In a country where housing costs have become a defining anxiety, Australia's Reserve Bank governor Michele Bullock offered a careful corrective to a familiar political reflex: migration, she argued, is not the engine of inflation it is often made out to be, but rather a quiet sustainer of growth in an economy where productivity has lost its momentum. The exception — and it is a significant one — is housing, where the pace of human arrival has outrun the slower rhythms of construction and planning.

RBA chief: migration drives growth, not inflation—but housing market bears the cost
An 11-year-old boy was shot in the face and neck in Sydney and remains in critical condition; police are investigating possible organized crime links.
Housing is where the pressure becomes acute and visible.

So the RBA governor is saying migration isn't causing inflation. That seems to contradict what a lot of people believe they're seeing in their grocery bills and rent.
Mimi
Right, but Bullock's point is more specific. She's saying that when immigrants arrive and work, they add to supply as well as demand. The economy grows in both directions at once. It's not just more people chasing the same goods.
Luke
But that's a claim about the overall economy. What about specific sectors? She admits housing is different.
Mimi
Exactly. Housing can't build fast enough. So while immigrants might not be driving inflation in, say, food or manufacturing, they absolutely are in housing because supply is stuck.
Mark
So the government's plan to reduce immigration—is that the right response?
Mimi
Bullock doesn't say. She's just describing what the data shows. Tighter immigration might ease housing pressure, but it also means slower economic growth, since the economy isn't generating productivity gains on its own.
Luke
And we should note she's speaking about Australia specifically. She says the economy is weak and efficiency gains are lacking. That's the real problem underneath all this.
Mark
What about the AI stuff she mentioned? That seemed like a separate concern.
Mimi
It's related, actually. Central banks everywhere are hoping AI will solve the productivity problem. But right now it's just adding to inflation without delivering any of those efficiency gains yet.
Luke
And she's careful to say she doesn't know if it's a bubble. She's watching it, worried about it, but not making a prediction.
Mark
So we're in this weird moment where we need growth but we're getting inflation instead.
Mimi
And housing is the place where you can actually see it happening—where the constraints are real and immediate.
The Pulse
- Political pressure to blame immigration for rising costs runs headlong into the RBA's own data, which shows migrants add to supply and demand in roughly equal measure — except in housing, where the math breaks down.
- Australia's housing market is caught between a long era of underbuilding and a sudden surge in population, leaving new arrivals and existing residents competing for a stock of homes that cannot grow fast enough.
- Interest rate rises have hit hardest where fixed-rate mortgages are rare — only 5 percent of borrowers were shielded — meaning most households have already absorbed the full weight of tighter monetary policy.
- The AI investment boom is creating an uncomfortable lag: spending on datacenters and infrastructure is heating the economy now, while any productivity payoff remains speculative and distant, a dynamic Bullock flagged as a potential bubble in the making.
- Within the opposition, a public rift over superannuation-backed home loans exposed the deeper fault lines in Australian politics around housing affordability — with no clear consensus on whether the answer lies in unlocking retirement savings or elsewhere.
In a country where housing costs have become a defining anxiety, Australia's Reserve Bank governor Michele Bullock offered a careful corrective to a familiar political reflex: migration, she argued, is not the engine of inflation it is often made out to be, but rather a quiet sustainer of growth in an economy where productivity has lost its momentum. The exception — and it is a significant one — is housing, where the pace of human arrival has outrun the slower rhythms of construction and planning. Separately, Bullock turned her gaze toward artificial intelligence, raising the possibility that the world may be paying inflationary prices today for productivity gains that may never fully arrive.
Reserve Bank governor Michele Bullock used a Sydney address this week to push back against a prevailing political narrative: immigration, she argued, is not meaningfully driving inflation. When working-age migrants enter the workforce, they add to both labor supply and consumer demand in ways that largely offset each other across the broader economy. The math, she suggested, roughly balances — with one glaring exception.
Housing is where that balance breaks down. New construction is slow, planning approvals slower still, and available land finite. Migrants arrive into a market already strained by years of underbuilding, and the result is visible in prices, in affordability, and in the daily experience of people searching for somewhere to live. Bullock's framing was deliberate: migration is not the broad villain in the inflation story, but the housing market's structural inability to absorb population growth is a genuine and pressing problem.
