What BuildFair contributes to Australia's housing crisis

Australia's residential construction industry has produced 5,000 to 7,000 insolvencies in the two years to early 2025, depending on which ASIC dataset you use and how you define the construction sector. The peak year was 2024. The pattern in 2025 and into 2026 is high but down from peak. By every measure, the residential side of construction has been under more financial pressure than at any point since the 1990s.

Each insolvency where a builder was mid-project on residential builds creates the same set of consequences. The build pauses. The owner becomes a creditor in the insolvency. Subcontractors who were owed money for work already done become creditors too. The site sits, often for months, while administrators and liquidators work through the company. Some builds are picked up by other builders and continue under new contracts; many are abandoned. The owner faces a long, expensive resolution process under the relevant state's owner protection scheme, which typically pays a fraction of the contract value as detailed in our builder insolvency pillar.

The aggregate effect on housing supply is direct. Half-finished houses don't add to housing stock. The chilling effect compounds: subcontractors burned by an insolvent builder become more cautious about taking on residential work in the future, sometimes leaving the residential sector entirely for commercial or government contracts where payment is more reliable. Suppliers tighten credit terms, which makes it harder for the next wave of builders to operate. Owners considering whether to commission a new build factor in the insolvency risk, which has visibly reduced new home commencements over the period.

The construction payment system was a contributor to the surge. Not the only contributor. Materials cost inflation in 2022 and 2023 hit fixed-price contracts hard. Interest rate increases compressed buyer demand. Labour shortages constrained capacity and drove costs. But sitting underneath all of those cyclical pressures was a payment system that put builders in a structurally exposed position even in good times. When the cyclical pressures arrived, the structural exposure broke.

The next two sections describe the two specific structural problems BuildFair addresses.

The first structural problem is well-understood inside the industry and barely understood outside it. Australian residential builders, under the standard payment schedule explained in our progress payments pillar, receive owner funds in stages tied to physical progress. A typical residential build might have five or six progress payments spread across six to twelve months. Between progress payments, the builder is paying suppliers, subcontractors, wages, and overheads out of cash on hand.

The gap between when the builder pays others and when the builder receives the next progress payment is the timing gap. Suppliers want payment in 30 days. Subcontractors want payment in 14 days. Overheads (vehicles, fuel, site costs, the builder's own salary) have to be paid weekly. The next progress payment from the owner or the bank might be six weeks away, sometimes longer if a stage is disputed or a bank inspection is delayed.

In good years with healthy reserves, builders absorb this gap. The reserves are the float that bridges the timing mismatch. In bad years, or for builders without significant reserves, the gap is closed by paying suppliers late, paying subcontractors late, drawing on overdrafts and credit cards, or skipping the builder's own pay. Each of these is a survival tactic that works once or twice and stops working when it accumulates.

When materials inflation and rate rises hit in 2022, many builders entered the period with fixed-price contracts they had signed at lower cost assumptions and reserves that had been thin to begin with. The timing gap that had been a manageable inconvenience in 2019 became unmanageable. Builders who would have been operationally fine in steady conditions found themselves unable to keep paying suppliers and subcontractors while they waited for progress payments. The system had been working at the limit of its capacity. The cyclical shock pushed it past the limit.

BuildFair removes the timing gap as a structural feature.

When a project goes onto BuildFair, the owner's funds for the project are held in regulated escrow. The schedule of releases is agreed at contract signing. Stage releases happen on verified progress, the same as in the standard system. But within each stage, BuildFair also draws a weekly amount for the builder's overheads on that project. The amount is set at contract signing based on the builder's expected weekly run-rate for that build. Each week, the agreed amount releases from the project's escrow account to the builder.

The mechanical effect: the builder receives steady weekly cashflow for the duration of the build, drawn from project funds that the owner has already paid in. The builder doesn't have to bridge the gap between stage payments out of personal reserves or credit. The cashflow timing problem that pushed otherwise solvent builders into insolvency in 2022-2024 is structurally addressed within each project running on the platform.

This doesn't fix every cause of builder insolvency. A builder running negative on a job because materials cost more than the fixed-price contract assumed is still in trouble. A builder operationally bad at running multiple projects simultaneously is still going to fail. A builder who has taken on more work than their team can deliver is still going to miss completion dates. But the specific failure mode of "operationally fine builder driven into insolvency by cashflow timing" is removed from the equation.

The second structural problem is more important than the first and less commonly discussed. Australian residential builders typically run multiple projects simultaneously. A small builder might have two or three jobs at different stages. A mid-tier builder might have ten or twenty. The largest residential builders had hundreds of jobs in progress at any time. When a builder receives a progress payment from Job 1, those funds land in the builder's general operating account. From that account, the builder pays whatever is most urgent across all of their jobs.

