One Fall, One Investigation, One Prosecution: What WorkSafe Actually Does After a Rooftop Incident

A building owner rings the office one Tuesday morning. A WorkSafe inspector has arrived unannounced and is now walking across the roof with a clipboard. What happens next will shape the next twelve months of their business life.

Most building owners operate under one assumption: if nobody has fallen, we are compliant. WorkSafe Victoria sees it differently. The regulator does not wait for an injury to investigate. They respond to complaints from workers, conduct proactive audits, and attend incidents. They test whether the person in control of the building has done everything reasonably practicable to prevent a fall from height. That duty is not optional. It is written into the Occupational Health and Safety Act.

When WorkSafe attends a building after a complaint or incident, they are looking for systems and documentation that demonstrate compliance. A certified height safety system installed to the relevant standards. An asset register that records every item, when it was last certified, and when it is due for recertification. Safe Work Method Statements for each type of work. Access records that show who was on the roof, when, and under what authority. If these documents do not exist, the investigation expands.

The kind of improvised setup that gets the job done until WorkSafe arrives or until someone falls

This is not theoretical. In February 2026, WorkSafe Victoria prosecuted a roofing business and secured a total fine of $700,000 across nine offences under the Occupational Health and Safety Act and Regulations. The investigation began after a complaint about lack of fall protection. Inspectors found a worker on a roof with no perimeter guardrailing and no safety harness. The business had failed to use passive fall prevention devices. It had failed to have a SWMS across multiple sites. The fine was issued. The company’s reputation suffered. The legal costs were real.

What most building owners do not understand is how a WorkSafe investigation actually unfolds. The initial finding is often relatively contained. WorkSafe issues a Provisional Improvement Notice — a PIN — identifying the specific issue that needs to be rectified. That sounds manageable. It is not. Closing out a PIN requires demonstrating a solution that WorkSafe is satisfied resolves the problem. WorkSafe does not tell you what the solution is. That is your problem to solve. They evaluate whatever you propose and determine whether it meets the standard. As the list of evidence and documentation required to prove compliance grows, so does the time and cost. A significant workplace safety issue can take twelve months or more of sustained effort to fully resolve, often requiring a specialist health and safety expert to manage the process alongside you.

The building owner who operates defensibly does not end up in this process. They know what WorkSafe looks for and they build their systems before an inspector arrives.

A certified height safety system installed to the relevant Australian Standards provides the first foundation. Our inspection reports name every standard the system has been inspected against — AS/NZS 1891.4:2025, AS 1657:2018, product specifications — and state the next recertification date for each asset. That is not a courtesy. It is the document that answers the first questions in any WorkSafe inquiry. A height safety asset register records every fall arrest device, every anchor point, every guardrailing system, and the certification dates. This register lives with the building, not with a contractor. when this is shared with the sub-contractors, it enables them to build a Safe Work Method Statement that makes sense for the building and the work being completed for what work.

Having a self-retracting lanyard is not the same as using it correctly. WorkSafe investigators know the difference.

This is the documentation that answers every question a WorkSafe inspector will ask. When a certified system is in place, you produce the paperwork, the inspection takes two hours instead of two weeks, and the investigation closes. When it is not in place, WorkSafe expands the inquiry. They contact contractors. They request historical records you have to dig through archived emails to find. The inspection becomes a prosecution inquiry. Your legal advisors become very familiar with your office. The fine and the reputational damage arrive in the same letter.

A roof with no compliant fall protection in place. WorkSafe does not need to wait for an incident to investigate this

The difference between these two scenarios is entirely preventable. One requires a clear system from the beginning. The other is the story every building owner hopes never becomes theirs.

Start with an honest assessment of where you stand right now. Review your current certification reports. Check whether your asset register is current. Confirm that you have a SWMS for every type of work done on your roof. Verify that you hold access records. If any of these is missing or out of date, that gap is what a WorkSafe inspector will find first.

If you want to understand what each standard actually requires for your building, we have put together a Standards Reference Guide covering every standard we inspect against — what it covers, why it matters, and how the minimum frequency that a system needs to be inspected.

This is the compliance record that keeps you out of the investigator’s notebook. Build it before you need it.
