All new supply, in every suburb in the country, dated and on a map. Then we show you what it does to capital growth.
By Luke Metcalfe · Founder, Microburbs ResearchNot a sample, not the capitals, not the suburbs someone chose to cover. Every home in Australia sits on the map with the date its address was first recorded, so you can see exactly what has gone up around any address and roughly when.
Addresses as at the April 2026 national release, the most recent available. We refresh it as each release lands.
Mapping it is the first half. The second half is what it does to your money, and that is where the kind of building matters more than the amount.
Across the 4,912 Australian suburbs (of 15,026) that added at least 100 homes since 2016, the ones where the building was mostly apartments grew 2.8% a year less than the ones where it was mostly houses, from 2016 to 2026.
Sort those suburbs by how much went up and the gap between the busiest and the quietest is about a point a year. Sort them by what went up and the gap is nearly three times that.
Mostly apartments: Docklands, Melbourne. The weakest place we looked at, and it ran 16% a year behind Tarneit. Same decade, same amount of building, all of it apartments.
Mostly houses: Tarneit, Melbourne. Just as much building, but houses on new land instead of towers, 2016 to 2026, and it finished 16% a year ahead of Docklands.
The same pair shows up in Sydney. Zetland is three quarters new and nearly all apartments. Schofields had the same volume of building, in houses, and outgrew Zetland by about 11% a year over the same decade.
Before you bid, look at the map for the address you are buying. Ask what kind of building is going up nearby, not just how much. A lot of building is not automatically bad. A lot of apartment building is the thing that has gone with weaker growth.
Six things the research paper settles, including the parts that cut against a simple story.
Every suburb report now shows what has appeared nearby, when, and what kind it was.
