One Nation candidate David Farley won the Farrer by-election on May 10, 2026, securing a seat in the Australian House of Representatives [1].

The victory marks a historic shift in the Australian political landscape, as it is the first Lower House seat won by One Nation in federal parliament [3].

The result represents a significant blow to the Coalition. The Liberal Party suffered a swing of over 30 percent [1], leaving their final vote share at 12 percent [1]. The Australian described the result as a landslide that reduced the Coalition vote to rubble [1].

Farley attributed the win to a strategy of direct communication with the people of New South Wales. "The biggest thing, we were communicating with all the constituents right across Farrer," Farley said [4].

Analysts said the outcome was driven by a combination of clear messaging and strong local engagement [4]. The electorate in Farrer shifted decisively away from the traditional conservative base to support the One Nation platform during this contested race [2].

Farley's entry into the House of Representatives provides One Nation with a direct legislative voice in the lower chamber, a position the party has previously lacked despite its presence in the Senate.

The capture of a Lower House seat by One Nation signals a potential fracturing of the traditional conservative coalition in regional Australia. By reducing the Liberal vote to 12 percent in a former stronghold, this result suggests that populist messaging is currently outperforming established party loyalty in certain electorates, which may force the Coalition to pivot its policy focus to regain rural support.
