Do Mum and Dad Property Investors Actually House Australia?

Australia's housing debate often comes down to two familiar characters: the government that needs to fix the housing crisis, and the “greedy property investor” supposedly making it worse.

But that story leaves out an important question:

Who actually provides the homes Australians rent?

On a recent episode of the Teach Me About Property Podcast, Massey Archibald and Felise went back through Australia's social housing history and raised a provocative point.

Decades ago, governments played a much bigger role in providing housing.

Over time, that role changed.

And private property investors increasingly became part of the system housing Australian renters.

Understanding that history doesn't settle today's housing debate.

But it does make the debate a lot more interesting.

The Short Version

Australia's housing system didn't become dependent on private landlords overnight.

The historical picture discussed on the podcast shows:

• governments played a much larger role in housing construction after World War II;
• that contribution declined substantially over subsequent decades;
• public housing was also sold, redeveloped and demolished;
• private rental housing became increasingly important;
• population and housing demand continued to grow; and
• today's housing debate is therefore about more than simply “investors versus first-home buyers.”

The real question is bigger:

If Australia needs millions of rental homes, who is going to provide them?

Why Did Massey Start Looking Into Social Housing?

Because of something he kept seeing in the comments.

People were asking why the government couldn't simply build more housing.

At the same time, another phrase kept appearing:

“Greedy landlords.”

Massey explained:

“Investors are the enemy. Yeah. Greedy landlords. That's a really common term that pops up now.”

Rather than simply arguing with the comments, he started looking backwards.

How much housing did Australian governments once provide?

When did that change?

And if governments weren't supplying those homes anymore, who did?

As Massey put it:

“Sometimes we just need a history lesson.”

He's right about one thing: Australia's current housing system makes much more sense when you understand how we got here.

How Much Housing Did Government Once Build?

The biggest contrast in Massey's discussion comes immediately after World War II.

Australia was entering the baby-boom era.

Servicemen were returning home.

Families were forming.

The country needed housing.

According to the historical figures Massey discussed on the podcast, social housing represented around 26.1% of new housing construction during that post-war period.

That's more than one in four new homes.

Massey described the government's position at the time as essentially:

“We are the government. We're gonna provide the housing.”

Whether you agree with that model or not, the scale is striking.

Government wasn't a minor participant.

It was a major housing provider.

And then that began to change.

What Happened to Australia's Social Housing Construction?

It fell.

Substantially.

Massey described social housing's share of new construction falling from around 26.1% in the post-war period to roughly 6.3% by the early 1970s, based on the historical data he had researched for the podcast.

He said it eventually reached around 1.5% of new builds at its low point in the 2010s.

That's an enormous structural change.

The exact historical series deserves careful interpretation because public, community and social housing definitions and reporting have changed over time.

But the broad direction behind Massey's argument is clear:

Government's role as a direct provider of new housing became much smaller than it once was.

But Didn't Governments Keep Building Public Housing?

Yes.

This is where the story gets more complicated.

Governments can build social housing while also selling, demolishing or redeveloping existing stock.

So looking only at the number of new homes built doesn't necessarily tell you whether the total pool of public housing is growing.

Massey focused heavily on this distinction.

“The government adds to the stock, but they also subtract from social housing.”

In the figures discussed on the podcast, he said that around the early post-war period there were approximately 8,740 new dwellings built, compared with around 500 sold or demolished.

By the early 1980s, the picture he presented had changed dramatically.

For the 1981–84 period, Massey cited an average of approximately 8,562 homes built, compared with around 16,621 sold or demolished.

His conclusion:

“We're now below.”

In other words, his argument isn't simply that governments built fewer homes.

It's that at points in the historical series he examined, additions were being outweighed by removals.

Why Would Governments Sell or Demolish Social Housing?

There isn't one reason.

This is where we need to separate the historical trend from Massey's interpretation of why it happened.

Social housing can be sold, demolished or redeveloped for many reasons.

Housing can become old or unsuitable.

Large estates can be redeveloped into different housing mixes.

Land can be sold.

Governments can change their housing priorities.

Responsibility can shift toward community housing providers.

And public assets can be redeveloped as cities change.

Massey's interpretation is much stronger.

He argues that governments progressively decided they didn't want to carry the same direct responsibility for housing provision.

“We need someone else to pay for this.”

And who does he believe increasingly filled that role?

Private property investors.

Did Mum-and-Dad Investors Replace Government Housing?

Not literally.

Private rentals and social housing serve different purposes and shouldn't be treated as interchangeable.

Social housing exists specifically to provide secure, affordable housing to eligible households, including people who may not be well served by the private rental market.

A privately owned investment property is different.

The rent is generally market-based.

Eligibility isn't determined like public housing.

Tenure arrangements differ.

The owner's objectives are different.

So it would be inaccurate to say private investors simply “replaced” social housing.

But Massey's broader point is worth exploring.

Australians continued needing rental homes while government's direct role in providing housing declined from its post-war highs.

Someone still had to own the homes being rented privately.

And increasingly, that meant private landlords.

In Australia, many of those landlords are ordinary individual investors rather than giant institutional property companies.

That's the part of the housing conversation Massey believes gets overlooked.

Why Does Australia Need Property Investors at All?

Because not every household owns a home.

Some people can't afford to buy yet.

Some don't want to.

Some are studying.

Some have recently separated.

