The rise of One Nation in South Australia: a political earthquake for traditional parties

The right-wing populist One Nation party, led by Pauline Hanson, made a significant electoral breakthrough in South Australia, securing around 20% of the vote. This performance, while not yet translating into many seats, signals growing discontent with the major parties and could reshape Australia's political landscape.Breaking News, International, Policy, Legislative Assembly, South Australia, elections, political discontent, One Nation, right-wing party, Pauline Hanson, populism, electoral system, primary vote, AFE PACKAGE, newsThe right-wing populist One Nation party, led by Pauline Hanson, made a significant electoral breakthrough in South Australia, securing around 20% of the...
L'ascension de One Nation en Australie-Méridionale : un séisme politique pour les partis traditionnels

The South Australian election delivered a surprising result this weekend, with Pauline Hanson's One Nation party capturing almost a fifth of the vote. This performance, announced on March 21, 2026, marks a comeback for this populist formation, long marginalized, and questions the future of traditional parties in the region.

Despite scoring high in primary votes, One Nation has so far only won one seat in the Legislative Assembly, with the possibility of winning three more. This discrepancy can be explained by the state's proportional electoral system, which favors parties that are well established locally, while support for Hanson remains more diffuse.

Pauline Hanson, a former fish and chip shop owner turned controversial figure, capitalized on voters' frustrations. His anti-immigration speeches and populist rhetoric resonate particularly with a part of the population tired of the policies of the major parties, perceived as distant from daily concerns.

At a rally in Adelaide, Hanson delivered a stinging message to the outgoing prime minister, saying she would “leave him landmines”. This war metaphor illustrates his strategy of destabilizing the established political system, while galvanizing his supporters, who fervently acclaim him.

This electoral breakthrough comes against a backdrop of growing polarization in Australia, where issues of immigration, economic security and national identity divide the electorate. One Nation is taking advantage of this atmosphere to expand its influence, notably by collaborating with candidates like Cory Bernardi for legislative campaigns.

Political analysts see this result as a “worrying sign” for the major parties, which could be forced to review their strategies. In South Australia, Hanson's rise could further fragment the political landscape, making government formation more complex and unstable.

Beyond state borders, this development reflects a broader trend observed in other democracies, where populist movements are gaining ground against traditional elites. In Australia, this could influence national debates on topics such as electoral reform or social policies.

While the final results are still being compiled, one thing is certain: the success of One Nation in South Australia has sent shockwaves across the country. It remains to be seen how the established parties will respond to this challenge, which could reshape Australian politics in the years to come.
