In October 2017, a contractor operated truck rolled about 87km from Newman after its fatigue monitoring camera was deliberately repositioned and stopped functioning correctly. Tragically, a second driver sleeping in the sleeper bunk lost his life when the cabin caught fire after the crash.
WorkSafe WA later found the system had recorded 468 alerts between September and the day of the crash, including 465 warnings that the camera was misaligned. None of these warnings were acted on and the operator, Centurion Transport, later pleaded guilty and was fined $40,000 plus $18,996 in costs.
The key issue is not the penalty, but that Western Australia’s fatigue management laws are separate from the Heavy Vehicle National Law (HVNL). This means operators who assume HVNL rules apply in WA may end up building compliance systems that do not meet the actual legal requirements.
Western Australia manages heavy vehicle fatigue under a separate system instead of the Heavy Vehicle National Law (HVNL). This means WA operators and anyone sending trucks into the state from the east coast must follow a different set of rules. These are enforced by different regulators and come with their own penalties.
This is what changes when fatigue rules apply in WA:
How WA Fatigue Rules Differ from the HVNL
The key difference between the two systems is structural and it helps to understand this before looking at specific hour limits.
Under the HVNL, fatigue management is strictly defined and rule based. It is organised into set categories such as Standard Hours, Basic Fatigue Management (BFM) and Advanced Fatigue Management (AFM), each with fixed work and rest limits.
Drivers must record their hours in a National Driver Work Diary and enforcement is managed by the NHVR through the NHVAS accreditation system. Responsibility is also shared across the supply chain under Chain of Responsibility which covers drivers, schedulers, operators and other parties involved in transport.
WA uses a single, employer led fatigue management framework with no tiers and no NHVR system. Responsibility sits with the PCBU, which must identify fatigue risks and manage them through a written plan. A PCBU is not just an employer; it also includes any business that has control over how transport work is carried out.
Enforcement in WA is carried out by WorkSafe WA, Main Roads WA’s Heavy Vehicle Compliance Unit and WA Police. The key practical guide is the WA Code of Practice for Fatigue Management (2019). Under the WHS Act 2020, an approved code of practice can be used as evidence when assessing whether a PCBU has met its duties. This is why the Code of Practice is central to building a compliance program, not just the regulations alone.
HVNL accredited operators often assume their NHVAS documentation will meet WA requirements, but it does not. WA law requires its own fatigue management plan, trained drivers and active monitoring. Saphyroo helps operators manage fatigue compliance across both WA and HVNL jurisdictions from a single system. The WorkSafe WA fatigue page is the primary reference for understanding how fatigue obligations are applied and what compliance looks like in practice.
Understanding Work and Rest Hours in WA
The WA regulations set limits on how long commercial vehicle drivers can work and how much rest they must take.
The 17 hour elapsed time rule catches operators who think only in driving hours. A driver who starts at 5am and spends 90 minutes loading before getting on the road is already 90 minutes into their allowed time.
By the time they reach Meekatharra, their required break is due and whether the roadhouse is open becomes more important than the schedule set in Perth.
What Counts as Work Time in Fatigue Compliance
This is one of the most commonly misunderstood areas in fatigue compliance and it is where operators consistently undercount what actually counts as work.
WA Work Time Definition
Work time includes all activities connected to operating a commercial vehicle, including:
A driver’s work time starts well before they hit the road. Washing the vehicle, pre start checks and refuelling are all included. If a driver is doing anything required to run the operation, the clock is running.
This is why break rules are based on total work time, not just driving time. A 20 minute break is required after every 5 hours of work. For example, a driver who spends 3 hours loading and then 2 hours driving has already reached the 5 hour limit, so the break is due at that point.
The 27 Hour Minimum Rest Rule in Practice
The 72 hour rule is based on a rolling time window, which often catches schedulers who think in simple daily blocks.
Over any 72 hour period, a solo driver must have at least 27 hours completely off work. This rest time must include three separate 7 hour breaks. Any break shorter than 30 minutes is still counted as work time.
When you apply this to a typical Pilbara schedule across three days, the 27 hour minimum becomes harder to meet than it first appears, especially when heat, distance and remote conditions reduce the quality of available rest time.
Fatigue Risk in Two-Up Driving Operations
Two-up driving is common on long WA routes, including Perth to Port Hedland (around 1,635km), Perth to Newman (around 1,186km) and across the Eyre Highway on the Nullarbor.
This is where many operators misunderstand how the rules apply. Under the WA Code of Practice, time spent in the passenger seat or asleep in an approved sleeper berth is counted as non work time.
On paper, the compliance rules are clear. In practice, the question is whether that rest is actually effective. The Code of Practice also notes that sleeping in a moving vehicle can lead to significant sleep debt, even when legal rest requirements are being met.
For fleet managers, the key point is that two-up driving can be legally compliant if work and rest times are properly recorded. However, plans that rely mainly on rest taken in the sleeper berth are likely to be heavily scrutinised by WorkSafe WA after an incident. Rest in the bunk may qualify as legal rest, but it does not always mean proper recovery.
Record Keeping Requirements in WA
WA intrastate operations do not use the National Driver Work Diary. Instead, PCBUs must keep progressive records of each driver’s work time and non work time. Under WA requirements, “progressive” recording means information is captured during the shift or as soon as practicable after it finishes, rather than being reconstructed later from memory.
There is no set diary format for intrastate WA operations. The PCBU can choose the system, as long as it meets the record requirements in the Code of Practice. Records must clearly show when work starts and finishes, when rest breaks are taken and what work was done.
