TL;DR: A progress claim is a staged demand for payment as work completes, and in Australia it sits on two legal rails: your contract and the security of payment legislation in your state or territory. Structure your payment stages before you sign, claim on time every time, back every claim with evidence (photos, variations in writing, a clear breakdown) and respond to disputes inside the statutory timeframes. Builders who treat claiming as a fixed weekly discipline, not an end-of-month chore, are the ones who don't end up funding the client's build from their own pocket.

Cash kills more building businesses than bad workmanship ever has. You can be profitable on paper and still go under because the money arrives three stages behind the work. That's why progress claims matter, and it's why searching progress claims construction Australia turns up so much conflicting advice: every state runs its own security of payment act, domestic and commercial jobs follow different rules, and most of what's written is by lawyers for lawyers. This guide is the builder's version: how claims actually work, how to structure them so you're never cash-negative on a job, and how to keep them out of dispute.

What a progress claim actually is (and what it isn't)

A progress claim is a formal request for payment for work completed (and sometimes materials supplied) up to a point in the job. It is not an invoice in the everyday sense, and the difference matters.

Under the security of payment legislation that exists in every Australian state and territory, a valid payment claim triggers statutory rights. Once you serve one, the clock starts: the other side has a fixed window to respond with a payment schedule saying what they'll pay and why, and if they don't respond at all, in most jurisdictions the full claimed amount becomes a debt they owe you. Miss the formalities, though, and you may have no statutory protection at all, just a polite request someone can ignore for 90 days.

A valid claim generally needs to:

• identify the construction work (or related goods and services) it covers
• state the amount you say is payable
• be served on or after the reference date your contract sets (or the default date the act provides)
• meet any state-specific formalities, such as stating that it's made under the relevant act where required

One more distinction worth locking in: a payment claim and a tax invoice are not automatically the same document. If you're registered for GST, you still need to issue a tax invoice so the client can claim credits and your BAS lines up. Many builders combine the two; just make sure the combined document meets both sets of requirements.

Progress claims construction Australia wide: the rules by state

There is no single national act. Each state and territory has its own security of payment legislation, and while they've converged over the years, the details differ enough to bite you.

In NSW, the Building and Construction Industry Security of Payment Act 1999 gives anyone carrying out construction work under a construction contract a statutory right to progress payments. A respondent who wants to pay less than the claimed amount must serve a payment schedule within 10 business days, and maximum payment terms apply down the contracting chain. Victoria has its own act from 2002, Queensland folded security of payment into the Building Industry Fairness (Security of Payment) Act 2017, and WA replaced its older regime with a new act in 2021. The mechanics rhyme: claim, schedule, then fast-track adjudication if you disagree.

Two carve-outs matter for residential builders:

• Owner-occupier jobs are often excluded. In several states, contracts with a homeowner who lives in (or intends to live in) the property fall outside the security of payment regime. Your rights there come from the contract and domestic building legislation instead.
• Domestic building laws cap and stage payments. Victoria's Domestic Building Contracts Act 1995 is the clearest example: for major domestic building work under the standard method, the deposit is capped at 5% for contracts over $20,000, then base stage 10%, frame 15%, lock-up 35%, fixing 25%, with the balance on completion. Other states have their own deposit caps and staging rules, so check yours before you print a payment schedule off the internet.

The practical takeaway: know which regime your job sits under before you sign, because it decides what you can claim, when, and what happens if the client goes quiet.

Structure the payment schedule before you sign, not after

Most cash flow pain is baked in at contract stage. By the time you're chasing a late claim, the structural mistake was made months earlier.

The principle is simple: each stage payment should cover the cost of the work in that stage plus a fair share of margin, so you are never significantly cash-negative. Where the staging is up for negotiation (commercial work, or domestic work in states that allow an agreed schedule), work backwards from your cost curve. If your frame-stage outlay is heavy because of truss and steel deliveries, the frame claim needs to reflect that. On longer jobs, shorter claim cycles beat bigger stages: monthly claims are standard on commercial work, and there's nothing stopping you negotiating monthly claims on a long renovation where the law allows it.

Watch for these traps in contracts put in front of you:

• Back-loaded schedules where a fat completion payment leaves you funding the last two months of the job. Kept within any legal staging caps, money should track work.
• Vague stage definitions. "Lock-up" means something specific in most standard contracts; a home-made definition ("substantially enclosed") is a dispute waiting for a rainy day.
• Long payment terms stacked on long claim cycles. A monthly claim plus 30-day terms means you're carrying up to 60 days of costs. Statutory maximum terms help, but the contract shouldn't need rescuing by legislation.
• Pay-when-paid clauses. These are void under security of payment legislation. If a head contractor tells you they'll pay you when the client pays them, the act says otherwise.

