Product Overview

Summary: This Contractor and Subcontractor Management Safe Operating Procedure provides a clear, end‑to‑end framework for engaging, onboarding, supervising and reviewing contractors in line with Australian WHS laws. It helps PCBU’s demonstrate due diligence, control on-site risks, and ensure that every contractor and subcontractor works to your safety standards—not just their own.

Engaging contractors and subcontractors does not transfer your WHS obligations. Under Australian WHS legislation, the primary duty of care remains with the person conducting a business or undertaking (PCBU). This Contractor and Subcontractor Management SOP gives you a structured, defensible process for selecting, inducting, coordinating and monitoring external workers so that their activities do not introduce uncontrolled risks to your people, your site or your reputation.

The procedure walks through each stage of the contractor lifecycle—from pre-qualification and verification of insurances and licences, through to WHS documentation review, site-specific inductions, permit-to-work requirements, supervision, consultation, and post-job performance review. It addresses common pain points such as inconsistent inductions, poor communication between multiple contractors, and uncertainty about who is responsible for what on shared worksites. By implementing this SOP, organisations create a consistent, auditable approach that supports compliance with WHS laws, reduces the likelihood of incidents involving contractors, and gives senior leaders confidence that contractor activities are being managed to the same standard as internal operations.
