Building enough new homes is not simply a question of approving more developments or setting higher construction targets. The residential construction sector also needs enough qualified workers to turn those plans into completed houses, and the shortage of skilled tradespeople has emerged as one of the industry’s most significant constraints.
Housing Industry Association estimates show the residential construction industry is short around 83,000 skilled workers. Without a substantial expansion of the workforce, the organisation warns that delivering the number of homes required to address the housing shortage will remain extremely difficult.
The challenge reaches across the entire home-building process. New housing requires electricians, carpenters, bricklayers, roofers, tilers and numerous other skilled workers. When those trades are unavailable, construction schedules can stretch out, builders face higher labour costs and projects can become more expensive to complete.
HIA Managing Director Jocelyn Martin says housing targets ultimately depend on having enough appropriately skilled people available to carry out the work. Tradespeople are responsible not only for constructing new homes but also for maintaining existing communities and supporting rebuilding efforts following natural disasters.
The difficulty is that residential construction is not the only sector looking for those workers. Major infrastructure projects are competing for skilled labour at the same time as renewable energy developments, technology projects and the rapidly expanding digital economy.
That competition can make it increasingly difficult for residential builders to secure the workers they need, particularly when major projects are capable of attracting tradespeople with longer contracts or different remuneration structures.
The consequences ultimately reach housing consumers. A shortage of trades can slow the number of homes moving through the construction pipeline. Longer completion times and higher labour expenses can also increase the overall cost of delivering new housing, adding another layer of difficulty to efforts to improve affordability.
The HIA argues that simply moving existing workers between industries will not solve the underlying problem. If a tradesperson leaves residential construction to work on infrastructure or a major technology project, the economy has not created additional skilled capacity. It has merely shifted a limited worker from one project to another.
Expanding the overall workforce is therefore central to the industry’s proposed response.
That means encouraging more people to begin trade careers, but attracting apprentices is only one part of the challenge. Completion rates also matter. The construction sector needs people who start training to remain in the system long enough to become fully qualified and contribute to the long-term workforce.
Businesses that train apprentices also carry a significant responsibility. Supporting employers willing to take on new workers can help ensure apprentices gain the practical experience required to complete their qualifications rather than leaving their trade before becoming fully skilled.
Recent training figures illustrate why the pipeline is important. HIA has previously highlighted declines in the number of construction apprentices in training, increasing concern that today’s workforce shortage could continue unless more workers successfully enter and complete trade careers.
The pressure is especially significant because housing construction is competing against sectors with enormous investment pipelines. Infrastructure programs, renewable energy projects, data centres and other technology-related developments all require workers with skills that overlap with residential building.
In Queensland, for example, HIA has warned that the combination of population growth, energy investment, preparations associated with the 2032 Games and new data centre developments will contribute to sustained competition for construction workers.
That makes workforce planning directly relevant to housing supply. Governments may release land, change planning rules or establish ambitious dwelling targets, but those measures cannot translate into completed housing at the required pace if there are not enough workers available on building sites.
The shortage can also have a cumulative effect. Delayed projects remain in the construction pipeline for longer, while new projects continue to enter it. Builders competing for the same limited trades may face scheduling difficulties, while increased labour costs can affect project feasibility and ultimately the price buyers pay for newly completed homes.
Martin says the long-term answer is to increase the number of skilled people entering and completing trade careers rather than attempting to redistribute the existing workforce.
That requires attention at several stages, from attracting school leavers and career changers into construction to improving training pathways, apprenticeship retention and support for employers providing practical training.
Skilled migration can also help address immediate shortages, but developing a larger domestic workforce remains important if the industry is to maintain construction capacity over the longer term.
The 83,000-worker shortfall therefore represents more than an employment challenge. It is directly connected to the ability of the residential construction industry to increase housing supply, control construction costs and deliver new homes at the pace required.
With housing demand continuing to grow while residential builders compete against infrastructure, renewable energy and technology projects, increasing the skilled trade workforce has become an essential part of addressing the broader housing shortage.
