The SEQ Development Brief

Headline inflation eased in May. The core measure the RBA watches did not.

The Australian Bureau of Statistics monthly Consumer Price Index indicator rose 4.0% in the year to May 2026, down from 4.2% in April (ABS, released 24 June). On its own that looks like the disinflation the market wanted. The detail underneath runs the other way. Trimmed mean inflation, the core measure that strips the largest price moves in each direction and the one the Reserve Bank weights most heavily, rose to 3.6% from 3.4% in April. Housing was the largest contributor to the annual figure at 6.5%, ahead of food and transport at 3.3% each. Headline came down; the underlying trend firmed.

That split lands directly on the August rate decision. The Reserve Bank held the cash rate at 4.35% on 17 June, its first pause after three hikes earlier in the year, and kept an explicit line that it would lift again if required. The major banks were already divided heading into August, three reading a cut and Westpac a further rise. A core print moving up rather than down hands the hawkish case its evidence. A headline print moving down gives the doves theirs. The one number did not settle the argument; it sharpened both sides of it.

For operators the read is on settlement risk, not on a turn. Feasibilities and presale models written against a clean easing path now carry a live scenario where 4.35% holds through the second half or moves higher. The buyers carrying the most sensitivity are the dual-income, high-DTI households that have set the SEQ presale ceiling all year, and they are the first to feel a core print that keeps the cash rate where it is. Hold both rate paths open in anything signed before the August meeting. (Sources: ABS Monthly Consumer Price Index Indicator, May 2026, released 24 June 2026; RBA cash rate decision, 17 June 2026.)

The inflation print above headlines the data week; this section carries the rest, and the standout is the auction market. Cotality’s preliminary combined-capitals clearance rate fell to 47.4% for the weekend ending 21 June, the first sub-50% result since April 2020, down from 54.0% the week before and well below the 65.3% of a year ago. Brisbane ran softer than the national line at 33.3%, its fifth straight week below 50%. Auction volumes are thin in Brisbane, a market that sells mostly by private treaty, so the local figure swings on small samples and reads as a sentiment signal more than a price one. The national series does not have that excuse. A combined-capitals clearance rate at a five-year low is buyers stepping back, and it sits awkwardly next to a core inflation figure that firmed.

Supply stayed weak. The most recent ABS Building Approvals print is April 2026 (released 10 June): national total dwellings approved fell 3.4% on a seasonally adjusted basis to 16,710, after March’s 10.5% fall, while Queensland edged up 0.3% to 3,946. The May print releases 1 July, the day after this issue. Cotality’s May Home Value Index, still the most recent released values read, held national values flat at 0.0% for the month with Brisbane at +0.9%; the June index is also due about 1 July. On rents, SQM Research’s May vacancy print (released 15 June) left the national rate at 1.2% and Brisbane at 0.9%, with Brisbane combined rents up 9.1% over the year. Soft approvals and sub-1% vacancy keep the supply gap open while demand cools at the top.

Brisbane

Keylin lodged a development application on 25 May for Lotus on Water Street, a 15-storey mixed-use building at 290 Water Street and 137 to 141 Warry Street, on the Fortitude Valley edge of Spring Hill. The proposal keeps and restores the heritage-listed Brunswick Home Furnishers Showroom along Water Street and sets a tower behind it, with 132 apartments across one, two and three bedrooms, of which 56 are configured as short-term accommodation able to switch to standard dwelling use, plus about 518 square metres of ground-floor retail on a 2,869 square metre amalgamated site. It is the kind of heritage-retention infill that keeps moving through the inner-city pipeline regardless of where auction clearance sits, because it sells off the plan to owner-occupiers and investors rather than under the hammer.

The feasibility model is where AI earns its keep this cycle

When demand cools and the rate path stays open, the margin for error on a feasibility narrows, and that is exactly where the current generation of property AI is most useful to a small operator. The Property Council of Australia’s ANZ PropTech Report 2026, a survey of 236 senior real estate professionals, found adoption accelerating but confidence lagging, and made one observation that matters more than any adoption percentage: the technology is being used to simplify work far more than to reshape decisions (Property Council of Australia, ANZ PropTech Report 2026). That gap is the opportunity. The operators getting value are not handing judgement to a model. They are compressing the slow, repeatable parts of the pipeline so they can run more scenarios on the parts that need a person.

Early-stage feasibility is the clearest case. Platforms such as Archistar now read a site’s planning controls and generate compliant building envelopes with area schedules and indicative yields in hours, against the weeks a manual test fit takes (Archistar). For a small developer weighing a corner block against a duplex code, that turns a single go or no-go test into ten, and the marginal sites that fail under one configuration and clear under another are precisely the ones a thin market leaves on the table.

The tie-back to this week is direct. The reforms widening accepted and small-lot development across Brisbane and the Sunshine Coast multiply the number of compliant configurations a given site allows, more permutations than a manual feasibility can practically test. A cooling auction market raises the cost of getting the configuration wrong. Faster scenario testing is not a productivity nicety in that setting; it is how an operator finds the yield that still works once the easy growth has gone out of the market. The judgement the model cannot see, build-cost nuance, code interpretation, what a particular street will actually pay, stays with the operator, and it is worth more, not less, when the tools commoditise everything around it.
