Cotality's June Home Value Index landed on Wednesday, and the quarter-end print did not soften the story. The national index fell 0.4 per cent in June, the largest month-on-month decline since December 2022. Sydney fell 1.2 per cent for the month and 3.2 per cent over the June quarter. Melbourne fell 1.0 per cent for the month and 2.6 per cent for the quarter. The combined capitals finished the quarter down 1.3 per cent, the first negative quarter of this cycle.
A month ago we set three tests for this release: whether Sydney's monthly declines would deepen, whether Melbourne would print materially worse, and whether Perth would show any first sign of decelerating. The June data cleared all three with room to spare. Perth added 0.7 per cent, down from an average pace of 2.5 per cent a month through the March quarter. Brisbane managed 0.3 per cent against a 1.9 per cent monthly average earlier in the year. Adelaide printed exactly zero. The two-speed market is still there, but both speeds are now slower.
One detail from the release that most coverage will skip: Cotality has revised recent months lower. The May index was marked down 88 basis points for Perth and 53 for Brisbane in the June update, and the national series is now shown peaking in March. The market has been weaker in real time than the monthly prints suggested, including the ones we reported. Research director Tim Lawless called it a market that is changing rapidly. Treat every current valuation, including your own mental one, as provisional.
The scoreboard at 30 June
- Sydney: down 1.2 per cent in June and 3.2 per cent for the quarter. Annual growth is now just 0.3 per cent, and the median dwelling of $1,265,608 sits 3.7 per cent below the January peak.
- Melbourne: down 1.0 per cent in June and 2.6 per cent for the quarter. Annual growth has gone negative at minus 0.9 per cent; the median dwelling is $808,486, still 4 per cent below the March 2022 record.
- Brisbane: up 0.3 per cent in June and 17.4 per cent for the year. Median $1,118,306, still at its peak.
- Adelaide: flat in June, up 11.6 per cent for the year. Median $945,868.
- Perth: up 0.7 per cent in June and 23.9 per cent for the year, still the national outlier. Median $1,046,551.
- Combined capitals: down 0.6 per cent in June and 1.3 per cent for the quarter, with annual growth fading to 6.1 per cent. Median $1,024,840.
The demand indicators behind those numbers matter more for the September quarter than the index itself. Combined-capitals auction clearance has held below 50 per cent since the last week of May and dropped into the low 40s by late June. Capital city sales over the three months to June are an estimated 16.2 per cent below the same period last year and 14.5 per cent below the five-year average. Advertised stock is almost 11 per cent higher than a year ago, and Cotality is explicit that this is not a wave of new listings; it is unsold stock accumulating because buyers are not clearing it.
How deep is this correction, really
Sydney is 3.7 per cent below its January peak and the monthly declines are getting bigger, not smaller: 0.6 per cent in April, 0.9 in May, 1.2 in June. At the June pace, roughly $15,000 a month is coming off the median Sydney dwelling. Melbourne is about 4 per cent below its late-2025 high, and Melbourne dwellings are now worth less than they were a year ago, the only capital in the June table where annual growth is negative.
For scale, the 2022 correction took Sydney down a little over 12 per cent from peak to trough in under a year. This one is shallower so far, but it is accelerating rather than basing, and the drivers are not going away by spring: the cash rate held at 4.35 per cent in June after 75 basis points of hikes since February, the May Budget's negative gearing and CGT changes are actively pulling investors out of established stock, and consumer sentiment fell again in June. Cotality's own base case is a further drift lower rather than a sharp national correction. We would not argue with that, with one caveat: every recent month has been revised weaker after the fact, not stronger.
If you have been waiting to buy: the honest maths
The uncomfortable truth for anyone sitting on their hands since summer: waiting has been free money in Sydney and Melbourne, but only for buyers who do not need much finance. Sydney prices are down 3.5 per cent year to date. Borrowing capacity for a finance-dependent buyer is down roughly 8 to 10 per cent over the same stretch, because all 75 basis points of hikes flow straight through the 3 per cent APRA serviceability buffer. A buyer whose February pre-approval said $700,000 is closer to $640,000 today. The price fell 3.5 per cent; the budget fell 9. Waiting made the cash buyer richer and the borrower poorer.
