Multiculturalism, trust, and the foundations of cohesion
In recent weeks, Pauline Hanson, leader of One Nation, renewed her call for Australia to become a “monocultural” society operating under a single cultural framework:
“We cannot be a multicultural society; we are a multiracial society, but we must be monocultural. Australians must live under the one cultural umbrella.”
Such statements may appear to reflect familiar rhetoric from the political margins. Yet in Australia—and across many Western democracies—they point to a deeper question: can societies shaped by large-scale migration maintain cohesion, trust, and a shared sense of belonging?
Australia is particularly important in this debate because it represents one of the world’s most successful multicultural democracies. The question it poses is therefore not theoretical, but practical: what actually holds such a society together?
The concern itself is not unfounded. All societies depend on a minimal shared framework of norms, expectations, and obligations that makes collective life possible.
The Australian experience, however, suggests that this framework does not require cultural uniformity. This debate has been especially relevant to Greek Australians, one of the country’s oldest migrant communities, for whom integration has been experienced less as a policy construct and more as a gradual process of belonging.
Today, nearly half of Australians were either born overseas or have at least one overseas-born parent, and more than 300 languages are spoken across the country. Despite this diversity, Australia remains politically stable and performs relatively strongly in comparative measures of institutional trust and governance . The more interesting question is therefore not whether diversity exists, but why it has not undermined cohesion in the way many fear.
What holds a diverse society together?
A common assumption is that trust depends primarily on cultural similarity.
While shared customs can facilitate cooperation locally, they cannot explain how modern societies function at scale. Everyday life in Australia depends on constant interaction between people who differ in language, religion, and background.
What makes this possible is not cultural uniformity, but confidence in institutions.
Citizens do not need shared ancestry or tradition in order to cooperate. They need confidence that rules are applied consistently, that contracts are enforceable, that elections are legitimate, and that public administration is predictable.
Comparative research on advanced democracies consistently suggests that institutional quality is a stronger predictor of social cohesion than cultural similarity alone. Australia is instructive because its cohesion rests less on shared ethnicity than on a civic framework capable of accommodating difference.
What unites Australians is not origin, but trust in a shared civic order.
Political science distinguishes between particularized trust—trust within close social networks—and generalized trust, which extends to strangers. Modern societies depend heavily on the latter. Institutions establish the rules of cooperation, but civic norms and everyday social practices sustain them. Schools, workplaces, sporting clubs, and voluntary associations translate formal citizenship into lived belonging.
This institutional foundation did not emerge automatically; it was historically constructed.
How the Australian civic settlement emerged
For much of the twentieth century, Australia operated under the White Australia Policy, based on the assumption that national unity required cultural homogeneity.
After the Second World War, economic expansion, labor shortages, and international engagement gradually undermined this model. Australia shifted toward a civic conception of belonging grounded in shared institutions rather than shared ethnicity.
What emerged was a civic settlement in which belonging is defined less by ancestry than by participation in democratic institutions and acceptance of common political norms. This logic reflects an older intellectual tradition: the Greek conception of the polis, where citizenship was defined not by origin but by participation in collective civic life.
For Greek Australians, this principle has particular resonance. As one of the country’s oldest migrant communities, they demonstrate that cultural continuity and civic integration are not mutually exclusive. Language, faith, and community institutions have been preserved alongside full participation in Australian public life.
A multicultural society without fragmentation
Australia’s multicultural model does not rest on cultural sameness, but on a shared civic framework.
What unites Australians is adherence to institutions: democratic procedures, equal citizenship, and the rule of law.
International experience shows that diversity alone neither guarantees success nor causes failure. Societies tend to experience strain when rapid demographic change coincides with weak institutions, limited economic opportunity, or declining public trust.
Australia’s relative success lies not in avoiding diversity, but in embedding diversity within stable civic institutions.
The benefits—and conditions—of openness
Migration has strengthened Australia’s economy, expanded international networks, and increased its capacity for innovation. Migrant communities connect Australia to global flows of trade, knowledge, and investment.
Yet the central question is not whether migration is beneficial in principle, but whether it can be sustained within a trusted institutional framework.
For a geographically remote country, openness is a national asset. But its benefits depend on maintaining institutions that allow both newcomers and established communities to flourish.
Where the real pressure lies
At the same time, cohesion is never guaranteed.
Recent polling has shown a significant decline in public support for multiculturalism alongside growing concern about migration levels, housing affordability, economic security, and the performance of government. These findings are important because they suggest that support for multiculturalism is not unconditional. It depends partly on whether citizens believe that growth, migration, housing, and infrastructure are being managed effectively.
Part of Australia’s success has rested on a deeply rooted civic expectation often described as the “fair go”—the belief that people should be judged by their actions rather than their origins, and that everyone deserves a reasonable opportunity to succeed.
Economic pressures—particularly housing affordability, stagnant wages, and widening inequality—have contributed to growing concerns about fairness and social mobility.
People may not be losing confidence in diversity itself so much as losing confidence in the institutions responsible for managing its consequences. Concerns about migration often intensify when citizens believe that governments are failing to provide adequate housing, infrastructure, economic opportunity, or long-term planning.
Multiculturalism should not be viewed as a permanent achievement but as an ongoing institutional accomplishment. It depends upon maintaining the conditions that make diversity workable: economic opportunity, social mobility, effective public services, and confidence that the rules apply fairly to everyone.
Societies do not become unstable simply because they are diverse. They become fragile when citizens begin to doubt that the system treats them fairly or that the promise of a fair go applies equally to everyone.
These dynamics are contested, and countries have responded in different ways depending on institutional capacity and political choices. Spain, for example, has periodically regularized undocumented migrants while maintaining relatively flexible integration pathways, reflecting a pragmatic adjustment to labor-market needs and administrative constraints rather than a single fixed model.
Civic trust is difficult to build, but surprisingly easy to lose.
Conclusion: a different kind of unity
The debate between monoculturalism and multiculturalism is often presented as a binary choice, but this framing obscures the real issue.
Successful multicultural societies do not require cultural uniformity, nor do they ask citizens to abandon inherited identities. Rather, they depend on institutions that enable people from different backgrounds to cooperate as equal citizens within a shared civic framework.
Cohesion does not arise from shared origins, but from shared confidence in the legitimacy of the civic system that governs collective life.
The challenge for modern democracies is therefore not to eliminate cultural difference, but to preserve the institutional trust that allows difference to coexist productively.
National unity is strongest not when citizens share the same background, but when they share confidence in the same civic future.
