A Crushing Victory Amid Political Realignment

South Australia stands at a critical juncture as Premier Peter Malinauskas's Labor government prepares for what polls suggest will be a decisive electoral victory in approximately one month. However, beneath the surface of Labor's commanding 59-41 percent two-party preferred lead lies a more complex and potentially transformative political story: the dramatic rise of One Nation and the near-collapse of the Liberal Party.

The Current Political Landscape

According to multiple sources (Articles 1-20), Premier Malinauskas launched Labor's re-election campaign on February 22, 2026, with a clear strategic message framing the election as a choice between "optimism and opportunity" versus "division and discord." The Premier's campaign emphasizes major policy achievements including housing plans and the multibillion-dollar nuclear submarine industry, repeating the word "opportunity" more than a dozen times in his launch speech (Article 8). The most striking aspect of the current polling is not just Labor's dominance, but the potential "near-wipeout" facing the Liberal Party, which could see them "eclipsed by the anti-immigration One Nation" party (Articles 1-20). This represents a fundamental realignment of South Australian politics, with implications that extend beyond state boundaries.

Key Trends and Signals

### 1. The One Nation Surge The articles consistently emphasize that One Nation's rise is occurring "both in the state and nationally" (Articles 1-20), suggesting this is not merely a local phenomenon but part of a broader shift in Australian politics. The Premier's explicit acknowledgment of this threat—dedicating significant portions of his campaign launch to addressing it—indicates Labor internally views One Nation as the primary opposition force, not the Liberals. ### 2. Liberal Party Collapse The potential for the Liberal Party to be eclipsed by One Nation would be unprecedented in South Australian politics. This collapse appears to be driven by a combination of factors: Labor's strong performance in government, voter dissatisfaction with traditional parties, and One Nation's success in capturing protest votes and anti-immigration sentiment. ### 3. Labor's Strategic Positioning Malinauskas's campaign framing is notably sophisticated. Rather than ignoring One Nation or attacking them directly, he's attempting to position Labor as the bulwark against divisive politics, making the election about "the kind of politics we want in this state, even in this country" (Articles 1-20). This elevates the stakes beyond typical state issues.

Predictions: What Happens Next

### Near-Term Electoral Outcome (March 2026) Labor will secure a crushing victory, likely increasing their majority in the South Australian Parliament. The 59-41 two-party preferred polling is remarkably strong and consistent across all reporting, suggesting Labor will win comfortably. However, the composition of the opposition will be the story that defines this election. ### One Nation's Breakthrough One Nation will likely secure their best-ever result in South Australian state politics, potentially winning multiple lower house seats and significantly increasing their presence in the Legislative Council. The consistent emphasis across all articles on their "surge" and potential to eclipse the Liberals suggests this is not media speculation but a reality reflected in internal party polling and seat-by-seat analysis. ### Liberal Party Crisis The Liberal Party faces an existential crisis. Even if they narrowly avoid being eclipsed by One Nation in total seats or vote share, the psychological and organizational impact of finishing third in any meaningful metric will trigger internal turmoil. Expect leadership challenges, factional warfare, and potentially defections to either One Nation or independent status in the months following the election. ### National Implications Malinauskas's explicit framing of this as a national issue ("even in this country") signals Labor's intention to use a South Australian victory as a template for federal messaging. The success or failure of his "optimism versus division" framing will be closely watched by federal Labor strategists as they prepare for future federal campaigns. ### Post-Election Governance Challenges While Labor will have the numbers to govern comfortably, they will face a more fractious and unpredictable parliament with One Nation holding significant influence. This could complicate passage of legislation and force Labor to engage with populist policy positions they might prefer to ignore.

The Broader Context

This election occurs against the backdrop of global trends toward political polarization and the rise of right-wing populist parties. South Australia's experience may preview similar realignments in other Australian states and territories. The nuclear submarine project mentioned in Malinauskas's campaign (Articles 1-20) represents both economic opportunity and potential controversy, particularly around environmental and strategic concerns that One Nation may seek to exploit.

Conclusion

The South Australian election will deliver Labor a substantial victory, but the real story will be the political realignment occurring on the right. One Nation's rise represents a fundamental challenge to traditional two-party politics in Australia, and how this plays out in South Australia will influence political dynamics nationally for years to come. The Liberal Party's capacity to respond and rebuild—or whether they face terminal decline in favor of new political movements—will be the defining political question of the next parliamentary term.