Her comments arrived as the government moves to tighten immigration intake amid public anxiety about housing costs. Bullock noted that prices are falling, but from a level she described as 'pretty unaffordable' — a modest correction after a very long run-up. With only 5 percent of mortgages at fixed rates, most borrowers have felt the full force of rate rises. Investor activity has also dropped sharply following tax reforms, reducing both rental supply and the incentives for new construction. As values fall and sales slow, the effects ripple outward — less spending on furniture, less consumer confidence among households who feel poorer on paper.
Bullock also raised a separate concern gaining attention among central banks globally: the AI investment surge. Meta's shares leapt 11 percent after unveiling a new AI agent, yet Bullock said there is little evidence these investments are yet making economies more productive. Spending on datacenters and infrastructure is adding to demand — and therefore to inflation — while the efficiency gains remain hypothetical and future-dated. She described it as an awkward sequencing problem, and left open the question of whether the boom represents genuine transformation or a bubble whose unwinding could unsettle financial markets.
On the political front, opposition leader Angus Taylor distanced himself from a proposal by shadow housing minister Andrew Bragg to allow superannuation to be used as collateral for home purchases — a rift that revealed how fractured the debate over housing affordability remains, even within a single party.
Australia's Reserve Bank governor Michele Bullock made a case this week that runs counter to much political rhetoric: migration is not driving inflation, but rather propping up economic growth in a country where productivity gains have stalled. Speaking at a CEDA lunch in Sydney, Bullock argued that the influx of working-age immigrants adds to both demand and supply in roughly equal measure. When people arrive and enter the workforce, they contribute labor and output even as they consume goods and services. The math, she suggested, largely balances out across the economy.
But Bullock was careful to name the exception. Housing is where immigration's pressure becomes acute and visible. The housing market cannot respond quickly enough to population growth. New construction takes time, planning approval takes longer, and the supply of available land is finite. So while immigrants might add to the productive capacity of the economy in most sectors, they arrive into a housing market already constrained by years of underbuilding. That constraint is where the real cost of rapid population growth shows up—in prices, in affordability, in the lived experience of people trying to find a place to live.
The RBA governor's comments came as the government defends its plan to tighten immigration intake, a policy shift that reflects growing public concern about housing costs and the speed of demographic change. Bullock's framing offers a more nuanced picture than simple blame: migration itself is not the culprit in inflation broadly, but the housing market's inability to absorb rapid population growth is a genuine problem that demands attention.
Separately, Bullock raised concerns about artificial intelligence investment that echo worries across the world's central banks. The AI boom is driving stock prices higher—Meta's shares jumped 11 percent on Monday after the company unveiled a new AI agent—but Bullock said there is little evidence yet that these investments are making economies more productive. Instead, the rapid spending on datacenters and AI infrastructure is adding to demand in an economy already running hot, pushing up prices without offsetting supply gains. She described this as an awkward sequencing problem: the productivity benefits of AI, if they come, lie in the future, but the inflationary costs are arriving now. Central banks are watching to see whether the AI investment boom is a genuine transformation or a bubble that could unwind in ways that destabilize financial markets and the broader economy.
On the housing front specifically, Bullock noted that prices are falling but from a level that was "pretty unaffordable." The current downturn sits in the lower range of past corrections, she said, a modest decline after a very long run-up. Interest rate rises have been the primary driver, with only 5 percent of mortgages locked in at fixed rates, meaning most borrowers have felt the full impact of higher rates. The government's tax reforms have also weighed on the market, particularly investor housing approvals, which have dropped sharply. Fewer investors buying rental properties changes the dynamics of the market and the incentives for new construction. As house prices fall and sales slow, the economic ripple effects spread: people buy less furniture and fittings, and households that feel poorer because their home is worth less tend to spend less overall.
Meanwhile, the political debate over housing and immigration continues to shift. The opposition leader Angus Taylor distanced himself from a proposal by shadow housing minister Andrew Bragg to allow Australians to use superannuation as collateral for home purchases. Taylor said the idea is "not our policy," though Bragg had framed it as part of a broader push to create a nation of homeowners rather than renters. The tension within the opposition reflects deeper disagreement about how to address housing affordability—whether through loosening restrictions on how people access their retirement savings, or through other means.
