28 of One Nation's 51 elected MPs have quit or been expelled
More than half of all One Nation MPs have left the party mid-term, yet the party now polls above 30% nationally.
Guardian analysis reveals a striking pattern in One Nation's three-decade history: 28 of 51 MPs elected under Pauline Hanson have either resigned or been expelled before their terms ended. In 1998, all 11 One Nation members in Queensland parliament soon either resigned from the party to sit as independents, or resigned from parliament altogether.
More recent turmoil includes senator Rod Culleton quitting then being disqualified, Fraser Anning replacing Roberts then quitting One Nation on his first day in parliament, and Brian Burston defecting to United Australia.
Despite this instability, One Nation won 6% nationally in 2025 and now polls above 30%, potentially enough to become the official opposition or hold the balance of power.

Why it mattersVoters backing One Nation at record levels should know the party has a proven track record of internal collapse and member departures, which could affect its ability to deliver on policy if it holds significant parliament seats.
AustraliaWith One Nation potentially becoming a major force in federal parliament, Australians are choosing a party whose own MPs have a history of leaving mid-term, raising questions about stability and follow-through.
