House prices are falling. Your rent is not, and 1,825,403 people are why.

House prices are falling. Your rent is not, and 1,825,403 people are why.

Key takeaways

  • Australian house prices fell for a sixth straight month: down 1.1 per cent in September, 5.2 per cent from the March peak, with forecasts of a 10 to 15 per cent total fall.
  • The national rental vacancy rate is 2.0 per cent against a pre-COVID decade average of 3.3 per cent. Prices are falling while the rental market stays tighter than it was for the decade before the pandemic.
  • A price fall is not a supply increase, and with sales volumes down 19.1 per cent it reduces the dwellings that would have eased the queue in future years.
  • At 31 August 2026 there were 2,878,973 people here on temporary visas, 1,825,403 excluding New Zealand citizens, visitors and crew, against a net flow of 292,100. The standing population is six times the number quoted.
  • The ABC's report on falling prices does not mention migration or population once, which is how the national housing conversation is conducted.
  • One Nation's 750,000 reduction with negative net overseas migration is the only proposal that lowers the number of people bidding, which is why it is the one to back.

The good news is not for you

On 1 October the ABC reported Australian house prices had fallen for a sixth straight month: down 1.1 per cent in September and 5.2 per cent from the March peak, with 97 per cent of capital-city suburbs declining over three months. Cotality's research director Tim Lawless put the likely total at "a 10 per cent to 15 per cent drop". AMP's chief economist Shane Oliver said a 20 per cent fall was possible if conditions deteriorated.

If you own a house, that is a headline about your net worth. If you rent, it is a headline about someone else's.

Here is the number in that same report that actually describes your life. The national rental vacancy rate is 2.0 per cent. The pre-COVID decade average was 3.3 per cent. Prices are falling and the rental market is still tighter than it was for the ten years before the pandemic.

Falling prices do not produce a vacant rental. They produce a nervous investor, and a nervous investor builds less.


Vacancy is the number, and it has barely moved

Two per cent sounds close to three point three until you stand in the queue.

A vacancy rate is the share of rental stock available right now. At 3.3 per cent a renter has options and a landlord has to compete. At 2.0 per cent the landlord picks from a line down the footpath and raises the rent because eight other people will pay it. The gap between those two numbers is the entire difference between choosing where you live and being chosen.

And the demand side of that ratio is the thing nobody will name. 1,825,403 people on temporary visas, against net overseas migration of 292,100 for the year ending March 2026. The standing population is six times the flow, and the flow is the only one that appears in a ministerial target.

The ABC's report does not mention migration or population once. That is not a criticism of the reporting, which was about prices. It is an observation about the national conversation: we discuss Australian housing almost entirely in terms of interest rates, investors and approvals, and almost never in terms of how many people are bidding.


What a falling market does not fix

It is worth being precise, because the easing will be used as an argument that the problem is solving itself.

A price fall is not a supply increase. The same dwellings exist. One of them just costs less to buy, which helps a buyer with a deposit and does nothing for somebody who cannot assemble one.

A price fall reduces future supply. Developers build when the finished product is worth more than the cost of building it. Falling prices and a 19.1 per cent drop in sales volumes make projects fail their feasibility tests. The dwellings that would have eased the queue in 2029 are the ones not starting now.

The population does not fall with the prices. The 1,825,403 is unaffected by what a house sells for in Brisbane. Those people need somewhere to live in exactly the same numbers next month.

So the easing you are being shown is an easing in asset values, not in the queue. They are different markets, and only one of them is where a renter lives.


The costs that do not show up in a price index

Housing is the sharpest edge of mass immigration, not the only one.

The first job. 542,204 people here hold skilled or graduate visas with full, uncapped work rights, and they are in the queue ahead of every Australian school leaver.

Wages. Growth by headcount is not growth in prosperity. Output per person pays wages, and adding people faster than productive capacity raises the headline while the people inside it go backwards.

Services. Hospitals, schools and transport are funded per head and delivered per year. A population outrunning delivery means longer waits, and no amount of goodwill closes that gap.

Energy and construction costs. AI data centres are the fastest-growing new electricity load in the country, on a grid that already prices households out, in a nation that exports the energy. Power is an input to every dwelling built. Cheap domestic energy is what would make building affordable and Australian-owned compute viable at the same time.


One Nation is the only party proposing to reduce the number of bidders

Every other party is managing the flow.

Labor is targeting 245,000 this financial year and 225,000 by 2027-28. Those are annual net flows. Meet them exactly and 1,825,403 people are still here, still in the rental market, still ahead of your kids in the job queue.

One Nation's plan reduces the standing population: 750,000 off the temporary migrant population across three years, net overseas migration negative while that happens, then a reviewable cap of 130,000 a year with student visas held to 100,000.

That is the only mechanism on offer that raises the vacancy rate by lowering the number of people competing for a fixed number of homes. It is published as a population, so it can be checked against the Home Affairs workbook every quarter, which a flow target never can be against what a renter experiences.

That is the case for One Nation leading the next government, with the Liberals and the Nationals supporting it. The Liberals under Angus Taylor have moved genuinely on the intake. The Nationals are right that domestic energy costs sit underneath construction costs and the power bill. Neither has put a binding, numbered, reviewable cut to the standing population on paper. One Nation has.


Every year of delay raises the number that has to come down

Prices will stop falling. The 1,825,403 will not fall with them, and another cohort will arrive on permanent pathways while the dwellings that would have housed them fail their feasibility tests.

House prices are falling. Your rent is not. One party has published a plan to change the number that decides which of those two you feel.
