On 02 Jul 26, the Industrial Court of New South Wales convicted Wumbulgal Agriculture Pty Ltd following the death of a farmhand operating a quad bike during livestock mustering.

The company was fined $555,000, ordered to pay SafeWork NSW’s agreed costs of $55,000, and required to arrange side-by-side vehicle training for all workers employed or engaged by the business. The offence was prosecuted as a Category 2 contravention of sections 19(1) and 32 of the Work Health and Safety Act 2011 (NSW). not a case involving an obscure hazard, an experimental control or an unforeseeable chain of events. The risk associated with quad bikes was well known, the necessary controls were readily available, and the business had previously received government financial assistance to purchase some of those controls.

The failure was not a lack of safety information. It was the failure to convert that information into a clear, mandatory and verified system of work.

What Happened

On 03 Feb 23, a farmhand was using a quad bike to muster sheep on one of the company’s properties. During the task, the quad bike struck an earthen mound, overturned and threw the worker from the vehicle.

The worker was not wearing a helmet. The quad bike was not fitted with an operator protective device, commonly referred to as an OPD, and the worker sustained fatal head injuries.

The Court found that it was foreseeable that a worker mustering livestock might accelerate to intercept an animal, that uneven ground could be encountered even in an otherwise flat paddock, and that a rider could be thrown from a quad bike during a rollover. It was also foreseeable that a rider without a helmet could suffer catastrophic head injuries and increase the risk of death or serious injury arising from a collision or rollover while operating a quad bike. The reasonably practicable measures identified in the proceedings included conducting and implementing an adequate risk assessment, fitting and maintaining OPDs, requiring workers to wear suitable helmets, and providing appropriate supervision, training, instruction and information.

None of those measures was particularly novel. Nobody needed to commission a research institution or await the invention of a new piece of technology.

The Business Knew About The Risk

A particularly damaging feature of the case was the company’s previous participation in the NSW Quad Bike Safety Rebate and Free Training Program.

The company had received rebates towards the purchase of a helmet, an OPD and a side-by-side vehicle. The Court found that the company did not merely have constructive knowledge of the risks, meaning it should have known about them, but had actual knowledge of the risks and the measures available to reduce them.

Despite this, helmets were recommended rather than mandated during some quad bike activities. Workers were expected to assess the conditions themselves and determine whether wearing a helmet was necessary.

An OPD purchased with rebate assistance had also been removed from one of the company’s quad bikes for operational reasons, although that was not the quad bike involved in the fatal incident. None of the company’s quad bikes had OPDs fitted when the incident occurred. It described it as remarkable that the company had received assistance to control the same risks it later allowed workers to assume. That finding should concern any business which has received regulator guidance, audit findings, improvement recommendations, consultant reports, insurance advice or internal hazard reports and then failed to implement the identified controls.

Once a risk has been specifically brought to a business’ attention, the argument that nobody understood the danger becomes rather difficult to maintain.

Worker Judgement Was Used In Place Of Risk Control

The Court identified the central failure as allowing workers to decide for themselves whether helmets were necessary.

The company’s approach assumed that an individual worker could make an adequate assessment immediately before or during the task. There was no requirement to complete or record a formal assessment, and there was no reliable system for reviewing those decisions or verifying that safe work practices were being followed.

The predictable result was inconsistent practice. Workers held different views about when helmets were required, and at least one worker told the regulator that he operated quad bikes without a helmet for a substantial proportion of the time.

This was not genuine worker empowerment. It was the transfer of a fundamental risk-control decision from the duty holder to the person exposed to the risk.

The Court made the broader point that experienced workers can become confident in their ability to manage risks, particularly where they have performed the work repeatedly without a serious incident. Familiarity with a task can make an unsafe practice feel ordinary, but it does not make the practice safe.

That is precisely why the WHS Act places the responsibility on the duty holder to identify hazards, assess risks and implement reasonably practicable controls. The primary duty cannot be discharged by telling workers to use their judgement about whether a basic life-preserving control is necessary. ies And Manuals Had Little

Operational Authority

The company had WHS, personal protective equipment and vehicle safety policies. Workers were expected to read and sign them during induction, and operator manuals were kept near the vehicles.

However, the policies did not mandate helmets for all quad bike operation. Workers were told where the manuals were located, but the manuals were not properly integrated into induction or training, and workers were not required to read them before using the vehicles.

The manufacturer’s manual required a helmet to be worn and warned of death or serious injury if its safety instructions were not followed. The company’s actual practice, however, allowed workers to decide when a helmet was necessary.

The Court observed that a worker encountering the manual would probably regard it as having little practical authority because its instructions conflicted with the employer’s accepted practices.

That is a useful test for any safety system. When the procedure, induction or manufacturer’s instruction says one thing, but supervisors and workers routinely do something else, the real system of work is the practice accepted in the field.

The document in the folder is merely the prosecution exhibit.

The Hazard Was Foreseeable On Flat Ground

The company’s approach distinguished between steep or hilly terrain, where helmet use was generally understood to be required, and lower-speed activities on relatively flat ground.

