The 2021 Western Australian state election is scheduled for Saturday 13 March 2021 to elect members to the Parliament of Western Australia, where all 59 seats in the Legislative Assembly and all 36 seats in the Legislative Council will be up for election. The first term incumbent Labor government, currently led by Premier Mark McGowan, will seek a second four-year term against the Liberal opposition, currently led by Opposition Leader Liza Harvey.
The 2017 state election saw Labor win one of the most comprehensive victories on record at the state or territory level in Australia. Labor won 41 of the 59 seats in the Legislative Assembly—a 23-seat majority—both WA Labor's strongest result ever, and the largest government seat tally and largest government majority in Western Australian parliamentary history. Additionally, Labor exceeded all published opinion polling, winning 55.5 percent of the two-party-preferred vote from a state record landslide 12.8 percent two-party swing.
Labor also became the largest party in the Legislative Council with 14 of the 36 seats. The Labor government will require at least five additional votes from non-government members to pass legislation.
Election dates are set in statute with four-year fixed terms, to be held on the second Saturday of March every four years.
