Australia’s rental crisis: What low vacancy rates mean for property investors

Australia’s rental market has been tight for years, but the headlines rarely explain what that actually means for someone deciding where, and what, to buy. “Vacancy rates are at record lows” gets reported as a single, simple signal, when in practice it’s one input into a much bigger picture.

This article looks at what today’s vacancy data actually shows, why a low number isn’t automatically a green light, and how we use vacancy alongside supply and population data when assessing a market.

What is Australia’s current rental vacancy rate?

The national rental vacancy rate sat at 1.3% in July 2026, according to SQM Research, roughly level with a year earlier after briefly dipping to 1.0% in March. Brisbane, Perth, Adelaide, Darwin and Hobart are all currently recording vacancy rates below 1%. Sydney and Melbourne have eased slightly over the same period, but remain well under what’s considered a balanced market.

National asking rents were still running around 8% higher year-on-year as of mid-2026, even as month-to-month growth has softened in some cities.

Does the rental crisis make property a good investment?

Not automatically, and that’s an important distinction. A tight rental market makes it easier to find a tenant and support a rental return, which matters because most investors need to hold a property, and keep it rented, long enough for capital growth to do its work. But low vacancy on its own doesn’t tell you whether a specific property, in a specific suburb, is a sound long-term buy.

“Most Australians are buying investment properties to achieve long-term capital growth. But in order to be able to hold the property over the long term, they still need to be able to rent it out and achieve a decent rental return. Whilst the property might rent easily, if it is a property type aimed solely at investors or there are future oversupply issues, then they may still struggle with long-term capital growth i.e. Docklands in Melbourne” – David Hancock, Director at Binnari Property

Treating vacancy as a single green light, rather than one input among several, is where investors tend to go wrong.

What is considered a healthy vacancy rate?

A healthy, balanced vacancy rate is generally considered to sit somewhere around 2.5% to 3%. At 1.3% nationally, Australia remains well under that.

“Generally, a healthy, attractive vacancy rate sits at around three per cent.” – David Hancock, Director at Binnari Property

Is a low vacancy rate good for the property markets and what’s happened since the Federal Budget in May?

It depends which side of the transaction you’re on.

“It’s a positive sign if you’re investing. It’s not a positive sign if you’re a tenant, because you’re going to be competing with a lot more people. The more competition typically means the more landlords can ask, and you’re going to see rents rising. The removal of Negative Gearing and changes to Capital Gains Tax (CGT) for established properties in the May Federal Budget has had a major impact on investors sentiment in purchasing established property. The sharp fall in investor activity since May is beginning to impact the overall rental supply, which will only lead to further rental increases in the coming years. – David Hancock, Director at Binnari Property

For an investor, tighter competition among tenants generally supports rental income, which is exactly why vacancy is one of the metrics we track closely. But it’s a signal about rental demand, not a verdict on the property itself.

What vacancy rate can’t tell you on its own

Vacancy is a single snapshot: it tells you how many properties are currently listed for rent, relative to the total pool. It doesn’t tell you how large that overall rental pool is, whether it’s growing or shrinking, or what’s coming onto the market next.

That overall pool matters just as much as the vacancy percentage. In much of the country, the number of properties available to rent has been shrinking, partly because properties are moving out of the rental pool and into owner-occupied purchases, and partly because fewer investors have been purchasing established homes since May’s Federal Budget changes to negative gearing. At the same time, net overseas migration, while easing from its post-pandemic peak, remains well above the pre-COVID decade average, adding steady demand for rental stock.

“This is just a pure supply and demand equation.” – David Hancock, Director at Binnari Property

Fewer available rentals and steady population growth point toward continued upward pressure on rents in most markets.

Our fundamentals framework

Vacancy rate is one signal we track, but it sits inside a wider fundamentals framework rather than standing alone. Alongside vacancy, we look at the overall size of the rental pool, population growth and migration patterns, and how much future supply is likely to come onto the market in a given area. A property can look attractive on vacancy alone and still be a weak long-term buy if the property type does not appeal to owner occupiers or the particular property market is at risk of being over supplied in the future.

How can you tell whether low vacancy will last?

The clearest sign that tight vacancy is structural, rather than a temporary blip, is a lack of new supply coming through behind it.

“For many property markets it’s not temporary, because the only way we can fight our way out of this is to create more supply, and to incentivise investors to get back into the market.” – David Hancock, Director at Binnari Property

What causes rental undersupply?

