A published vacancy rate is a different fraction. A 2019 Reserve Bank of Australia research paper describes it as the number of properties listed as available for rent, divided by the total number of rental properties.

You set the first number in your own budget. The second describes an area, and AHURI found different ways of counting give different results.

A vacancy rate is easy to quote and harder to read. This article explains the rental vacancy rate for someone buying a Queensland property to rent out. It covers what the rate counts, why two publishers can disagree about one place, whose label "healthy" is, and what an RBA research paper found about vacancy and rents in 2019. It also separates an area's rate from the weeks without rent you allow for on your own property. You won't find suburb vacancy figures here. For those, we point you to the publishers, and to the pages on this site that show a dated number with its source.

What a rental vacancy rate measures, and how it is calculated

A rental vacancy rate measures how many of an area's rental properties are listed as available for rent, as a share of all the rental properties there. That follows a Reserve Bank of Australia research paper published in March 2019. Multiply the fraction by 100 and you have a percentage.

The paper credits its vacancy series to the Real Estate Institute of Australia.

Australia's version is narrow. AHURI notes that most countries include all unoccupied dwellings in their vacancy rates, while Australia looks only at vacant rental properties. So an overseas definition won't describe an Australian figure.

The Census trips people up too. The ABS counts a private dwelling as unoccupied when no one was staying there on Census Night. A holiday home can land in that count. So a Census "unoccupied dwellings" share is a different measure from a rental vacancy rate.

Why two publishers give different rates for the same place

Two publishers can give different vacancy rates for one place because they count in different ways. AHURI's 2025 research found Australia has five commercial producers of rental vacancy rates. All of them work from surveys of property managers or from rental properties advertised online. The methods are often opaque, AHURI found, and different approaches give different outcomes. The report's summary page doesn't say which producer uses which method.

• 1Surveys of property managers
• 2Rentals advertised online

When AHURI compared the output of two producers, which it didn't name, average quarterly rates for smaller capital cities varied by up to 1.8%. That finding covers capital cities, so don't read it as a Queensland regional result.

SQM Research sets out its method on its vacancy rates page. It works from all the unique online listings it monitors over a calendar month, and uses only listings advertised for three weeks or more. The bottom half of its fraction is an estimate of the stock available for rent, built from Census dwelling and renter counts by postcode. The years and months between Census points are interpolated. So the top of SQM's fraction is a filtered count, and the bottom is an estimate.

Think about what that rule does. A rental advertised and let within ten days never reaches three weeks, so on SQM's stated rule it wouldn't be counted. That's our own reasoning from the rule, offered as an illustration.

So before you compare two vacancy figures, check they come from the same publisher and cover the same period. If they don't, the gap may come from the counting. And if a publisher doesn't set out its method, you can't tell which kind of count you're reading.

Tight, healthy or weak: whose label is it?

Each label belongs to the publisher that uses it, so "what vacancy rate is good" has more than one published answer. In its media release of 30 July 2026, the Real Estate Institute of Queensland (REIQ) classes rental markets as tight at 0 to 2.5%, healthy at 2.6 to 3.5% and weak at 3.6% and above.

In July 2025, REIQ said the healthy range supports adequate housing mobility and population growth. That's a view of a market, and it doesn't grade any one landlord's result.

On 5 December 2025, AHURI reported that the common understanding of a 3% vacancy rate as a market where supply and demand were balanced did not appear evidence-based.

So when a headline calls a market tight or healthy, check whose band it's using.

What an RBA paper found about vacancy and rents

The RBA's 2019 paper found the vacancy rate was the dominant influence on real rents in its model of the national housing market. Real rents are rents after inflation.

The model estimated that a one percentage point rise in the vacancy rate reduced the annual growth of real rents by 2 percentage points at first, and by 1.4 points in the long run. That's a national estimate from 2019 of how fast rents grew, and it can't be carried over to one suburb or one property.

The paper sets its own limit. Any projection of rents, it says, needs an assessment of how population growth, household size and zoning will evolve, and its model doesn't explore that.

Two dated observations show the link running both ways. An RBA Bulletin article from June 2023 described a rental market that had tightened since late 2021, as vacancy rates declined. On 28 May 2025, the ABS reported that growth in median rents had slowed across most states and territories since around late 2024. It called that consistent with increases in rental vacancy rates across the country.

Where Queensland vacancy figures are published

REIQ and SQM Research both publish Queensland vacancy figures. AHURI found that in most countries government produces vacancy data, while Australia relies on commercial organisations. AHURI also found that detailed outputs are only available for a fee. REIQ shows the split between headline and detail: its media release carries headline rates, and the full spreadsheet is for REIQ members.

• REIQ. Its quarterly Residential Vacancy Rate Report tracked 50 regions across the state in the June 2026 quarter.
• SQM Research. Its vacancy rates page lets you view data by postcode or by region.
• The Residential Tenancies Authority (RTA). It publishes median weekly rents by postcode and dwelling type, from new rental bonds lodged each quarter. Its quick finder ran to the April to June 2026 quarter when we read it on 13 October 2026. Its median rents releases list rents and bonds, and they don't list a vacancy rate.

For the numbers themselves, see Queensland rent growth and vacancy figures and the Sunshine Coast vacancy figure. Our Sunshine Coast market page explains why FAA Property has not published a vacancy rate of its own.

An area vacancy rate is not your property's vacancy

An area rate describes many rentals at once. Your property is one of them, and at any moment it's either let or empty. So the area number can't fill in your own vacancy line.

ASIC's Moneysmart, on a page last updated 29 September 2026, puts vacancy under the risks and limitations of property investment. There may be times, it says, when you have to cover the costs yourself without a tenant. Its advice: work out whether you could cover all expenses short term if you had no tenants for a while.

Moneysmart doesn't name a number of weeks, which leaves the allowance as your own assumption. Go back to the first fraction on this page: weeks without a tenant, over 52. You choose the weeks. Then you test whether your budget holds.

FAA Property's cash flow page carries a vacancy allowance as one line in its statement. For the whole picture, read how a cash flow statement for an investment property is built. To test your own number, change the rented-weeks input in the rental yield calculator.

What a vacancy rate cannot tell an investor

A vacancy rate can't tell you how one property will go. Its limits, in the publishers' own terms:

• It's one indicator. AHURI's lead researcher said there are risks in using it as a lone indicator of rental market health.
• A low rate may be old news. An area's rate may have been low for a long time.
• One quarter can mislead. REIQ's chief executive cautioned against reading too much into quarterly fluctuations, in the 30 July 2026 release.
• It doesn't project rents. The RBA paper says a projection needs an assessment its model doesn't explore.
• It's an area figure. It describes an area's rentals together, and says nothing about any one home.

For the records to check on one property, read due diligence on a Queensland investment property. Dwelling type is a separate question: see houses, townhouses and units compared for investors.
