How to Properly Serve a Payment Claim in Australia

You’ve done the work. You’ve supplied the materials. And you’re still waiting for your money. If you’re a tradie or subcontractor in Australia, you know how frustrating that feels. The good news? The Security of Payment legislation in your state exists specifically to help you. But only if you serve your payment claim correctly.

Getting the service right isn’t complicated, but it does matter. A dodgy serve can derail your claim before it even gets traction. Let’s walk through how to do it properly.

What is a Payment Claim and Why Does It Matter?

A payment claim under Australian Security of Payment law isn’t a friendly invoice or a follow-up email. It’s a formal legal document that triggers a statutory process designed to get you paid faster than going to court.

Every Australian state has its own Security of Payment Act (or equivalent). NSW has the Building and Construction Industry Security of Payment Act 1999. Queensland uses the Building Industry Fairness (Security of Payment) Act 2017. Victoria, WA, South Australia, and Tasmania all have their own versions. The details differ slightly, but the core idea is the same: subcontractors and suppliers have a right to claim payment without waiting months for a full court battle.

When you serve a valid payment claim, the recipient (called the respondent) has a set number of business days to respond with a payment schedule or dispute. If they ignore it or don’t pay, you can apply for fast-track adjudication—a quick, low-cost process that forces a decision in your favour or against you in a matter of weeks, not years.

That’s the power of doing it right from the start.

Know Your State’s Rules Before You Serve

This is non-negotiable: read your state’s legislation or get a copy of the rules that apply to your job.

• NSW: Building and Construction Industry Security of Payment Act 1999—respondents have 10 business days to issue a payment schedule
• Queensland: Building Industry Fairness (Security of Payment) Act 2017—respondents have 5 business days
• Victoria: Building and Construction Industry Security of Payment Act 2002—respondents have 10 business days (or 5 for residential)
• Western Australia: Construction Contracts Act 2004—respondents have 10 business days
• South Australia: Security of Payments Act 2009—respondents have 10 business days
• Tasmania: Construction Contracts (Security of Payments) Act 2004—respondents have 10 business days

Different states also have different requirements for what a payment claim must contain, who can serve one, and how it must be served. Don’t assume the process is the same across borders.

Get the Content Right

A valid payment claim must include specific information. Again, this varies by state, but generally you’ll need:

1. A clear statement that it’s a payment claim under the relevant Security of Payment Act
2. Details of the work performed or goods supplied (dates, descriptions, amounts)
3. The contract details (reference number, date, parties involved)
4. The total amount claimed in AUD
5. The due date for payment (usually 5–10 business days from service, depending on your state)
6. Your name, ABN, and contact details
7. The respondent’s name and address
8. A clear statement of your entitlement to payment under the contract

Some states require specific formatting. NSW, for instance, has strict requirements about how the claim is laid out. Get this wrong and the respondent might argue the claim is invalid—which wastes time and gives them an excuse not to respond.

Don’t wing it. Check your state’s legislation or use a service like file a payment claim that handles the formatting and compliance for you.

Serve It the Right Way

How you deliver the claim matters just as much as what’s in it. “Serving” a payment claim doesn’t mean leaving it on someone’s desk and hoping they find it. It means delivering it in a way that’s legally recognised and can be proven.

Accepted methods of service usually include:

• Hand delivery (get a receipt or witness)
• Registered post or courier (get tracking and proof of delivery)
• Email (to a nominated email address on the contract or invoice)
• Email to the head office or site office, if the contract specifies it
• Personal delivery to an authorised representative

The key is proof. Keep evidence that you served it: a delivery confirmation, an email read receipt, a signed acknowledgment, a photo with a timestamp. If the respondent later claims they never got it, you need to show you did your part.

Some states allow service by email if there’s an existing agreement to do so. Others are more strict. Check your state’s rules or ensure you use a method that works across all scenarios—like registered post or courier.

After You Serve—What Happens Next

Once you’ve properly served the claim, the clock starts ticking on the respondent’s obligations. They must either:

• Pay you in full, or
• Issue a payment schedule explaining why they’re not paying in full and when they will, or
• Issue a notice of dispute with reasons why they don’t believe they owe the amount claimed

They have a set number of business days—usually 5 or 10, depending on your state. If they miss that deadline or ignore the claim, you can move to adjudication, which is a faster, more affordable process than litigation.

If they do respond with a payment schedule or dispute, you’ll know where you stand and can decide your next move.

Don’t Leave It to Chance

Serving a payment claim correctly is straightforward, but it’s also easy to trip up if you’re not familiar with your state’s specific rules. A single mistake—wrong formatting, wrong person served, missed deadline—can weaken your position or delay your claim further.

Whether you do it yourself or use a service to help, the investment in getting it right pays off. It shows you’re serious, it triggers the statutory process, and it gives you a clear path forward if the respondent doesn’t cooperate.

You’ve earned your payment. Make sure your claim is bulletproof from day one.
