Australia’s housing crisis has been described as a challenge of ‘war-time’ proportions, and nowhere is the urgency more acute than in social and affordable housing.

Waiting lists are growing, homelessness is rising among both unemployed and working Australians, and the wellbeing impacts of insecure housing are becoming increasingly visible.

At the same time, Australia’s construction sector continues to struggle with chronic productivity challenges. The search for solutions to both crises is converging, and modern methods of construction (MMC) offer an unprecedented opportunity to deliver more housing while transforming the efficiency of the industry itself.

As of mid-2024, there were around 452,000 social housing dwellings nationally, housing just over 830,000 people. That stock has barely grown for more than a decade while population has surged, meaning the share of households in social housing has fallen to about 4.1%, down from 4.7% a decade ago¹.

The Federal Government has acknowledged the scale of the challenge. Through the Housing Australia Future Fund (HAFF) and the National Housing Accord, Canberra expects to support the delivery of 20,000 new social and 20,000 new affordable homes over five years². The 2025–26 Budget also lifted Housing Australia’s liability cap by $16 billion, expanding its capacity to finance new projects³. Meanwhile, states and territories are making their own commitments: Tasmania has pledged 10,000 homes by 2032⁴, and the ACT has created a ‘priority projects’ pathway to fast-track public housing and health builds⁵ with 30,000 homes planned by 2030.

Alongside funding, the Budget also earmarked $54 million to accelerate prefabricated and modular construction, including $49.3m in state/territory programs and $4.7m for the Australian Building Codes Board to develop a voluntary national certification scheme for off-site construction, forecast to commence in 2028⁶.

Modern Methods of Construction (MMC): taking baby steps

Much of the national conversation around Modern Methods of Construction (MMC) has focused on volumetric modular housing, where homes craned onto site with kitchens and bathrooms already installed. While this technology has promise, it is unrealistic to think we can jump from traditional on-site hammer-and-nail construction straight to fully modularised housing at scale.

Instead, the transition to MMC should be incremental. A sensible first step is precast concrete, one of the most established off-site methods⁷.

Precast elements can be designed as a kit of parts, with a potential for multiple configurations of standardised wall and floor panels with pre-formed openings. With a handful of core components, providers could deliver countless variations, from single dwellings to duplexes, all with factory-applied finishes that reduce on-site work. This kind of standardisation offers speed, flexibility, and cost control.

In medium- and high-density housing, precast is already the logical choice and commonly used. In this sector, the advantages are even clearer: fast and more cost-effective construction, safer (less cluttered) construction sites, less waste, unsurpassed durability and the potential for thermally efficient dwellings.

 

Case studies: what precast can deliver

 

  • ACT Trial: A recent pilot delivered a four-bedroom public housing home in just 11 weeks, with precast wall panels stood in two days, requiring no external cladding or framing⁸.
  • Tasmania: The state has explored a dedicated precast panel plant capable of producing up to 1,700 housing panels annually, boosting its ability to meet its 10,000-home target⁹.
  • Trinity Hill, Hobart: This youth accommodation project demonstrated how precast allows wall panels to be manufactured while site works progress, then speedily installed… cutting time and disruption¹⁰.
  • Aboriginal Elders Housing, WA: In Woodbridge, Noongar Mia Mia is partnering with NXT TEC to deliver 11 culturally appropriate homes using precast technology. This is proof the method can be rapid and culturally responsive¹¹.
  • Aboriginal Housing Office, NSW: Just handed over in late August, a 5 bedroom precast home in Queanbeyan took 13 weeks to build.

These examples show precast is not theoretical. It is already being applied to public housing with tangible success.

 

Why precast stands apart

Unlike some newer MMC systems, precast integrates smoothly with conventional construction and design processes.

Australia also has a mature precast industry, with factories, standards, and workforce already in place… reducing the risks of scaling up. Add to this the development of new micro-credentials for precast factory and allied industry workers – funded in Queensland and accessible nationally – and the sector is actively pursuing growth in a workforce that has the specialised skills that are needed to manufacture precast safely and efficiently¹².

Global evidence shows that when properly designed for manufacture and assembly, off-site methods can deliver projects 20 to 50% faster and up to 20% cheaper than traditional builds¹³. Precast is well-placed to achieve those gains in social housing because it combines off-site efficiency with local industry capacity.

A call to broaden the MMC conversation

Meeting Australia’s social housing targets will take more than funding. It will take smarter and faster building methods. Modular will play its part, but we don’t need to leap there in one bound. We can take baby steps.

Precast is that step: a proven, flexible, factory-finished method that can be standardised, scaled, and adapted for both detached homes and multi-unit developments. By embracing precast, governments, housing providers, and industry can deliver quality homes more quickly, safely, and sustainably.

It is remarkable that precast is not being more widely adopted in medium and high density social housing, given its proven durability, fire resistance, and thermal efficiency. The opportunity is right under our noses: a construction method that can not only meet urgent housing demand but also lift the productivity of the sector in ways that few other approaches can rival.

In the race to meet Australia’s housing targets, sometimes the oldest form of MMC is exactly the kind of reliable, practical solution we need.
