Unpaid Invoice Debt Recovery Process Australia

You sent the invoice. You waited. You sent a polite reminder. Still nothing. Now you need to recover what you’re owed.

The unpaid invoice debt recovery process in Australia follows a clear escalation path. Start with a formal letter of demand, escalate to a final demand if ignored, then file a claim in the right tribunal or court if the debt remains unpaid. Each step increases pressure while keeping costs proportional to the debt.

When to start the debt recovery process

Not every late payment needs legal escalation. Start the formal debt recovery process when:

• The invoice is overdue by 30+ days — beyond normal payment terms
• Informal reminders have failed — emails and calls ignored
• The amount justifies the effort — typically $500 minimum
• The debt is not genuinely disputed — the work was completed and accepted
• You have clear documentation — invoice, contract, proof of delivery

If the client is claiming defective work, breach of contract, or non-delivery, you may have a dispute rather than a simple debt. Handle those differently.

Step 1: Letter of demand

The letter of demand is your first formal step. It puts the debtor on notice that you are serious about recovery and creates a paper trail if you need to escalate.

What it must include:

• Clear statement of the debt amount
• Invoice number and date
• Brief description of the work or goods supplied
• Payment deadline (typically 7-14 days)
• Consequences of non-payment (tribunal filing, legal costs, interest)
• Your contact details for payment

The debtor realises you are serious and pays rather than face tribunal.

Step 2: Final demand (if ignored)

If the letter of demand is ignored past the deadline, send a final demand. This is your last warning before filing.

Key differences from the first demand:

• Explicitly states this is the final opportunity to pay
• Shorter deadline (typically 7 days)
• Confirms you will file a tribunal or court claim if payment is not received
• May include a breakdown of additional costs (filing fees, interest accrued)

The final demand often prompts payment from debtors who thought you might give up after the first letter.

Step 3: Tribunal or court claim

If both demands are ignored, file a claim. Depending on your state, unpaid invoice claims go to a tribunal or a court. In New South Wales, a business owed money has a debt claim for the Local Court, not NCAT.

Which tribunal or court:

• New South Wales: Local Court of NSW — Small Claims Division up to $20,000; General Division over $20,000 up to $100,000
• Victoria: Victorian Civil and Administrative Tribunal (VCAT) — Civil Claims List
• Queensland: Queensland Civil and Administrative Tribunal (QCAT) — minor civil dispute, up to $25,000
• South Australia: Magistrates Court of SA — minor civil action up to $12,000; general claims up to $100,000
• Western Australia: Magistrates Court of WA — minor case claims up to $10,000; general procedure claims up to $75,000
• Tasmania: Magistrates Court of Tasmania (Civil Division) — up to $50,000
• Australian Capital Territory: ACT Civil and Administrative Tribunal (ACAT) — civil disputes up to $25,000
• Northern Territory: NT Civil and Administrative Tribunal (NTCAT) — small claims up to $25,000

What you need to file:

• Completed application form or statement of claim (varies by state)
• Copy of the invoice
• Copy of any contract or terms and conditions
• Proof of delivery or completion (delivery docket, signed acceptance, photos)
• Copies of your letter of demand and final demand
• Proof of service (registered post receipt, email delivery confirmation)
• Filing fee (filing fees change each 1 July; check the current fee on the tribunal’s or court’s website before you file)

What happens next:

Some states offer mediation first. If the debtor does not defend, you can usually obtain a default judgment.

Step 4: Judgment and enforcement

If you win at tribunal (or the debtor defaults), you receive a judgment or order requiring payment. The debtor now has a court debt.

If they still don’t pay:

You can enforce the judgment through:

• Garnishee order — intercepts money from their bank account or wages
• Warrant for seizure and sale — sheriff seizes and sells assets
• Examination summons — debtor must attend court and disclose their financial position

Enforcement costs are usually recoverable from the debtor, but enforcement is only effective if the debtor has assets or income to target.

Special case: Company debtors over $4,000

If the debtor is a registered company (Pty Ltd or Ltd) and owes $4,000 or more, you have a powerful alternative to tribunal: the statutory demand.

A statutory demand under the Corporations Act gives the company 21 days to pay or face wind-up proceedings. It often prompts immediate payment because the consequences are severe.

Requirements:

• Debt must be $4,000 minimum
• Debtor must be a registered company (check ASIC)
• Debt must be liquidated (specific amount, not estimated)
• Debt must not be genuinely disputed

Timeline: How long does debt recovery take?

Typical timeline for the full escalation path:

• Letter of demand: 7-14 days response time
• Final demand: 7 days response time
• Filing to hearing: depends on the tribunal or court, and on whether the debtor defends
• Enforcement (if required): depends on the method

A tribunal or court claim is the exception, not the rule.

Costs you can recover

You can usually recover:

• The invoice amount — the principal debt
• Interest — either contractual interest (if your terms allow it) or statutory interest post-judgment
• Filing fee — if the tribunal or court orders it
• Reasonable enforcement costs — if you need to enforce the judgment

You cannot usually recover:

• Your own time spent chasing the debt
• Document preparation fees (though tribunals sometimes allow reasonable costs)
• Legal costs (often limited or not allowed in small claims; check the rules of your tribunal or court)

Frequently Asked Questions

How long should I wait before sending a letter of demand for an unpaid invoice?

Send a letter of demand once the invoice is 30+ days overdue and informal reminders have failed. Waiting longer reduces your chances of recovery as the debtor’s financial position may deteriorate.

Can I charge interest on an unpaid invoice in Australia?

Yes, if your contract or terms and conditions include an interest clause. Without a contractual right, interest depends on the rules of the tribunal or court that hears your claim.

What happens if the debtor ignores my letter of demand?

Send a final demand with a shorter deadline (7 days). If that is also ignored, file a claim in your state’s tribunal or court. The letter of demand creates a paper trail showing you gave the debtor a reasonable opportunity to pay before escalating.

Do I need a lawyer to recover an unpaid invoice in Australia?

No. For small claims within your state’s tribunal or court limit, the process is designed for self-representation. Claim Done prepares the documents, and you lodge them yourself.

What if the debtor is a company and owes more than $4,000?

You can serve a statutory demand under the Corporations Act instead of going to tribunal. This gives the company 21 days to pay or face wind-up proceedings, and often prompts faster payment than tribunal.