Australia is running well behind its own housing targets. Under the National Housing Accord, all levels of government committed to 1.2 million new homes by mid-2029; by early 2026, the country was already more than 100,000 homes behind the pace needed to hit that goal, with completions consistently falling short of quarterly targets.

The Federal Budget’s tax changes were partly designed to redirect investment toward new housing, by preserving negative gearing and CGT concessions for new builds while restricting them for established properties bought after budget night. In principle, that should encourage more new supply over time. In practice, not every investor is comfortable with, or experienced in, buying off the plan or newly built property, so it’s unlikely the tax incentive alone will be enough to shift enough investors into the new-build market fast enough to close the gap.

“The federal budget did leave tax incentives for new property, but we haven’t seen any significant uptick in new property demand yet as demand remains stable. So what we’re seeing is a situation where the rental pool is shrinking, and not enough new supply is being brought on. That would tend to suggest this is more a structural, long-term issue, and it’s going to take a lot more initiatives and a much longer timeframe to fix.” – David Hancock, Director at Binnari Property

Combined with investor loan commitments for established property down sharply since the Budget, that leaves a rental pool that’s likely to keep tightening before it eases. “Should I buy a new build to keep negative gearing benefits?”.

The risk of chasing headline rental yields

A high advertised rental yield is one of the easiest numbers to be drawn to, and one of the easiest to get wrong. The clearest cautionary example is regional mining towns during the mining boom, when investors chased strong short-term yields in single-industry areas.

“When the mining sector went through its normal cycles and the demand for those properties wasn’t there, the people that bought these properties either had to take substantially lower rent, or they couldn’t rent them at all.” – David Hancock, Director at Binnari Property

Regional and single-industry markets can also come with another risk: room to keep building. Even where current yields look attractive, an area with few constraints on new supply can see that supply arrive quickly, capping both rental growth and capital growth at the same time. The result in many of these markets has been investors who secured a strong yield at outset, have missed out on the capital growth they might have achieved in a major city or key regional centre.

The lesson isn’t to ignore yield, but not to chase it in isolation. It’s worth checking that a market also has a strong, diverse local economy and employment base, and that you’re buying an owner-occupier-type property that’s genuinely in demand and short supply, rather than one that happens to carry an attractive headline yield in the short term.

How important are population growth and future housing supply?

The two move together. Migration adds to housing demand, but new arrivals don’t spread evenly across the country. They tend to concentrate in particular cities and pockets within them, which puts uneven pressure on local rental markets rather than a uniform national squeeze. Where housing supply in those areas isn’t keeping pace, the existing tightness gets worse, not better.

How we use vacancy data in our research process

Vacancy rates are one factor we look at when researching a market, but never in isolation. We’re interested in both current and future rental vacancy: is a property in an area likely to be flooded with thousands more similar dwellings, or is it one of a small number available to investors in a small, predominantly owner-occupier-purchased development, with limited room for further supply?

That question shapes which areas we avoid as much as which ones we recommend.

“We really want to avoid areas where there is a lot of supply coming, where the ability to bring on lots of similar types of properties feels almost infinite.” – David Hancock, Director at Binnari Property

The western suburbs of Melbourne are one example: flat, outer-suburban land where new house-and-land products can keep being released at scale, which makes it hard to generate rental price pressure or capital growth. Apartment precincts like Docklands in Melbourne or Macquarie Park in Sydney illustrate a similar problem. Both areas have high volumes of investor-owned stock with limited natural owner-occupier demand, where it’s difficult to differentiate one unit from the next new building coming out of the ground. This again makes strong capital growth harder to achieve.

It’s typically safer to locate house and townhouse product in infill locations across major cities and key regional towns, where supply is genuinely limited and the predominant purchaser is a local owner-occupier rather than another investor.

Will Australian rents continue rising?

On current data, most of the underlying conditions point that way. Vacancy remains well below balanced levels nationally, the rental pool is under pressure from both reduced investor demand post May budget and continued population growth, and new supply is running well behind the pace needed to close the gap. None of that guarantees uniform rent growth in every market, but it does mean the structural pressure behind Australia’s rental crisis has gone away.

Tight vacancy currently looks structural rather than temporary, given how far new supply is running behind housing targets
Chasing a high headline yield without checking the underlying fundamentals, particularly future supply, can leave investors with weaker capital growth than expected
Population growth and future supply, not just today’s vacancy figure, determine whether current conditions are likely to persist
