How to Find High-Growth Suburbs: A Seven-Step Research Framework Using Free Public Data
By Tim AllenBuyer’s Agent and Director, IPS Buyer’s Agents
How do you find high-growth suburbs? Not by picking the suburb that grew fastest last year. No public data can pick next year’s top suburb, and markets turn quickly: Cotality’s national Home Value Index fell for a seventh straight month in October 2026, and Brisbane values fell 2.0% in that month alone.[1] The honest approach is to look for suburbs where several kinds of evidence line up, and to rule out the ones where they don’t. This framework uses seven checks and free public data, then runs them on one real Moreton Bay suburb.
Key takeaways
- Past growth doesn’t pick future growth. Cotality says virtually every suburb across Brisbane, Perth and Adelaide recorded a fall in values over the three months to October 2026.[1]
- Population growth isn’t price growth. Queensland’s fastest-growing areas in 2024–25, Ripley and Morayfield, both grew 15%,[2] and fast growth on the fringe can come with a lot of new supply.
- Read stock on market and vacancy together. In Morayfield’s postcode, listings for sale rose from 303 to 777 in the year to October 2026,[3] and the rental vacancy rate rose from 1.24% to 2.55%.[4]
- Check who lives there. In the 2021 Census, 43.9% of Morayfield’s homes were rented, against 33.1% across Queensland.[5]
Why last year’s growth won’t pick the next winner
Look for the highest property growth in Australia over recent years and you’ll land on the mid-sized capitals. Cotality says home values there recorded “extreme growth conditions” over the past six years, but are “now well and truly in a correction”, and that virtually every suburb across Brisbane, Perth and Adelaide recorded a drop in values over the three months to October 2026.[1] The same report puts the median time on market at 39 days, the highest since August 2020, with vendor discounting at 4.7% and capital city listings at their highest for this time of year since 2019.[1]
So a list of last year’s top performers tells you where prices went, not where they’re going. A framework won’t predict the next boom either. What it does is stop you buying where the evidence is weak, and help you compare suburbs on the same terms. Our Brisbane property market update for November 2026 covers the wider market.
Step 1: Follow the people
Population growth is the first filter, because more people need more homes. The Australian Bureau of Statistics publishes it every year, down to small areas. In 2024–25, Greater Brisbane grew by 58,200 people (2.1%) and the rest of Queensland by 39,700 (1.4%). Among the capitals, only Perth grew faster than Brisbane, at 2.4%.[2]
Within Queensland, the areas with the largest growth were Ripley in Ipswich (up 3,100 people), Caloundra West–Baringa on the Sunshine Coast (2,000) and Chambers Flat–Logan Reserve in Logan (1,800). The highest growth rates were in Ripley (15%), Morayfield in Moreton Bay (15%) and Greenbank–North Maclean in Logan (14%).[2]
Notice where they are: on the edges of the region, in growth corridors. People need somewhere to live, so in a growth corridor a fast-rising population usually means homes are being built fast too. That’s why population is a starting point, not an answer.
Next, find out how much new housing is planned. Councils publish their growth areas. In Moreton Bay, for example, the Morayfield South Emerging Community Area is expected to be the second largest future growth area and to one day contain 9,800 dwellings for 26,000 people,[6] and the Waraba Priority Development Area aims to provide 30,000 homes for about 70,000 people.[7] Our guide to checking property zoning and development applications shows how to find planned and approved development near a property.
Then look at what’s already for sale. SQM Research publishes free charts of total property listings by postcode, split by how long each listing has been advertised.[3] Stock that keeps rising tells you buyers aren’t absorbing what’s on offer. Supply is also a pocket-by-pocket question: as our FAQ puts it, pockets vary sharply on flood exposure, school catchments, body corporate health and new supply.
Days on market is the market telling you how strong demand really is. When we value a property for a client, we weigh settled sales in the same street or pocket, the current competing stock and days on market, and the land rate per square metre, as our FAQ explains. Cotality’s median time on market, 39 days in October, was the highest since August 2020.[1]
At suburb level, SQM’s listing charts split stock into homes listed for under 30 days, 30–60 days, 60–90 days, 90–180 days and over 180 days.[3] A growing share of listings over 90 days old means homes are sitting, and buyers have room to negotiate.
Vacancy rates show how quickly rentals are being taken. SQM’s postcode vacancy rate counts only rental listings that have been advertised for three weeks or more.[4] As a guide, the Real Estate Institute of Queensland calls a vacancy rate of 0 to 2.5% tight, 2.6 to 3.5% healthy and 3.6% or more weak.[8]
Watch the direction as well as the level. A rate that doubles in a year can still look low, but it tells you more rentals are competing for tenants. And as our FAQ says, tight vacancy supports income; it doesn’t fix a badly located or badly built property. Our guide to high-yield strategies in SEQ covers the income side.
The ABS Census QuickStats page for any suburb shows how its homes are held: owned outright, owned with a mortgage or rented, alongside the types of dwellings, the median rent and household incomes, each compared with the state.[5] The mix tells you who buys and rents there, which matters when you buy and again when you sell. QuickStats figures come from the 2021 Census, so in a fast-growing area the mix may have shifted since.
