Labor could suffer a double-digit swing and lose more than 10 seats at Saturday’s state election in Western Australia, and it would still be the party’s second-best result in history.

The dominance of WA Labor – achieved at the last election in 2021 on the back of isolationist pandemic policies that proved extremely popular – set a high-water mark that is unlikely to be repeated. The party heads to the polls with 53 of 59 lower house seats.
