Affordable Housing Shortages

Introduction

Affordable housing shortages are no longer a peripheral policy concern in New South Wales — they are a deepening structural crisis with measurable human and economic consequences.

This in-depth summary draws exclusively on a landmark 2023 research paper published by the NSW Parliamentary Research Service, which synthesizes data, government programs, and expert recommendations to map the full scope of the challenge.

Whether you are a housing researcher, policymaker, student, or advocate, understanding this document is essential for grasping both the scale of the problem and the contested solutions being debated at the state and federal levels.

What Is Social and Affordable Housing? Understanding the Foundation

Before examining the data on affordable housing shortages, it is important to understand how the report defines its key terms.

Social housing is a broad category encompassing public housing (managed by the NSW Department of Communities and Justice, or DCJ), community housing (managed by not-for-profit providers), and Aboriginal housing (managed by DCJ or Aboriginal community housing providers).

Tenants in social housing typically pay between 25% and 30% of their income in rent, and eligibility is based on income limits and demonstrated housing need. Priority is given to those facing homelessness, domestic violence, or severe health conditions.

Affordable rental housing, by contrast, is built with government assistance or planning incentives and is rented to low- and moderate-income households at a discount — typically 20–25% below market rates.

It is primarily managed by community housing providers and some private investors, and unlike social housing, it has no systematic waitlist allocation process.

The Productivity Commission, as cited in the report, notes that while both housing types serve lower-income populations, social housing targets those who genuinely cannot access the private market, while affordable housing functions more as a "steppingstone" for those who might eventually transition to private renting.

These distinctions matter because affordable housing shortages manifest differently across the two categories, and the policy responses appropriate for each differ considerably.

The Scale of Affordable Housing Shortages in NSW: Key Statistics

The numbers in this report are stark. As of June 2022, NSW had 154,600 social housing dwellings — a 9% increase from 141,782 in 2013. Of these, 63% were public housing, 31% community housing, and 6% Aboriginal housing.

Despite this growth, the demand has outpaced supply dramatically:

• 57,558 applicants were on the NSW social housing waitlist as of 30 June 2022 — a 15% increase from the previous year.
• A 2022 UNSW City Futures Research Centre study estimated 221,500 low-income NSW households had unmet housing need at the time of the 2021 Census.
• By 2041, that figure is projected to grow to 320,700 households in NSW alone, and nearly 940,000 nationally.
• Affordable housing tenancies numbered just 10,441 across NSW in June 2021, a figure dwarfed by the scale of unmet need.

Wait times compound the picture further. General housing applicants in metropolitan Sydney can face waits of 5–10 years, or even longer depending on location and dwelling type. Priority applicants waited a median of 2.5 to 3.6 months, but general applicants waited 7 to 14 times longer.

The DCJ district of Southwestern Sydney recorded both the highest number of social housing dwellings (26,798) and the highest number of waitlist applicants (9,945), underscoring how affordable housing shortages are geographically concentrated in already-disadvantaged communities.

The Social and Economic Cost of Affordable Housing Shortages

Affordable housing shortages are not just a welfare issue — they carry measurable economic costs that ripple through communities and government budgets alike.

A 2022 report by the Centre for Urban Transitions at Swinburne University of Technology estimated that the total current social and economic costs of affordable housing shortages in NSW stood at $256 million per year, rising to $445 million per year by 2036. These costs include public and private sector expenditures related to:

• Homelessness, stress, and depression
• Domestic violence
• Reduced educational achievement
• Reduced disposable income
• Lower overall wellbeing

A separate 2022 report by SGS Economics projected even larger long-term costs, estimating that the national cost of underproviding social and affordable housing could reach $25 billion per year by 2051, once health, education, labor productivity, and crime costs are factored in.

The capital cost of addressing the national shortfall is equally sobering. A 2021 review estimated the net present value of building an additional 891,000 social and affordable housing dwellings across Australia over 20 years at approximately $290 billion.

These figures make clear that affordable housing shortages are not simply a social problem to be managed — they are an economic liability with compounding long-term consequences if left unaddressed.

NSW Government Policies Targeting Affordable Housing Shortages

The NSW Government has responded to affordable housing shortages through a combination of long-term strategies and targeted programs.

Key Strategies

The foundational strategy is Future Directions for Social Housing in NSW (2016), a 10-year plan structured around three priorities: more social housing, more pathways out of social housing, and a better experience for tenants.

It envisaged community housing providers managing 35% of all social housing within a decade and explicitly flagged affordable housing as a transition tool for people moving from social housing to the private market.

In 2021, Housing 2041: NSW Housing Strategy reaffirmed these goals, targeting rejuvenation of the social housing portfolio and growth in the affordable housing supply. A parallel 2018 strategy specifically addressed Aboriginal social housing.

Key Programs

The report documents four major programs aimed at alleviating affordable housing shortages:

1. Communities Plus — A $22 billion program launched in 2016 to redevelop Land and Housing Corporation sites, targeting up to 23,000 new social housing dwellings, 500 affordable housing dwellings, and 40,000 private dwellings over 10 years. By December 2021, around 2,393 social housing properties and 101 affordable homes had been completed.

