NSW rental vacancy rate fell to 1.2 percent in September 2026, according to the latest Domain Rental Vacancy Report, adding further pressure to tenants as the supply of available properties remains tight across Greater Sydney and much of regional NSW.
Domain's monthly rental vacancy data shows the statewide vacancy rate dropped from 1.4 percent in August to 1.2 percent in September, well below the 3 percent level considered a balanced rental market. Greater Sydney recorded an even tighter rate of 1.1 percent, with many inner and middle-ring suburbs sitting below 1 percent.
The fall in vacancies comes despite an increase in new rental listings over the month, as demand continues to outstrip the supply of available homes. In Sydney's most competitive markets, rental properties are leasing within days of being listed, often attracting multiple applications.
Outside Greater Sydney, regional NSW also recorded low vacancy rates, with Newcastle at 1.0 percent, Wollongong at 1.1 percent and the Central Coast at 1.2 percent. The Illawarra region saw the sharpest monthly decline, falling 0.3 percentage points as workers continue to relocate from Sydney in search of more affordable housing.
The tight conditions are placing sustained upward pressure on rents. Domain data shows Sydney's median asking rent for houses has risen 8.2 percent over the past year, while unit rents have climbed 7.5 percent over the same period.
The ongoing rental squeeze reflects a structural shortage of housing across NSW. Building approvals for new dwellings remain below the levels needed to meet population growth, while the conversion of rental properties to short-term accommodation and owner-occupation has further reduced supply.
The Property Council of Australia has warned that without a significant boost to housing supply, rental conditions will remain challenging for tenants. The council is calling for faster planning approvals and greater investment in social and affordable housing to ease pressure on the private rental market.
With migration remaining strong and construction timelines stretched, analysts expect the rental market to remain tight heading into the summer months, when demand typically picks up. For tenants, the low vacancy rate means limited choice and continued competition for available properties.