The Court rejected the adequacy of that approach. A quad bike can overturn at relatively low speed and on flat ground, particularly where surface conditions include mounds, holes, ruts, vegetation or other irregularities.

The Court found that the events leading to the fatality were foreseeable. A sheep could separate from the mob, a worker could accelerate to intercept it, uneven terrain could be encountered, the quad bike could overturn, and an unrestrained rider could be thrown and strike their head.

The worker’s actions were not shown to be outside the scope of the work or contrary to an instruction. Describing an action as unexpected after the incident did not make it unforeseeable before the incident. Distinction matters well beyond agriculture. Workers respond to changing work conditions, production demands, animals, customers, traffic, machinery faults and operational disruptions. A safe system must account for reasonably foreseeable variation in the way the work will actually unfold.

A system designed only for the ideal version of the task is not much of a system.

Rollover Protection Required Proper Assessment

The Court did not find that an OPD must be fitted in every possible quad bike operating environment. The available guidance recognised that rollover protection might be unsuitable in limited circumstances, including some heavily wooded environments where the device could introduce another risk.

That qualification does not create a general operational-convenience exemption.

The Court found that where reasonably practicable measures were available, including using side-by-side vehicles or installing OPDs, failing to adopt those measures could constitute a breach of the primary duty. In this case, permitting workers to operate quad bikes without rollover protection was part of the serious breach.

The lesson is that removing or declining a safety control requires an actual risk-based justification. “Operational reasons” is not an assessment, and convenience is not evidence that the alternative is safer.

Where a control is considered unsuitable, the business must be able to explain the operating conditions, the competing risks, the competent advice relied upon, the alternative controls implemented and how those controls are verified.

Awareness Is Not Compliance

The Court addressed an argument that substantial general deterrence was unnecessary because quad bike hazards had already been extensively publicised.

That submission was rejected. General deterrence is not limited to teaching businesses that a hazard exists. It is also intended to discourage duty holders from ignoring or failing to control risks they already understand.

The judgement observed that continued quad bike fatalities, despite decades of guidance and industry awareness, demonstrate that awareness alone is insufficient.

Safety campaigns, toolbox talks, regulator webpages and manufacturer warnings can help communicate risk. They do not replace an enforceable requirement, appropriate plant selection, competent training, supervision or verification.

A business does not control a risk merely because everyone has heard about it.

The Financial Consequences

The maximum available penalty was $1,860,843. The Court assessed an appropriate penalty of $740,000 before applying a 25 per cent reduction for the company’s guilty plea, resulting in the $555,000 fine.

The company was also ordered to pay $55,000 in prosecution costs. In addition, it must fund side-by-side vehicle training for its workers and provide SafeWork NSW with evidence that the training has been completed.

The Court took substantial mitigating factors into account, including the guilty plea, cooperation with the regulator, remorse, good corporate character, the absence of previous WHS convictions and the changes made after the incident. The business ceased using quad bikes immediately following the fatality and introduced more stringent requirements for other vehicles and activities.

Even with that mitigation, the Court regarded the contravention as highly serious and considered a substantial penalty necessary. also extends beyond the fine, legal expenses and training order. A worker died, colleagues and those connected with the business were affected, operational practices had to be changed, and the company was subjected to an investigation and prosecution lasting several years.

Reactive safety is remarkably expensive. It is also rather late.

Lessons For Officers And Managers

This case provides several practical tests that can be applied across any high-risk operation.

First, determine whether critical controls are mandatory or discretionary. Where the control prevents fatal or permanently disabling harm, leaving its use to individual preference should receive immediate scrutiny.

Second, compare written requirements with normal field practice. A manufacturer’s instruction, procedure or policy has little value where management tolerates conflicting behaviour.

Third, examine what the organisation already knows. Regulator visits, rebates, inspections, audits, previous incidents, near misses and technical advice create evidence of organisational knowledge. They also create an expectation that the knowledge will be acted upon.

Fourth, verify control implementation. Providing equipment, publishing a policy or conducting an induction does not establish that the control is being consistently applied.

Fifth, test operational explanations for removing or weakening controls. Any departure must be based on a competent assessment of the risks, supported by suitable alternative measures and formally reviewed.

Finally, do not confuse worker experience with a safety control. Experienced workers can bring valuable competence and practical knowledge, but experience does not eliminate equipment instability, gravity, kinetic energy or the consequences of an unprotected head striking the ground.

The Real Safety Jon Takeaway

This prosecution was not caused by an absence of available information. The company had guidance, policies, manuals, helmets, access to training, government assistance and knowledge of the risk.

What it did not have was a system that made the essential controls non-negotiable and verified that they were being followed.

A helmet stored in the shed is not a control. An operator manual that conflicts with accepted practice is not a control, and telling workers to decide whether they require protection is not due diligence.

Real safety begins when known risks are converted into clear decisions, properly resourced controls and evidence that those controls are working.
