Getting paid for work you’ve already done shouldn’t require a fight — but in construction it too often does. That’s exactly why security of payment laws exist. Every Australian state and territory has legislation designed to help contractors, subcontractors and suppliers recover money owed under a construction contract, through a fast, independent process that sidesteps expensive court battles. With significant reforms landing across the country in 2026 — including a new construction trust scheme in Western Australia and major changes in Victoria — understanding your rights has never been more worthwhile.
This guide explains what security of payment means, how the process works, what’s changing in 2026, and the mistakes to avoid — written in plain terms for Australian builders, subcontractors and suppliers. It’s general information, not legal advice, and the rules differ significantly by state.
WHAT IS SECURITY OF PAYMENT?
Security of payment refers to the laws in each Australian state and territory that give people in the construction industry a statutory right to be paid for work they’ve done, and a quick way to enforce it. The whole point is to keep cash flowing down the contracting chain rather than leaving subcontractors waiting or fighting for money.
The core idea is a legal right to progress payments backed by a fast dispute process called adjudication. Security of payment exists because, without it, those lower down the chain had little practical power to recover what they were owed.
WHY IT MATTERS SO MUCH
Construction runs on long payment chains, thin margins and large sums, so a single non-payment can ripple downward and sink a subcontractor who did nothing wrong. Security of payment gives that subcontractor a genuine, enforceable right rather than only the option of costly litigation.
It matters even more given the industry’s financial pressures. Construction accounts for a large share of business insolvencies, and getting paid promptly is often what keeps a smaller operator solvent — which is precisely what security of payment is designed to protect.
HOW THE PROCESS WORKS
While the detail varies by state, most security of payment regimes share the same building blocks:
- Payment claim — the contractor makes a formal claim for a progress payment for work done.
- Payment schedule — the party who owes money must respond, stating what they’ll pay and why.
- Adjudication — if there’s a dispute, an independent adjudicator decides quickly, outside court.
- Enforcement — the adjudicator’s determination can be enforced, giving the decision real teeth.
The strength of security of payment lies in speed and enforceability: it’s built to deliver a fast, binding outcome so cash keeps moving rather than freezing during a long dispute.
WHAT’S CHANGING IN 2026
Security of payment is a live area of reform right now, which is exactly why it’s worth understanding this year. In Western Australia, the government is introducing a statutory construction trust scheme to replace the existing Project Bank Account model on state government projects above a set value, aiming to protect subcontractors’ money more simply and reliably if a head contractor becomes insolvent. This builds on WA’s earlier overhaul, where the Building and Construction Industry (Security of Payment) Act 2021 replaced the older Construction Contracts Act and created a statutory right to progress payments. In Victoria, substantial reforms to the security of payment regime commenced in 2026, strengthening protections for those making claims. The details differ by state and continue to change, so the practical message is to know the current rules where you work rather than assuming they’re the same everywhere or unchanged from a few years ago.
HOW TO PROTECT YOUR RIGHT TO PAYMENT
1. Know the rules in your state
Security of payment laws differ across states, so learn how yours works. The rights and timeframes that apply depend entirely on your jurisdiction.
2. Get your paperwork right
Make payment claims correctly and on time, since these regimes are strict about form and deadlines. A defective claim can lose you the protection.
3. Respond to claims properly
If you’re the one who owes money, issue a payment schedule as required. Failing to respond correctly can cost you the right to dispute later.
4. Keep good records
Document work done, claims made and approvals given. Strong records are what let you prove your position quickly if it comes to adjudication.
5. Act fast on disputes
These processes run on short timeframes, so don’t delay if a payment issue arises. Missing a deadline can forfeit a valuable right.
WHY PAPERWORK WINS OR LOSES THESE CASES
Security of payment regimes are powerful, but they are unforgiving about process. Because the whole system is built for speed, it runs on strict deadlines and specific requirements for how claims and responses must be made — and adjudicators apply those rules firmly. A subcontractor with a completely valid entitlement can still lose simply because a payment claim was late, wrongly formatted, or unsupported by records, while a well-organised operator who makes claims correctly and keeps clean documentation of work done and approved is in a strong position. The lesson is that security of payment rewards good administrative habits as much as being in the right. Getting the paperwork consistently correct isn’t bureaucracy for its own sake; it’s what turns a legal right into money actually recovered.
COMMON SECURITY OF PAYMENT MISTAKES TO AVOID
- Assuming the rules are the same everywhere. Security of payment differs by state, and getting the wrong regime wrong can cost you.
- Defective or late claims. These regimes are strict on form and timing, and errors forfeit protection.
- Not responding to a claim. Failing to issue a payment schedule can lose you the right to dispute.
- Poor records. Without documentation, a valid entitlement can be impossible to prove quickly.

The law varies by state and changes over time, so get advice for your jurisdiction and current rules.
FREQUENTLY ASKED QUESTIONS
What is security of payment?
Security of payment refers to the laws in each Australian state and territory that give construction contractors, subcontractors and suppliers a statutory right to be paid for work done, and a fast, independent process called adjudication to enforce it without going to court.
How does the security of payment process work?
Generally a contractor makes a formal payment claim, the party who owes money responds with a payment schedule stating what they’ll pay and why, and if there’s a dispute an independent adjudicator decides quickly. The determination can then be enforced.
What’s changing with security of payment in 2026?
Western Australia is introducing a statutory construction trust scheme to replace Project Bank Accounts on larger state government projects, and Victoria has commenced substantial reforms strengthening claimants’ protections. The rules differ by state and keep changing, so check what currently applies where you work.
What happens if I make a late or defective claim?
You can lose the protection. Security of payment regimes are strict about the form and timing of claims and responses, and adjudicators apply those rules firmly, so even a valid entitlement can fail on a technicality. Correct, timely paperwork is essential.
CONCLUSION
Security of payment gives construction businesses a real, enforceable right to be paid, backed by a fast adjudication process rather than costly litigation. Know the rules in your state, get your claims right and on time, respond to claims properly, keep good records, and act fast on disputes.
With major security of payment reforms landing in 2026, understanding your rights and keeping disciplined paperwork is what turns the law’s protection into cash actually recovered. As the rules vary by state and change over time, get advice for your jurisdiction.
