Who must comply with PCBU primary duty of care (QLD WHS Act s 19)?

The applicability test for PCBU primary duty of care (QLD WHS Act s 19) (WHSQ), computed across 35 industries, 9 business structures and 6 size bands.

Short answer: Every business

Every business is a PCBU — the primary duty of care applies whether or not you employ anyone.

What the obligation is

QLD PCBUs must ensure health and safety so far as reasonably practicable; industrial manslaughter live since 2017.

Section 19 of the Work Health and Safety Act 2011 (Qld) requires a person conducting a business or undertaking (PCBU) to ensure, so far as is reasonably practicable, the health and safety of workers it engages or directs while they are at work, and that other people are not put at risk by the work. That includes a work environment without risks to health and safety, safe plant and structures, safe systems of work, safe use, handling and storage of plant, structures and substances, and adequate welfare facilities. In Queensland the Category 1 offence (s 31) covers conduct engaged in with negligence or recklessness that exposes a person to a risk of death or serious injury or illness, and Part 2A creates industrial manslaughter offences for a PCBU (s 34C) and for a senior officer (s 34D) whose negligent conduct causes a death. Both industrial manslaughter offences are crimes. Penalties are set in penalty units, valued at $100 for this Act under the Penalties and Sentences Act 1992 (Qld).

The applicability test

Every business is a PCBU — the primary duty of care applies whether or not you employ anyone.

How the regulator frames it: Every person conducting a business or undertaking in Queensland, for the workers it engages or directs and for other people affected by its work; officers of a PCBU, workers and other persons at the workplace have their own duties under the Act. Senior officers are personally exposed to industrial manslaughter under s 34D.

What triggers it: Conducting a business or undertaking in Queensland that engages or directs workers, or whose work could put other people at risk.

Jurisdiction: Queensland law only. A business with no operations in QLD is outside it, whatever the rest of the test says.
