Master Builders Cuts Five-Year Home Starts Forecast to Under 920,000 — 62,000 Fewer Than March. Recast Your Book Toward Steadier Segments.
On Wednesday 1 October 2026 Master Builders Australia released forecasts downgrading all three segments of building and construction since March. Over the five years to 2030-31 it now projects fewer than 920,000 new home starts (an 8.4 per cent write-down and 62,000 fewer starts than March), $331 billion of non-residential work and $688 billion of engineering construction, with a 262,000-home deficit over the National Housing Accord. House approvals are still at a five-year high on HIA’s read of the August ABS data — plan the 2027 book on forward signals, not last month’s approvals.
Master Builders downgrades every segment since March
On Wednesday 1 October 2026, Master Builders Australia released its latest industry forecasts and said prospects for building and construction have deteriorated, with projections for all three segments — residential, non-residential and engineering — downgraded since the previous forecasts were published in March.
This article summarises the published Master Builders media release of 1 October 2026, with context from the HIA commentary on ABS building approvals of 30 September 2026. The full forecast reports are paid products; we have not reproduced any figure that is not in the public release. This is not legal, construction or investment advice.
The five-year numbers to 2030-31
Over the five years to 2030-31, Master Builders projects that:
| Segment | Published projection | | --- | --- | | New homes commencing | Less than 920,000 — an 8.4 per cent write-down on March | | Non-residential building work | $331 billion carried out (+2.9 per cent on the past five years) | | Engineering construction work | $688 billion completed |
Master Builders said its forecast horizon now holds 62,000 fewer new home building starts than it expected in March, and that a 262,000-home building deficit is now anticipated to accumulate over the full term of the National Housing Accord.
Why the downgrade — as Master Builders framed it
Chief Economist Shane Garrett attributed the downgrade to policy decisions in the May 2026 Federal Budget, continued interest rate increases and an unfavourable geopolitical environment, adding that little progress has been made on the industry's supply-side capacity.
> “New home builders are in the eye of a perfect storm. It's much harder to sell new homes when established dwelling prices are on the way down.”
Garrett said builders have no room to reduce costs because of tradie shortages and escalating prices of key building materials, and warned that weak productivity raises the risk that several more rate hikes will be needed to quell inflation — in which case prospects could worsen further.
CEO Denita Wawn said new home building struggles to expand because of tradie shortages, reduced investment, declining productivity and regulation totalling up to $320,000 per new house. Master Builders is calling for the Budget tax changes to be reversed — particularly for the higher-density sector — and for fixes to the National Construction Code, skilled migration settings and domestic training pathways.
Where the work holds up
The release is not uniformly gloomy. Garrett said non-residential demand is partially insulated by a substantial portfolio of public-sector funded projects, and named data centres as one of the most interesting features of that market.
In civil and engineering construction, resources and utilities projects are expected to be the strongest performers. By contrast, transport and recreation-related construction are looking at significantly less work than in recent years.
Approvals are still running on last year's momentum
The forecast landed a day after ABS approvals for August 2026. HIA Senior Economist Tom Devitt said house approvals rose to 11,040 in August — the highest level in five years and up 3.3 per cent on July — with the three months to August 14.6 per cent higher than a year earlier.
Devitt cautioned that there are long lags in home building and it is still too soon to see this year's pressures in approvals. HIA said the impact on approvals and on-the-ground commencements is unlikely to show until next year and beyond. In other words: a strong approvals print and a downgraded starts forecast can both be true at once.
Practical moves for the next quarter
1. Separate this year's pipeline from the forward book. Work already sold and approved can carry activity for the rest of 2026, as HIA notes. Don't let a five-year-high approvals print set your 2027 commencement assumptions.
2. Look at where the published outlook is firmer. If your crews and plant can work outside detached housing, Master Builders points to public-funded non-residential work, data centres, and resources and utilities civil projects as the steadier segments. Test your capability honestly before chasing them.
3. Re-price carry costs, not just build costs. Master Builders and HIA both point to rate rises lifting the cost of carrying work. Review finance, progress-claim timing and variation clauses on jobs that start later than planned.
4. Keep client and lender language on published figures. Factual line: Master Builders forecasts (1 Oct 2026) — fewer than 920,000 home starts over the five years to 2030-31, an 8.4% write-down on March and 62,000 fewer starts; 262,000-home Accord deficit; $331bn non-residential; $688bn engineering.
5. Don't invent state or trade splits. State-level detail sits in the paid forecast reports. Unless you have bought them, quote the national release only.
Bottom line for the desk
Master Builders has cut its five-year home starts outlook to under 920,000, while non-residential and civil work look steadier on its numbers. Approvals are still strong because of momentum built before this year's pressures, so plan the 2027 book on the forward signals — not on last month's approvals alone.
