David Farley of One Nation won the Farrer federal by-election on May 9, 2026, securing the party's first seat in the House of Representatives [1], [4].
The victory marks a significant shift in Australian politics by breaking the Liberal Party's long-term dominance in regional New South Wales. It signals a growing volatility among conservative voters and provides One Nation with a direct legislative foothold in the lower house for the first time [1], [2].
Farley defeated the Liberal Party incumbent in the Division of Farrer, a seat the Liberal Party had held for 77 years [2]. The result followed a massive collapse in support for the incumbent party, with the Liberal vote falling by more than 30 percentage points [3].
This electoral swing was driven by disenchanted conservative voters moving away from the Liberal Party [5]. The breakthrough provides One Nation with a strategic platform to challenge established parties in other regional areas, potentially replicating this success in Victoria and other federal contests [5].
The by-election results, finalized on Saturday night, confirm Farley as the first One Nation candidate to be directly elected to the lower house [1]. While the party has previously held influence in the Senate, this win allows the party to represent a specific geographic constituency in the House of Representatives [1].
Local observers said that the scale of the Liberal Party's losses reflects a deeper disconnect between the party leadership and its traditional rural base [3], [5].
“One Nation won the Farrer federal by-election, securing its first lower-house seat in Australian parliament”
The victory in Farrer transforms One Nation from a party primarily reliant on the proportional representation of the Senate to a direct competitor in the House of Representatives. By capturing a seat held by the Liberal Party for nearly eight decades, the party has demonstrated that a significant portion of the conservative base is willing to abandon traditional parties for populist alternatives. This creates a precarious environment for the Liberal Party in regional Australia ahead of future general elections.
