One Nation’s momentum after the 2025 federal election and its Farrer by-election win has kept defection talk alive inside the Coalition, producing the current 65 percent trader consensus. Barnaby Joyce’s December 2025 switch from the Nationals established a recent precedent for lower-house members crossing to the party. In May 2026 Nationals MP Colin Boyce publicly floated the possibility after the Coalition’s primary vote collapsed in Farrer, although he later ruled out a move. Persistent Coalition primary weakness, One Nation’s stronger polling in several states, and internal friction over policy direction continue to sustain speculation that at least one additional sitting MP could switch before year-end, even as no confirmed announcement has occurred since Joyce.
