How progress payments work in Australian residential construction
Progress payments structure how money moves on a residential build. Most owners don't understand them until something goes wrong. Here's how the standard 5-stage schedule works, what each stage actually involves, and where the system breaks.
You sign the building contract. Somewhere in the document is a payment schedule with five or six stages and a percentage next to each. The deposit is paid before work starts. Each subsequent payment is due when the build reaches a defined stage. You don't think about it much at the time. You're focused on the inclusions, the variations, the timeline. The payment schedule is just the financial rhythm of the project.
Six months later, when a stage payment is sitting in dispute and you're trying to work out whether to release the next progress payment to a builder you're starting to worry about, you wish you understood the system better.
This piece is the foundational explanation of how progress payments work in Australian residential construction. What the stages are. What each stage means in practice. Where verification happens. Where the system breaks. What owners should know before signing, during the build, and at each release.
What progress payments are, and why the system uses them
A progress payment is a partial payment of the contract price, made when the build reaches a defined milestone. Instead of the owner paying the full contract value upfront or only at the end, the payment is staged over the project lifecycle. Each stage corresponds to a measurable amount of physical work being completed.
The system exists for two reasons. The first is that the builder needs cashflow to fund the work. A residential build of any meaningful size requires materials, subcontractor labour, and overheads paid weekly or monthly. Without progress payments, the builder would be financing the entire build out of their own working capital, which most builders cannot do at the contract values typical of modern residential construction. The second reason is that owners need protection from paying for work that hasn't been done. Spreading the payment across stages, with each stage tied to physical completion, gives the owner a way to verify they are paying for actual progress.
The two reasons are in tension. Builders want progress payments early and large enough to fund the next phase of work. Owners want to release money only after they can see the work is done. The standard payment schedule used in most Australian residential building contracts is the historical compromise between those two pressures.
The standard 5-stage schedule
Most Australian residential building contracts use a 5-stage payment schedule, sometimes 6 stages depending on the state and the contract template. The two main contract bodies are the Housing Industry Association (HIA) and Master Builders Australia (MBA). Each publishes standard residential building contracts with payment schedules built in. State legislation and consumer protection rules also apply, varying by state, and they sometimes set minimum or maximum stage percentages. The typical breakdown looks like this. The percentages vary by contract and by state, so what's below is a representative average rather than a fixed standard.
Stage 1: Deposit
Five to ten percent of the contract price, paid before any work commences. The deposit covers the builder's initial mobilisation costs, including site survey, council approvals not already paid by the owner, and the start of materials procurement. Most state legislation caps the deposit at five percent for new home construction, though renovation contracts often allow higher deposits.
Stage 2: Base
Ten to fifteen percent of the contract price, due when the slab is poured and cured (or for raised builds, when the foundations and subfloor are complete). The verifiable milestone is concrete in the ground, level, and ready to build on. A council inspector typically signs off on the slab before the builder can claim this stage.
Stage 3: Frame
Fifteen to twenty-five percent, due when the structural frame of the house is complete. Walls and roof framing up, ready for cladding and roofing. The verifiable milestone is a frame that passes structural inspection.
Stage 4: Lock-up
Fifteen to twenty percent, due when the building is weatherproof. External walls clad, roof on, windows and external doors installed. The house can be locked. This is the stage at which the build becomes safe from weather damage and the internal trades (plumbing, electrical, plastering, fit-out) can begin work without exposure.
Stage 5: Fixing
Twenty to twenty-five percent, due when the internal fit-out is complete. Cabinetry installed, internal doors hung, skirting and architraves on, fixtures fitted. The house looks substantially finished but typically isn't yet plumbed, painted, or signed off.
Stage 6: Practical completion
The final ten to twenty percent, paid when the build is complete and the owner can take possession. Practical completion is the legal moment the build is considered finished. There may be a defects list at this point, but the build is functionally done. The owner pays the final stage and receives the keys, with a defects liability period (typically 12 weeks to 6 months depending on the contract) to follow.
Some contracts split fixing and practical completion differently, and some include a separate stage for variations or for extensive landscaping or fit-out work. The core principle is the same: payment is staged against verifiable physical progress.
What actually happens at each stage
The schedule looks neat on paper. The reality of how each stage gets claimed, verified, and paid is messier than the contract suggests.
When the builder reaches a stage, they issue a progress claim to the owner. The progress claim is an invoice for the next stage payment, accompanied by some form of evidence that the stage has been reached. Evidence varies by builder and by contract. Sometimes it's a single line in the claim. Sometimes it's a council inspection report, photographs, an engineer's certificate, or a structural sign-off. Larger and more sophisticated builders typically produce more evidence; smaller and less formal builders typically produce less.
If the owner is funding the build out of pocket, they review the progress claim, satisfy themselves the stage has been reached, and pay. If the owner is funding the build through a construction loan, the progress claim goes to the bank rather than directly to the owner. The bank then arranges for a valuation to verify the stage has been reached, and only releases funds to the builder after the valuation confirms the work. Bank-funded progress payments add a layer of independent verification but also add time. The valuation, the inspection, and the bank's internal processing typically add one to three weeks per stage compared to direct owner funding.
