Work Health & Safety Legislation Changes You Need to Know in 2026

Work health and safety legislation in Australia has seen its biggest overhaul in years across 2025–2026. The WHS changes in 2026 span three major fronts: psychosocial hazard obligations are now enforceable in every state; NSW has passed landmark laws making AI and digital work systems an explicit WHS duty; and Codes of Practice are becoming mandatory compliance benchmarks rather than optional guidance. If you run a business anywhere in Australia, whether in Melbourne, Sydney, or Brisbane, here’s what the new health and safety legislation means for you.

A note before we dive in: WHS legislation isn’t Future Advisory’s core area of expertise, we’re your tax and accounting team, not your WHS consultants. But these changes directly affect the businesses we work with, and we think you need to know about them. We’ve pulled together the key updates here to help you ask the right questions. For specific WHS compliance advice, speak to a qualified WHS consultant or employment lawyer in your state. We can point you in the right direction if you need one. 

What does it mean in a nutshell?

• Psychological health is treated the same as physical safety
• Regulators expect active prevention, not just policies
• Directors and senior leaders have personal due-diligence obligations
• Penalties for getting this wrong can be very serious

Here’s what you need to know, in more detail.

What are the main WHS changes in 2026?

The main work health and safety legislation changes in 2026 include:

1. Psychosocial hazards are now a regulated, enforceable obligation in every Australian jurisdiction.
2. NSW passed the Work Health and Safety Amendment (Digital Work Systems) Act 2026, making AI and algorithmic work allocation an explicit WHS duty.
3. Codes of Practice in NSW become mandatory compliance benchmarks from 1 July 2026 (not just guidance).
4. Unions can now initiate civil penalty proceedings for WHS breaches in NSW (from 1 March 2026).
5. Australia will replace Workplace Exposure Standards with Workplace Exposure Limits from 1 December 2026.

1. Psychosocial Hazards: Now Explicitly Regulated Under WHS Legislation

Under the updated laws, businesses must identify, assess and control psychosocial hazards, such as:

• Excessive workload or unrealistic deadlines
• Bullying, harassment or sexual harassment
• Poor role clarity or poor management support
• Remote or isolated work
• Exposure to traumatic events
• Poorly managed organisational change

If a risk exists, it must be managed using the same approach applied to physical hazards (job design, staffing, systems, not just training).

2. Codes of Practice: From Guidance to Compliance Benchmark (NSW: 1 July 2026)

Most jurisdictions now have an approved Code of Practice on psychosocial hazards, which differ state-to-state. While not legislation, these codes:

• Set out what regulators consider “reasonably practicable”
• Can be relied on by inspectors and courts
• Make it much harder to argue you “didn’t know” what was required

Victoria’s new Psychological Health Regulations and Compliance Code started on 1st December 2025. Find the full document here – we suggest having a read! 

NSW update (1 July 2026): From 1 July 2026, NSW PCBUs must comply with approved Codes of Practice, or demonstrate they are managing hazards to an equivalent or higher standard. This is a material shift from the previous “guidance only” status. In practice, it means departing from a Code requires documented evidence, not just good intentions. This is already in effect in other jurisdictions and now extends to NSW.

3. Director Due Diligence Obligations Under WHS Legislation

If you’re a director, business owner, or senior leader, you have a legal duty to exercise due diligence (again, differing according to your state), which includes:

• Keeping up to date with psychosocial WHS obligations
• Understanding psychosocial risks in your business
• Ensuring systems, resources, training and reporting are in place
• Verifying those systems are actually working

Failure can lead to personal prosecution, separate from the company. So… scroll back up and click on that link to the full code outline if you skipped it the first time.

4. WHS Penalty Levels in Australia (2026)

Because psychosocial risks are now clearly WHS risks, breaches attract the same penalties as physical safety breaches:

Note: Exact amounts vary by jurisdiction. NSW figures reflect 2025–26 indexed amounts.

5. Why Regulators Are Cracking Down: The Claims Data (2025–26)

Why the crackdown?

Safe Work Australia reports mental health conditions now account for about 12% of serious claims and the median time lost is around five times other injuries.

• Psychological injury claims are rising fast
• They last much longer than physical injuries
• They cost far more per claim
• They are putting serious pressure on workers’ compensation schemes

This is driving:

• More inspections
• More improvement notices
• Greater willingness to prosecute
• Less tolerance for “policy-only” approaches

Safe Work Australia’s Operational Plan 2025–26 confirms psychological health remains a priority enforcement area. Combined with the expansion of who can bring civil penalty proceedings (including unions in NSW from 1 March 2026), businesses face more enforcement vectors than at any point previously.

6. AI and Digital Work Systems Are Now an Explicit WHS Risk (NSW)

This one’s brand new, and if you use any form of automated scheduling, task allocation software, performance-tracking tools, or AI-driven workflows in NSW, it directly affects you.

In February 2026, NSW Parliament passed the Work Health and Safety Amendment (Digital Work Systems) Act 2026. For the first time in Australian WHS law, AI and digital work systems are explicitly regulated as workplace hazards. Here’s what changed:

• Your duty of care now expressly includes ensuring workers’ health and safety is not put at risk by the use of a “digital work system”, defined broadly as an algorithm, artificial intelligence, automation, or online platform.
• A specific new duty (s.21A) requires PCBUs to ensure that the allocation of work by digital systems doesn’t put workers at risk, this directly captures automated rostering, gig economy platforms, and AI scheduling tools.
• Union permit holders now have the right to enter your workplace and inspect digital work systems where a WHS breach is suspected.

