HIA: New Home Sales Hit Lowest in More Than a Year. Recast 2027 Commencement Books Off the Sales Print.
On Tuesday 15 September 2026 the Housing Industry Association said sales of new homes declined for a fourth consecutive month to their lowest level in more than a year, with Chief Economist Tim Reardon stating that a housing market slowdown is now set for 2027. Nationally, sales fell 10.0 per cent in August and were 19.3 per cent lower in the three months to August than the previous quarter (and 7.7 per cent lower than a year earlier). State declines over that three-month window were led by Victoria (−27.0%), Queensland (−20.2%), New South Wales (−17.5%), South Australia (−10.8%) and Western Australia (−8.2%). Recast 2027 commencement books off today’s sales pipeline — not off current work-in-hand alone.
HIA puts a fourth sales decline — and a 2027 slowdown — on the desk
On Tuesday 15 September 2026, the Housing Industry Association reported that sales of new homes declined for a fourth consecutive month to their lowest level in more than a year.
HIA Chief Economist Tim Reardon said that print “ensuring that a housing market slowdown is now set to occur in 2027.” The HIA New Home Sales report surveys the largest-volume home builders in the five largest states and is published as a leading indicator of future detached home construction.
This article summarises published HIA figures from that 15 September 2026 release. It is not legal, construction or investment advice. Individual jobs turn on contracts, finance and local demand — not a national sales percentage alone.
National print — August and the three months to August
As published by HIA:
- sales of new homes fell nationally by 10.0 per cent in the month of August;
- sales were 19.3 per cent lower in the three months to August than the previous quarter; and
- sales were 7.7 per cent lower than at the same time last year.
Reardon called that a “tangible and significant deterioration” that confirms the recovery in new home building underway at the start of the year has been interrupted. The deterioration was broad based: all five states in the survey recorded a decline over the three months to August.
State split — VIC leads the quarterly fall
In the three months to August 2026, sales declined compared with the previous quarter in all mainland states surveyed:
| State | Change vs previous quarter | | --- | --- | | Victoria | −27.0% | | Queensland | −20.2% | | New South Wales | −17.5% | | South Australia | −10.8% | | Western Australia | −8.2% |
Do not invent a national dwelling count from those percentages — HIA has not published a unit total in this release that converts the % moves into a single national home number.
Taxes, rates and confidence — as HIA framed them
Reardon said the new home market “cannot absorb further interest rate increases on top of the tax increases announced in this year’s Federal Budget.” HIA’s published framing: Budget tax increases weakened market confidence at the same time that three interest rate increases reduced household borrowing capacity and increased mortgage repayments.
HIA also cites falling established home prices and rising construction costs as outcomes that make new home projects harder to finance, plus weaker display-site traffic, fewer enquiries, declining preliminary commitments and rising cancellations. Reardon said it is not possible to isolate precisely how much of the sales deterioration is rates, tax or broader uncertainty — only that their combined effect is clear.
Pipeline lag — 2026 commencements vs 2027 books
HIA’s critical timing line for desks: there was a substantial volume of work in the pipeline when these pressures emerged, so the sales deterioration will not be immediately evident in housing commencements and is unlikely to adversely impact commencements of new homes in 2026.
But “today’s new home sales are tomorrow’s housing commencements.” The decline in sales through the middle of 2026 will mean fewer homes commencing construction in 2027. HIA says that slowdown arrives without a corresponding reduction in Australia’s underlying need for housing — population growth, low unemployment and the existing shortage of homes continue to generate demand for additional supply.
Practical moves for the next four weeks
1. Recast 2027 commencement books off the sales print. Map Q1–Q4 2027 starts against mid-2026 sales, enquiry and cancellation colour — not against work already on site alone.
2. Keep 2026 work-in-hand separate from the forward book. HIA says commencements in 2026 are unlikely to be adversely hit by this sales print. Do not collapse current pipeline and next year’s sales-led commencements into one number.
3. Stress-test state books against the published quarterly declines. Where your exposure is Victoria or Queensland, put the −27.0% and −20.2% three-month prints beside deposit and display-site traffic — cite HIA; do not invent a local unit forecast from the % alone.
4. Keep client and lender language on published figures only. Factual line: HIA New Home Sales (15 Sep 2026) — fourth consecutive monthly decline to lowest sales in more than a year; Aug −10.0%; three months to August −19.3% vs prior quarter and −7.7% vs year earlier; state three-month declines VIC −27.0%, QLD −20.2%, NSW −17.5%, SA −10.8%, WA −8.2%; Reardon — slowdown set for 2027; commencements unlikely adversely impacted in 2026.
5. Do not invent a national home count from the percentages. Cite the published % moves and Reardon’s timing frame unless and until HIA publishes a national unit total you can name.
Bottom line for the desk
On 15 September 2026 HIA put a fourth consecutive new home sales decline — the lowest in more than a year — on the desk, with a broad-based state print and Reardon’s call that a housing market slowdown is now set for 2027. Pipeline lag means 2026 commencements are unlikely to show the hit immediately; 2027 books will. Recast commencement calendars off the sales print — not off current work-in-hand alone.
