Australia has become very good at growing the size of its economy. We add people, build homes and direct significant household wealth into property. What we have been less successful at is lifting output per person.
Population growth can lift headline GDP, but productivity drives GDP per person, real wages and living standards. Without matching migration and property growth with investment in technology, infrastructure, skills and businesses, the economy can grow without Australians becoming better off.
This is not an argument against immigration or property. Both matter. It is an argument for being clearer about the growth Australia wants and where our capital goes.
Property has dominated the conversation
For decades, rising values, accessible debt and favourable tax settings have made residential property a preferred wealth-building vehicle, particularly established housing.
The 2026 Federal Budget begins to shift that balance. From 1 July 2027, negative gearing will generally be limited to new builds purchased after Budget night, with existing holdings grandfathered. The aim is to direct investment towards new supply rather than existing homes.
But the broader issue remains: capital used to bid up existing assets can create wealth without adding productive capacity. It does not necessarily build businesses, improve technology, expand exports or help workers produce more.
Property will remain important. The question is whether it has become too dominant, and productive business investment comparatively less attractive.
Immigration grows the economy, but not automatically living standards
Immigration delivers real benefits. It fills skill gaps, supports labour-short industries and connects Australia to new ideas and markets.
However, more workers do not automatically mean a more productive economy. In the year to March 2026, Australia’s population grew by around 392,700 people, including 292,100 through net overseas migration. Headline GDP grew, yet GDP per person fell 0.1% in the March quarter and labour productivity fell 0.6%.
Migrants did not cause weak productivity. The point is that population growth can make the headline economy look healthier than the experience of the average person. If output rises mainly because there are more producers and consumers, living standards can still stagnate.
The risk of capital shallowing
This leads to capital shallowing.
Workers are more productive when they have better tools, technology, transport, energy, housing and infrastructure. If the workforce grows faster than investment in these assets, productive capital per worker falls.
Adding workers may lift total output, but congested roads, scarce housing, delayed automation and stretched services limit what each worker can produce.
Migration policy therefore cannot sit apart from housing, infrastructure, education and business investment. Australia must have the capacity to absorb population growth productively.
Migration should support reform, not replace it
A larger labour pool may also reduce pressure on some businesses to improve systems, train staff or automate. If capacity constraints can be solved by hiring more workers, the incentive to redesign the business may weaken.
This is not true of every employer or a reason to blame migrants. It shows why migration should target genuine shortages, support knowledge transfer and complement investment—not simply expand labour supply.
Temporary residents must also be included honestly in planning. Many students and workers stay for years and need housing, transport, healthcare and services, regardless of how they are classified.
A better growth model
Australia does not need to choose between migration and productivity, or housing and business investment. It needs them to work together.
That means matching migration with housing and infrastructure capacity, targeting genuine skill shortages, and directing more capital into new housing, technology, energy, equipment, research and growing businesses.
Australia’s stagnant productivity matters more than whether headline GDP is positive in any single quarter. Productivity is what sustainably lifts wages and living standards without relying on debt, asset inflation or an ever-growing population.
Immigration can make Australia larger and more capable. Property can provide homes and wealth. Neither should substitute for productivity.
The real test is not how many people we add or how much house prices rise. It is whether Australians have the capital, infrastructure and opportunity to produce more, and enjoy a better standard of living.