This means a progress payment from Job 1 can pay subcontractors who worked on Job 2. A deposit from Job 5 can pay supplier debts from Job 3. The builder's general operating account is one big pool. As long as the pool is replenishing fast enough by progress payments coming in, the system works. As soon as one progress payment slips, the builder reaches into the pool and pays the most urgent bill from whatever's there, regardless of which job the funds technically came from.

This pattern is the cross-project cashflow subsidy. Each job is partially funding the others. Most of the time it's invisible because the pool stays full. When the pool runs dry on one job, the builder takes on a new job partly to refill the pool. When that new job's progress payment runs late, the builder takes on another job. The pyramid grows. The builder isn't doing anything illegal or even particularly unusual; they're managing cashflow the way the system has always allowed.

The pyramid breaks when any progress payment in the chain runs significantly late, or when the builder hits a hard wall (a major dispute, a supplier withdrawing credit, a bank tightening, a tax bill). When the pyramid breaks, multiple jobs collapse simultaneously, because each was partly dependent on the others. The 1,700 stranded Porter Davis builds were not 1,700 separate failures. They were one structural failure that took down 1,700 jobs because each job had been partly funding the others.

BuildFair structurally prevents the pyramid from forming.

Each project on BuildFair has its own escrow account. The funds for each project are ringfenced and can only be released for that project's work and that project's overheads. A progress payment from Owner A's project can only release funds for work on Owner A's project. Owner B's project cannot draw on Owner A's funds, regardless of how urgent Owner B's situation is. The builder's overhead draws are project-specific. The cross-project subsidy that built the pyramid in the first place is mechanically impossible.

The implication is that builders running on BuildFair cannot use the cashflow from one job to plug holes in another. Some builders see this as a constraint. It is a constraint, in the same way that lawyer trust accounts are a constraint on solicitors. The constraint is the protection. A builder who can't subsidise Job 2 from Job 1's funds is also a builder who can't fail Job 1 by overcommitting to Job 2. The builds running on BuildFair are protected from the pyramid pattern that took down Porter Davis and the wave of mid-tier builders that followed.

The honest scope of the contribution. The two structural problems described above are real. They are not the only causes of builder insolvency in Australia, and BuildFair does not address most of the others.

This piece is not arguing that BuildFair fixes housing supply. It's arguing that one specific source of construction failure (the structural payment-system pattern that produces predictable insolvencies even in good economic conditions) is removable, and removing it produces measurably more residential builds completing on time. That's a contribution to the supply problem, not a solution.

BuildFair's trajectory takes it to 1,000 builders by end of 2026, and substantially larger numbers in subsequent years. At those scales, the contribution is meaningful but bounded.

In raw numbers, 1,000 builders running their projects on BuildFair represents a small fraction of the Australian residential construction sector. The sector has tens of thousands of registered builders. BuildFair at 1,000 builders is a meaningful operational base for proving the model and a small share of the overall industry.

The contribution at this scale is to demonstrate that the structural alternative works in residential construction. If the BuildFair-managed builds complete at significantly higher rates and on closer-to-schedule timelines than industry average, that's evidence that the payment-system intervention has the effect we're describing. The evidence then becomes a foundation for two things: more builders adopting the platform voluntarily, and policy reform conversations that have something concrete to point to.

We're not claiming the housing supply problem will be solved by BuildFair reaching 10,000 builders. The problem is too multi-causal and too large for any single platform to solve. We're claiming that the specific failure mode of "otherwise-solvent builders being driven into insolvency by structural payment-system pressure" can be removed for the builds running on the platform, and that the demonstrated removal of that failure mode is the kind of evidence that compounds.

Australia is overdue for a structural conversation about how money moves through residential construction. The current default (owner funds in builder operating accounts, progress payments tied to physical stages, no ringfencing, no protection during the timing gap) was the historical compromise. It has been failing more visibly each year since 2022.

Multiple reform proposals are active. Some focus on stronger trust account requirements for builders. Some focus on expanded owner protection schemes. Some focus on subcontractor protection laws. Some focus on changes to standard contract templates. Each reform has merits, and each is working its way through the relevant state and federal political processes.

BuildFair is one specific implementation of one specific reform direction (regulated escrow with subcontractor payment through the same flow). It is not the only direction, and we don't argue that other directions are wrong. We argue that this specific direction is implementable now, in 2026, without waiting for legislation, because the regulatory frameworks that make it possible (AFSL, AUSTRAC registration, the Corporations Act provisions on segregated funds) already exist. Builders who want to opt into the structural protection now can do so. The legislative reform conversation can continue in parallel.

The relationship between voluntary adoption of structures like BuildFair and statutory reform is complicated. Voluntary adoption can demonstrate that a structural approach works, which strengthens the case for legislating it. Voluntary adoption can also reduce the political pressure for reform by showing that the market is partially solving the problem on its own. We don't have a position on which of these effects will dominate. We're focused on building the platform and proving the mechanism works, and we'll let policy advocates make the policy arguments.
