Thumping Mandate for Hanson’s Movement
One Nation has delivered a resounding rebuke to Australia’s political establishment, securing a commanding victory in the Secret Harbour by-election that underscores growing voter disillusionment with mainstream parties. Luke Herdegen comfortably defeated Labor’s Georgia Tree in the Perth southern suburbs seat, a result that party leader Pauline Hanson wasted no time in interpreting as validation of her movement’s national momentum.
The scale of the shift was staggering—polling indicated a swing of over 20% against Labor in the beachside electorate, with One Nation’s WA leader Rod Caddies declaring that no Labor seat remained safe anywhere in the state or country. Even Nationals defector Barnaby Joyce suggested the political landscape had fundamentally shifted in favour of Hanson’s insurgent force, arguing that national polling was understating their true support levels.
Policy Confusion Fails to Derail Momentum
Despite a tumultuous week in which One Nation candidates struggled repeatedly to articulate coherent policy positions, voter backing for the party held firm. The chaos began when Farrer MP David Farley failed to clarify the source of proposed cuts to net overseas migration during a television appearance, setting off a cascade of confused explanations from Hanson and Joyce about what Farley had actually intended to convey.

The party’s strategist James Ashby even appeared on News 24 after dark brandishing a mop, acknowledging that “a clean-up job was required” following the policy missteps. Yet these gaffes appeared to have little impact on voters, suggesting that economic anxiety and cultural frustration are overriding traditional concerns about policy competence.
The result validates Hanson’s narrative that voters are increasingly willing to punish establishment parties regardless of their ideological alignment—a dynamic that threatens both Labor and the Coalition alike.
Opposition Leadership Under Scrutiny
The by-election defeat has left Western Australia’s Liberal opposition reeling, with state leader Basil Zempilas struggling to mount an effective response. His best defence amounted to complaining that the by-election would have favoured Liberal candidates had it been held in a seat closer to Perth’s CBD—a weak excuse that failed to address the underlying voter sentiment.
Federal Liberal frontbencher Andrew Hastie, whose Canning electorate encompasses Secret Harbour, recognised the gravity of the situation. His criticism of the state Liberal campaign proved prescient, though his personal history with One Nation—stemming from his testimony against Ben Roberts-Smith—adds an additional layer of complexity to the political dynamics at play.
Opposition leader Angus Taylor faces mounting pressure to adopt a more robust strategy against Hanson’s movement, moving beyond cautious preference negotiations to directly confront the populist challenge with clear conservative alternatives.
Implications for 2028 Federal Election
With more than a year remaining before the next federal election, the Secret Harbour result serves as a stark warning to incumbent MPs across all parties. Unless significant shifts occur in voter sentiment, politicians from Labor, Liberal, and National ranks should prepare for continued pressure from One Nation’s base.

Prime Minister Anthony Albanese’s recent speech to Queensland Labor members emphasised the party’s commitment to defending democratic institutions against what he characterised as “dangerous, divisive, dishonest politics.” However, countering One Nation’s appeal requires more than rhetorical flourishes—it demands concrete policy responses that address the economic insecurities driving voter anger.
Labor’s best opportunity lies in focusing on tangible cost-of-living measures that directly impact working families, rather than relying on traditional wedge tactics or preference deals that may inadvertently legitimise extremist positions.
Why it Matters
The Secret Harbour by-election represents more than just a local electoral victory—it signals a fundamental realignment of Australian political loyalties that could reshape the nation’s party system for generations to come. As voters demonstrate their willingness to abandon traditional allegiances in favour of anti-establishment alternatives, both major parties must reckon with a electorate increasingly prepared to “burn the whole show down” rather than accept the status quo. The failure of successive governments to address mounting economic pressures and cultural anxieties has created fertile ground for populist movements to flourish, making the next federal election a potential watershed moment that could see Pauline Hanson’s influence extend far beyond the protest vote category into genuine governing power.
