Highlights

  • The seasonally adjusted value of non-residential building approvals increased 45.9% to AUD 7.96 billion.
  • Total building approvals by value increased 13.0% to AUD 19.02 billion.
  • The non-residential trend estimate declined 1.1%, indicating that the monthly increase differed from the underlying trend.

Australia’s building approvals recorded a significant increase in value during September 2026, supported by a sharp rebound in non-residential construction approvals. According to the Australian Bureau of Statistics (ABS), the seasonally adjusted value of non-residential building approvals increased 45.9% to AUD 7.96 billion, reversing part of the previous month’s substantial decline. The increase helped lift the total value of building approvals despite weaker residential building values.

Non-Residential Approvals Recover After August Contraction

The ABS reported that non-residential building approvals increased 45.9% during September, following a 45.5% decline in August. This sequence highlights the considerable Volatility that can occur in the value of approved non-residential building projects. Non-residential approvals cover building activity outside the residential category. The value of approvals can therefore fluctuate significantly depending on the timing and scale of individual projects. The September increase indicates that the value of approved non-residential work was substantially higher than in August. However, the supplied ABS figures do not identify which specific building categories or projects accounted for the increase.

Total Building Approvals Rise to AUD 19.02 Billion

The value of total building work approved increased 13.0% to AUD 19.02 billion in September, following a 21.2% decline in August. The September total comprised approximately AUD 11.06 billion in residential building approvals and AUD 7.96 billion in non-residential approvals. While non-residential approvals increased substantially, residential building approvals declined 2.8%. The contrasting movements indicate that the non-residential segment was the principal contributor to the monthly increase in total building approval value.

Trend Figures Show a More Subdued Picture

Despite the strong seasonally adjusted rebound, the ABS trend series indicated softer underlying conditions. The trend value of non-residential building approvals declined 1.1% to AUD 8.94 billion in September, following a 0.7% decline in August. Meanwhile, the trend value of total building approvals decreased 0.5% to AUD 20.27 billion. The difference between the seasonally adjusted and trend series suggests that September’s sharp non-residential increase should be interpreted alongside broader monthly patterns.

Implications for Australia’s Construction Pipeline

Building approvals provide information about authorised future building activity rather than construction work already completed. The increase in non-residential approvals indicates a larger value of work receiving approval during September. However, the figures do not establish when construction will begin, how quickly projects will progress or whether all approved work will ultimately proceed. For construction businesses and related industries, the approval pipeline is one indicator of prospective activity, but it should be assessed alongside subsequent construction and building activity data.

Key Insights

Non-residential building approvals were the main driver of Australia’s September 2026 increase in total building approval value. Nevertheless, weaker trend estimates suggest that the monthly rebound should not be interpreted as conclusive evidence of sustained growth.
