What is Security of Payment and How Does It Protect Tradies?

Security of Payment laws are some of the most important — and most misunderstood — pieces of legislation for Australian tradies and subcontractors. If you’re working in the construction industry and haven’t been paid, these laws could be your fastest route to recovering what you’re owed. Here’s what Security of Payment actually means, how it works, and how it protects you.

What Is “Security of Payment”?

Security of Payment (often abbreviated to “SOP”) refers to a set of laws in each Australian state and territory that give subcontractors, tradies, suppliers, and consultants a statutory right to receive progress payments for construction work. The laws create a fast, structured process for resolving payment disputes — without going to court and without needing expensive lawyers.

The term “security of payment” reflects the purpose of the legislation: to give people in the construction supply chain security that they will actually be paid for the work they perform.

Why Were These Laws Created?

Before Security of Payment laws existed, subcontractors had very limited options when head contractors didn’t pay. You could try to negotiate, engage a lawyer, or go to court — all slow, expensive, and often ineffective. Meanwhile, head contractors could delay, dispute, or simply refuse to pay, knowing that most small subcontractors couldn’t afford to fight them.

The result was endemic non-payment across Australia’s construction industry, costing subcontractors hundreds of millions of dollars every year and driving many small businesses into insolvency.

Security of Payment legislation changed the balance of power. Now, head contractors face strict legal obligations and tight deadlines — and subcontractors have a fast, affordable way to enforce their rights.

How Security of Payment Protects Tradies — The Core Process

The SOP process works like this:

1. Payment Claim: The subcontractor serves a formal payment claim on the head contractor or principal. This is not just a regular invoice — it’s a specific legal document that triggers statutory rights and obligations.
2. Payment Schedule: Within a set timeframe (10–15 business days depending on the state), the head contractor must respond with a payment schedule. This schedule must either confirm payment or formally dispute specific items with reasons. Failure to issue a schedule is a serious legal default.
3. Adjudication: If the head contractor disputes the claim, the subcontractor can apply for adjudication — an independent assessment by a qualified adjudicator. The adjudicator reviews both sides’ evidence and makes a binding determination, typically within 10 business days.
4. Enforcement: If the adjudicator rules in the subcontractor’s favour and the head contractor still won’t pay, the determination can be enforced as a court judgment.

Who Is Protected by Security of Payment Laws?

The laws protect:

• Subcontractors of all trades — electricians, plumbers, concreters, roofers, carpenters, plasterers, painters, tilers, and dozens more
• Building material suppliers
• Consultants and design professionals
• Labour hire providers
• Anyone performing construction work or supplying related goods and services under a contract

Importantly, the laws apply regardless of what your contract says. Even if a contract has clauses trying to limit your payment rights, those clauses are generally overridden by the Security of Payment Act.

Which Act Applies in Your State?

Each Australian state and territory has its own Security of Payment legislation:

• QLD: Building Industry Fairness (Security of Payment) Act 2017
• NSW: Building and Construction Industry Security of Payment Act 1999
• VIC: Building and Construction Industry Security of Payment Act 2002
• WA: Building and Construction Industry (Security of Payment) Act 2021
• SA: Building and Construction Industry Security of Payment Act 2009
• TAS: Building and Construction Industry Security of Payment Act 2009
• ACT: Building and Construction Industry (Security of Payment) Act 2009
• NT: Construction Contracts (Security of Payments) Act 2004

How PayClaim Makes SOP Laws Simple

The Security of Payment process is powerful, but it requires precision — payment claims must be correctly prepared and served, deadlines must be met, and adjudication applications must be properly prepared. PayClaim handles all of this for Australian subcontractors and tradies. You tell us what happened, we handle the legal process, and you get paid — typically within 10–20 business days. Flat fee, no lawyers required.
