What we're measuring
The Census records who owns each rented home. In the 2021 Census tables, the relevant categories are "Rented: State or territory housing authority" (usually called public housing) and "Rented: Community housing provider". Together they make up most social housing.
You can find them in the Census General Community Profile (table G37, tenure and landlord type by dwelling structure), which is published for areas down to a few hundred residents. Suburb-level QuickStats pages give the overall rented share, but you need the fuller tables for the landlord breakdown.
For context, the Australian Institute of Health and Welfare reports social housing made up 4.0% of all households in 2025, down from 4.7% in 2013. The 2026 Census was held on 11 August 2026, and the ABS plans to release most results in June 2027. Until then, 2021 is the latest Census data.
Why it affects a market
House prices are set by competition between buyers, and in most established suburbs the deepest pool of buyers is owner-occupiers. Homes owned by a housing authority are held for the long term and rarely sold on the open market.
So when a pocket has a high concentration of them, a few things tend to follow:
- Fewer sales. Less of the housing stock is ever for sale, so there's less evidence of value and less market activity.
- A smaller buyer pool at resale. If owner-occupiers are a smaller share of the area, fewer of them are looking to buy into it.
- Slower price growth in some cases. With less competition, prices can lag nearby areas with similar homes.
None of this is a judgement about residents. It's arithmetic about how many homes trade and who buys them.
Why a small share is normal, and fine
Almost every suburb has some social housing, and that's how it should be. Mixed communities are normal, and homes spread through a neighbourhood are barely visible to the market at all. A suburb at or near the national average isn't a concern on this measure.
What we look at is concentration: a share well above the surrounding area, especially when it's clustered in one part of a suburb.
Why the pocket matters more than the suburb
A suburb average can hide a lot. As an illustrative example, a suburb with a 6% share might have one pocket where it's 30% and several where it's close to zero. The houses in those pockets can behave like different markets.
That's why we read this measure at pocket level, the hexagon of a few hundred homes around a property, as well as across the suburb. A house two streets from a large cluster may be in a very different position from one inside it.
Redevelopment can change things
Housing authorities don't stand still. States renew older estates, often replacing them with a mix of social, affordable and private homes. That can change a pocket substantially:
- More owner-occupiers. New private homes bring new buyers into the area.
- Better amenity. Renewal often comes with upgraded parks, streets and services.
- More supply, at least for a while. A large number of new homes can compete with established houses for buyers and tenants.
- Years of construction. Timelines are long and plans change.
So a high share today isn't a permanent label, and a low share isn't guaranteed to stay low. We check state and council plans for any area we look at. Plans are not promises, and we don't buy on the strength of one.
How we use it
A high public housing share is one of our five hard suburb vetoes, alongside a suburb that's overheated, peaking, declining or has a yield too low to hold. The veto is about concentration and what it does to market depth, not about whether social housing is present. At pocket level, we look at where any concentration sits relative to the property.
We read it alongside everything else: who buys in the area, how many homes sell each year, how long they take to sell, and what's planned. Our guide to choosing a suburb and pocket shows how these fit together, and how we read the data explains our sources and their limits.
If you already own investment property and want to know how its pocket looks on these measures, our free Portfolio Health Check is a good place to start.
