SA house build prices jump 3.4% in June quarter, ABS data show

The Australian Bureau of Statistics’ June quarter release, published 31 July, shows South Australian house construction output prices rose 3.4% in the quarter and 8.5% over the year, up from a near-flat 0.3% in the March quarter. For SA builders on fixed-price contracts, the June figure is now the benchmark to price escalation against.

Why it matters

For builders quoting fixed-price contracts in Adelaide right now, the ABS figures confirm the pricing cycle has reaccelerated rather than settled. South Australia’s house construction output price index, which tracks what builders charge for the work, climbed 3.4% in the June quarter after rising just 0.3% in March, ABS data show. Annually, the rise went from 4.1% in the year to March to 8.5% in the year to June.

The input side moved too, but by less. Prices paid for materials and labour on house construction in Adelaide rose 1.9% in the June quarter and 4.4% over the year, up from 1.5% quarterly and 3.7% annually in March, the same ABS releases show. That means the gap between what builders are charging and what they are paying for inputs widened in the June quarter, after running much closer together in March. A builder who locked a fixed price on March-quarter cost assumptions and is now re-pricing variations is working off an output price benchmark that moved more than ten times faster than it did the previous quarter.

The numbers

Set the two releases side by side. March quarter 2026 (reference period, released 1 May): SA house construction output prices up 0.3% quarterly, 4.1% annually; Adelaide input to house construction up 1.5% quarterly, 3.7% annually. June quarter 2026 (released 31 July): SA output prices up 3.4% quarterly, 8.5% annually; Adelaide input prices up 1.9% quarterly, 4.4% annually.

The acceleration is the story. Output price growth in SA was roughly flat through to March, then jumped more than tenfold in quarterly pace by June. Input cost growth also sped up, but only from 1.5% to 1.9%, a much smaller jump. Read together with RLB’s Q3 2026 Crane Index, which counted Adelaide’s residential crane count climbing to 18 of 28 sites, the cost and activity data point the same way: residential building work in Adelaide picked up through the middle of 2026, and pricing power moved with it.

What’s next

The ABS is due to release the September quarter 2026 Producer Price Indexes on 30 October, a week from this article. That release will show whether the June quarter’s jump was a one-off re-rating or the start of a faster run of quarterly rises. Builders and developers pricing new SA contracts should treat the June figure as the current benchmark, not March’s, when setting escalation clauses or rise-and-fall provisions.

For agents and buyers watching what a new house costs to deliver in South Australia, the widening gap between output and input price growth in the June quarter is also worth watching into the next release. If output prices keep rising faster than input costs, builder margins on new contracts should be recovering; if the September quarter shows input costs catching back up, that margin gain will be short-lived.
