The Secret Harbour by-election in Western Australia concluded with a historic victory for One Nation, marking the party’s first seat in the Western Australian lower house. Candidate Luke Herdegen secured the seat, capturing 38.9 per cent of the primary vote and 57 per cent of the two-party preferred vote. This represents a significant rise from the party’s 8.43 per cent support in the March 2025 state election. The election, triggered by the retirement of senior minister Paul Papalia, resulted in a sharp decline for the Labor Party, whose primary vote dropped from 46.5 per cent to 24.3 per cent. Premier Roger Cook acknowledged the outcome as a signal that voters are struggling with high living costs, including unaffordable housing, high rents, and stagnant wages. Following the victory, Herdegen suggested that One Nation would aim to form government at the next state election, a claim Premier Cook dismissed as hubris. Liberal leader Basil Zempilas defended his party’s strategy, arguing that Liberal preferences were instrumental in delivering the One Nation win. The result has drawn sharp criticism from federal leaders. Federal Prime Minister Anthony Albanese described the party as ‘dangerous’, which prompted One Nation leader Pauline Hanson to accuse the Prime Minister of inciting political violence. Analysts suggest the win reflects a growing populist momentum and a protest against establishment politics that may impact future state and federal elections. In the wake of the political shift, real estate data indicates that median house prices in Secret Harbour reached $1 million in August, a 2.8 per cent increase over the previous month. ~~The suburb was noted as being among~~ Following the ~~top five areas~~ by-election, One Nation has experienced a significant surge in ~~the region for median house sale price growth during that period.~~ federal polling.
