What the canonical article covers

The full article at WHS duties when engaging subcontractors covers every WHS obligation that arises when a residential builder brings subbies onto a job.

Key topics:

  • Baseline PCBU duties for all jobs regardless of contract value. Engaging a subcontractor does not transfer your duty.
  • Consultation, cooperation and coordination between PCBUs under WHS Act ss 46-49. When two or more PCBUs share a duty, each must consult, cooperate and coordinate with the others.
  • Principal contractor duties for construction projects $250,000 and over, including a written WHS management plan, SWMS collection before HRCW begins, and visible site signage.
  • SWMS obligations: who prepares them, who collects them, what happens if they are missing or obviously inadequate.
  • Site-specific induction requirements for every person before they start, on top of the general white card requirement.
  • Dual status of subcontractors as both PCBU (with their own workers to protect) and a worker subject to your site rules at the same time.
  • WHS penalties indexed to July 2025 values (Category 1 to 3, body corporate and individual).
