Key takeaways
- Working at heights is defined by risk of a fall, not just height. The 2-metre rule is a trigger for higher-risk work, not a safety limit.
- Falls remain a leading cause of workplace fatalities, often occurring during short, familiar tasks where risks are underestimated.
- High-risk construction work requires proper planning, including a Safe Work Method Statement (SWMS) and clearly defined controls.
- Fall risks must be managed using the hierarchy of controls, starting with fall prevention devices before moving to positioning or arrest systems.
- Ongoing training, clear documentation, and regular refreshers help keep workers compliant, capable, and safer on site.
Understanding the working at heights requirements in Australia
Working at heights has been part of the building and maintenance industries, but it continues to present serious safety challenges. The risks of falls are often underestimated, especially during routine or short-term tasks where hazards can be overlooked. Without the right planning, even low-level work can put workers at risk.
This article explains how working at heights is regulated in Australia and what’s required to manage risks effectively. It covers common height thresholds, documentation, and the role of fall prevention devices in protecting workers. Whether you’re on site or coordinating training, understanding how to identify hazards and apply the right controls is key to reducing incidents and meeting WHS obligations.
Why working at heights safety matters in high-risk construction work
Working at heights is still one of the biggest causes of serious injuries and fatalities on Australian worksites. Roles in construction, utilities, maintenance, and local government are especially exposed, simply because working on ladders, roofs, and elevated platforms is part of the day-to-day job.
In 2024–2025, falls from height made up around 13% of work-related injury fatalities. That puts them among the most common causes of workplace deaths, alongside incidents involving moving objects at 9% and vehicle incidents at 42%. What often catches people out is that many falls don’t happen during complex or high-risk jobs, but during short, familiar tasks where the risk feels low.
Defining working at heights
Working at heights in Australia is commonly linked to the 2-metre rule, which is used as a clear trigger for higher-risk work and stricter safety requirements. Where there’s a risk of a person falling 2 metres or more, the task is classed as high-risk construction work and requires formal controls, including physical fall-prevention measures and a Safe Work Method Statement.
However, the law doesn’t stop at 2 metres. Under Work Health and Safety laws, any fall that could cause injury must be managed, even if it’s from a lower height. Falls from ladders, platforms, or into holes and excavations can still result in serious harm, which means a risk assessment and appropriate controls are required.
In practice, this means the 2-metre rule is a trigger, not a safety limit. Higher-risk work demands stronger, documented controls, while lower-height tasks still need hazards identified, risks assessed, and workers trained to manage them safely.
Looking after your employees' health and safety starts with compliance
For most roles, this starts with a Working at Heights certificate, such as RIIWHS204E – Work Safely at Heights. This course gives workers the skills to identify fall hazards, assess risk, and use fall protection systems correctly. In construction and other high-risk environments, this training is often a condition of site access.
Depending on the type of work being performed, additional training may also be required. Tasks involving scaffolding, elevated work platforms, confined spaces, or rescue planning often need supporting units such as confined spaces training, gas testing, an EWP yellow card, or first aid. These combinations are common in construction, utilities, mining, and maintenance roles where risks overlap.
Keeping employees compliant also means maintaining clear records. Training certificates, Safe Work Method Statements, equipment inspection logs, and refresher training schedules should be kept up to date and easily accessible. Refresher training every two to three years helps workers stay current and supports safer, more consistent work practices across site.
Permits, licences, and documentation
When working at heights involves a risk of falling more than two metres, the work is treated as high-risk construction work and a Safe Work Method Statement (SWMS) must be prepared before that work begins. According to Safe Work Australia, a SWMS is used to plan how hazards will be identified and managed, and how control measures will be implemented on site.
A SWMS must:
- Identify the high-risk construction work being carried out, such as working at heights
- Specify the hazards and risks involved, including the risk of a fall
- Describe the control measures that will be used
- Explain how those controls will be implemented, monitored, and reviewed
The person conducting the high-risk work, such as a subcontractor, is generally best placed to prepare the SWMS. This should be done in consultation with the workers carrying out the task and other relevant duty holders on site. Safe Work Australia also notes that the principal contractor must obtain a copy of the SWMS before high-risk work starts.
A SWMS must be kept at the workplace and be readily available for inspection for the duration of the high-risk work. If the SWMS is revised, for example, due to changes in site conditions, equipment, or controls, all affected workers must be informed, and the updated SWMS must be followed.
The hierarchy of controls for working at heights
The safest option is always to carry out work on the ground or from a solid construction, wherever possible. When that can’t be done, the law requires risks to be managed using a clear hierarchy of controls. These controls should be considered in order, starting with methods that remove the risk of a fall altogether, and only moving to higher-level controls when lower-level options aren’t reasonably practicable.
The hierarchy below outlines the accepted approach to managing fall risks on site.
1. Fall prevention device
These stop a fall from happening in the first place and should always be considered first. Examples include barriers, scaffolding, guardrails, and elevating work platforms.
2. Work positioning system
Where fall prevention isn’t possible, work positioning systems may be used. These systems support or position a worker at height, such as industrial rope access systems. Workers and supervisors must be trained and competent in their use.
3. Fall arrest system
Fall arrest systems are used when other controls can’t fully remove the risk. These don’t prevent a fall, but reduce injury if one occurs. Examples include safety nets and catch platforms. Training and rescue planning are essential when these systems are used.
Sometimes, a combination of all of the above may be required to provide adequate protection.
Specific height thresholds
What is the minimum height for working at heights?
In Australia, people often refer to the 2-metre guideline when talking about working at heights. That’s because a risk of falling more than 2 metres is commonly used as a clear trigger for higher-risk work under the model WHS laws. Once work reaches this level, stronger controls and formal documentation are usually required.
That said, safety doesn’t suddenly start at 2 metres. If work is being done below this height and there’s still a chance of someone injuring themselves, the risk needs to be managed. This is generally done by:
- Looking for anything that could cause a fall
- Thinking about who could be harmed and how it might happen
- If a risk is present, considering safer ways to carry out the task
- Taking action to remove the risk where possible, or reduce it if it can’t be eliminated
If the risk assessment shows a higher level of risk, physical fall-prevention measures and a Safe Work Method Statement should be used.
What is the maximum height for working at height?
There is no legislated maximum height for working at heights in Australia. Instead, the law requires that all work at height is properly risk assessed, regardless of how high it is. Practical limits come from manufacturer specifications for equipment like scaffolds, EWPs and platforms, as well as the level of supervision and controls that can be safely maintained as height increases.
At what height is fall protection required?
Fall protection is required wherever there is a risk of a fall that could cause injury, and in construction, this typically applies once work is carried out above 2 metres. Controls may include guardrails, a safety net, or a fall-arrest system, such as harnesses and lanyards. All equipment must be regularly inspected, and workers must be trained and competent in its correct use.
At what height is scaffolding required?
In Australia, scaffolding is generally required where there is a risk of a person or object falling four metres or more from the platform. At this height, a high-risk work licence is required to erect, alter, or dismantle the scaffold.
However, a Safe Work Method Statement is required for any construction work where there is a risk of a fall of two metres or more, even if a scaffolding licence isn’t needed.
Turning requirements into safer work practices
Effective working at heights practices come down to judgement. Knowing when a task is tipping into higher risk, recognising when conditions have changed, and taking the time to put the right controls in place makes a real difference. Height thresholds, SWMS documentation, and fall prevention devices are there to support those decisions and keep everyone aligned on site.
The safest sites are the ones where workers are trained, confident, and comfortable speaking up early. When people understand the risks of falls and how to manage them properly, safety becomes part of how the job runs, not something added on at the last minute.
