When do I need a WHS management plan?

You need a WHS management plan when the work is a construction project. Under the model WHS Regulations, a construction project is construction work costing $250,000 or more (reg 292). In Victoria, which runs a separate Occupational Health and Safety regime, the equivalent threshold is $350,000 — the $250,000 figure and reg 309 do not apply in Victoria.

Who is the principal contractor?

For a construction project, there must be a principal contractor (reg 293). The principal contractor is the person conducting a business or undertaking (PCBU) that is appointed by the client to be the principal contractor, or is taken to be the principal contractor (often the person commissioning the project if no one is appointed). The principal contractor has the duty to prepare and maintain the WHS management plan.

What must a WHS management plan contain?

Reg 309(2) requires the plan to cover four areas: (a) the names, positions and WHS responsibilities of all people with specific health and safety responsibilities; (b) the arrangements for consultation, co-operation and co-ordination between PCBUs, and for managing and resolving WHS issues; (c) the site safety rules and how people at the workplace are informed of them; and (d) the arrangements for collecting, assessing, monitoring and reviewing Safe Work Method Statements.

When must the WHS management plan be ready?

The principal contractor must prepare the written WHS management plan before construction work on the project starts (reg 309). It must be kept up to date for the life of the project and made available to anyone who needs it to do their work safely.

Does Victoria have different rules?

Yes. Victoria is not a model WHS jurisdiction — it runs a separate Occupational Health and Safety regime. The construction-project threshold in Victoria is $350,000, not $250,000, and the principal contractor duties sit under Victoria's OHS Regulations rather than reg 309.