If the market softens, this discipline matters more, not less. When margins tighten the way the industry outlooks suggest they might, cash timing is what separates the builders who ride it out; the housing market outlook for 2026 covers what that environment looks like for quoting.

Write claims that get paid, not queried

A disputed claim is a late claim, even if you eventually win. Most disputes start not with bad faith but with a claim the other side can't verify. Make verification effortless.

A claim that gets paid usually has:

1. A clear breakdown. Line items against the contract stages or the schedule of works, showing percentage complete against each, this claim versus previous claims versus contract sum. One number on a page invites a phone call; a breakdown invites a signature.
2. Evidence attached. Date-stamped photos of the work claimed are the cheapest dispute insurance there is. A frame-stage claim with 15 photos of the completed frame is hard to argue with. If your site photo habits are patchy, our guide to construction site photo documentation is worth the ten minutes.
3. Variations claimed separately and already approved. The single biggest source of claim disputes is variation work billed for the first time inside a progress claim. Get the variation signed (or at least acknowledged in writing) when it's agreed, then include it as its own line with the reference.
4. The formalities done. Right entity name, right service method, served on or after the reference date, endorsed under the act where your state requires it. Boring, and decisive at adjudication.

Then claim on time, every time. Set the reference dates in your calendar the day you sign the contract. A builder who claims like clockwork trains the client to pay like clockwork.

When a claim goes bad: schedules, adjudication and disputes

If the other side serves a payment schedule for less than you claimed, read their reasons carefully; they're generally locked into those reasons at adjudication. If they serve nothing inside the statutory window, in most states the full claimed amount becomes a debt due, and you can pursue it or move to adjudication.

Adjudication is the security of payment regime's engine room. It's fast (decisions typically land within weeks, not the year a court case takes), it's on the papers, and the decision is binding on an interim basis, meaning the money moves now and anyone who wants to re-argue it later does so in court with the cash already in your account. The strict timeframes cut both ways: miss a deadline as a claimant and your application can fail on a technicality, which is another reason the paperwork discipline above matters.

Not every fight belongs in adjudication. A relationship-salvageable disagreement over one variation is often better handled with a site meeting and a marked-up drawing. For the escalation ladder from phone call to tribunal, see our guide on how to handle construction disputes in Australia. And remember defects are not a free pass to withhold everything: a client's right to withhold is generally limited to the reasonable cost of rectifying identified defects, not the whole claim. Your exposure on defects runs on its own track, covered in our guide to construction defect liability in Australia.

Retentions, GST and the slow leaks

Two other places money quietly goes missing:

Retentions. On commercial work it's common for the principal or head contractor to hold retention, often 5% of the contract value, with half typically released at practical completion and the rest after the defects liability period. Track it. Retention that nobody claims at the end of defects liability is a gift to the other side, and across a few jobs it adds up to a ute. Diarise the release dates the day the contract is signed, and check whether your state requires retention money to be held in trust, as some now do for certain contracts.

GST and BAS timing. If you're on cash accounting, you account for GST when the money lands, which is kind to cash flow. On accruals, GST can fall due off the invoice before you've been paid, so a big claim issued in the last week of a quarter can create a BAS bill ahead of the cash. Time large claims with your BAS cycle in mind, and if you're unsure which method you're on, that's a five-minute conversation with your accountant that's worth having this week.

Frequently asked questions

How often can I make a progress claim?
Whatever your contract says, subject to your state's rules. Under most security of payment acts, if the contract is silent you still get a default right to claim monthly. On domestic building work, staging rules or caps in your state's domestic building legislation may fix the claim points for you.

Can a client just refuse to pay a progress claim?
Not silently, if the job is covered by security of payment legislation. They must serve a payment schedule within the statutory window (10 business days in NSW) stating what they'll pay and why. No schedule generally means the full amount becomes a debt due, and you can head to adjudication or court to recover it.

Do progress claims include GST?
If you're registered for GST, yes, construction work is a taxable supply, so claim the GST-inclusive amount and show the GST component. Make sure the client ends up holding a valid tax invoice, whether that's the claim itself or a separate document.

What deposit can I take before work starts?
It's capped for domestic building work and the cap varies by state. Victoria caps it at 5% for major domestic building contracts over $20,000, and other states have their own limits (10% figures are common for smaller contracts). Check your state's domestic building legislation rather than assuming.

Can I suspend work if a claim isn't paid?
Under most security of payment acts, yes, after following the notice procedure: typically written notice of intention to suspend, then a further short period before you down tools. Suspending without following the steps can put you in breach, so get the notices right or get advice first.

Keep the cash moving

Progress claims aren't paperwork that happens after the real work. On a building job, they are the real work of staying solvent: stage the contract so money tracks cost, claim on schedule with evidence attached, chase the statutory rights the moment a claim goes quiet and never let retentions or variations leak. None of it is complicated. All of it is easier when the job records live in one place, which is what construction project management software is actually for.
