One Nation sees over half of its elected MPs quit or be expelled

A review of One Nation’s parliamentary record shows that 28 of the 51 MPs and senators elected under Pauline Hanson’s banner have exited the party before completing their terms, either by resignation or expulsion. The party, which earned 6% of the vote in the 2025 federal election, is now polling above 30% in certain surveys, suggesting potential for a larger parliamentary role. Its history is marked by repeated upheavals: the 1998 Queensland win followed by mass resignations, the 2016 federal double-dissolution election that brought four senators, and a series of subsequent departures including Rod Culleton, Malcolm Roberts, Fraser Anning and Brian Burston.

Notable former members such as Mark Latham, Tania Mihailuk, and long-serving Rosa Lee Long have also left. Recent growth includes David Farley’s lower-house victory in the Farrer by-election, joining former Nationals deputy Barnaby Joyce in parliament, yet the party’s internal volatility persists.
