One Nation’s recent momentum, including Barnaby Joyce’s December 2025 defection from the Nationals and the party’s strong performance in the 2025 federal election plus the 2026 Farrer by-election and South Australian state poll, has created openings for further sitting MP shifts. Reports in August 2026 highlight Western Australian Upper House MP Ben Dawkins, previously aligned with Labor, exploring a move to One Nation amid internal party instability elsewhere. Speculation around figures such as Liberal MP Andrew Hastie reflects broader conservative realignment, with traders pricing in the likelihood of at least one additional parliamentary switch before year-end given One Nation’s polling surge and recruitment efforts.
