In a market full of opinions, forecasts, and noise, two numbers cut through everything. They reveal exactly what’s happening beneath the surface… and where the property market is heading next.
Let’s get straight to them.
Key Property Investment #1: Rental growth rate – 5.5%
Rents are rising at 5.5% right now.
At first glance, that might not feel dramatic; after all, inflation sits at 3.8%, so rents are only 1.7% above inflation.
But here’s why this number should make every property owner sit up:
- At this time last year, rental growth was just 3.2%
- Inflation then was 2.4%
- Rental growth was only 0.8% above inflation.
That’s not “normal market movement.” That’s a structural shift.
Key Property Investment #2: National vacancy rate – 1.1%
A balanced rental market sits around 2.5% vacancy; that would mean enough supply to meet demand without pressure building.
Today we are at 1.1%.
That’s not just tight. That’s critical. And the most important detail?
This time last year, vacancy was 1.3%. Meaning it’s getting worse, not better.
Where the two numbers converge
These two forces – surging rental growth and shrinking vacancy – aren’t unrelated.
They’re two sides of the same coin.
Vacancies drop → supply tightens → rents rise faster → rental growth outruns inflation → repeat.
This is Australia’s housing crisis unfolding in real time.
When population growth runs ahead of housing construction, renters shoulder the immediate cost. Unless supply meaningfully catches up, this dynamic won’t reverse anytime soon.
What it means for property investors
This is why talk of sweeping changes to capital gains tax or negative gearing never gets traction. With rental supply already at breaking point, policymakers know further disincentivising investors would be politically and economically risky.
It’s also why I’m not overly concerned about the possibility of one or two more rate rises. In a market this tight, demand for rentals remains strong – and rents continue rising – cushioning investors from any change in rates.
These two numbers – 5.5% rental growth and 1.1% vacancy – matter more than anything else in the news cycles right now.
Everything else is just noise.
