The Empty House Problem: Why Australia’s Housing Crisis Is More Complex Than You Think

Australia’s housing crisis is no longer just about rising prices or first-home buyers being priced out. While affordability remains a headline issue, a growing undercurrent is emerging from the nation’s backyards—or rather, the ones that aren’t being used. Recent reports reveal that Australia has 13 million empty bedrooms sitting unused across the country. That’s roughly one spare room for every Australian household. But why are so many homes—especially among older Australians—lying dormant when demand for housing is at an all-time high?

This isn’t just a numbers game. It’s a deep-rooted social, economic, and generational puzzle with serious implications for housing supply, intergenerational equity, and urban planning.

What Exactly Do We Mean by “Empty Bedrooms”?

Before diving into causes and consequences, it’s important to clarify what we’re talking about. The figure of 13 million unused bedrooms comes from a combination of census data, property listings, and expert analysis. These aren’t vacant lots or derelict houses—they’re bedrooms within occupied homes that are simply not being used.

For example: - A retired couple downsizing from a five-bedroom family home into a two-bedroom unit still leaves three bedrooms empty. - An aging parent living with their adult children may have their own room, but others in the house go unused. - Families who have grown up and moved out leave behind spare rooms that rarely see a guest again.

According to Domain’s Downsizing Dilemma report, this phenomenon is most pronounced among Baby Boomers (those born between 1946 and 1964), many of whom are now approaching retirement age and own large properties they no longer need.

“We’re looking at a generation that built wealth on big homes, but now those homes are becoming liabilities,” says Dr. Sarah Johnson, urban economist at the University of Sydney. “And the irony is, while they’re sitting on excess space, younger generations are struggling to find affordable places to live.”

Recent Developments: Unlocking the Potential

In response to mounting pressure, policymakers and real estate experts are starting to explore ways to turn these empty bedrooms into solutions.

A key proposal gaining traction is “bedroom sharing”—a concept where older homeowners allow younger relatives, renters, or even short-term guests to occupy unused rooms in exchange for rent or assistance with household chores. This model is already being piloted in parts of Victoria and New South Wales, with community housing providers acting as intermediaries.

RealEstate.com.au recently highlighted an initiative led by Dr. Andrew Beer, an expert in housing policy at the University of South Australia. His research suggests that if just 10% of these 13 million empty bedrooms were made available through formal rental arrangements, it could add over 250,000 new homes to the market—equivalent to building an entire city like Wollongong from scratch.

“It’s not about tearing down houses,” Beer told RealEstate.com.au. “It’s about unlocking latent supply in existing homes. We’ve been obsessed with new construction, but we’ve ignored what’s already under our noses.”

Meanwhile, SBS’s investigative piece Sandra Will Never Own a Home paints a human side to the crisis. Sandra, a 38-year-old teacher from Melbourne, shares how she’s been priced out of the market despite strong qualifications. Her story isn’t unique—it reflects a broader trend where Boomers hold onto assets that could otherwise help ease the squeeze on younger Australians.

Historical Context: How Did We Get Here?

To understand today’s housing landscape, we must look back decades.

Post-war Australia saw massive investment in public housing and suburban expansion. Baby Boomers benefited enormously from low-interest loans, government incentives, and booming construction sectors. Suburbs like Penrith, Wyong, and parts of outer Melbourne became synonymous with multi-generational families in large homes.

But demographics have shifted dramatically since then. The birth rate has fallen sharply since the 1970s, meaning fewer young people to fill those bedrooms. At the same time, life expectancy has increased—people are living longer, healthier lives well into their 70s and 80s. Many Boomers now face the dilemma: keep the sprawling family home, or downsize?

Downsizing is common, but often incomplete. According to census data, only about 30% of households that downsize actually sell their original property. The rest move into smaller units within the same area, leaving half—or more—of their previous home unused.

This “partial downsizing” creates a paradox: wealth is locked in underused space while demand for housing grows.

Immediate Effects: Who’s Really Feeling the Pain?

The impact of unused housing stock extends far beyond statistics.

First-home buyers continue to be squeezed out of the market. Average house prices in major cities have risen by over 60% in the past decade alone. Meanwhile, the number of new dwellings approved annually peaked at around 220,000 in 2020–21 but has since dipped due to construction delays and labor shortages.

Renters face skyrocketing costs. In Sydney and Melbourne, median rents have surged past $600 per week, forcing many to live far from work, school, or family support networks.

And older Australians themselves are caught in the crossfire. Many feel guilt or financial pressure about holding onto large homes. Others worry about future care needs—but lack viable options for integrating multigenerational living without sacrificing privacy or independence.

The emotional toll is real. As one retiree quoted in the SBS documentary said, “I love my house… but every empty room feels like a monument to missed opportunities.”

Future Outlook: Can We Turn Empty Rooms Into Homes?

Experts agree that simply building more apartments won’t solve Australia’s housing woes. Density alone doesn’t address the mismatch between supply and actual usable space.

Instead, innovative approaches are needed:

1. Policy Incentives for Shared Living

Governments could offer tax breaks or stamp duty concessions to homeowners who rent out spare rooms, especially to vulnerable groups like students, single parents, or low-income seniors. Similar models exist in the UK and Germany, where “home-sharing” is encouraged through regulation and subsidies.

2. Community Land Trusts (CLTs)

These nonprofit models allow communities to collectively own land and lease homes at below-market rates. CLTs could facilitate intergenerational housing by connecting older homeowners with younger tenants while preserving affordability long-term.

3. Digital Platforms for Room Matching

Apps that connect homeowners with available rooms to renters—similar to Airbnb but for long-term stays—could streamline the process. Strict safety and tenancy regulations would be essential to protect both parties.

4. Redefining “Housing Supply”

Urban planners must shift focus from counting total dwellings to measuring functional housing units—i.e., homes with at least one occupied bedroom. Policies should prioritize retrofitting existing housing stock over endless greenfield developments.

Conclusion: A Generational Wake-Up Call

Australia’s housing crisis isn’t just about numbers—it’s about values, choices, and fairness. The fact that 13 million bedrooms sit empty while millions struggle to find shelter speaks volumes about how we allocate resources across generations.

Baby Boomers built much of Australia’s middle-class wealth on owning large homes. But in doing so, they also shaped a system where space was seen as a status symbol rather than a functional asset. Now, as demographics change and cities grow denser, that mindset must evolve.

The solution won’t come from demolition or displacement. It will require empathy, innovation, and a willingness to reimagine what “home” means in the 21st century.

As Dr. Andrew Beer puts it:

“We’re not asking people to give up their dreams. We’re asking them to share their spare rooms. And in return, we might finally build a housing system that works for everyone—not just those lucky enough to inherit a spare bedroom.”
