Recent Coalition internal tensions and One Nation’s electoral gains have shaped trader views on further defections. Nationals MP Colin Boyce publicly indicated in May 2026 that he was weighing a switch after the Coalition’s primary vote collapsed in the Farrer byelection, building on Barnaby Joyce’s December 2025 move from the Nationals that gave the party its first House seat. One Nation has posted stronger polling and state-level advances since the 2025 federal election, creating openings for disaffected Coalition members. These signals of party-room friction are balanced against the absence of additional confirmed switches so far and the short remaining window through December 2026, supporting the 58 percent implied probability of at least one more sitting MP joining.
