in STV any time in history.
According to psephologist Antony Green, the Coalition will need a combined swing of 23.4% to gain the 24 seats needed to form a majority government.[18]
On the new boundaries, there are 17 seats with margins under 15%, which will be regarded as "key seats". (Green described these as "marginal seats" due to the extent of Labor's landslide in 2021, as normally a margin of over 15% would be considered a safe seat.)

Key dates
Elections are scheduled for the second Saturday of March every four years, in line with legislative changes made in 2011.[19]
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.[20]