Many WA fleets that also run into eastern states already use an electronic work diary for interstate trips and then add a WA compliant log in the same system for intrastate work.
The Code of Practice also requires a written Fatigue Management Plan that covers risk identification, control measures, driver training and review processes. WorkSafe provides free online training for drivers and administrators. While that free online training does not meet the full legal obligation, it is a useful starting point for understanding the requirements.
When a National Driver Work Diary Is Required
WA drivers only need a National Driver Work Diary when they leave WA and enter HVNL jurisdictions. It applies to heavy vehicles over 12 tonnes GVM and buses designed to carry more than 12 adults, including the driver.
Drivers can get a National Driver Work Diary through the Department of Transport WA. It must be used when operating under HVNL fatigue management rules outside Western Australia.
For operators running regular cross border routes, such as WA to SA via the Eyre Highway or into the Northern Territory via the Victoria Highway from Kununurra, drivers need a WA compliant record system while operating in WA. They also need to understand National Driver Work Diary requirements once they enter HVNL jurisdictions.
Fatigue Rules Across Borders
Cross border operations can make fatigue compliance more complex. A truck travelling from Perth to Adelaide, for example, moves from WA fatigue laws into HVNL fatigue laws once it crosses into South Australia.
The key thing to remember is that fatigue rules are based on where the vehicle is operating. WA has its own fatigue management system, the HVNL applies across most eastern states and the Northern Territory operates under a separate framework.
For operators, this means a single journey may involve different compliance and record keeping requirements depending on where the vehicle travels.
From 1 August 2026, BFM and AFM will be replaced by Alternative Compliance Hours (ACH) under the new Heavy Vehicle Accreditation (HVA) scheme.
Operators currently accredited under BFM should review their transition requirements and confirm their timeline with the NHVR before renewal.
Crossing from WA into HVNL Jurisdictions
When leaving Western Australia and entering HVNL jurisdictions, the National Driver Work Diary must begin from at least the last major rest break before the border crossing. For a truck travelling the Eyre Highway, this is typically Norseman or Balladonia, depending on where the last 7 hour rest break was taken.
Drivers must also be operating under a selected fatigue management option, such as Standard Hours, Basic Fatigue Management (BFM) or Advanced Fatigue Management (AFM). Any existing BFM accreditation applies once the vehicle enters HVNL jurisdictions from the border onward.
Entering WA from HVNL States
When entering Western Australia from HVNL jurisdictions, WA compliant work records must cover the entire portion of the trip within WA. The HVNL work diary is not stopped or replaced at the border. Instead, both systems operate at the same time for the duration of the WA leg, with WA records applying inside the state.
Crossing into the Northern Territory
The Northern Territory has not adopted the HVNL fatigue system. Instead, it uses its own WHS based framework, while recognising WA fatigue requirements for the WA portion of cross border trips. The WA and Northern Territory border is located east of Kununurra on the Victoria Highway.
How WA and HVNL Enforcement Works
The rules being enforced depend on where the inspection takes place. Main Roads WA inspections on the Great Eastern Highway apply WA fatigue laws, while NHVR operations in South Australia enforce HVNL requirements. Both regulators can also conduct retrospective audits by reviewing records after a trip or following an incident.
The real operational challenge is maintaining records that satisfy each regulator separately. Saphyroo helps operators manage work and rest records across both WA and HVNL jurisdictions from a single system, reducing the risk of compliance gaps and audit failures.
Saphyroo supports fatigue compliance across multi state operations and can help maintain visibility across both WA and HVNL requirements. Saphyroo currently supports fatigue record keeping, operational visibility and compliance evidence management, while its electronic work diary (EWD) platform progresses through the NHVR approval process.
Penalties for WA Fatigue Breaches
WA fatigue breaches are enforced under the Work Health and Safety Act 2020 (WA), rather than the penalty system used under the HVNL.
These penalties go beyond ordinary traffic offences. They are tied to breaches of workplace health and safety duties. If a fatigue related crash leads to a fatality, WorkSafe WA may investigate whether the PCBU had effective fatigue management controls and systems in place.
The Centurion case was prosecuted under the former Occupational Safety and Health Act 1984. Under the current WHS Act, Category 1 offences can carry fines of up to $3.5 million for a body corporate. Industrial manslaughter laws introduced in 2022 also allow penalties of up to $10 million for a body corporate and up to 20 years imprisonment for individuals.

The key lesson from the Centurion case remains the same regardless of which legislation applied. Simply having a fatigue monitoring system is not enough. Compliance depends on monitoring the data, identifying risks and acting on them. In the Centurion case, 468 fatigue exceptions were recorded and none were addressed.
What to Do Next
WA fatigue management comes down to three practical scenarios every operator needs to work through before deciding how to manage compliance, record keeping and cross border work.
If you only operate within Western Australia, you need a Fatigue Management Plan that meets the Code of Practice, along with driver training on WA rules. You also need progressive records that show total work time, not just driving time. WorkSafe’s online training is a useful starting point, but the Code of Practice is the main document your plan must follow.
If you operate across the WA/SA or WA/NT border, you need HVNL accreditation (Standard Hours, BFM or AFM) for the interstate portion of the trip. Drivers must also carry a National Driver Work Diary and your record system needs to meet both WA and HVNL requirements without doubling up on paperwork.
If you supply to mine sites in WA, extra site rules apply on top of state law. Companies like BHP, Rio Tinto and FMG require their own journey plans, fitness for duty checks and crib break rules for contractors. In these cases, WA law is the minimum requirement, not the highest standard.
The Centurion case shows what WA regulators focus on, which is not whether a system exists but whether it is actually used and followed in practice.