Some move frequently for work.

Some are new to an area.

Some need flexibility.

And some may eventually become homeowners but need somewhere to live in the meantime.

Those households need rental properties.

Social and community housing provide part of that accommodation.

The private rental market provides another major part.

That's why simply saying “get rid of investors” doesn't answer the housing question.

You then have to ask:

Who owns the homes renters live in instead?

That's the question at the centre of Massey's argument.

Are Property Investors Really the “Bad Guys”?

That's too simplistic.

There are legitimate criticisms of Australia's housing and investment system.

Investors compete with owner-occupiers for some properties.

Tax settings can influence investor behaviour.

Poor landlords exist.

Poor-quality rentals exist.

Housing affordability is a genuine problem.

And renters deserve appropriate protections.

But none of those points changes the fact that private landlords also provide housing used by millions of Australians.

Massey takes issue with the idea that investors can be reduced to one stereotype:

“You are the enemy. You are the bad guy.”

His argument is that this ignores how Australia's housing system evolved.

For decades, governments reduced their relative direct role in housing provision while private investment became deeply embedded in the rental market.

You can debate whether that was the right model.

But you can't understand today's rental system without acknowledging it.

Could Government Just Start Building More Housing Again?

In theory, governments can increase their housing investment.

In practice, building at scale isn't as simple as announcing a target.

You need land.

Planning.

Infrastructure.

Finance.

Materials.

Builders.

Electricians.

Plumbers.

Carpenters.

Project managers.

And time.

Massey raises another important constraint during the episode:

Australia's construction workforce.

He argues that if government dramatically expands construction, it's drawing from many of the same trades and resources already used by private developers.

His question is simple:

“The Australian government's gonna get into competition with the private sector for the trades... How does that work?”

That doesn't mean government shouldn't build housing.

It means additional housing still has to be physically built by somebody.

If labour and construction capacity are already constrained, simply increasing the amount of money chasing that capacity doesn't automatically create thousands of additional homes overnight.

Why Is This Bigger Than a Landlord Debate?

Because Australia's housing challenge is ultimately a supply problem.

We need enough appropriate housing for the people who live here.

That housing can come from different places:

Public housing.

Community housing.

Owner-occupied homes.

Private rental properties.

Build-to-rent developments.

New houses, townhouses and apartments.

Each serves a different part of the market.

The problem with turning the debate into “government good, investors bad” — or the reverse — is that it distracts from the practical question:

How do we create enough housing?

That's much harder to fit into a social media comment.

But it's the question that matters.

What Does This Mean for Mum-and-Dad Property Investors?

It means understanding the role you actually play.

An investment property is still an investment.

You're taking financial risk with the expectation of a return.

You're not providing a charity service.

At the same time, your asset is somebody else's home.

Both things are true.

That means successful property investment shouldn't just be about buying something and collecting rent.

Good investors need to understand maintenance, property management, financing, insurance, tenancy obligations, cash flow and the responsibility that comes with providing a home.

The housing debate becomes more productive when we stop pretending investors are either heroes or villains.

They're participants in a housing system Australia has spent decades creating.

What Does This History Teach Us About Australia's Housing Crisis?

Probably that there isn't one person to blame.

Australia's housing system is the result of decisions made over generations.

Governments changed how they approached public housing.

Private landlords became increasingly important to rental supply.

Population grew.

Cities expanded.

Construction became more expensive.

Land became more expensive in many desirable locations.

Planning and infrastructure created constraints.

Interest rates changed.

Housing preferences changed.

And now we're trying to solve all of those problems at once.

That's why Massey's history lesson is valuable even if you don't agree with every conclusion he draws from it.

It forces us to ask a better question.

Not:

“Whose fault is the housing crisis?”

But:

“What kind of housing system are we actually trying to build from here?”

Because renters still need homes.

First-home buyers need somewhere they can afford.

Vulnerable Australians need appropriate social housing.

Developers need projects that are viable to construct.

And private investors need enough confidence to supply rental properties where they're needed.

Australia's housing problem isn't going to be solved by choosing one of those groups and declaring them the enemy.

It will be solved — if it can be solved — by figuring out how they fit together.

Frequently Asked Questions

What is social housing in Australia?

Social housing is generally affordable rental housing provided for eligible households by governments or community housing organisations. It includes public housing and community housing. It serves a different purpose from privately owned rental property, although both form part of Australia's broader housing system.

Did Australian governments used to build more public housing?

Government played a particularly significant role in housing construction in the decades following World War II. The historical figures discussed by Massey on the TMAP podcast show the relative contribution of social housing construction declining substantially from its post-war level over subsequent decades.

Did private property investors replace public housing?

Not directly. Social housing and private rental housing serve different functions. However, as Australia's private rental sector expanded and government's relative role as a direct housing provider declined from post-war levels, private landlords became increasingly important providers of rental accommodation.

Why can't the Australian government simply build more houses?

Government can fund and build more housing, but construction is constrained by factors including available land, planning, infrastructure, labour, materials, costs and development capacity. Large public construction programs can also draw on the same builders and trades required by private residential projects.

Are property investors responsible for Australia's housing crisis?

Australia's housing challenges have multiple causes and can't reasonably be attributed to one group. Housing supply, population, planning, construction costs, finance, government policy, social housing, investor activity and local market conditions can all affect housing availability and affordability.
