Security of Payment Act NSW — Your Rights as a Subcontractor

New South Wales was actually the first Australian state to enact Security of Payment legislation, passing the Building and Construction Industry Security of Payment Act 1999. More than 25 years later, it remains one of the strongest protections for subcontractors in the country.

Here’s what NSW subcontractors need to know.

Who Is Covered in NSW?

The NSW SOP Act covers anyone who has carried out construction work or supplied related goods and services under a construction contract. Construction work includes building, maintenance, repair, demolition, civil engineering and associated professional services.

Reference Dates in NSW

In NSW, the reference date is determined by your contract. If your contract specifies a date for making progress payment claims, that is your reference date. If no date is specified, the reference date is the last day of each month.

The Payment Claim Requirements

Under the NSW Act, a valid payment claim must:

  • Be in writing
  • Identify the construction work or goods and services
  • State the amount claimed
  • State that it is made under the Building and Construction Industry Security of Payment Act 1999

The 10-Day Response Window

The respondent (head contractor) has 10 business days to respond with a payment schedule. Failure to respond means the entire claimed amount is due as a debt — and the claimant can proceed directly to enforcement without adjudication if they choose.

Adjudication in NSW

If the amount is disputed, you can apply to an Authorised Nominating Authority (ANA) for adjudication. NSW has several ANAs including the NSW Fair Trading adjudication registry. The adjudicator must determine the application within 10 business days of receiving the adjudication response.

Why NSW Subcontractors Leave Money on the Table

Despite the strength of the NSW Act, most subcontractors never use it. The reasons are familiar: cost of legal help, fear of damaging the relationship, and not knowing the process. PayClaim solves all three — automated, affordable, and straightforward.
