How to take an unpaid invoice to the small claims tribunal in Australia

If a customer will not pay after a letter of demand, you can file a claim at your state's civil and administrative tribunal. Filing fees range from approximately $50 to $500 depending on your state and the amount owed. You do not need a lawyer. The tribunal makes a binding decision, and you can enforce it as a court judgment if the customer still refuses to pay.

When is the tribunal the right path for an unpaid trade invoice?

The tribunal is the right step when you have done the work, sent the invoice, chased it up, and sent a formal letter of demand, and the customer still has not paid. Before you file, make sure these three things are true:

• You have a letter of demand on record. Most state tribunals expect you to have sent one and given the customer a reasonable deadline (usually 14 days) before they will hear your case
• The amount is within the tribunal's small claims limit. Each state sets its own cap. If the amount exceeds it, you may need the tribunal's general list or a court instead
• The dispute is about money owed, not defective work. If the customer is withholding payment because they claim the work is defective, the hearing will address both the debt and the alleged defect, so bring evidence of the quality of your work

For the steps before this point, including how to write a letter of demand and chase the invoice without burning the relationship, see our guide to chasing unpaid invoices politely.

If the customer simply refuses to pay the final invoice and you are not sure whether the tribunal or another path is better, our guide to handling a customer who refuses to pay walks through the decision tree.

Which tribunal do I file at in my state?

Every Australian state and territory has a civil and administrative tribunal that handles small claims, including unpaid trade invoices. You do not need a lawyer. As VCAT puts it: "We are a tribunal, which means we're less formal than a court." The same applies across all state tribunals: a tribunal member (not a judge) hears both sides and makes a binding decision.

If the amount owed exceeds your state's small claims limit, the claim can usually go to the same tribunal's general or building list (with higher limits) or to the Magistrates Court or Local Court. Filing fees are higher for larger claims. We will not invent numbers for your business, and we do not promise a capture or conversion rate. Treat the figures above as a directional industry estimate, not a promise. Jurisdictional limits change; verify the current cap with your state tribunal before filing.

What evidence do I need to bring?

The tribunal decides on evidence, not arguments. The stronger and more organised your documentation, the faster and more clearly the hearing goes. Bring originals and at least two copies of everything (one for the tribunal, one for the respondent).

1. The signed contract or written quote. This proves what work was agreed, the price, and the payment terms. If you have no written contract, bring the quote, any text messages or emails where the customer accepted the price, and any invoices that describe the scope
2. The invoice and any payment reminders. Show the original invoice, the due date, and every reminder you sent (email, SMS, app notification). Timestamps matter
3. The letter of demand with proof of delivery. A copy of the letter you sent, plus the registered-post receipt or tracking confirmation showing it was delivered. If you also emailed it, include the email
4. Photos of the completed work. Before-and-after photos, progress photos, and any final walkthrough or sign-off. If the customer is disputing quality, these are critical
5. All written communication about the dispute. Every text, email, app message, or letter between you and the customer about the payment or the work. Print them in date order. Do not edit or omit messages that look unfavourable: the other party will likely bring their copies

If the job was done under a formal building contract (residential work above state thresholds), bring the contract with its progress-payment schedule and any signed variation orders. Missing variation paperwork is the most common reason a tribunal reduces the amount awarded to a tradie.

How do I file a claim?

Most state tribunals accept online applications. The process is similar across states:

1. Go to your state tribunal's website and find the application form. NCAT, VCAT, QCAT and SACAT all have online portals. WA and TAS route through the Magistrates Court for smaller claims
2. Fill in the application. You will need the customer's full name and address (the respondent), the amount claimed, a brief description of the dispute, and your contact details
3. Pay the filing fee. Fees vary by state and claim amount. Budget $50 to $500 depending on the tribunal and the size of the claim. The tribunal can order the respondent to reimburse your filing fee if you win
4. Serve the application on the respondent. Some tribunals handle service for you; others require you to serve the documents yourself (by post, email, or in person, depending on tribunal rules)
5. Wait for the hearing date. You will receive a date, usually four to twelve weeks from filing. Some tribunals schedule a mediation or conciliation session first

What happens at the hearing?

Tribunal hearings for unpaid invoices are short and informal. Expect the hearing to last one to three hours. Here is what to expect:

• You present your case first. Explain the work you did, show the contract or agreement, present the invoice, show that you sent a letter of demand, and present your evidence of completed work
• The respondent presents their side. They may argue the work was not completed, was defective, or that the amount is wrong. Listen and take notes rather than interrupting
• The tribunal member asks questions. They may ask both parties to clarify facts, explain gaps in the evidence, or comment on the other party's claims
• The tribunal makes a decision. Some tribunals issue the decision on the day; others reserve and send it in writing within a few weeks. The decision is binding

Dress neatly, arrive early, and be factual rather than emotional. The tribunal member has seen hundreds of these disputes. They are looking at whether a contract existed, whether the work was done to an acceptable standard, and whether the amount is owed.

