Pauline Hanson's One Nation is preparing to expand its political influence into Western Sydney after securing a landmark victory in the federal by-election for Farrer. The result saw candidate David Farley claim the party’s first-ever seat in Australia’s House of Representatives, ending more than seven decades of dominance by the Liberal and National parties in the electorate. Party MP Barnaby Joyce, who left the National Party of Australia to join One Nation in 2025, said the success in Farrer demonstrated growing voter dissatisfaction with the major parties and marked the beginning of a broader strategy to challenge both Labor and the Coalition in key suburban and regional seats. Joyce said party officials were already speaking with potential candidates in Western Sydney, where they believe cost-of-living pressures and concerns over government policy are creating strong support for alternative political movements. The Farrer victory follows One Nation’s strong performance in the recent 2026 South Australian state election, where the party won four seats and outpolled the Coalition. Joyce said One Nation intends to “go for government” and expand beyond its traditional protest-vote base, while ruling out any formal coalition agreement with the Liberal and National parties. Instead, he said the party would consider offering support and confidence to a minority government in exchange for policy concessions. Joyce also cautioned Coalition MPs considering defection that joining One Nation would not be automatic, emphasizing that the party would selectively determine who aligns with its long-term vision. His remarks followed reports that Colin Boyce was contemplating a switch after the Coalition’s vote in Farrer collapsed to just 22 per cent. Political analysts say One Nation’s strategy reflects a significant shift in Australia’s political landscape, with the party seeking to transform itself from a fringe force into a serious national contender. The outcome in Farrer and the focus on Western Sydney suggest that One Nation is targeting both regional dissatisfaction and suburban discontent as it attempts to reshape the balance of power in federal politics.