Importantly, you remain legally responsible for risks created by third-party software, even if you didn’t design it. If an algorithm dishes out impossible workloads, that’s your problem to fix, not just the vendor’s.

The practical risks regulators are watching for include: excessive workloads imposed by algorithms, constant performance monitoring creating psychological pressure, and discriminatory decision-making from biased AI systems.

The commencement date hasn’t yet been proclaimed by the NSW Government, but businesses should start auditing their digital systems now. Think of it like knowing a council inspection is coming, better to find the issues yourself first.

This is the first law of its kind in Australia. Whether other states follow is still being watched, but given NSW typically leads on WHS reform, it’s unlikely to stay local for long.

7. Workplace Exposure Limits Replace Exposure Standards From December 2026

One more significant WHS change coming before the end of 2026 that affects businesses in industrial, construction, and manufacturing sectors: from 1 December 2026, Australia will replace Workplace Exposure Standards (WES) with Workplace Exposure Limits (WEL).

These limits apply to airborne contaminants, dusts, fumes, vapours, gases, and similar, and the new WEL framework sets clearer, more protective national benchmarks. If your business involves any exposure to airborne substances, you’ll need to:

• Review current ventilation and PPE arrangements against the new WEL thresholds
• Update exposure monitoring programs to reflect the new limits
• Revise safe work procedures before December 2026

For most office-based or service businesses, this one won’t hit you directly. But if you work in trades, construction, manufacturing, or any environment with chemical or dust exposure, flag this date now, it’s a compliance deadline, not a guideline.

Work Health and Safety legislation NSW – what’s changed in 2026

If you’re running a business in New South Wales, 2026 brings a stack of specific work health and safety legislation changes that go beyond the national picture. Here’s the NSW-specific summary:

Codes of Practice Become Mandatory (1 July 2026)

From 1 July 2026, approved Codes of Practice in NSW are no longer just guidance, PCBUs must follow them or demonstrate they’re managing the relevant hazards to an equal or higher standard. This significantly raises the bar in WHS investigations and prosecutions. If a SafeWork inspector arrives and your approach departs from the Code, the burden of proof shifts to you to justify why.

Unions Can Now Bring Civil Penalty Proceedings (1 March 2026)

Since 1 March 2026, registered industrial organisations, including unions, can initiate civil penalty proceedings for WHS contraventions on behalf of affected workers. Historically, this was almost exclusively a regulator’s role. The practical effect is that businesses now face a much wider pool of parties who can trigger enforcement action, including in circumstances involving psychosocial hazards or inadequate risk controls.

Silica Worker Register and Audiometric Testing

NSW also introduced a Silica Worker Register (from 1 October 2025) for all high-risk silica work, and mandatory audiometric testing from 1 January 2026 for workers exposed to hazardous noise, required at three months commencement and every two years after.

AI and Digital Work Systems Duty (Nsw-specific)

Covered in detail above, but as a NSW summary: any use of AI, automation, or algorithmic tools to allocate or monitor work is now an explicit WHS risk that requires active assessment and management.

Workplace health and safety legislation QLD – 2026 updates

Queensland has its own WHS changes rolling through 2026, and if you’re based in Brisbane or operating across Queensland, these are the ones to put on your radar.

High-risk Construction Work Redefined

From 1 July 2026, South Australia aligned with the national approach, and QLD is watching similar movement. Under Work Health and Safety (High-Risk Plant) Amendment Regulation 2026, WorkSafe QLD updated plant safety requirements, with particular attention to inspections, registration, and operator competency for high-risk plant equipment.

Psychosocial Regulations Fully in Force

Like all other states, Queensland now has enforceable psychosocial hazard regulations under the national model WHS framework. PCBUs must identify, assess, and control psychosocial risks, and Queensland’s regulator, WorkSafe QLD, has signalled active enforcement rather than an education-only approach.

The obligations are the same as in other states: workload, role clarity, support, bullying, and isolated work must all be managed as genuine WHS risks. If you haven’t updated your WHS risk register to explicitly include psychosocial hazards, that’s the first thing to fix.

What Should Business Owners Do Now?

Here’s an updated, non-negotiable list, expanded to cover the 2026 changes:

• Psychosocial hazards: Treat them like physical risks, document, assess, control. If your risk register doesn’t list them explicitly, fix that this week.
• Review Codes of Practice for your state: In NSW from July 2026, Codes are mandatory benchmarks. In Victoria, the Psychological Health Compliance Code is already active. Read the one for your jurisdiction.
• Audit your digital work systems (especially in NSW): If you use AI scheduling, performance tracking, automated rostering, or algorithmic task allocation, run a risk assessment on those systems now, before the NSW Act’s commencement date is announced.
• Prepare for expanded union oversight (NSW): Since 1 March 2026, unions can initiate WHS civil penalty proceedings. Get your documentation, consultation records, and risk registers in order.
• Train your managers, not just your workers: Poor management is still one of the biggest psychosocial risk drivers. Manager training on workload, feedback, and clear role design is a legal control, not a nice-to-have.
• Ensure director-level reporting is in place: If you’re a director, you need regular WHS reporting on psychosocial risks, not just a policy on paper.
• Industrial/trades businesses: Check the Workplace Exposure Limits (WEL) changes coming 1 December 2026 and assess your ventilation, PPE, and monitoring programs now.
• Don’t rely on EAPs alone: Regulators expect structural prevention, job design, workload management, staffing, not just support after harm occurs.
