With nearly all votes counted in Saturday’s Western Australian state byelection for Secret Harbour, the ABC’s results give One Nation 39.1% of the primary vote (up a huge 30.6% since the March 2025 state election), Labor 24.4% (down 22.1%), the Liberals 17.3% (down 7.1%), the Greens 7.5% (down 1.3%), Legalise Cannabis 3.7% (down 2.1%), Animal Justice 1.8% (down 0.8%) and Australian Christians 1.7% (down 1.1%).
A surprisingly weak flow of preferences to One Nation has restricted their winning margin after preferences to 57.0–43.0 against Labor. But it is still a thumping victory, compared with Labor’s 61.5–38.5 win over the Liberals in 2025. Although the Liberals had more than double the Greens’ vote, preferences favoured Labor by 50.8–49.2 over One Nation.
