Small Business WHS Requirements 2026: The 9 Duties That Apply to Every Australian Employer

There is no small-business exemption in Australian WHS law. From your first employee — or contractor, or labour-hire worker — nine duties apply to essentially every business:

1. Primary duty of care — physical and psychological health, so far as reasonably practicable.
2. Officer due diligence — the owner/directors' personal, non-delegable duty.
3. Consultation — real conversations with workers about safety, recorded.
4. Incident notification readiness — know what's notifiable and your regulator's number.
5. Psychosocial hazard management — enforceable duties in every state since Victoria's regulations commenced December 2025.
6. Codes of practice position — know which codes apply and your state's rule (NSW is comply-or-justify since 1 July 2026).
7. Records and training — inductions, incident register, 5-year notifiable records.
8. First aid and emergency plan — matched to your workplace by your own assessment.
9. Workers compensation insurance — compulsory in every state, separate from WHS law.

Our WHS Compliance Requirements Checker turns these into a state-correct checklist for your exact profile in about a minute — including the extra duties that switch on if you do construction work, run machinery, host contractors or have staff working from home.

Proportionality is real: a café doesn't need a mining company's safety system. What the regulator expects is the thinking, evidenced simply: a one-page risk register that names your real hazards (hot oil, knives, ladders, aggressive customers, workload spikes) with sensible controls; induction notes for each starter; an incident book; the regulator's number on the wall; and proof you asked your staff what's unsafe.

Where small businesses genuinely get hurt in enforcement: machinery without guarding, falls from height, vehicles and people mixing in yards — and increasingly, psychosocial complaints that were treated as personality clashes instead of hazards. The public prosecutions record shows the median penalty across finalised WHS prosecutions (2020–2024) sits around $40,000, with construction and manufacturing dominating the case list — and the uninsured costs (downtime, contract loss, the owner's own exposure) usually exceed the fine.

If you have nothing today, this sequence gets you defensible fastest:

• Run the WHS Quick Check (10 minutes) for your baseline, then the full requirements checklist for your state.
• Write the one-page risk register with your team — that conversation is your consultation evidence.
• Put your regulator's number where supervisors will see it, and read the notifiable incident triggers once.
• Add the psychosocial hazards honestly — workload, rosters, customer aggression — via the self-assessment.
• Check your first aid against the first aid calculator and confirm your workers comp policy is current.

That afternoon of work covers the majority of what a regulator would ask a small employer to produce — and it compounds: every later hire, contract and site inherits the system.
