What is security of payment law in Australia?
Security of payment law is a set of state and territory laws that make construction payments move fast. They give a quick paper process for claims, replies and a short decision by an adjudicator.
What the law is for
Construction work runs on cash flow. A small business can fail while it waits for a large unpaid claim. Security of payment law was made to stop that.
Every Australian state and territory has its own security of payment law with its own name, rules and time limits. The core idea is the same in each: a claim, a reply and a fast decision.
The usual steps
- The contractor serves a payment claim on the principal or head contractor.
- The other side gives a payment schedule in reply, within the time limit.
- Any unpaid amount can go to adjudication, a fast decision by a neutral expert.
- The adjudicator decides the amount that is due.
- A court dispute can follow later, but pay now and argue later is the design.
Queensland as an example
For example, Queensland uses the Building Industry Fairness (Security of Payment) Act 2017 (BIF Act). A payment claim is usually made within 6 months of the work, or the contract time if that is shorter.
The payment schedule is due within 15 business days of the claim. An adjudication application is usually made within 30 business days of the payment schedule.
Because the rules differ by state, check the law of the place where the work is done.

Does security of payment law apply to every contract?
No. Each law has its own scope, and some contracts or work types fall outside it. Check the law for the state where the work is done.
Is a security of payment decision final?
Not always. It decides what must be paid now. A court or later process can still look at the full dispute.
