One Nation won the Farrer byelection with candidate David Farley easily defeating independent Michelle Milthorpe in a seat previously held by former opposition leader Sussan Ley. The victory marks One Nation's first lower house seat at an election and reflects a substantial collapse in the Coalition vote, prompting Liberal leadership to acknowledge the result will prompt 'hard lessons' and sparking One Nation leader Pauline Hanson to declare the party will target additional Coalition and Labor seats nationally.