How do I enforce a tribunal order if the customer still does not pay?

A tribunal order is legally binding, but it does not guarantee payment. If the customer ignores the order, you need to enforce it. The process varies by state but follows a similar pattern:

1. Register the order. If the tribunal order is not automatically registered with the court, file it with the relevant court (usually the Local Court in NSW, Magistrates Court in other states) to convert it to a court judgment
2. Request enforcement. Once registered, you can apply for enforcement options including a garnishee order (money taken directly from the debtor's bank account or wages), a property seizure order (a sheriff seizes goods to sell), or an examination order (the debtor is ordered to attend court and disclose their financial position)
3. Pay the enforcement fee. There is a fee for each enforcement application (typically $50 to $150), which is added to the amount the debtor owes

If the customer is a company that appears to be insolvent (no assets, not trading), enforcement may not recover the debt. In that case, a statutory demand or winding-up application is an option, but the costs escalate and legal advice is worthwhile at that point.

Is Security of Payment a better option than the tribunal?

For construction contracts, adjudication under your state's Security of Payment (SOP) Act may be faster and more effective than the tribunal.

SOP gives anyone who carries out construction work a statutory right to progress payments and a fast, interim-binding adjudication process. The key differences from the tribunal:

• Speed. SOP adjudication runs on compressed statutory timeframes, typically weeks rather than months, compared to four to twelve weeks for a tribunal hearing
• Scope. SOP covers construction work and related goods and services. If you are a tradie doing building or trade work under a construction contract, it is likely covered
• Interim binding. The adjudicator's decision is binding unless overturned by a court. The amount determined can be recovered as a debt immediately
• Payment schedules. If the customer does not serve a payment schedule within the statutory window after receiving your payment claim, they are liable for the full claimed amount. This is a powerful incentive for the customer to respond

SOP adjudication costs more than a tribunal filing fee (adjudicator fees apply), but for larger amounts on construction contracts, it is often the faster and more direct path. Each state has its own SOP Act with slightly different claim and response windows, so check the rules for your jurisdiction.

What does the Australian Consumer Law say about this?

The Australian Consumer Law (ACL), Schedule 2 of the Competition and Consumer Act 2010, gives consumers automatic guarantees that services must be performed with due care and skill, fit for purpose, and within a reasonable time. These consumer guarantees are automatic and non-excludable: a business cannot contract out of them, and a "no refunds" sign does not override them.

This matters in a tribunal hearing because if the customer argues the work was defective, they may counterclaim under the consumer guarantees. If you did the work properly, the guarantees work in your favour: you performed with due care and skill, and the customer owes you the agreed price.

Two ACL provisions come up most often in trade invoice disputes:

• Consumer guarantees (sections 51 to 63). The customer cannot refuse to pay simply because they changed their mind. But if the work genuinely did not meet the guarantee of due care and skill, the tribunal may reduce the amount owed or order rectification
• Unfair contract terms (UCT). Since 09/11/2023, including or relying on an unfair term in a standard-form small-business contract is illegal and penalised. If your quote or job terms include one-sided clauses (such as broad exclusions of liability, unilateral right to vary the price, or excessive cancellation fees), the tribunal can declare those terms void. Company penalties for UCT contraventions (for conduct on or after 28/03/2026) can reach the greater of $100,000,000, three times the benefit obtained, or 30% of adjusted turnover (statutory maximum, per the ACCC). For an individual, the maximum is up to $2,500,000 per contravention. These figures are statutory maxima, not predictions for any individual case

The practical takeaway: keep your contract terms fair, do the work properly, and document everything. This makes the tribunal process straightforward and protects you against counterclaims.

How can automation help you avoid getting to this point?

The best tribunal claim is the one you never need to file. Most unpaid invoices are not disputes: they are invoices that slipped off the customer's radar. A system that sends the invoice on completion, follows up at 7 and 14 days, and escalates to a letter of demand template at 30 days catches most late payers before the relationship sours. For a walkthrough of automating invoices and reminders from your phone, see our guide to automating invoices and payment reminders.

Taking a deposit before starting work also protects you. If the customer has already paid 5% to 10% upfront (within the deposit cap your state allows), they are far less likely to walk away from the final invoice. And if a variation changes the scope mid-job, getting it signed in writing before doing the extra work is the single most important thing you can do to protect the full amount owed.
