If you’re a tradie or subcontractor chasing unpaid invoices across Australia, you need to know one thing: the state you work in matters. A lot.
Each Australian state and territory has its own Security of Payment legislation. While they all aim to protect contractors from cash-flow collapse, the rules—deadlines, dispute procedures, and enforcement mechanisms—differ enough to catch you out if you’re not careful.
This guide walks you through the key differences between Queensland, New South Wales, and Victoria. These three states represent most of Australia’s construction activity, and understanding how their laws diverge could save you weeks and hundreds of dollars.
What is Security of Payment legislation, and why does it matter?
Security of Payment laws exist to protect you. They give subcontractors and tradies a fast-track mechanism to force payment disputes to independent adjudication, without needing to sue. You don’t wait 12 months in court. You can have a binding decision in weeks.
But the pathway to that decision—and what “binding” actually means—changes from state to state. That’s why comparing them is critical.
How long do I have to lodge a payment claim?
| State | Legislation | Claim lodgement window | Key note |
|---|---|---|---|
| NSW | Building and Construction Industry Security of Payment Act 1999 | 12 months from the date the claim relates to | Can claim progressively; no requirement to wait for final completion |
| QLD | Building Industry Fairness (Security of Payment) Act 2017 | 12 months from the date the claim relates to | Can claim for progress payments; same 12-month window applies |
| VIC | Building and Construction Industry Security of Payment Act 2002 | 12 months from the date the claim relates to | Most restrictive on what qualifies as a valid claim; stricter requirements on documentation |
The headline: All three states give you 12 months. But don’t treat this as a licence to delay. The sooner you lodge, the sooner you can enforce a decision.
What happens after I lodge a claim?
Once you submit a payment claim, the other party (the respondent) has a set time to respond. This is where state rules diverge meaningfully.
NSW: The 10-day payment schedule
Under section 14 of the NSW Security of Payment Act 1999, a respondent must provide a payment schedule within 10 business days of receiving your claim. The payment schedule must state what they will or won’t pay, and why.
If they don’t provide one, you can immediately apply for adjudication. This is a powerful position: silence = fast-track to a binding decision.
QLD: The 10-day response period
Queensland’s 2017 Act uses similar mechanics. Section 38 requires the respondent to issue a payment schedule within 10 business days. The timeline is identical to NSW, but the documentation requirements are slightly different—QLD is marginally more prescriptive about what must appear in the schedule.
VIC: The 10-day response, with tighter claim rules
Victoria also mandates a 10-day response (section 14 of the Victorian Act). However, Victoria’s legislation is stricter on what qualifies as a valid claim in the first place. Your claim documentation must meet higher formal standards, and the respondent can reject your claim as invalid more easily in Victoria than in NSW or QLD.
This means your claim upfront preparation matters more in Victoria.
What are the key differences in adjudication?
If the respondent disputes your claim, adjudication is the next step. This is where the states’ approaches diverge most sharply.
| State | Adjudication timeline | Adjudicator’s scope | Decision is binding? |
|---|---|---|---|
| NSW | 42 days from lodging the adjudication application | Broad; can consider all evidence and arguments | Binding and enforceable immediately; respondent must pay while retaining rights to later challenge |
| QLD | 28 days from lodging the application (faster) | Broad but must apply the contract and legislation strictly | Binding and enforceable; same “pay now, argue later” principle |
| VIC | 42 days from lodging the application | More limited; focuses on the claim as initially lodged; stricter about scope creep | Binding and enforceable, but respondent has more grounds to challenge validity later |
Critical point: In all three states, an adjudicator’s decision is binding and must be paid immediately, even if the respondent intends to challenge it later. This is the core protection the legislation offers.
How do I actually lodge a payment claim?
The rules say what you must include—but formatting and delivery matter. Your claim must:
- Identify the claimant and respondent clearly
- State the claim amount
- Describe the work or materials supplied
- State the date the claim relates to
- Include supporting invoices, quotes, or progress schedules (NSW and QLD are more forgiving here; VIC is stricter)
- Be served properly—usually by email, post, or hand delivery, depending on the contract
Getting the formalities right matters because a defective claim can be rejected outright, especially in Victoria. Many tradies lose months by lodging incomplete claims.
If you want to avoid administrative delays, file a payment claim online using a tool built around these statutory requirements. This removes guesswork on format and content.
What happens if the respondent doesn’t pay after adjudication?
An adjudicator’s decision is binding, but it’s not self-executing. If the respondent refuses to pay, you’ll need to enforce the decision in court. This is the same across all states:
- Obtain the adjudication decision
- Apply to the court (District Court or Supreme Court, depending on the amount) for enforcement
- The court can order payment, interest, and costs
Enforcement is usually straightforward—the decision is already binding—but it does require a court application. This step is faster and cheaper than litigation, but it’s not automatic.
Do all Australian states have Security of Payment laws?
