Australia’s rental market has recorded a modest improvement in available housing, although vacancy rates remain exceptionally low across most capital cities. New figures suggest rental conditions may be beginning to ease gradually, but the shortage of available properties continues to create challenges for tenants seeking accommodation.

According to SQM Research, the national residential vacancy rate increased to 1.4% in September 2026, compared with 1.3% in August. While the movement represents a slight improvement in rental availability, it remains well below the levels generally associated with a more balanced rental market.

The September figures show approximately 42,290 vacant dwellings across Australia, an increase of around 1,250 properties compared with the previous month. This additional supply provides some relief, but it is relatively small when considered against the size of the national rental market.

The improvement was partly driven by higher vacancy rates in Sydney and Melbourne, where rental availability increased during September. Sydney recorded a vacancy rate of 1.8%, while Melbourne reached 1.9%.

Canberra also recorded a vacancy rate of 1.9%, making it the only other capital city with a rate above 1%. These results contrast sharply with conditions in Brisbane, Perth, Adelaide, Darwin and Hobart, where vacancy rates all remained below 1%.

The differences between capital cities demonstrate how rental conditions can vary considerably across Australia. While some metropolitan markets are showing early signs of easing, others continue to experience extremely limited housing availability.

Brisbane recorded approximately 3,222 dwellings available for rent during September. Although this represents a substantial number of properties in absolute terms, availability remains constrained relative to the size of the city’s rental population.

Perth recorded only around 1,189 vacant rental dwellings, while Adelaide had approximately 948 available properties. Conditions were even tighter in the smaller capital cities, with Darwin recording just 162 vacant dwellings and Hobart only 127.

These figures highlight the difficulty tenants can face when searching for suitable accommodation, particularly in locations where available properties are concentrated within specific suburbs or price ranges.

A low vacancy rate can increase competition between prospective tenants, especially for well-presented properties close to employment centres, schools and public transport. Households may need to broaden their preferred locations or adjust their accommodation requirements when suitable listings are limited.

For tenants already occupying rental properties, tight market conditions can also create uncertainty when leases approach renewal. Limited alternative accommodation may reduce flexibility for households considering a move because of changing employment, family circumstances or housing costs.

SQM Research managing director Louis Christopher says the modest increase in the national vacancy rate may indicate the beginning of a gradual improvement in rental conditions.

However, the latest figures are not yet sufficient to establish a sustained recovery in rental availability. A single monthly increase can reflect seasonal changes, variations in leasing activity or a temporary rise in properties advertised for rent.

Christopher has also identified the performance of unit rents as an important trend to monitor during the spring leasing season. Continued softening in apartment rents could eventually contribute to slower rental growth across the broader market.

This distinction matters because rental vacancy rates and rental prices do not always move at the same pace. Even when more properties become available, advertised rents may remain elevated if tenant demand continues to exceed supply in popular locations.

Likewise, changes in the availability of apartments may not immediately influence detached house rentals, particularly where family-sized accommodation remains scarce.

For property investors, the September results provide a reminder that rental markets should be assessed at a local level. National vacancy figures can establish a general direction, but individual suburbs and property types may experience substantially different conditions.

Investors considering a purchase should examine current rental listings, comparable leasing transactions, local employment drivers and the pipeline of new residential development. These factors can help establish whether rental demand is likely to remain sustainable.

Existing landlords should also recognise that extremely low vacancy rates do not eliminate the importance of competitive pricing and property presentation. A well-maintained dwelling offered at an appropriate rental level is generally better positioned to attract suitable tenants and minimise periods without rental income.

For policymakers and housing providers, the continued shortage of rental accommodation reinforces the importance of increasing housing supply while addressing barriers to new residential development.

Population growth, household formation, construction activity and investor participation can all influence the availability of rental properties over time. Improvements in one market may therefore occur alongside continuing shortages elsewhere.

The September 2026 results offer a tentative indication that rental conditions are beginning to ease, particularly in Sydney and Melbourne. Nevertheless, with the national vacancy rate at just 1.4% and five capital cities below 1%, Australia’s rental market remains under considerable pressure.
