Australia’s latest housing data is sending two seemingly conflicting messages. Dwelling approvals, a leading indicator of future construction activity, have remained volatile from month to month but continue to trend higher, particularly in the multi-unit sector. At the same time, dwelling commencements, which measure construction actually starting on-site, recorded their sharpest quarterly decline in several years.
Sitting between these two indicators is structural timber demand. Softwood structural timber sales have continued to strengthen through 2026, suggesting the industry is responding to the underlying recovery signalled by approvals months earlier, rather than the short-term volatility evident in commencement data.
The Latest ABS Release: Commencements Fall Sharply
The ABS Building Activity, Australia release for the March 2026 quarter showed total dwelling commencements falling 11.2% to 48,012 dwellings in seasonally adjusted terms. The weakness was concentrated in the higher-density segment. Private sector other residential commencements, which include townhouses, units and apartments, fell 20.7% to 19,116 dwellings after rising 26.0% in the December 2025 quarter. Private sector house commencements also declined, although more modestly, falling 3.5% to 27,658 dwellings.

The result represents a sharp reversal from the previous quarter. In the December 2025 quarter, total commencements had increased 8.0% to 53,567 dwellings, driven largely by a 23.4% increase in other residential commencements to 23,849 dwellings.
The swing from a strong December 2025 quarter to a weak March 2026 quarter highlights the volatile nature of housing commencements, particularly in the multi-unit sector. Large apartment projects can significantly influence quarterly outcomes, making commencements far more erratic than detached housing activity.
Building Approvals: The Leading Indicator of Future Supply
While commencements weakened, approvals data tells a somewhat different story. Across the first five months of 2026, multi-unit approvals experienced substantial month-to-month swings. Private sector dwellings excluding houses fell 24.5% in January after declining 30.7% in December, rebounded in February, dropped 26.0% in March, rose 4.0% in April, and then declined a further 10.4% in May. House approvals have been considerably more resilient. Private sector house approvals increased 2.8% in May 2026 to 10,537 dwellings, the highest monthly result since September 2021. Importantly, May marked the fourth consecutive month with approvals above 10,000 dwellings. Although total approvals declined 1.1% for the month, they remained 5.3% above their level a year earlier.
The divergence between approvals and commencements is a common feature of housing cycles. Approvals represent projects that have received planning consent, while commencements capture projects that have physically started construction. Between those two stages, developments may face financing constraints, feasibility challenges, labour shortages, or delays in securing construction contracts.
As a result, approvals often provide an early indication of future activity, while commencements reflect decisions made several months earlier. The March 2026 quarter illustrates this dynamic clearly: approvals for detached houses remained near five-year highs, yet total commencements fell sharply over the same period.
FWPA Forecasts and Structural Timber Demand
FWPA’s latest dwelling forecasts suggest that commencements may moderate in the short term before recovering as approved projects progressively move through the construction pipeline and into on-site activity.
This outlook is reflected in recent structural timber sales data. Throughout 2026, structural softwood sales increased by an average of approximately 2.4% per month, signalling a gradual strengthening in residential construction activity. While dwelling commencements can be volatile from quarter to quarter, particularly in the multi-unit segment, the steady growth in structural timber demand suggests builders are continuing to work through the growing pipeline of approved housing projects, supporting a broader recovery in the residential construction sector.

Unlike commencements, which can be heavily influenced by the timing of large projects, timber demand often provides a smoother signal of underlying building activity. Structural timber is typically purchased once projects begin moving through the construction pipeline, meaning sales tend to reflect broader housing activity rather than short-term fluctuations in approvals or commencements.
What the Three Indicators Tell Us Together
Viewed individually, approvals, commencements, and structural timber sales can paint very different pictures of the housing market. Taken together, however, they provide a more complete understanding of where the residential construction cycle is heading.
- Approvals remain the earliest indicator of future housing supply. Despite considerable monthly volatility, particularly in the multi-unit sector, the underlying trend for detached houses has continued to improve.
- Commencements measure construction activity actually starting on the ground. Their 11.2% quarterly decline highlights the lag between projects being approved and projects commencing construction, particularly for higher-density developments where financing and feasibility remain critical considerations.
- Structural timber sales reflect activity further along the construction pipeline. The steady growth in sales throughout 2026 suggests builders are responding to the broader recovery signalled by approvals, even as commencements continue to fluctuate from quarter to quarter.
The Takeaway
The apparent contradiction between rising approvals and falling commencements is not unusual. Housing construction operates with long lead times, meaning different indicators often tell different parts of the same story. The latest data suggests approvals are signalling a gradual recovery in residential construction, while commencements remain affected by project timing and short-term volatility, particularly in the apartment sector.
For the timber industry, that may be the most important signal of all. While commencement data can fluctuate sharply from quarter to quarter, the steady rise in structural timber demand suggests the broader housing recovery remains intact, albeit progressing more gradually than headline approval figures might imply.
