The Cotality (formerly CoreLogic) Home Value Index for May 2026 came in at +0.2 per cent across the combined capitals, the weakest monthly print of the cycle so far. The annual figure is now 8.1 per cent combined capitals and 10.4 per cent combined regions, with the monthly trend continuing to soften as the May 6 RBA hike works through.
The headline hides the same two-speed story the April data showed, but the gap is now wider. Sydney values fell 0.7 per cent in May (the fifth consecutive monthly decline), Melbourne fell 0.6 per cent (sixth consecutive), while Perth posted +2.0 per cent, Brisbane +1.0 per cent, and Adelaide +0.9 per cent. The combined-capital median moved to $1,016,200, broadly flat against April.
Sydney and Melbourne: the cycle confirms
Six consecutive months of decline in Sydney moves the read from "softening" to "confirmed correction". The cumulative six-month fall is now 3.9 per cent, with vendor discounting at 3.4 per cent and auction clearance rates in the high-50s. Listings volumes are up 18 per cent year-on-year, which structurally weighs on price.
Melbourne is one month behind Sydney but tracking the same path: five months of decline, cumulative fall of 3.1 per cent, listings up 14 per cent year-on-year. Cotality's May commentary noted that the Melbourne outer-metro postcodes (particularly the building-industry-heavy West and Northwest) are softening faster than the inner-ring established suburbs.
Perth: still rising, but watch the leading indicators
Perth posted +2.0 per cent in May, taking annual growth to 22 per cent. That is the strongest annual growth rate of any Australian capital in 2026 and one of the strongest in the past 20 years. The drivers are structural: low listings, recovering interstate migration, and a household income base supported by mining services through most of 2025.
The leading indicators to watch in Perth are now: vendor discounting (still at 1.2 per cent versus 3.4 per cent national), auction clearance (low-70s, holding), and most importantly the mining services employment data. The Westpac 1H FY26 results commentary flagged the Pilbara mining-services slowdown as a contributor to its WA arrears. If that pattern spreads from arrears to listings, Perth's capital city values will follow.
Brisbane and Adelaide: the steady middle
Brisbane and Adelaide are the steady middle of the cycle, both still rising at around 1 per cent a month with annual growth in the mid-teens. Listings remain at multi-year lows in both cities, which structurally holds prices up even as buyer demand cools at the margin.
For buyers in Brisbane and Adelaide, the market remains a seller's market on practical terms: short days-on-market, low vendor discounting, auction clearance rates in the high-60s to low-70s. The First Home Guarantee mechanic plus state-level concessions (QLD FHOG on new builds; SA stamp duty exemption) plus the federal Help to Buy shared-equity scheme make both markets accessible to FHBs despite the price levels.
What it changes for borrowers
For Sydney and Melbourne buyers, the cycle now offers the most negotiable window of the past decade. Combined with the federal First Home Guarantee place-cap removal from October 2025 (no annual limit) and the May 6 RBA hold confirmation, the conditions for first home entry in the two largest markets have not been this favourable in five years.
For Sydney and Melbourne existing owners considering refinancing, the soft prices mean a tighter LVR position than 12 months ago and reduced ability to unlock equity. If you bought between mid-2024 and late 2025 in either city, your current valuation may be flat or down despite headline national growth.
For Perth, Brisbane, Adelaide buyers, the market remains tight but the rate environment has stabilised. Run borrowing power at current buffered rates rather than waiting for the cycle to do work; the practical move is borrowing capacity assessment plus a clear list of acceptable properties rather than market timing.
Bottom line
The May 2026 data confirms what April implied. Sydney and Melbourne are in a confirmed correction. Perth is still in the late-cycle melt-up that nobody quite predicted. Brisbane and Adelaide are the steady middle. The national headline numbers will continue to underweight the gap; the practical decision for any borrower is which city the property sits in, not what the combined-capital index does.
