New home sales fall 10% as the 2027 construction pipeline weakens

Australia’s new-home recovery has stalled, with sales falling sharply as higher borrowing costs, expensive construction and weak buyer confidence combine to squeeze the market.

Housing Industry Association data reported by SBS News on Wednesday showed sales of new homes fell 10 per cent nationally in August. Sales were 19.3 per cent lower over the three months to August than in the previous three-month period.

It was the fourth consecutive monthly fall, taking sales to their lowest level in more than a year.

The decline was broad rather than confined to one weak market. Over the quarter, Victoria recorded the largest fall at 27 per cent, followed by Queensland at 20.2 per cent, New South Wales at 17.5 per cent, South Australia at 10.8 per cent and Western Australia at 8.2 per cent.

The HIA survey covers large-volume builders across the five mainland states. It is closely watched because purchases of house-and-land packages and other new detached homes usually occur well before construction begins.

Why sales are falling

New homes are competing against established properties at a time when household borrowing capacity is under pressure.

Independent property economist Cameron Kusher told SBS that buyers were questioning whether a new home was worth its price premium when an older property could be purchased for less. Higher interest rates can also leave prospective purchasers unable to borrow enough for the home and land package they had planned.

Cotality research director Tim Lawless said the wider housing market had slowed, but new homes appeared to have been affected more severely. Cotality estimated total home sales over winter were about 15 per cent lower than a year earlier and 11 per cent below the five-year average.

Builders are also dealing with elevated material, labour and development costs. These expenses make it difficult to cut prices without affecting project viability, even when buyers have less money available.

The result is an affordability stand-off: builders need prices that cover the cost of delivering a home, while purchasers need prices that work within tighter loan limits.

The delayed supply effect

The immediate effect is fewer contracts for builders. The more important consequence may not become visible until next year.

HIA chief economist Tim Reardon said the fall in sales through the middle of 2026 would translate into fewer housing commencements in 2027. Builders had reported reduced traffic through display villages, fewer enquiries and preliminary commitments, and more cancellations.

That creates a difficult cycle for housing supply. Australia still needs additional homes, but the projects most capable of adding to detached housing stock cannot proceed unless buyers can afford them and builders can deliver them profitably.

A temporary fall in demand may ease pressure on trades and materials. However, a prolonged sales slump would leave fewer homes entering the pipeline, potentially tightening supply again when borrowing conditions or confidence improve.

What buyers should check

Anyone comparing a new build with an established home should consider the complete cost rather than the advertised starting price.

• Include land, site works, landscaping, window coverings and upgrades in the new-home budget.
• Check whether the building contract allows price variations and how long finance approval remains valid.
• Compare likely completion dates with the cost of rent or another mortgage during construction.
• Confirm what happens to the deposit if finance, registration or construction is delayed.

What it means for you

• Buyers may gain negotiating power with builders, but should examine inclusions and contract risks carefully.
• Fewer sales now are likely to mean fewer detached homes starting construction in 2027.
• Established homes may attract more demand where they offer a lower total cost and immediate occupancy.
• Sellers of vacant land or near-new homes could face softer demand while borrowing conditions remain tight.