Once the owner or bank releases the stage payment, the funds land in the builder's general operating account. From that account, the builder pays materials suppliers, subcontractors, and the builder's own overheads. Progress payments are not held in trust accounts. They are not ringfenced for the trades who did the work on the current stage. The funds mix with everything else in the builder's account.
This is the part of the system most owners don't realise until something goes wrong.
Where the system breaks
The 5-stage schedule was designed for a smaller, more local industry. The mechanics work when contracts are smaller, when builders work with the same trades for years, and when stages are short enough that timing mismatches don't compound. Modern residential construction has grown out of those conditions, and several structural problems have emerged.
The timing mismatch with subcontractors and suppliers
Subcontractors typically invoice on 14- or 30-day terms. Materials suppliers typically extend 30- to 60-day terms to builders. The next progress payment from the owner or bank might be 6 to 10 weeks away, depending on the stage. If a builder runs even a small stage longer than expected, or if a progress payment is delayed in inspection or bank processing, the gap between what the builder owes others and what they're about to receive becomes acute. Builders without significant cash reserves either pay subcontractors and suppliers late, or stop work, or do both.
The verification gap
Stage progress is verified at the milestone, but not the work that produced it. A builder can pour a slab on time without paying the concreter. The slab passes inspection. The progress payment releases. The concreter is still owed. Verifying the slab does not verify that the trades who built the slab were paid. Owners and banks have no view into whether the people on the ground are being paid out of the funds being released for their work.
The dispute risk at every stage
Each stage is a moment where the owner can dispute the claim. Disputes happen for legitimate reasons: defects, missing documentation, work that's been done out of sequence. They also happen for less legitimate reasons: an owner running out of patience, an owner whose lender has gone quiet and is using disputes to delay payment, an owner with personal financial pressure unrelated to the build. Once a stage is disputed, the next stage cannot proceed in the normal way, the builder's cashflow stalls, and the build often pauses while the dispute is resolved.
The construction loan timing
Bank-funded builds add weeks to each stage. A build with six stages on a construction loan can have six weeks of cumulative bank-driven delay built into the schedule. For a builder operating with thin margins and no cash reserve, those six weeks of delay are funded out of the builder's own working capital. Construction loans, intended to protect owners from paying for work not done, can paradoxically make it more likely the builder runs into financial trouble during the build.
The end-of-job retention problem
Many contracts include a retention clause holding back five percent of each stage payment until the defects liability period expires. The retention is intended to give the owner leverage to enforce defect rectification. The unintended effect is that builders are perpetually carrying retention on multiple jobs, which compounds their working capital exposure. Subcontractors face the same problem when retention is passed down to them.
None of these problems are new. They've been understood for decades. They've persisted because no party in the chain has the leverage or the structure to fix them on their own.
What owners should know
Practical knowledge that helps owners handle progress payments more effectively, before signing, during the build, and at release time.
Read the payment schedule before you sign
The schedule is buried in the contract but it's one of the most consequential parts of the document. Make sure the percentages add up to 100 and that the stages are clearly defined. If a stage is described vaguely ("structure complete" rather than "frame and roof structural inspection passed"), push back during contract review. Vague stages produce disputed claims.
Understand whether your build is owner-funded or bank-funded
The mechanics differ significantly. Bank-funded builds have independent verification but slower release. Owner-funded builds release faster but rely on the owner's own assessment. If you're owner-funded, decide in advance how you'll verify each stage. Independent inspectors cost a few hundred dollars per stage and are usually worth it.
Document the build as it progresses
Photos of each stage, dated. The construction record-keeping you do as an owner is your evidence in any future dispute. Building diaries, defect lists, inspection reports, and copies of all progress claims and invoices. Cloud storage with timestamps is sufficient.
Pay attention to who's getting paid below the builder level
If you can see subcontractors on site and you have any opportunity to ask whether they've been paid for the previous stage, the answers are informative. Subcontractors who've stopped getting paid stop showing up. The first sign of a builder in trouble is often visible at the work site before it's visible in the build progress.
Keep some funds aside for disputes
Almost every residential build has at least one disputed payment claim. If you've planned your finances to release each stage payment exactly on the scheduled date, a dispute creates immediate pressure to settle even when you shouldn't. A small contingency reserve gives you leverage and time.
Don't sign late variations under pressure
Variations are claims against your project that come out of your funds. Builders sometimes batch variations near the end of the build when the owner is most invested and least willing to push back. Each variation should be a discrete decision with documentation, not a list you accept under pressure to finish.
Know your state's owner protection scheme
Each state has a domestic building insurance or compensation scheme. VMIA in Victoria, HBCF in NSW, QBCC in Queensland, similar schemes in WA, SA, Tasmania. Understand what your scheme covers and what it doesn't. Most of these schemes only pay out after the builder has died, become insolvent, or disappeared, and the maximum payouts are often less than the total exposure on a contract.
