Where Did Australia’s Psychosocial Laws Come From?

The short version: they grew out of a national review of our work health and safety laws, against a backdrop of psychological injury claims that were becoming longer and more expensive. The psychosocial laws ask employers to manage the parts of work that can harm people mentally, the same way we’ve long managed the parts that can harm them physically.

I’ve been speaking with a few HR professionals lately. Smart, experienced people. And a lot of them are still a little puzzled by these rules. That’s worth paying attention to, because if the people responsible for rolling them out find them murky, the intent behind them has probably been lost somewhere along the way.

So here’s where the psychosocial laws actually came from, and why I think the message got muddled.

What are the psychosocial laws?

“Psychosocial laws” is shorthand for the work health and safety duty to manage psychosocial hazards. Those are the aspects of work that can cause psychological harm: things like low control over the job, poor support, unclear roles, inadequate reward and recognition, and demands that never let up. (the full list of hazards is here)

The duty asks employers to identify those hazards and manage the risks so far as is reasonably practicable. The primary duty generally sits with the PCBU or employer, and officers and workers have duties too, which is part of why it’s worth understanding properly rather than fearing.

There isn’t one single set of psychosocial laws, either. Each state and territory puts the model regulations in place its own way, and Victoria runs its own OHS system, with specific Psychological Health Regulations that commenced on 1 December 2025. The exact rules vary, and the underlying direction is broadly the same.

Where did the psychosocial laws come from?

Mostly, it came out of a review. A national review of the model WHS laws, handed to ministers in late 2018 and led by independent reviewer Marie Boland, found that psychological health wasn’t being treated as seriously as physical safety. Its Recommendation 2 led directly to new model regulations on psychosocial risk. (Safe Work Australia)

What strengthened the case was the state of the claims. Work-related mental health claims had become the costly, drawn-out ones. Safe Work Australia’s data shows they carry more than three times the median compensation and more than four times the median time off work of physical injuries and illnesses. (Safe Work Australia)

Worth being clear on one thing. WHS duties already covered psychological health, because “health” has always included the psychological kind. What changed in 2022 is that the model WHS Regulations added specific rules explaining how psychosocial risks must be identified and managed, and Safe Work Australia released a code of practice on how to do it. The states have been folding it into their own laws since.

Put simply, the system was paying a fortune to clean up psychological harm after it happened, and the rules sharpened the focus on preventing it.

Why the psychosocial laws can feel confusing

Here’s my read on why even sharp HR people find this hard to place.

HR mostly lives in policy, engagement and complaints. Someone raises an issue, a process kicks in, and responding to it well is exactly what HR is trained for. The psychosocial laws sit a step outside that. They’re a safety duty, and safety works the other way around. It doesn’t wait for a complaint. It asks you to design the work so the harm doesn’t happen in the first place.

That’s the same logic we’ve applied to machinery and working at heights for decades, now pointed at how work is organised. It’s prevention rather than response. And if your whole training is in responding, prevention can feel foreign.

The part that often gets missed

This is where it gets genuinely interesting for me.

Look at the hazards on the list. Low control. Poor support. Unclear roles. Inadequate reward and recognition. Relentless demands.

Those aren’t only wellbeing risks. They’re the exact conditions decades of workplace research link to lower performance. The same things that make work psychologically safer are the things that help people do good work. Manage them well and you don’t just lower your risk, you get a better-run team. (more on how the hazards line up with performance)

So culture, psychosocial risk and performance aren’t three separate problems. They’re usually different readings of the same conditions.

If you want to see which of those conditions are helping your team and which are quietly working against them, our Team Culture Diagnostic is built to surface exactly that.

The message that got lost

Which brings me to the real problem.

The central policy aim was prevention: identifying and controlling the conditions that create psychological harm before people are injured. And those conditions happen to be the same ones that drive performance. In that sense, the rules handed businesses a blueprint.

And somewhere between the policy and the rollout, wrapped in fines and obligations and compliance language, that message got lost. It started sounding like one more thing to be scared of, instead of the clearest list anyone has produced of what actually makes a workplace work.

The way it’s being enforced may not be perfect. The thinking underneath it is sound.

A better way to read the list

So if you’re an employer looking at the psychosocial laws and feeling the dread, try reading the list differently.

It isn’t a compliance checklist someone’s using to catch you out. It’s a fairly accurate description of the conditions that either help your people perform or slowly wear them down.

Meet the intent and the compliance tends to follow. Chase the compliance alone and you’ll tick boxes while the actual conditions stay exactly as they were.

That’s the reframe I think this whole conversation needs.

Frequently asked questions

Where did Australia’s psychosocial laws come from?

They came out of a 2018 national review of the model WHS laws, which recommended dealing with psychological health directly, with rising and long-running mental health claims strengthening the case. WHS duties already covered psychological health; what changed in 2022 is that the model WHS Regulations added specific rules on how psychosocial risks must be managed.

When did the psychosocial laws start in Australia?

The model WHS Regulations were amended in 2022 and Safe Work Australia released its code of practice that year. States and territories have been adopting the changes into their own laws since then, on slightly different timelines.

Are the psychosocial laws just about compliance?

Not really. They target the same work conditions that decades of research link to performance. Managing them is a legal duty, and it’s also good management. The compliance and the performance point in the same direction.

Want help turning the list into something useful?

The psychosocial laws describe the conditions. They don’t tell you what yours look like right now. Base State helps organisations see the conditions driving how their people work, and build practical systems that lower risk and lift performance at the same time. Get in touch and we’ll take a look.
