One Nation Beats Liberals in South Australia With 21 Per Cent of the Primary Vote
Pauline Hanson's party becomes second-highest polling party in SA but preferential voting limits seat gains
The result represents the most significant electoral breakthrough for Pauline Hanson's party since its founding, surpassing the Liberals in raw vote share and sending what one analyst called "a shiver through the Liberal Party" nationally.
However, the headline number tells only part of the story. Despite the remarkable primary vote, One Nation's lower house seat count remains slight. Australia's preferential voting system means that a broadly distributed vote — even a large one — does not necessarily translate into seats, which require concentrated support in individual electorates.
The result has drawn more national attention to the undercard fight within the right of Australian politics, with the Liberal Party left deeply wounded by the scale of One Nation's vote. Questions are now being asked about whether the Liberals' strategy of trying to hold the centre-right is sustainable when a significant chunk of their base is willing to defect to a populist alternative.
Analysis
Why This Matters
This is a watershed moment for minor party politics in Australia. A 21 per cent statewide primary vote is extraordinary for any party outside the two major blocs, and it suggests deep dissatisfaction with the Liberal Party among conservative voters.
Background
One Nation has historically performed well in Queensland and parts of regional Australia but has struggled to break through in southern states. South Australia's unique political landscape — with a strong independent tradition — appears to have created fertile ground.
Key Perspectives
The gap between votes and seats highlights both the strength and limitation of preferential voting. One Nation's support is broad but not deep enough in individual seats to win them outright. For the Liberals, the question is existential: do they move right to recapture these voters, or hold the centre and risk further bleeding?
What to Watch
Whether One Nation can convert this vote share into actual seats as counting continues, and whether the result accelerates a realignment on the Australian right ahead of the next federal election.
