Australian dwelling approvals were characterised by significant monthly volatility through 2025, driven almost entirely by the multi-unit segment. The headline seasonally adjusted series swung from +12.0% in September to -6.4% in October, then surged 15.2% in November — reaching a near four-year high of 18,406 dwellings — before reversing sharply with a 14.9% decline in December to 15,542 units.The pattern reflects the lumpy nature of apartment and higher-density project approvals, which can swing 25-35% in a single month. Private sector house approvals, by contrast, have been comparatively stable, posting modest gains of less than 2% in most recent months and supported by a gently rising trend through the second half of the year.Despite the monthly noise, the broader trajectory through 2025 was constructive. Approximately 195,500 new homes were approved in the year to November, the highest annualised pace since early 2022 and a meaningful improvement on 2024. Multi-unit approvals accounted for the bulk of the recovery, with November's apartment figures reaching their highest monthly level since June 2018. Rate cuts delivered earlier in 2025 provided a tailwind for demand, and government density initiatives have supported the medium-rise pipeline.However, approvals remain well below the roughly 240,000 annual pace required under the National Housing Accord, and converting approvals into completions continues to face headwinds from labour shortages, elevated construction costs, and financing constraints. The trend estimate for total dwellings dipped 0.2% in December after a brief uptick, suggesting the underlying recovery has plateaued rather than accelerated. The January data, with market expectations of a 5.7% monthly rebound, will indicate whether the second half improvement has enduring momentum or remains hostage to apartment-driven volatility.Current account data for Q4 was released at the same time and showed -21.8B vs -16.5B expectedNet exports contribution -0.1% vs -0.3% expected This article was written by Adam Button at investinglive.com.
