ACT Security of Payment: Practical Steps for Subcontractors

You’ve finished the job. The invoice is overdue. The head contractor isn’t returning calls. If you’re a subcontractor or tradie working in the ACT, you’ve got legal rights—and they’re stronger than most people realise. The ACT Security of Payment Act 2009 exists specifically to get you paid faster, without waiting months for court proceedings. Here’s how to use it.

Understand the ACT Security of Payment Act 2009

Unlike some states, the ACT has its own legislation: the Security of Payment Act 2009. It applies to construction work and related services in the territory. The core idea is simple: if you’ve done the work or supplied materials, you have the right to claim payment quickly and without needing to prove your entire case upfront.

This Act gives you access to fast-track adjudication—a process that sits between negotiation and court. An independent adjudicator can decide disputes within weeks, not months. The head contractor or principal must follow strict timelines to respond, and they can’t ignore your claim without consequence.

The key protection: you don’t need a signed contract or perfect paperwork to make a claim. You just need evidence that you’ve done construction work or supplied goods for a construction project in the ACT, and that payment is due.

Get Your Documents Ready Before You Claim

Before you lodge a claim, gather what you have. You’ll need to show:

• Your invoice or payment claim (date, amount, description of work)
• Evidence of the work done (photos, delivery dockets, timesheets, emails confirming scope)
• Proof the money is owed (contract, purchase order, email agreement, or even just SMS correspondence)
• Details of who owes you (the head contractor, principal contractor, or developer—whoever hired you)
• Your payment terms (e.g., “due within 14 days of invoice”)

You don’t need everything perfect. The ACT Act doesn’t require rigid formality. But the clearer your paper trail, the stronger your position. If you’ve got emails, texts, or site photos showing the work was done, keep them. If you have a contract—even a rough one—that’s gold.

Follow the Practical Steps to File Your Claim

Once you’ve gathered your documents, the process has clear steps. Here’s what happens:

1. Prepare your payment claim. Write it clearly: state what work you did, when, how much you’re owed, and your contract terms. Include a summary of the documents you’re attaching.
2. Serve the claim on the right person. Work out who is legally responsible to pay you. This is usually the head contractor, not the site supervisor. You can serve it by hand, email, or post—the Act accepts multiple methods.
3. Give them time to respond. Under the ACT Act, the respondent has 10 business days to serve a payment schedule—that’s a formal document saying how much they’ll pay and when.
4. Check their response (or lack of one). If they don’t respond, you can push straight to adjudication. If they do respond with a payment schedule, you can either accept it or dispute it.
5. Escalate to adjudication if needed. If you can’t reach agreement, you can apply for fast-track adjudication. An independent adjudicator will decide the claim within a tight timeframe.

The entire process, from claim to adjudication decision, typically takes 4–8 weeks. That’s far quicker than suing in court.

Make Your Claim Count

When you file a payment claim, be specific. Don’t say “work done on site”—say “supply and installation of 200 square metres of plasterboard lining, western elevation, completed 15 August 2024, as per Purchase Order PO-2847.” Dates, quantities, and references matter. Adjudicators need to understand exactly what you’ve claimed.

Include a clear breakdown of costs. If you’re claiming AUD 8,500 for labour and materials, show the split. If part of the invoice is disputed and part isn’t, separate them. Clarity saves time and strengthens your hand.

Don’t overstate. Stick to what you actually did and what you’re actually owed. Inflating claims weakens credibility and can backfire during adjudication.

What Happens Next

Many debtors choose to pay or settle rather than face fast-track adjudication. Once a formal claim is on record, the pressure shifts. They know you’re serious, you’ve got the paperwork, and the process is moving.

If adjudication happens, the adjudicator’s decision is binding (unless there’s a later court challenge, which is rare). The respondent must pay the awarded amount within a set timeframe. If they don’t, you can take enforcement action—and that’s where the real weight of the law comes in.

The point: the ACT Security of Payment Act exists because construction has a cash-flow problem, and small tradies shouldn’t have to wait six months or go broke waiting for payment. It’s there for you. Use it.

Get started now. If you’re owed money and the usual channels aren’t working, it’s worth taking the next step. The sooner you act, the sooner you can move forward.
