What Are Hazardous Manual Tasks (Manual Handling) Under Australian WHS Law?

Most business owners think manual handling is a tradies problem. You picture warehouses, construction sites, people moving heavy things. But if that's your mental model of the risk, you're probably missing the injuries happening right in front of you.
Under the WHS Regulations, "hazardous manual tasks" (often called manual handling) are defined much more broadly than most people expect. And the obligations that come with managing them apply across Australian businesses in every industry..
Here's what you actually need to know.
What the law actually requires
In every state and territory except Victoria, the model WHS laws require every person conducting a business or undertaking (PCBU) to manage risks to workers from hazardous manual tasks. Victoria operates under its own OHS Act 2004, with similar duties for hazardous manual handling. This duty sits under the general duty to provide a safe workplace, with the Regulations adding more specific obligations on top.
In plain English, this means:
You must identify hazardous manual handling tasks in your workplace
You must assess the risks those tasks create
You must implement controls to eliminate or minimise those risks, so far as is reasonably practicable
You must review your controls, and you should keep records of how risks were identified, assessed and controlled
"So far as is reasonably practicable" matters here. It's not a get-out clause. It means you're expected to do everything that's reasonable to reduce the risk, taking into account the likelihood of harm, the severity of potential injury, your knowledge of the hazard, and the cost and feasibility of controls.
Under the model WHS Act, a Category 2 breach (where a duty failure exposes a person to risk of death or serious injury or illness) can attract penalties of up to $2.373 million for a body corporate and $475,000 for an individual PCBU or officer (as at 1 July 2025). Category 1 breaches involving reckless conduct carry higher penalties again.
What "hazardous manual tasks" actually means
This is where a lot of businesses get caught out. Under the model WHS Regulations, a hazardous manual task is any task that requires a person to lift, lower, push, pull, carry, move, hold or restrain a person, animal or thing, and that involves one or more of these risk factors:
Repetitive movement
Repetitive or sustained force
High or sudden force
Sustained or awkward postures
Exposure to vibration
Notice what's not on that list? A weight limit. "Hazardous manual tasks" don't start at 20 kilograms. It starts when a task creates a meaningful risk of musculoskeletal injury, regardless of how much an item weighs.
That means:
A commercial cleaner mopping floors for three hours can be performing a hazardous manual task
An office worker using a poorly positioned mouse all day can be performing a hazardous manual task
A hairdresser working on clients for six hours with arms raised can be performing a hazardous manual task
A tradie working in an awkward space for an extended period can be performing a hazardous manual task
This is not a high-risk-industry-only obligation. It's a universal one.
The numbers behind the obligation
Manual handling injuries are the most common type of workplace injury in Australia. According to the ABS Work-related Injuries Survey 2021–22, lifting, pushing, pulling or bending was the most common cause of work-related injury or illness, at 24.1%.
When a musculoskeletal injury occurs, the median time off work is 7.4 weeks. That's a worker out of action for nearly two months, plus the associated workers' compensation costs, lost productivity, and potential regulator attention.
For small businesses, a single serious manual handling injury can be genuinely disruptive. And in most cases, these injuries are predictable and preventable with the right controls in place.
The objection worth addressing: "We train workers to lift correctly"
Manual handling training is valuable. Correct technique reduces risk. But here's the thing: training workers how to lift is a lower-order control, and relying on it as your primary risk management strategy doesn't meet your WHS obligation.
The hierarchy of controls applies to manual handling, just like any other hazard:
1. Eliminate the need for the task altogether (redesign the work)
2. Substitute a less hazardous task or approach
3. Isolate the hazard
4. Use engineering controls (mechanical aids, adjustable workstations, trolleys, hoists)
5. Use administrative controls (job rotation, rest breaks, scheduling)
6. Personal protective equipment (last resort only)
Training sits under administrative controls. It should be part of your approach, not the whole approach. If the only control you've implemented for a high-repetition manual task is a training session on how to lift properly, you have a gap worth closing.
What you should have in place
There are three practical steps that every business should work through:
Identify your hazardous manual tasks. Walk through your workplace and map out the tasks that involve repetitive movement, sustained posture, high force, or vibration. For each one, ask whether there's a meaningful risk of musculoskeletal injury. Don't just look at the heaviest tasks. Look at what workers are doing repeatedly, for how long, and in what positions.
Assess and control the risk. For the tasks you've identified, work through the hierarchy of controls. Can the task be redesigned? Can equipment reduce the manual component? Can rest breaks or job rotation reduce exposure? Document what you've assessed and what controls you've implemented.
Document a manual handling procedure and risk assessments. Verbal instructions don't constitute a procedure. Under the WHS Act, if an inspector visits or an incident occurs, you need to be able to show what you identified, what you assessed, and what controls you put in place. A documented hazardous manual tasks procedure, with task-specific risk assessments, is the record of that work. Review your procedure at least annually, or whenever work changes significantly.
How this connects to your WHS Manual
A standalone manual handling procedure is better than nothing. But it works best as part of a broader WHS Management System.
Your WHS Manual provides the framework: the policy, the responsibilities, the risk management process. Your hazardous manual tasks procedure then sits within that framework, backed by task-specific risk assessments and records of worker inductions and training.
If your business doesn't have a WHS Manual, or if the one you have is years out of date, the manual handling procedure is probably just one of many gaps. The right starting point is usually a documented system that covers all of your obligations in one place, built on a foundation that's aligned to Australian regulations.
