Australia’s long-running debate over immigration, multiculturalism and national identity has intensified following new polling that suggests many Australians continue to support a multicultural society while becoming increasingly concerned about how immigration and integration are being managed.

The discussion was reignited by columnist Louise Roberts, who argued that the central issue facing Australia is no longer whether multiculturalism itself should exist, but whether governments have maintained a sufficiently strong sense of shared national identity as migration has expanded.

Drawing on News24 Pulse polling, Roberts contends that public concern is directed less at migrants themselves than at broader questions surrounding social cohesion, integration, housing pressures and the preservation of Australia’s civic values.

Her commentary reflects one side of an increasingly prominent national conversation that has become a significant issue in Australian politics.

Support for multiculturalism—but growing doubts

According to the polling cited by Roberts, Australians continue to express broad support for multiculturalism as a national principle.

However, she argues that confidence in the way successive governments have managed migration and integration has weakened.

Rather than portraying voters as broadly hostile to immigration, Roberts suggests many are questioning whether Australia’s existing policies are successfully balancing high migration levels with adequate housing, infrastructure and community integration.

She argues that concerns about national identity have become intertwined with wider economic pressures, including rising living costs, housing shortages and slower improvements in household living standards.

The Prime Minister’s remarks

Roberts was particularly critical of comments made earlier this year by Prime Minister Anthony Albanese during a multicultural event.

In that speech, the Prime Minister warned against voices seeking to return Australia to an earlier era and urged Australians to continue embracing diversity as one of the nation’s strengths.

According to Roberts, that framing risks portraying critics of current migration settings as opponents of multiculturalism itself rather than engaging with their concerns about integration and national cohesion.

She argues that many Australians are seeking a discussion about policy rather than questioning the contribution migrants have made to the country.

Australia’s migration history

Immigration has played a defining role in Australia’s modern development.

Following the Second World War, millions of migrants from Europe helped address labour shortages while contributing to rapid economic growth.

Later decades saw increasing migration from Asia, particularly after the dismantling of the White Australia Policy during the 1970s.

Migrants from Vietnam, China and many other countries established businesses, strengthened local communities and contributed significantly to Australia’s economic and cultural development.

Australia’s multicultural model has often been regarded internationally as one of the country’s major public policy successes, combining high immigration with relatively strong social stability compared with many other advanced economies.

The question of integration

Roberts argues that previous generations of migrants generally entered Australia with an expectation of gradually integrating into the country’s institutions, laws and civic culture while preserving elements of their own heritage.

She contends that successful multiculturalism depends upon newcomers sharing a common commitment to Australia’s democratic institutions, legal framework and civic values.

Her article argues that recent policy settings have placed less emphasis on integration, contributing to public concern about national identity.

These views remain the subject of considerable public and political debate, with many researchers noting that integration is a complex, multi-generational process shaped by education, employment, language acquisition and community participation.

Economic pressures shape the conversation

The discussion surrounding immigration has increasingly become linked with broader economic concerns.

Australia has experienced sustained population growth alongside persistent shortages in housing supply, rising rents and elevated property prices.

Many economists acknowledge that rapid population growth can increase demand for housing and infrastructure if construction and public investment fail to keep pace.

At the same time, migration also contributes to labour supply, economic growth and an ageing workforce, making the policy debate considerably more complex than simply determining annual migration numbers.

Roberts argues that population growth should be aligned more closely with Australia’s capacity to provide housing, transport and essential services while maintaining social cohesion.

Security and social cohesion

The article also references concerns surrounding national security and social harmony.

Roberts points to incidents including debates surrounding Australians who travelled overseas to join Islamic State, as well as tensions arising from protests connected to overseas conflicts.

She argues that governments should adopt a firmer approach toward individuals who reject Australia’s democratic institutions or promote extremist ideologies.

Questions about balancing national security, civil liberties and successful integration have become recurring themes in Australian public policy over the past decade.

The political divide

Immigration policy has become one of Australia’s most contested political issues.

While the major parties broadly support a multicultural Australia, they frequently differ over migration levels, border management and the pace of population growth.

Parties such as One Nation have argued for substantially lower migration and stronger emphasis on cultural assimilation, while others maintain multiculturalism remains one of Australia’s defining national strengths.

Roberts notes that criticism of current migration policy is often met with accusations of xenophobia or racism, arguing that such responses risk discouraging legitimate policy debate.

Others contend that public discussion should distinguish clearly between concerns about immigration policy and attitudes toward migrants themselves, recognising that robust debate can occur without undermining Australia’s multicultural foundations.

An evolving national conversation

Australia’s immigration program continues to be regarded as central to the nation’s long-term economic development, labour market and demographic future.

At the same time, questions surrounding housing affordability, infrastructure capacity, integration and national identity are becoming increasingly prominent in public debate.

The differing perspectives reflect a broader challenge confronting many advanced democracies: how to maintain the economic and cultural benefits of immigration while ensuring strong social cohesion and public confidence in government policy.

For Roberts, the central issue is whether Australia can preserve a confident national identity alongside continued multiculturalism.

Regardless of where Australians stand on that question, the debate demonstrates that immigration policy is no longer being discussed solely through the lens of border numbers. Increasingly, it is becoming a wider conversation about national identity, civic expectations and the future direction of Australian society.
