Australia’s debate over immigration is shifting in an unusual direction: away from the headline number and toward how long people stay. A new paper argues that the country’s real problem is not just net overseas migration, but the growing scale of temporariness. Temporary migrants now make up more than 6% of the population, up from 2. 7% in 2010, and that change has become central to pressure on housing, infrastructure and public services.
Why the immigration debate matters now
The argument put forward by Alan Gamlen, director of the Australian National University’s migration hub, and emeritus professor Peter McDonald is that the usual political fixation on net overseas migration has obscured a more practical question: how many temporary residents can Australia sustainably absorb? Their paper says Australia should set immigration targets that aim for a “stable temporary population, ” rather than treating temporary arrivals as an open-ended category.
That framing matters because it links population policy directly to capacity. If temporary migrants continue to grow as a share of the population, the pressure is not abstract. It is felt in housing supply, the availability of services and the broader question of whether infrastructure keeps pace. The paper’s central claim is that Australia has not managed the stock of temporary migrants well enough over recent decades, and that this failure has fed concerns around social cohesion and “mass migration. ”
The scale of temporariness behind the headline
The key statistic is stark: temporary migrants rose from 2. 7% of the total population in 2010 to more than 6% today. That more than doubling is why the authors argue that immigration should be governed with a clearer target for temporary residents. In their view, the issue is not simply how many people enter each year, but what proportion remains in temporary status for long periods and how that shapes the country’s social and economic capacity.
Gamlen said Australia needs “a better way to govern ‘temporariness’. ” He added that the aim should be “a stable temporary population, ” and that the question is not which net overseas migration figure sounds politically attractive, but what scale of temporariness Australia is willing and able to sustain. That is a significant policy shift: it moves the debate from annual totals to structural management.
The authors also propose a more active link between temporary and permanent migration. In their paper, they say Australia should set a number for temporary migrants and manage long-term population by moving more or fewer temporary visa holders into the permanent program. In practical terms, that would connect immigration settings to Australia’s capacity to support settlement through infrastructure development, rather than allowing a large “guest worker” population to accumulate with unintended consequences.
What the Canada example suggests
The report draws a comparison with Canada, which in late 2024 began a migration reset that included a cap on temporary arrivals. The goal there was to lower the share of temporary migrants from 7. 6% to 5% of the population. Experts say Canada’s population is now shrinking for the first time since the 1940s, and there is evidence the policy has reduced pressure on housing costs.
Gamlen said Canada was right to focus on the stock of temporary migrants rather than net migration, because that is the target that relates directly to public concerns and the levers governments can actually control. But he also argued that Canada’s 5% target was arbitrary and that the cuts were made too quickly, causing economic harm. For Australia, the lesson is more cautious: immigration can be reshaped without repeating a sharp policy shock.
Expert view and the policy stakes ahead
The Australian National University paper places immigration inside a broader governance problem: how to balance labour demand, housing capacity and settlement pathways without letting temporary status become the default state for too many people. That is where the report’s language is most revealing. It does not call for simple reduction; it calls for better management.
As Gamlen and McDonald frame it, the real test is whether Australia can align immigration with the country’s capacity to support permanent settlement. If that alignment fails, the result is not only demographic pressure but also deeper political conflict over what kind of migration system the country wants.
The next question is whether policymakers will continue debating net overseas migration figures, or finally confront the harder issue at the center of immigration: how many temporary residents Australia can actually sustain.