2. Social and Affordable Housing Fund (SAHF) — A $1.1 billion fund to deliver over 3,400 social and affordable homes, with 30% targeted to regional NSW. As of December 2022, 3,069 new dwellings had been delivered.

3. Community Housing Innovation Fund (CHIF) — A $225 million program targeting approximately 1,000 social and affordable dwellings in collaboration with community housing providers.

4. Community Housing Leasing Program (CHLP) — A long-running program (since 2000) that funds providers to head-lease private market properties. In 2021–22, it provided $86 million to head-lease 5,940 properties.

Are These Programs Enough?

The report cites a 2022 Centre for Social Impact analysis suggesting that at current investment levels, the NSW Housing Register would decrease by only 371 applicants per year on average by 2040, and the waitlist would not drop below 45,000 until 2039. This assessment frames the existing policy response as insufficient to meaningfully close the affordable housing shortages gap within any near-term horizon.

Australian Government Initiatives Addressing Affordable Housing Shortages

At the federal level, the Australian Government's primary vehicle is the National Housing and Homelessness Agreement (NHHA), through which approximately $1.6 billion per year flows to states and territories. NSW received $498 million under this agreement in 2022–23.

Two major new initiatives announced in October 2022 are designed to deliver 40,000 homes nationally:

• Housing Australia Future Fund — A $10 billion investment fund whose returns would build 30,000 new social and affordable homes in its first five years.
• National Housing Accord — A $350 million commitment over five years from 2024–25 to support an additional 10,000 affordable homes.

The Housing Australia Future Fund Bill passed the House of Representatives but stalled in the Senate by the close of the March 2023 sitting period, reflecting ongoing political contention around the adequacy of these measures. The Greens called for $5 billion per year in dedicated social and affordable housing funding, arguing the current fund is insufficient to address the depth of affordable housing shortages.

Diverging Policy Recommendations on Affordable Housing Shortages

The Productivity Commission's Controversial Approach

The report gives significant space to the Productivity Commission's August 2022 review of the NHHA, which offered a markedly different diagnosis of affordable housing shortages from most other stakeholders.

The Commission declined to recommend targets for more social housing, arguing that waitlists are poor indicators of genuine need and that some eligible households could be housed more cost-effectively in the private market with financial support.

Instead, the Commission recommended piloting tenure-neutral, portable rental assistance — essentially extending Commonwealth Rent Assistance to public housing tenants and removing income-based rent settings — to give low-income renters more flexibility across housing types.

The Commission was equally critical of affordable housing subsidies, calling them "inflexible, inefficient and often unfair," and opposed inclusionary zoning requirements as well, arguing they add costs to developers and complexity to planning systems.

These recommendations were criticized by academics cited in the report. Pawson et al contended the Commission's approach would require a dramatic increase in rent assistance payments and failed to account for the broader social infrastructure value of well-managed social housing.

NSW Stakeholders: Bigger, Faster Investment

By contrast, advocacy bodies and peak groups called for much more aggressive action on affordable housing shortages. NCOSS called for the NSW Government to build 5,000 additional social housing dwellings per year for 10 years. An Equity Economics report estimated the cost at up to $2.6 billion per year, offset by $4.5 billion in annual economic benefits.

The Good Growth Alliance — comprising the Property Council of Australia, CHIA NSW, Shelter NSW, and Homelessness NSW — recommended growing social housing to 10% of total housing stock by 2050, establishing a $3 billion supplementary Social and Affordable Housing Fund, and mandating that 30% of development on former government land be designated as social and affordable housing.

Planning Mechanisms and the Limits of Regulation

The report examines a range of planning tools available to address affordable housing shortages. Under the Environmental Planning and Assessment Act 1979, developers can be required to contribute land or money for affordable housing, but only under specific conditions. A density bonus exists for residential developments that dedicate at least 20% of gross floor area to affordable rental housing for 15 years.

Uptake of these mechanisms has been limited. Only five metropolitan councils have developed contribution schemes under the Housing SEPP, and density bonus provisions have produced only about 2,000 affordable dwellings in Sydney since 2009. In November 2022, the NSW Government consulted on reforms including a 25% increase to density bonuses and a new approval pathway for large residential developments incorporating affordable or social housing.

Conclusion: Affordable Housing Shortages Demand Urgent, Sustained Action

Affordable housing shortages in NSW represent one of the most complex and consequential policy challenges of the current parliamentary term. This 2023 report from the NSW Parliamentary Research Service provides an authoritative, evidence-based overview of the problem — from the definitional foundations of the housing continuum to the granular district-level data on waitlists, from the inadequacies of current government programs to the sharply contested debate between supply-side advocates and the Productivity Commission's market-oriented approach.

What emerges clearly is that affordable housing shortages cannot be resolved through any single mechanism. Investment in new dwellings, planning reform, community housing sector capacity, and careful design of rental assistance systems all have roles to play.

What is less clear — and what the 58th Parliament must grapple with — is the pace, scale, and funding model required to genuinely close the gap between 221,500 households in unmet need today and a housing system that works for all NSW residents.

For researchers and advocates working on affordable housing shortages, this document remains an indispensable reference, synthesizing the best available data and policy thinking as of mid-2023.