Where this is heading
The structural problems of the standard progress payment system have been understood for a long time. The reform conversation has accelerated since the high-profile residential builder collapses of recent years. Several directions are emerging.
State governments have tightened the regulation of trust accounts in some states, and reform proposals are active in others. The federal government has stepped up consumer protection messaging in residential construction. Industry bodies have become more vocal about subcontractor protection in particular.
Payment infrastructure has also started to change. A category is emerging where owner funds are held in regulated escrow externally to the builder's operating account, with funds released on verified progress and subcontractors paid through the same flow. Funds for the project are held externally and ringfenced for the project. The builder stops being the small bank between the owner and everyone else who needs paying. BuildFair is one Australian example of this category, built specifically for residential. The change at the heart of the category is the same regardless of which platform implements it: the structure that puts subcontractors and suppliers at risk during the timing gaps in the standard schedule is replaced with a structure that holds the funds outside the gap.
The standard 5-stage schedule will not disappear. It works as a way of staging a build into verifiable milestones, and that mapping is genuinely useful. What changes in this emerging category is where the money sits during the gaps, who has visibility, and who carries the risk when something runs late.
For owners reading this in 2026: the system you sign into still works the way it has for decades. Knowing how it works is the most reliable protection against the failure modes built into it. The next decade will look different. The current one is what you're working through now.

FAQ
Frequently asked questions
How many stages are there in a standard progress payment schedule?
Most Australian residential building contracts use a 5-stage schedule (deposit, base, frame, lock-up, completion) or a 6-stage variant that splits fixing and practical completion. The exact stages depend on the contract template (HIA and MBA are the two most common bodies producing standard residential contracts) and on state-specific consumer protection legislation.
Can my builder demand more than the standard percentages?
State legislation in some states caps stage percentages, particularly for new home construction. Victoria caps the deposit at 5% of contract value for new homes; NSW similarly limits domestic building deposits. Beyond the deposit, the percentages of subsequent stages are usually negotiable but generally fall within an industry-standard range. A builder demanding significantly higher early-stage percentages without justification is unusual and worth questioning during contract negotiation.
What happens if my builder claims a stage that hasn't actually been reached?
You can dispute the progress claim. Under Australian residential building contracts, you typically have a defined window (often 14 days) to either pay the claim or formally dispute it. Disputes that cannot be resolved between owner and builder go to the relevant state tribunal (VCAT in Victoria, NCAT in NSW, QCAT in Queensland) or to adjudication under the state's Security of Payment Act if applicable. Don't pay a disputed stage and then try to recover it; not paying preserves your position.
How does the bank verify a stage on a construction loan?
The bank arranges an inspection, typically by an external valuer or quantity surveyor. The inspector visits the site, confirms the work matches the stage being claimed, and reports back to the bank. The bank releases the funds based on the inspector's report. Each inspection adds 1-3 weeks to the stage release depending on the bank and the inspector's availability. Some banks allow desktop valuations from photographs for smaller progress payments, which is faster.
Can a builder run multiple progress claims at once?
Some builders attempt to combine stages or run progress claims in advance of full stage completion. Whether this is permitted depends on the contract. Most standard contracts require a stage to be reached before the corresponding progress claim can be issued. If your builder is requesting payment for a stage that clearly hasn't been reached, the right response is usually to decline and request the claim be reissued when the stage is genuinely complete.
What's the difference between practical completion and final completion?
Practical completion is the moment the build is considered functionally finished. The owner can take possession. The defects liability period begins. Final completion is when the defects liability period ends and any remaining defects have been rectified. The final stage payment is typically due at practical completion, with retention released at final completion. The retention is the lever that incentivises the builder to return for defect rectification.
What if the builder finishes a stage but hasn't paid the subcontractors who did the work?
This is the structural gap in the standard system. From the contract's perspective, the stage has been reached and the progress payment is due. From the subcontractor's perspective, they're still owed money for work that's already been claimed and paid. Owners have historically had no visibility into whether subcontractors were paid out of the progress payments. The emerging category of regulated escrow platforms aims to address this by paying subcontractors through the same verified-progress flow that releases funds, but the standard contract system does not require it.
How does BuildFair change how progress payments work?
Owner funds are held in regulated custody with our banking partner Kobble. Funds release on verified progress, and subcontractors are paid through the same flow rather than out of the builder's general account. The progress payment schedule and the underlying contract don't change; what changes is where the money sits during the gaps between stages and who can see what's happening to it. Detail is on our Trust & Security page.
Where can I read my state's specific rules on progress payments?
Each state's building authority publishes the consumer protection rules that apply to residential building contracts. Victoria's Domestic Building Contracts Act and Building Act, NSW's Home Building Act, Queensland's Domestic Building Contracts Act, and equivalent legislation in WA, SA, Tasmania, ACT, and NT. Your state building authority's website is usually the most accessible starting point.
