The Australian building sector completed a total of 42,615 new private dwellings in the March 2025 quarter, according to seasonally adjusted figures from the Australian Bureau of Statistics (ABS).
This data provides a detailed breakdown of completions across housing types, confirming the rate of supply for the first quarter of the calendar year.
Breakdown of dwelling completions
The total completions figure for the quarter was composed of two primary categories:
- New Private Sector Houses: 27,858 dwellings completed.
- New Private Sector Other Residential: 14,757 dwellings completed.
The private house segment, comprising detached and stand-alone homes, was the dominant contributor to housing supply, representing 65.4 per cent of the total dwellings completed during the period.
Quarterly completion rate analysis
Total dwelling unit completions in Australia fell 4.0% in the March 2025 quarter compared to the December 2024 quarter, according to the ABS.
This decline was driven by:
- Private New Other Residential: A 9.3% decrease in completions (which includes apartments and other multi-unit dwellings).
- Private New Houses: A 1.3% decrease in completions.
| Dwelling Type | Dec 2024 Qtr (Calculated) | Mar 2025 Qtr (Reported) | Change (%) |
| Total Dwelling Units | 45,330 | 43,517 | -4.0% |
| Private New Houses | 28,027 | 27,663 | -1.3% |
| Private New Other Residential | 16,748 | 15,190 | -9.3% |
Forward pipeline activity
While completions measure finished housing stock from previous periods of construction, new activity provides an indication of future supply. The data for dwelling commencements in the March 2025 quarter showed a rise, which is critical for bolstering the housing pipeline.
New private sector house commencements increased by 6.3 per cent over the quarter, and new private sector other residential commencements rose by 21.8 per cent. These increases in building starts suggest potential for higher completion volumes beyond the March 2025 quarter as projects progress to final delivery.
The industry monitors these figures closely as it works to address the national housing supply deficit.
