Secret Harbour should wake Australia’s major parties from complacency

A by-election in Western Australia has produced a result that will unsettle more than political forecasters: One Nation stormed a seat long considered a safe Labor hold. The shock victory in Secret Harbour is not just a local upset — it is a symptom. The party’s surge, reflected in a return to the top of Newspoll and marked by loud claims that it can ‘smash’ Labor, exposes a fragility in the major parties’ connection with parts of the electorate. What happened in Secret Harbour matters because of where it happened. Commentators have described the electorate as outer-urban, mortgage-belt country — young families, tradies and a largely Anglo profile. These are voters living with the day-to-day pressures of housing, household budgets and job security. When a fringe or insurgent party makes headway in that terrain, it indicates those pressures are not being heard or addressed by the mainstream. The television spat this week — with a senior Coalition figure declaring ‘there is no safe Labor seat anymore’ in the wake of the result — captures the raw political consequence. Politics is a contest of ideas, but this contest is increasingly being shaped by voters’ lived experience: if people feel their concerns are dismissed, they will vote for voice and disruption rather than the gentle management of the status quo. There is a broader structural backdrop that must give pause. Australia’s demographic profile is shifting: birth rates are below replacement in important areas while an older population is growing. The critic of immigration and the populist critique of established economic institutions that parties such as One Nation deliver risk running headlong into that reality. The combination of an anti-immigration stance with radical ideas on pensions and superannuation — an approach analysts have called a potentially toxic mix — raises uncomfortable questions about long-term national capacity to sustain a workforce, finance ageing, and maintain economic growth. For Labor, the immediate lesson is not just tactical. Losing a seat like Secret Harbour is a warning about complacency. Being in government does not insulate a party from erosion at the edges if voters feel their daily struggles are ignored or their cultural anxieties unacknowledged. For the Coalition, and indeed for all parties, the result should be a reminder that simple triumphalism — or gleeful predictions of opponents’ demise — are poor substitutes for listening and policy delivery. What should change? The response must be practical rather than rhetorical. Parties need policies that speak directly to house-price pressure, cost-of-living concerns and local infrastructure in outer suburbs. They should offer credible plans for retirement security that acknowledge demographic realities, not opportunistic sloganeering. And they must re-engage with communities that feel left behind by the metropolitan-centred debates of recent years. A by-election does not always presage long-term realignment. But Secret Harbour’s profile is precisely the point: if One Nation can convert discontent in the mortgage belt and outer suburbs into seats, the national political map will shift. That ought to concentrate minds across the political spectrum — not only on winning the next campaign, but on policy that actually improves people’s lives. If the major parties respond with introspection and practical policy rather than outrage and invective, Australia is better placed to meet the demographic and social challenges ahead. If they do not, expect more uncomfortable surprises from electorates that are no longer content to be taken for granted.
