What Is a WHS Management Plan and How It Differs from a WHS Management System
A WHS management plan is a project-specific document required by Regulation 309 of the WHS Regulation 2025 for construction projects valued at $250,000 or more. It is fundamentally different from a WHS management system and the two must not be confused. A WHS management system is the organisation-wide framework of policies, procedures, records, and practices through which a PCBU manages workplace health and safety across all of its operations. It is permanent, applies to the entire business, and is updated incrementally as the organisation evolves. A WHS management plan, by contrast, is a project document. It applies to a single construction project, covers a defined period from project commencement to project completion, and addresses the specific WHS arrangements for that project including the site-specific hazards, the contractors involved, the coordination arrangements, and the emergency procedures for that site. The distinction matters because the legal requirements are different, the audience is different, and the content is different. The WHS management plan is prepared by the principal contractor and must be in place before construction work commences on the project. It must be kept readily accessible at the workplace for the duration of the project. It must be reviewed and revised as necessary throughout the project as conditions change, new contractors are engaged, and new hazards are identified. When the project is complete, the WHS management plan is closed out and archived. The WHS management system, by contrast, continues in operation indefinitely. An organisation can have an excellent WHS management system and still fail to prepare an adequate WHS management plan for a specific project, or vice versa. The regulator assesses compliance with each requirement independently. Failure to prepare a WHS management plan when one is required under Regulation 309 is an offence carrying maximum penalties of $69,030 for an individual and $345,150 for a body corporate as of 2025-26 CPI indexation. This penalty applies regardless of whether the organisation has a comprehensive WHS management system in place.
When Is a WHS Management Plan Required — The $250,000 Threshold
The requirement for a WHS management plan is triggered by Regulation 309 of the WHS Regulation 2025, which applies to construction projects where the principal contractor is required to be appointed. Regulation 293 requires a person who commissions a construction project to appoint a principal contractor for the project if the cost of the construction work is $250,000 or more, or if the construction work is being carried out for a person conducting a business or undertaking and five or more persons are carrying out construction work at the same time. The $250,000 threshold is based on the total cost of the construction work, not the contract value. Construction work is defined broadly under the WHS Regulation 2025 and includes building, civil engineering, mechanical engineering, and electrical engineering work, including the construction, alteration, conversion, fitting-out, commissioning, renovation, repair, maintenance, refurbishment, demolition, decommissioning, or dismantling of a structure. It also includes any work that is preparatory to or forms an integral part of construction work, including excavation, landscaping, and site clearance. The $250,000 threshold is assessed on the total project cost, not individual contract packages. A project with a total construction cost of $300,000 that is divided into five contract packages of $60,000 each still exceeds the threshold and requires a WHS management plan. Organisations must also be aware that the threshold applies to the value of the construction work, not the total project budget. Professional fees, land costs, and equipment purchases that are not construction work are excluded from the calculation. However, all construction work costs including materials, labour, plant hire, and subcontractor costs are included. For projects that are close to the threshold, the prudent approach is to prepare a WHS management plan regardless. The administrative cost of preparing a plan that proves unnecessary is trivial compared to the penalty for failing to prepare a plan that was required. The threshold has not been indexed since it was set in the original WHS Regulation and applies uniformly across all harmonised jurisdictions.
Mandatory Content of a WHS Management Plan Under Regulation 309
Regulation 309 specifies the content that a WHS management plan must include. The principal contractor must ensure the plan addresses all of the following elements. Names, positions, and health and safety responsibilities of all persons at the workplace whose roles involve specific health and safety responsibilities. This includes the principal contractor's project manager, site manager, WHS coordinator, first aid officers, emergency wardens, and any other persons with defined WHS roles. It also includes the nominated WHS contact persons for each subcontractor. The plan must clearly identify who is responsible for what, so that any person on the project can identify the responsible person for any WHS matter. Arrangements in place, or to be implemented, for consultation, cooperation, and coordination of activities between the persons conducting businesses or undertakings at the workplace. This is one of the most important elements because it addresses the interaction risks that arise when multiple businesses work on the same site. The plan must describe how PCBUs will consult with each other about overlapping duties, how work activities will be coordinated to prevent interaction hazards, and how information about hazards and controls will be communicated between PCBUs. Arrangements for managing WHS incidents including the recording and notification of incidents, the investigation of incidents, and the requirements for preservation of incident sites for notifiable incidents. The plan must specify the incident reporting process for the project, including how contractors and their workers are to report incidents, who receives and acts on incident reports, and how the principal contractor's incident investigation process works. Any site-specific health and safety rules and the arrangements for ensuring all persons at the workplace are informed of these rules. Site rules address matters such as speed limits for vehicles, mandatory personal protective equipment requirements, hot work permit requirements, restricted access areas, and drug and alcohol testing arrangements. Arrangements for the collection and assessment, monitoring, and review of Safe Work Method Statements. The plan must describe how SWMS are submitted, reviewed, accepted or returned for revision, monitored for compliance during work execution, and reviewed when work methods change.
Practical Example — WHS Management Plan for a Commercial Fit-Out Project
A worked example illustrates how the mandatory content requirements translate into a practical WHS management plan. Consider a commercial office fit-out project in a multi-tenancy office building with a construction cost of $1.8 million, involving eight subcontractors over a 16-week programme. The WHS responsibilities section identifies the principal contractor's project manager as having overall responsibility for the implementation and maintenance of the WHS management plan. The site supervisor is responsible for day-to-day WHS management including daily pre-start briefings, inspections, and incident response. The WHS coordinator conducts weekly site inspections, reviews SWMS submissions, coordinates subcontractor inductions, and maintains the WHS management plan records. Each subcontractor nominates a safety contact person who is responsible for their workers' compliance with the plan and for communicating WHS matters between their workers and the principal contractor. The consultation arrangements describe the weekly subcontractor coordination meeting at which upcoming work activities, interaction risks, and any changes to the programme are discussed. HSR arrangements are documented, including the elected HSR's name, contact details, and the agreed arrangements for HSR access to the workplace. Issue resolution procedures describe the steps for raising and resolving WHS concerns, from direct discussion through to the involvement of the regulator. The incident management arrangements specify that all incidents, including near misses, must be reported to the site supervisor within one hour. The site supervisor assesses whether the incident is notifiable under Part 3 of the WHS Act and, if so, notifies the regulator immediately by telephone and preserves the incident site. The WHS coordinator commences the investigation within 24 hours and completes the investigation report within five business days. Site rules for the project include mandatory PPE requirements of hard hat, safety boots, high-visibility vest, and safety glasses in all work areas; hot work permits required for all welding, cutting, and grinding; no works in occupied tenancies without tenant notification and physical barriers; maximum vehicle speed of 10 km/h in the loading dock; and prohibition of working alone outside standard hours. The SWMS arrangements specify that subcontractors must submit SWMS to the WHS coordinator at least 48 hours before commencing any high-risk construction work. The WHS coordinator reviews each SWMS against a defined checklist that verifies the hazards are identified, the controls are adequate, the workers are identified and trained, and the SWMS is signed by the relevant persons.
