Australia is experiencing a notable upswing in residential construction, with new data revealing strong growth in housing activity alongside a substantial increase in commercial building projects, particularly datacentres. The latest figures, covering the year to June 2026, show residential building volume rising by 8.7%, marking the strongest growth since 2016. Overall building activity climbed even higher, up 10% year-on-year, the most significant increase since the global financial crisis stimulus period.
Private sector house commencements reached 31,707 dwellings, an 11.6% rise and the highest level recorded since 1994, excluding the temporary surge driven by the COVID-19 homebuilder stimulus and a GST-related spike in 2000. Analysts suggest this reflects a shift by investors toward new housing projects, encouraged by the continued availability of a 50% capital gains tax discount on new property development. However, economists note that data from subsequent quarters will be necessary to determine if this growth is sustained or a short-term response to recent policy changes, including the federal budget.
While private housing construction shows encouraging signs, public sector housing remains marginal and has not significantly contributed to supply for over three decades. According to a recent report by the Senate’s select committee on intergenerational housing inequality, chaired by Greens Senator Barbara Pocock, Australia faces a prolonged housing crisis. The committee emphasized consensus across political lines that substantial action is needed to address affordability and supply issues, with a particular focus on increasing affordable and social housing through sustained government investment.
The report highlights that public and community housing represented only 2.3% of new residential building in the year to June, a stark contrast to the average of 13% between 1955 and 1985. Senator Pocock has called for a national target to raise this share to at least 10% within the next decade, a move that would represent a significant policy shift. The committee also noted concerns about rising rents, recommending a cap on annual rent increases at the lower of 2% or the inflation rate. Debates continue over the causes of rental price growth, with some political parties attributing it to tax changes and migration policies, though economic analysis points to interest rates as the primary driver.
Beyond housing, the data reveals that the rapid expansion of datacentre construction is impacting the availability of building resources. Classified under "commercial building not elsewhere classified," datacentres accounted for 20% of non-residential building commencements in the past year, a substantial jump from their usual 1% share. This surge contributed nearly three-quarters of the increase in non-residential building activity during this period.
The scale of investment in datacentres is significant, with expenditures exceeding those for factories by more than 17 times in the latest year. While datacentres are critical infrastructure for technology and data services, their construction is labor- and resource-intensive but supports relatively few ongoing jobs compared to factories or housing. This dynamic raises questions about the opportunity cost of diverting construction capacity and investment away from more labor-intensive and socially beneficial projects such as housing and manufacturing facilities.
As Australia navigates a complex economic and political landscape around housing supply and infrastructure investment, observers caution that the current datacentre boom could limit progress in alleviating housing shortages. The challenge remains to balance multiple national priorities while ensuring that construction efforts deliver lasting benefits for the broader population.
