Subcontractor Agreement (Construction Industry Australia)

A construction subcontractor agreement is the contract between a head contractor (builder) and a subcontractor (electrician, plumber, plasterer, tiler, roofer, etc.) for a defined scope of work on a construction project. The agreement covers the scope, pricing, progress payment schedule, variations process, defects liability, retention amounts, dispute resolution, and statutory obligations under each state's Security of Payment Act.

Why this document matters

Construction subcontracting accounts for the majority of unpaid-invoice disputes in Australia. A documented subcontractor agreement is the foundation of recovery rights under both contract law and state Security of Payment legislation.

How Claim Done can help

Construction-specific subcontractor agreements have nuances (Security of Payment Act compliance, retention timing, defects liability period coordination) that are best handled by a construction-specialist lawyer for high-value projects. For straightforward sub-trade engagements, our Independent Contractor Agreement ($79) covers the core terms — scope, payment, IP, restraint, termination, and the contractor-vs-employee distinction (avoiding sham-contracting under the Fair Work Act).
