Who must comply with PCBU primary duty of care (TAS WHS Act s 19)?
The applicability test for PCBU primary duty of care (TAS WHS Act s 19) (WorkSafe Tas), 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
Tasmania PCBUs must, so far as is reasonably practicable, ensure the health and safety of workers and others affected by the work.
Section 19 of the Work Health and Safety Act 2012 (Tas) imposes the primary duty of care on every person conducting a business or undertaking (PCBU) in Tasmania: so far as is reasonably practicable, a safe work environment, safe plant and structures, safe systems of work, safe use and storage of substances, adequate facilities, information, training and supervision, and monitoring of workers' health and workplace conditions. "Health" includes psychological health. Officers must exercise due diligence (s 27). The Work Health and Safety Act 2012 (Tas) follows the model WHS Act, so the duty is the same as in the other model-law jurisdictions; the penalties and the industrial manslaughter offence are set locally. Tasmania's version carries the Category 1 to 3 offences in sections 31 to 33 with fixed dollar maximums written into the Act, and since 2 October 2024 a separate industrial manslaughter offence (s 29C, inserted by Act No. 15 of 2024). Incident duties sit in Part 3: section 38 requires the PCBU to ensure the Tasmanian regulator is told immediately after it becomes aware of a notifiable incident, by telephone or in writing and by the fastest possible means, and section 39 requires whoever manages or controls the workplace to leave the incident site undisturbed until an inspector arrives or directs otherwise.
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 PCBU operating in Tasmania, including sole traders and businesses with no employees, plus officers and workers. In Tasmania the notification duty (s 38) falls on the PCBU, and the site-preservation duty (s 39) on the person with management or control of the workplace.
What triggers it: Conducting a business or undertaking in the jurisdiction (whether or not you employ anyone).
Jurisdiction: Tasmania law only. A business with no operations in TAS is outside it, whatever the rest of the test says.
Which industries are in or out
Outcome across the 35 industries Rules Mate maps (35 of 35: yes).
The answer is the same in every industry: yes. Industry does not change who must comply.
Business structure and size
Structure does not change the answer across all industries: for every structure the answer is "yes".
Size does not change the answer across all industries: at every size band the answer is "yes".

- Frequency
- Ongoing
- Evidence to keep
- WHS risk register and control plan (including psychosocial hazards); safe work procedures; induction, training and supervision records; consultation records with workers; incident and hazard reports; officer due-diligence records (board WHS reporting). Record of each notifiable incident, kept for at least 5 years from the day notice was given (s 38(7)).

A death caused by a reckless or negligent breach is separately punishable as industrial manslaughter (see industrial-manslaughter-tas). Under the Tasmanian Act an individual convicted of a Category 1 offence also faces up to 5 years' imprisonment (s 31). Category 2: up to $1,500,000 (body corporate), $300,000 (PCBU or officer) or $150,000 (other individual); Category 3: up to $500,000, $100,000 or $50,000 (ss 32-33).