Infrastructure can change how a suburb works, but only once it’s funded and being built. Our rule, from our FAQ, is to buy near funded, visible infrastructure rather than near a logo, a promise or a rezoning that may never proceed. Our Moreton Bay infrastructure guide and Ipswich market trends for 2026 show what that looks like in two growth regions.
A suburb’s price only means something next to its neighbours’. Compare it with the suburbs around it on land value, housing type and distance to jobs, which is the logic behind the ripple-effect and proven-performer approaches in our guides to capital growth strategies in SEQ and area investment strategies. Our Brisbane suburbs list includes land values for all 177 suburbs.
Then rule out what no growth story can fix: flood exposure (see our Brisbane flood zone guide), zoning or overlays that limit the property, and for units, a weak body corporate.
Here’s what the free data said about Morayfield in Moreton Bay in November 2026. It’s an example of the method, not a recommendation either way:
| Check | What the data shows |
|---|---|
| People | Morayfield’s population grew 15% in 2024–25, one of the two highest rates in Queensland[2] |
| Planned supply | The Morayfield South Emerging Community Area is expected to one day contain 9,800 dwellings[6] |
| Stock for sale (4506) | 777 listings in October 2026, up from 303 in October 2025[3] |
| Listings over 90 days old | 258, up from 73 a year earlier[3] |
| Rental vacancy (4506) | 2.55% in October 2026, up from 1.24% a year earlier[4] |
| Who lives there (2021) | 43.9% of homes rented, 33.6% owned with a mortgage and 19.7% owned outright[5] |
| Housing type (2021) | 81.7% separate houses[5] |
Read together, the checks tell a mixed story. The population growth is real and among the fastest in the state.[2] But over the past year the number of homes for sale in the postcode more than doubled, the stock that has sat for more than 90 days more than tripled,[3] and the vacancy rate doubled, to the boundary between what the REIQ calls tight and healthy.[4][8] A large planned supply is still to come.[6] And in 2021, a larger share of homes were rented than across Queensland as a whole.[5]
None of that predicts where Morayfield’s prices go next. What it does is change the questions a buyer should ask: does this home compete with new estate stock, how does it compare with established streets nearby, and how long are similar homes taking to sell right now? Different geographies are involved, too. The population figure is for the ABS’s Morayfield statistical area, the listings and vacancy figures for the 4506 postcode and the Census figures for the suburb, so treat them as a picture, not a precise measurement.
Several of these checks come straight from how we work, as our FAQ sets out: we weigh competing stock and days on market when we value a home, we look for funded infrastructure rather than promises, and we compare pockets on flood exposure, school catchments, body corporate health and new supply. Tim Allen has personally inspected and negotiated all 128 properties IPS Buyer’s Agents has bought since 2023, including a family home in Albany Creek and an investment in Deception Bay. See our buyer’s agent services, fees and Moreton Bay suburb reports.
To find high-growth suburbs, stack the evidence: population, supply, days on market, vacancy, who lives there, funded infrastructure and value against the neighbours. When most of it lines up and nothing rules the property out, you have a suburb worth a closer look. When the checks pull in different directions, as they do in Morayfield right now, slow down and look harder. And in a falling market, be wary of anyone who claims to know the next boom suburb.

How do you find high-growth suburbs?
Look for suburbs where several kinds of evidence line up: population growth, a supply pipeline that isn’t swamping demand, homes selling quickly, tight rental vacancy, the mix of owners and renters, funded infrastructure and fair value against neighbouring suburbs. Then rule out flood, zoning and body corporate problems. No data predicts growth, so use the checks to compare suburbs and avoid weak ones.
Where has property grown fastest in Australia?
Over the past six years, Cotality says the mid-sized capitals recorded extreme growth conditions. By October 2026 they were in a correction: Brisbane values fell 2.0% that month and Perth’s fell 1.7%, and virtually every suburb across Brisbane, Perth and Adelaide recorded a fall over three months. Past growth is no guide to the next winner.
Does population growth push property prices up?
Not on its own. In 2024–25 the fastest-growing areas in Queensland, Ripley and Morayfield, both grew 15%, but fast growth in a growth corridor can come with a lot of new housing. In Morayfield’s postcode, listings for sale more than doubled in the year to October 2026. Check supply, days on market and vacancy alongside population.
What vacancy rate is considered tight in Queensland?
The Real Estate Institute of Queensland calls a vacancy rate of 0 to 2.5% tight, 2.6 to 3.5% healthy and 3.6% or more weak. SQM Research publishes free monthly vacancy rates by postcode, counting rental listings advertised for three weeks or more. Watch the trend as well as the level: a doubling in a year matters even if the rate still looks low.
Where can I find free suburb data?
The ABS publishes population growth for small areas each year and Census QuickStats for every suburb, including how homes are held. SQM Research has free postcode charts of vacancy rates and of listings by how long they’ve been advertised. Councils publish planned growth areas and development applications, and Cotality publishes monthly home value results for each capital.
Can anyone predict the next boom suburb?
No. Public data shows where demand and supply stand today, not where prices will go. Brisbane went from years of extreme growth to falling values in 2026, with virtually every suburb down over the three months to October. A research framework won’t pick the next boom, but it helps you avoid suburbs where supply is outrunning demand.