Yes. Every state and territory has legislation, though not all are identical:
- NSW: Building and Construction Industry Security of Payment Act 1999
- QLD: Building Industry Fairness (Security of Payment) Act 2017
- VIC: Building and Construction Industry Security of Payment Act 2002
- WA: Construction Contracts Act 2004
- SA: Building and Construction Industry Security of Payment Act 2009
- TAS: Building and Construction Industry Security of Payment Act 2009
- NT: Construction Contracts (Security of Payments) Act 2004
- ACT: Building and Construction Industry (Security of Payment) Act 2009
If you work in WA, SA, TAS, NT, or ACT, the principles are similar to NSW, QLD, and VIC—but specific deadlines and procedural rules differ. Always check your state’s legislation or seek advice before lodging a claim outside the three largest states.
What’s the fastest state to get paid through adjudication?
Queensland is the fastest. Section 17D of the Queensland Act mandates a 28-day adjudication timeline, compared to 42 days in NSW and Victoria. This means you can have a binding, enforceable decision in less than 6 weeks from lodging the adjudication application.
NSW and Victoria give the adjudicator 42 days. In practice, most decisions arrive faster, but 42 days is the statutory maximum.
Can I claim for GST and interest?
Yes, in all three states. Your payment claim can include:
- The contract price (or quantum meruit if there’s no fixed price)
- GST (if you’re registered)
- Interest (calculated from the due date to the claim date, usually at the rate agreed in the contract or at a statutory default rate)
- Variations and claims for delay or additional work (if documented)
Documentation is key. Victoria especially will scrutinise your supporting evidence. Make sure every invoice, progress report, or variation order is dated and referenced clearly.
What if there’s no written contract?
You can still lodge a claim. All three states recognise oral contracts and implied contracts. However, without written terms, disputes over price, scope, and liability become harder to resolve in your favour. Adjudicators will rely on email chains, quotes, and progress schedules as evidence.
If you’re working without a written contract now, start one. Future claims will be stronger.
Are there any exclusions from Security of Payment protection?
Yes. Work excluded from the Acts varies slightly by state, but commonly excluded work includes:
- Residential work (generally, though there are exceptions and recent reforms)
- Work on premises where the principal is a natural person not carrying on a business
- Work under contracts with certain government agencies (varies by state)
- Work on contracts worth less than a threshold amount (varies)
Check whether your work falls within the Act before relying on it. If you’re unsure, err on the side of caution and lodge a claim anyway—the worst that happens is the adjudicator declines jurisdiction, not that you’re worse off.
What should I do if I’m owed money right now?
Take these steps in order:
- Gather evidence: Collect invoices, contracts, progress schedules, emails, and quotes. Ensure dates and amounts are clear.
- Send a reminder: A formal letter (email is fine) asking for payment by a set date. Keep a copy.
- Check your state’s Act: Verify your work is covered and you’re within the 12-month window.
- Prepare your claim: List the work, dates, amounts, and GST. Attach supporting documents.
- Serve the claim: Deliver it to the respondent (builder, head contractor, or developer) by the method specified in your contract.
- Wait for a response: The respondent has 10 business days to issue a payment schedule.
- If they don’t pay or dispute it: Apply for adjudication within the timeframe specified in your state’s Act (usually within a defined period after the payment schedule is due).
This process is self-service, but it must be done correctly. If your claim is formally defective, it will be rejected, and you’ll lose time.

Frequently Asked Questions
Q: What’s the difference between a payment claim and an invoice?
An invoice is a request for payment under your contract. A payment claim is a statutory document lodged under Security of Payment legislation. A payment claim has formal requirements (claimant identification, date, amount, description of work) and triggers statutory obligations on the respondent to respond. An invoice alone doesn’t trigger these protections. If you’re chasing an unpaid invoice, converting it to a formal payment claim gives you access to adjudication.
Q: Do I need a lawyer to lodge a payment claim?
No. The legislation is designed to be accessible to tradies and small contractors without legal representation. However, getting the format and content right matters, especially in Victoria where claims are rejected more often. If your claim is over AUD 50,000 or the dispute is complex, legal advice may save you money. For straightforward claims, self-service tools can guide you through the process accurately.
Q: What happens if the respondent says they’ll pay “next month” after I serve a claim?
If you’re within the statutory process, accept payment and document it. If they’ve issued a payment schedule that acknowledges the debt but delays payment, you’re still entitled to apply for adjudication to force earlier payment. The existence of a dispute (or even an agreement to pay later) doesn’t stop you pursuing adjudication. Your priority is getting paid on your terms, not theirs.
Q: Can I claim for work under a subcontract to a subcontractor (work further down the chain)?
This depends on the contract structure. In NSW and QLD, you can claim against the party you contracted with directly. Claims between lower-tier subcontractors and project owners are more complex and depend on specific contractual terms. Victoria has additional restrictions. If you’re several tiers down the chain, seek advice before lodging, as your claim may not be valid under the legislation.
Q: If I lodge a claim and lose the adjudication, do I have to pay the respondent’s costs?
Adjudication costs are not typically recoverable by either party under Security of Payment legislation in NSW, QLD, or Victoria. If you proceed to court enforcement or if the respondent sues you separately, costs may be awarded based on the outcome. The statutory process is designed to be low-cost for both sides; use it when your claim is strong, not speculatively.
