Inside the Woodville Gardens voting booth on Saturday morning, Peter Malinauskas cast his ballot as the country watched. Hours later, as polls closed and counting commenced, the early signals came through: Labor was poised for a landslide, and the map of South Australian politics had shifted in ways that nobody could have predicted four years ago.
Within an hour of polls closing, early projections from multiple polling organisations suggested a commanding victory for the incumbent Labor government. Yet beneath this headline lay a story of far greater consequence for national politics. One Nation had surged to second place in primary voting, placing it ahead of the Liberals for the first time, with particularly strong support in regional areas.
Malinauskas came to office in 2022 as a moderate voice in a Labor Party often beset by internal division at the federal level. He campaigned then on infrastructure, jobs, and economic management. Four years later, he heads into his second term with approval ratings that few political leaders ever achieve. A majority of 61 per cent of electors approved of the way Malinauskas was handling his job as Premier, compared to 37 per cent who disapproved. Malinauskas maintained a commanding lead as preferred Premier, ahead of Opposition Leader Ashton Hurn, 55 per cent to 22 per cent.
The polling suggested something unprecedented: Labor was on track for their largest two-party preferred vote in the South Australian Labor Party's history, whilst the Liberals were on track for their worst-ever result, finishing third on just 19 per cent. The last time a party won over 30 seats in a South Australian election was 1993 under Liberal Dean Brown. The question facing analysts heading into counting was not whether Labor would win, but how many seats they would claim.
The campaign itself revealed the fault lines reshaping conservative politics across the nation. One Nation surged in regional areas with anti-establishment messaging, immigration critiques and economic populism under Pauline Hanson's active involvement. The shift was not gradual. Polling conducted in the week before the election showed One Nation on 28 per cent, well ahead of the Liberal-National Party on 16.5 per cent, though both trailed Labor at 35 per cent on primary votes.
What strikes observers when they examine the numbers is not merely Labor's dominance, but the near-total collapse of Liberal support in the state. Only 55 per cent of those who voted Liberal in the last federal election intended to support the party at the state level, with 29 per cent now voting One Nation and 10 per cent Labor. This is not ordinary electoral churn. This is a rupture. Younger Liberal voters have drifted in multiple directions; older ones remain loyal. The Liberals lost every seat in Adelaide at the last federal election. That metropolitan wall, once solid, crumbled years ago.
One Nation's emergence as a genuine electoral force carries implications that extend far beyond Adelaide. If projections held, Labor could secure its largest two-party preferred vote ever, potentially challenging national landslide records. But the party's strength lies not in the metropolitan core where Labor dominates. It lies in the regional seats, the grain belts, the coastal towns where voters feel they have been forgotten. Support was strongest outside Adelaide, where One Nation led with 27 per cent, ahead of Labor at 24 per cent and the Liberals at 21 per cent.
Yet even as One Nation's primary vote soared, the mechanics of Australian preferential voting work against it. In regional areas, the contest became highly competitive with a three-candidate preferred split of Labor 38 per cent, One Nation 34 per cent, and Liberals 24 per cent. One Nation's voters, predominantly drawn from those who have abandoned the Coalition, will return many preferences to Liberal candidates in tight contests. In a system designed to deliver majorities, One Nation's surge in primary vote may not translate to proportional gains in seats.
The election nonetheless exposed something real: a wholesale rejection of orthodox conservative politics as practised in South Australia for decades. Whether that rejection stemmed from cost-of-living pressures, immigration concerns, or simple exhaustion with leadership instability matters less than the fact of the rejection itself. Ashton Hurn, just 35 years old and a first-term MP, had been left with under 100 days to restore the party's fortunes after taking over a Liberal opposition that had trailed Labor in the polls for four years. She was fighting an impossible tide.
As ballot papers continued through the counting machines on Saturday evening, the outcome was plain. Labor would govern South Australia for another four years. The real question Saturday's South Australian election would finally tell us was whether One Nation's rise was real. The answer, when the full count was done, would carry consequences that stretched far beyond the state boundaries.
