Industrial Manslaughter Under the WHS Act 2011 (NSW)

What it is

Section 34C of the Work Health and Safety Act 2011 (NSW) is the New South Wales industrial manslaughter offence. It applies where a PCBU or senior officer engages in conduct that constitutes a failure to comply with a health and safety duty and that conduct causes the death of a worker or another person.

The section 34C offence was inserted by 2024 amendments and carries the highest penalties in Australia. It sits alongside category 1-3 offences and can be prosecuted for the same underlying facts.

The elements

Section 34C(1) requires the prosecution to prove:

• the accused is a PCBU or a senior officer of a PCBU
• the accused engaged in conduct constituting a failure to comply with a health and safety duty imposed by the WHS Act
• the conduct caused the death of another person (worker or non-worker)
• the accused's conduct was negligent, or reckless as to causing the death

The "senior officer" definition captures directors, secretaries, and executive officers of body corporates. Site supervisors and middle management typically do not meet the senior officer threshold unless they exercise senior-officer-level control.

Conduct causing death

Causation follows the ordinary criminal law approach: the conduct must be a substantial and operating cause of the death. Intervening acts that break the causal chain (unforeseen third-party conduct, deliberate self-harm by the deceased) may defeat causation.

Most construction industry industrial manslaughter prosecutions have involved falls, crush injuries, and electrocutions where the PCBU or senior officer failed to implement a control that would have prevented the death.

Penalties (highest in Australia)

Section 34C penalties:

• individual: up to 25 years imprisonment and up to $2,000,000 fine
• body corporate: up to $20,000,000 fine

Those penalties are the highest for industrial manslaughter in Australia. Queensland caps corporate at $20 million (after 2024 amendments). Victoria's workplace manslaughter caps corporate at approximately $19.8 million. WA caps at $10 million. SA, TAS at $18 million each.

No sentencing discount for early plea

The 2024 amendments introducing section 34C provided that no sentencing discount applies for an early plea of guilty. That is unusual in criminal law and reflects the seriousness with which industrial manslaughter is treated.

Officer accountability alongside corporate liability

A body corporate and its senior officers can both be prosecuted for the same industrial manslaughter incident. Personal criminal liability of directors is a growing prosecution focus, and 2024-2026 has seen several NSW prosecutions of directors under section 34C.

Interaction with section 32-33 category offences

Section 34C is prosecuted concurrently with or in lieu of category 1 (section 31) or category 2 (section 32) offences depending on the evidence. Category 1 requires proof of recklessness and high risk; section 34C requires negligence or recklessness causing death. Prosecutors often bring both charges and let the court determine which is made out.

The 2024 amendments

The 2024 WHS Act amendments introduced section 34C alongside penalty increases for category 1-3 offences and enhanced officer accountability provisions. Those amendments significantly strengthened the NSW WHS enforcement framework.

How NSW compares

NSW has the highest industrial manslaughter penalties in Australia at the corporate level. Compare:

• NSW s 34C: $20m body corporate, 25 years individual
• QLD s 34C: $20m body corporate, 20 years individual
• VIC s 39G: approximately $19.8m body corporate, 25 years individual
• SA s 30A: $18m body corporate, 20 years individual
• TAS s 34C: $18m body corporate, 21 years individual
• ACT s 34C: $16.5m body corporate, 20 years individual
• NT s 34B: $15.5m body corporate, life imprisonment individual (unique)
• WA s 30A: $10m body corporate, 20 years individual (lowest)

NSW's leadership on penalties reflects its position as the largest state and the most active industrial manslaughter prosecution jurisdiction.
