Rental Affordability in Australia: What the Numbers Show and Why Delivery Matters More Than Ever

The 30 per cent threshold is the standard measure of rental stress in Australia: when a household spends more than 30 per cent of its gross income on rent, it is considered to be in housing stress — a point at which other essentials, food, transport, healthcare, are being crowded out.

By that measure, rental stress is no longer exceptional in Victoria. It is the lived experience of hundreds of thousands of low-income households, key workers, regional renters, pensioners, and anyone whose income falls below the median. Understanding what the data actually shows — and being honest about what it means — is the starting point for understanding what's being asked of the organisations building social and affordable housing.

What the Data Shows

The clearest annual picture comes from the National Shelter–SGS Economics and Planning Rental Affordability Index (RAI), now in its eleventh year. The Index scores rental affordability on a scale where 100 represents the point at which the average household spends exactly 30 per cent of its income on rent. Scores below 100 mean rental stress for the average household. Scores above 100 mean the average household is spending less than 30 per cent — though this tells you little about what people on lower incomes experience.

For greater Melbourne, the 2025 RAI showed median rent of $570 per week consuming 25 per cent of the median renting household's income of $116,640 — up from 19 per cent just four years earlier. Melbourne recorded a 22 per cent decline in rental affordability between 2021 and 2024, the steepest sustained fall in the city's history. Affordability stabilised in 2025, but stabilisation at a record low is not recovery. The affordable corridor that once stretched from Footscray to Meadow Heights — suburbs within 5 to 10 kilometres of the CBD that were accessible to average-income renters before 2020 — has now almost entirely vanished.

For regional Victoria, the picture is worse. The average renting household in regional Victoria now spends 28 per cent of its income on the median rental — and that is the average. In areas like Wodonga, central Bendigo, Warrnambool, and Apollo Bay, the RAI has dropped below 100, meaning the average household is already in stress. Coastal communities that were classed as affordable before 2020 now record median rents that exceed 30 per cent of average incomes. Regional rental affordability has declined by 20 per cent over the five years since Victoria's Big Housing Build was announced.

For low-income households, the numbers are severe by any measure. A single person on JobSeeker in Melbourne faces rents classed as Critically Unaffordable. A single pensioner faces Extremely Unaffordable rents. A single part-time worker on parenting benefits faces rents that consume 46 per cent of income in regional Victoria. A full-time hospitality worker in Melbourne would need to spend 42 per cent of their income on rent. The 30 per cent threshold — already a point of genuine hardship — is a number many of these households can only see in the rearview mirror.

Nationally, the Australian Institute of Health and Welfare estimated that in 2024–25, 1.26 million low-income households were in financial housing stress, spending more than 30 per cent of their disposable income on housing.

Victoria's Particular Position

Within this national picture, Victoria holds a specific and troubling distinction: it has the lowest proportion of social housing of any state or territory in Australia, at approximately 3 per cent of total housing stock.

The consequences of that structural underinvestment are visible in the data. As of March 2025, 66,117 people were on the Victorian social housing waitlist — a 7.4 per cent increase in a single year. More than 10,000 Victorians every month access homelessness support services because of housing affordability stress. Over 13,000 access those services each month because of family violence. One third of all people seeking homelessness assistance in Australia are in Victoria — a state that accounts for around a quarter of the national population.

The community housing sector in Victoria has grown, from 14,236 homes in 2016 to 19,625 in 2025. That growth matters. But it is happening against a backdrop where the waitlist is growing faster than the housing supply, where state investment in housing and homelessness services is $399.80 per person — below the national average despite Victoria representing a disproportionate share of demand — and where the private rental market offers increasingly little relief to households on low and moderate incomes.

In 2024, only 1.4 per cent of rental listings in Victoria were affordable to households on income support. For households earning the minimum wage, 21.6 per cent of listings were affordable — down from 25.6 per cent the year before.

What This Means for Housing Providers

For community housing providers, aged care operators, SDA developers, and crisis accommodation services, the scale of unmet need described by this data is not abstract. It is the population they exist to serve.

The people on Victoria's social housing waitlist are not a homogeneous group. They include elderly Victorians who cannot afford private rent on a pension. Workers whose wages have been outrun by the cost of living near their job. Single parents who cannot cover rent and childcare simultaneously. People experiencing domestic violence, for whom the cost of private rental is not just financial but safety-critical. People with disability who cannot access housing in the private market that meets their support needs.

For each of these cohorts, the housing the sector builds has different requirements. An aged care facility that gets design wrong doesn't just fail a compliance standard — it fails the people it was built for, for decades. An SDA dwelling that doesn't meet the participant's functional needs exposes them to ongoing dependence and indignity. A community housing project delivered with defects and incomplete commissioning isn't a technical shortfall — it's a problem that a low-income family on a waiting list has to live with.

The scale of need described by the rental affordability data raises the stakes for everything about delivery. When housing is this scarce and this necessary, there is no margin for projects that stall at procurement, feasibility that collapses because of stale cost data, or buildings handed over with unresolved defects. Every project that doesn't get built or doesn't get built to standard is a household that stays on a waitlist or stays in stress.

The Supply Response Is Not Keeping Pace

The federal government's National Housing Accord targets 1.2 million new homes by 2029. The National Housing Supply and Affordability Council projects around 938,000 are likely to be delivered — approximately 78 per cent of the target. In the first year of the Accord, 174,030 homes were completed, 27.5 per cent below the annual rate required.

The Housing Australia Future Fund has committed 279 contracts supporting 18,650 social and affordable homes, with 889 completed and 9,501 under construction as of November 2025. The fund's Round 3, opened in January 2026, targets a further 21,350 homes. These are meaningful commitments. But they are being made in a market where construction costs are 30 per cent higher than pre-COVID, contractor insolvencies remain elevated, and feasibility for higher-density projects — the typology most likely to deliver social and affordable housing in locations where it's needed — remains under sustained pressure.

For community housing providers and other mission-driven organisations trying to navigate this environment, the gap between the scale of need and the pace of delivery is not a policy abstraction. It is the daily pressure of trying to build more homes when it costs more, takes longer, and requires more governance capacity than it did five years ago.

What Closing the Gap Requires

The rental affordability data tells you the size of the need. It doesn't automatically tell you what to do about it. But for the organisations in this sector, a few things are clear.

The projects that get built are the ones with strong governance from the start — feasibility that reflects current market conditions, cost plans that are updated at each decision point, procurement strategies that account for contractor market risk, and delivery teams that stay on the project through to practical completion and beyond. In a market where everything about delivery has become harder, the organisations that invest in their delivery capability are the ones that get homes built.

The projects that don't get built are the ones that run on outdated assumptions, hand off between advisory teams at each project phase, treat contingency as optional, or get to procurement and find the numbers don't hold. The sector cannot afford that failure rate, given what the waitlist figures represent.

MakeSpace works alongside community housing providers, aged care operators, and specialist accommodation organisations to set projects up to run well — from feasibility through to the end of the defects liability period. If you're planning a project and want to talk through what delivery support looks like, we'd be glad to have that conversation. Get in touch.

MakeSpace is a not-for-profit project advisory and client-side delivery consultancy, and a subsidiary of Unison Housing. Retained earnings are reinvested into the housing sector — so each project we help deliver helps fund the next.
