Does a subcontractor agreement have to be in writing in Australia?

A verbal subcontract can be legally binding, but a written agreement is strongly recommended. It records the agreed scope, price and payment terms, which is exactly the evidence you need if a payment dispute later goes to adjudication under Security of Payment legislation or to court. Most disputes between contractors and subcontractors come down to what was — or was not — agreed in writing.

What should a subcontractor agreement include?

At a minimum: the parties and their ABNs, a clear scope of works, the site address, the contract price, payment terms (including progress claim cycle and payment days), retention amount if any, the defects liability period, insurance requirements, and a dispute resolution clause. This generator builds all of these into a single document.

Is this subcontractor agreement template free?

Yes. The generator is free with no sign-up. You enter the job details, generate the agreement, and print or save it as a PDF. It is a general template for Australian construction work and is not a substitute for legal advice on a specific high-value or complex contract.

What happens if the subcontractor isn't paid under the agreement?

A clear written agreement makes recovery far easier. If a progress claim or final invoice goes unpaid, the subcontractor can issue a formal letter of demand, make a payment claim under Security of Payment legislation, or escalate to adjudication. A signed agreement is the foundation for all of these steps.

This is a general template for routine Australian construction subcontracts and does not constitute legal advice. For high-value, complex or unusual contracts, have it reviewed by a solicitor.

Why a written subcontractor agreement is your best protection against not getting paid

In Australian construction, the single biggest predictor of whether a subcontractor gets paid on time is not the size of the head contractor — it is whether the terms were agreed in writing before work started. When a payment dispute arises, the first question any adjudicator, lawyer or court asks is: what did the parties actually agree? A handshake and a string of text messages rarely answer that cleanly.

Construction is consistently the worst-paying industry in the country. Our 2026 Australian Debt Collection Report documents how late and non-payment cascade down the contracting chain, and how Master Builders Australia recorded thousands of construction insolvencies in a single financial year. A clear agreement does not stop a head contractor going under — but it dramatically improves your position in the queue if they do, and it removes the "we never agreed that" defence that drags out routine disputes.

What this generator builds in

Defined scope & site — so variation claims later have a baseline to measure against.
Price & payment terms — contract sum, progress claim cycle and the number of days to pay, which set the clock for Security of Payment rights.
Retention & defects liability — the two clauses most often used to withhold money from subcontractors.
Dispute resolution — a clear escalation path before anyone reaches for lawyers.
