Brisbane’s Centenary corridor · buyer intelligence
Five years of gains. A new market after May.
Fourteen measured suburbs climbed sharply through 2021–26. Then Brisbane’s winter market turned: values fell, stock rose and clearance rates weakened. The opportunity is no longer simply finding the fastest-growing postcode—it is reading momentum, negotiation, tax treatment and parcel-level risk together.
Research snapshot: 4 October 2026The five-year performance map
The growth leaders are not the corridor’s most expensive suburbs. Sumner and Darra more than doubled, while Chelmer, Graceville and Sherwood lagged the city benchmark from much higher bases.
House growth from OnTheHouse/Cotality AVMs, mostly March–August 2026. Brisbane benchmark is Cotality dwelling growth to August 2026. Seventeen Mile Rocks is excluded because a comparable five-year figure was not found.
House value growth, five years
14 suburbs with comparable dataScale begins at zero. Values are percentages; the benchmark is a dwelling measure while suburb values are houses.
Budget night changed the forward equation
The 12 May 2026 federal budget altered investor tax settings, but the market response also reflects September’s 4.6% cash rate and tighter borrowing capacity. The evidence does not isolate the budget as the sole cause.
Policy from 1 July 2027
- Established homes: post-budget buyers can no longer offset rental losses against wages; losses are quarantined or carried forward.
- New builds: full negative gearing remains, directing the tax advantage toward added supply.
- Existing holdings: properties bought before 7:30pm AEST on 12 May 2026 are grandfathered until sold.
- Capital gains: the 50% discount is replaced by cost-base indexation plus a 30% minimum tax on net capital gains, with transition provisions.
- Buyer support: the expanded 5% Deposit Scheme, Help to Buy and First Home Super Saver settings continue.
Brisbane by early October
- −2.7% across winter; August was the third consecutive monthly decline.
- 91% of Brisbane suburbs recorded a value fall over the winter quarter.
- 19 → 28 days on market year on year, with median vendor discounting widening from 2.9% to 3.7%.
- 19–31% clearance-rate readings in September and early October, versus roughly 54–67% in comparable 2025 weeks.
- −20.1% first-home buyer mortgage demand over the year to August; overall demand fell 14.1%.
Suburb-by-suburb evidence
Use the five-year signal to establish the long view, then test the present sale against days on market, local rent evidence, flood exposure, building condition and the exact source date.
“Value” is generally a Cotality AVM; “sold median” is a transaction statistic. They answer different questions and are not interchangeable.
How a buyer’s agent should read it
The corridor is one market in name only. Price point, rail access, river exposure, housing type and sale depth produce materially different negotiating conditions.
Momentum and affordability met in the west
Darra, Riverhills and Jamboree Heights combined lower entry values with strong recorded growth. That does not make every listing good value: August’s city-wide lower-quartile weakness shows the affordable segment is no longer automatically protected.
Slower selling creates room—but asks why
Chelmer’s 47 days and Graceville’s 29 days sit above the Brisbane-wide 28-day reading. A longer campaign can create leverage; it can also signal flood, insurance, condition or pricing issues that require deeper due diligence.
Tax settings split new from established
For an investor buying after budget night, the treatment of an established house changes from July 2027. A new townhouse or apartment may retain full negative gearing, but planning potential and delivery risk must be verified—not assumed from a broad zoning proposal.
Thin markets distort the headline
Sumner’s $890,000 sold median came from only six sales and conflicts with a $1.366m Cotality AVM. In small suburbs, comparable sales and property attributes matter more than a single suburb median.

Sources, method & limits
This snapshot was compiled from pages available on 4 October 2026. The figures mix AVMs, sold medians and suburb-profile estimates. They should be used as market context, not combined into a single valuation model.
Domain vacancy figures are reported as found, but Sinnamon Park (6.27%) and Middle Park (5.44%) sit well above SQM’s Brisbane-wide 0.9% and may reflect a different method or data quality issue. Seventeen Mile Rocks has no verified five-year figure; several 12-month figures are older and are labelled.
