Last updated: 9 August 2026

If your work is high-risk construction work (HRCW), you must prepare a SWMS before it starts. The model WHS Regulations list 18 categories. Here they are, with what each one covers.

What counts as high-risk construction work?

A SWMS is required where construction work:

  1. Involves a risk of a person falling more than 2 metres
  2. Is carried out on a telecommunication tower
  3. Involves demolition of load-bearing or structural elements
  4. Involves, or is likely to involve, disturbing asbestos
  5. Involves structural alterations or repairs requiring temporary support to prevent collapse
  6. Is carried out in or near a confined space
  7. Is carried out in or near a shaft or trench deeper than 1.5m, or a tunnel
  8. Involves the use of explosives
  9. Is carried out on or near pressurised gas mains or piping
  10. Is carried out on or near chemical, fuel or refrigerant lines
  11. Is carried out on or near energised electrical installations or services
  12. Is carried out in an area that may have a contaminated or flammable atmosphere
  13. Involves tilt-up or precast concrete
