Australia Is Ageing Fast, and Its Own Report Says Migrants Fill the Gap
News · 2026-09-22 · 4 min read
Let us cut through the noise. Headlines about Australia's new Intergenerational Report (IGR) have mostly been about deficit figures and bad news for the budget. But for anybody following migration, the most important line sits a few paragraphs into the document: the country has admitted, without much fanfare, that it cannot sustain itself unless immigration continues at a steady, planned level.
The one assumption holding up 40 years of forecasts
The report assumes net overseas migration (NOM) of 235,000 people per year, every single year, for the next four decades. Treat that as the foundation, not a side note. Remove it and the 40-year economic forecast loses the wall it stands on.
Why does Australia need it so badly? Because the official long-term modelling now says that by the 2060s, deaths in Australia will outnumber births each year. This is the government's own projection, not some outside commentator guessing.
A birth rate that keeps sliding
For over half a century, fertility in Australia has stayed below replacement level. The IGR has cut its assumption yet again, from 1.62 children per woman in 2023 down to only 1.34 by 2065-66.
Japan, Germany, Italy and South Korea are examples of where that kind of trend ends up: economies already contracting as their age pyramids grow top-heavy. Australia is not on that path, and the single reason is migration.
Age is the real advantage newcomers bring
Here is a detail many readers will skip. Incoming migrants have a median age of 26. The resident population's median age is 38. In practice, migration is the strongest tool Australia has for slowing down how fast its whole workforce gets older; it is not simply about adding numbers.
The report expects the working-age population (15–64) to grow, but that growth only comes with migration. Australia remains one of a small group of developed nations still planning for a bigger labour force through the middle of the century, and migrants are doing almost all of that work.
Caring jobs: where demand is building
The IGR names a transition to a "care economy" in plain words. Health, disability support (NDIS) and aged care are all growing, with the population over 65 nearly doubling and the over-85 group nearly tripling. Historically, these sectors have leaned heavily on migrant labour, from direct care workers right across the broader health workforce. If that demand turns out as projected, care-related occupations deserve close attention from anyone weighing skilled or semi-skilled options.
Growth targets that depend on intake
The brighter projections in the report include an economy that doubles by 2065-66, real incomes rising 55% higher, and unemployment close to 4.25%. All of them rest on the same migration figure. Push the intake materially below 235,000 a year and population ageing accelerates beyond what those projections assume. Health and aged care, already flagged as major drivers of future government spending, would then face heavier pressure earlier, with fewer working-age taxpayers to fund them.
The election factor
This is where it gets tricky. The IGR's baseline is 235,000 NOM per year. Meanwhile, the Coalition and One Nation have both campaigned on reducing the migration intake well below that number. So the modelling the government stands behind is on a collision course with the policies being floated from the opposition benches.
Whether you are a migration adviser, an employer relying on skilled visa pathways, or someone hoping to migrate, watch this closely over the next few election cycles. The 39.3 million population projection is not the real story. The real question is whether the intake settings behind it survive domestic politics.
Straight talk before you plan
In plain terms, Australia's official 40-year economic outlook is a migration story with an economics chapter attached. The report does not sit on the fence: it states that migration gives Australia "demographic resilience" that its ageing peers do not have. Nobody is asking whether migration will stay central; the open question is whether political support for the intake levels in the modelling will last over the next few elections.
One last word of caution. Strong demand for workers also attracts fraudsters. A genuine employer will never ask you to pay for a job offer, so verify every opportunity and rely on official sources for visa information before you spend a kobo.
