The ongoing debate over immigration in Australia extends beyond numbers, reflecting deeper economic and cultural divisions about national identity and shared values. While discussions often focus on the volume of migrants allowed into the country, experts argue that the issue is part of a broader challenge facing liberal democracies worldwide.

Daron Acemoglu, a 2024 Nobel laureate in economics, frames this as a post-industrial crisis in liberal democracy, where the system no longer delivers broadly shared economic prosperity or empowers the populace as intended. Immigration sits at the heart of this debate because it raises fundamental questions about belonging and cultural cohesion, which, if left unaddressed, can fuel support for illiberal populist movements.

In Australia, public attitude data tracked over more than a decade shows general support for immigration has remained stable, even amid intensified political controversy. However, the rise of the One Nation party has reshaped the conversation. Once a minority viewpoint inside the major parties, opposition to immigration now has a prominent political platform. One Nation’s straightforward demand to reduce immigration resonates with voters concerned about job security, housing affordability, community safety, and access to public services, simplifying complex social and economic issues into a single narrative.

At the same time, major political parties have expanded short-term visa programs to address immediate workforce needs, sometimes at the expense of long-term skills development and planning. Critics argue that these issues are often dismissed by political elites as divisive or racially motivated, which only exacerbates public frustration. Acemoglu describes this dynamic as a "toxic sludge" undermining liberal democracy—a combination of economic elites enforcing business priorities and cultural elites marginalizing legitimate concerns.

Economic instability, rising living costs, and rapid technological change have contributed to political backlash, making immigration a lightning rod for broader anxieties. Recent polling suggests Australia may be at a turning point, with a growing majority supporting a reduction in immigration levels or a slowed pace of arrivals. This shift was underlined by Immigration Minister Tony Burke’s recent admission that reducing immigration numbers is now official government policy. He detailed specific policy changes affecting student visas, working holiday ballots, and family reunions, all of which enjoy strong public support according to recent surveys.

Meanwhile, the opposition Coalition faces challenges positioning itself between Labor’s incremental adjustments and One Nation’s hardline stance. Attempting to frame immigration as a policy trade-off with housing supply has met with skepticism, as most voters convinced immigration is too high say more housing alone would not alter their views.

Voter preferences highlight a fragmented landscape: Labor supporters generally favor moderated immigration, Coalition voters split between slowing and tightening controls, One Nation advocates for sharp reductions, and Greens tend to emphasize the benefits of immigration.

The political tug-of-war over immigration reflects a deeper question about Australia’s future. Many citizens seem to seek a balanced approach that prioritizes control over the pace and scale of immigration, rather than outright opposition. Acemoglu suggests “working-class liberalism” as a potential path forward, advocating for empowering local communities, fostering open dialogue, and maintaining a continuous evaluation of policies to bridge divides and sustain democratic legitimacy.