The case for buying this winter is leverage, not price. Clearance rates in the low 40s mean vendors are negotiating again: finance clauses are winnable, building-and-pest conditions are back, and an offer 5 per cent under asking is a conversation rather than an insult. First home buyers keep the extra kicker of the First Home Guarantee with no place caps, which converts a falling market into a genuinely cheap entry. The case for waiting longer is momentum: the declines are accelerating, stock is building into spring, and no credible read of the RBA calendar has a cut before November. Both cases are respectable. What is not respectable is waiting for the bottom to announce itself. In 2023, Sydney bottomed in January and rose 11 per cent before the year was out. The people who bought at that bottom did not know it was the bottom; they bought properties that worked at prices that worked.
If you are refinancing: the valuation problem got worse this quarter
Every automated valuation model at every lender ingests this index. A Sydney AVM that priced your property in March is working from a number about 3 per cent higher than today's, and in falling markets the models are deliberately calibrated conservative on top of the raw index move. We published the full playbook on valuation shortfalls in early June; the quarter-end print makes it more relevant, not less.
The arithmetic that kills deals right now: you bought a Sydney house in early 2025 for $1,150,000 with 20 per cent down, and the loan is paid to about $890,000. You assume the place is worth $1,175,000, because that is what it was worth last spring. The AVM, reweighted against six months of index declines, returns $1,095,000. That is an $80,000 gap you never see until the broker calls about an LVR issue, and it moves the refinance from a comfortable 76 per cent LVR to just over 81, which means lenders mortgage insurance or a rate loading that eats the entire saving.
It is still worth running, because the prize is real. RBA data puts the average outstanding variable owner-occupier rate around 6.38 per cent, and that back book lives mostly at CBA, Westpac, NAB and ANZ, all of whom passed the three 2026 hikes through in full within a fortnight. Meanwhile Macquarie's Basic product, ING's Mortgage Simplifier and Athena are writing new sub-80 LVR owner-occupier loans between roughly 5.74 and 5.99 per cent. On that $890,000 loan, closing a 50 basis point gap is about $4,450 a year. The sequencing is the whole game: get valuation estimates run across several lenders upfront, before any application touches your credit file, and route the deal to the lender whose number clears 80. If nothing clears, take the retention reprice at your own bank, the 15-minute call we published the script for last month, and rebuild equity for a quarter or two.
Perth, Brisbane, Adelaide: the other speed is slowing too
Nobody in the west needs to panic over one soft month. Perth is still up 23.9 per cent for the year and sits at its peak. But the deceleration is sharp: an average of 2.5 per cent a month through the March quarter, a printed 1.5 per cent in May that the June update then revised 88 basis points lower, and 0.7 per cent in June. If you are buying in Perth or Brisbane, stop underwriting last year's growth rate into the decision. Buy on what the repayments look like at 4.35 per cent plus the buffer, not on the assumption the market bails you out. And keep one eye on mining services employment, which the May bank results flagged as the soft spot in WA arrears; if that spreads from arrears to listings, Perth's run ends the ordinary way.
What you should actually do
- Buying in Sydney or Melbourne: get the pre-approval re-run at current rates before you bid on anything, then use the market's weakness at the table. Finance clause in, building and pest in, and open below asking on anything that has sat for 30 days. Stock is up 11 per cent year on year; the vendor needs you more than the agent lets on.
- Refinancing in Sydney or Melbourne: valuations first. Have a broker run AVM estimates across three or four lenders before anything is lodged. If the best number still lands above 80 per cent LVR, make the retention call to your own bank and revisit in six months.
- Buying in Perth, Brisbane or Adelaide: the deceleration is real, so drop the fear of missing out. Negotiate off the June print, not the January one, and run the borrowing power maths at today's buffered assessment rates.
- Selling in Sydney or Melbourne: price to August's market, not February's. In a falling market the first serious offer is frequently the best you will see, and at the current pace every extra month on market costs a Sydney vendor around 1 per cent of value.
- Everyone: two dates matter this month. APRA's serviceability buffer consultation closes on 18 July, and the Q2 CPI print on 30 July sets up the August RBA meeting. Between them, they decide whether borrowing power loosens or tightens into spring.
Bottom line
The quarter-end read is simple. The Sydney and Melbourne correction is confirmed, deepening and accelerating. The boom in the mid-sized capitals is decelerating toward stall speed. And the index that every valuation model runs on is being revised down after the fact, which means the market you transact in is a little weaker than the one in the headlines. Plan against the trend, not the print.
