Working at Heights in Australia: Requirements, Regulations, and Best Practice

Falls from height remain the second leading cause of workplace fatalities in Australia, accounting for 13% of all deaths in 2024. The regulatory framework for managing fall risks is well-established — the challenge is consistent implementation.

When does work at height trigger SWMS and permit-style documentation?

Under the model WHS Regulations, work where a person could fall more than 2 metres is classified as high-risk construction work. This means:

Many businesses also require an internal authorisation or permit-to-work for height work that documents:

The hierarchy of controls for fall prevention

The model Code of Practice: Managing the Risk of Falls at Workplaces (Safe Work Australia) mandates applying the hierarchy of controls:

1. Eliminate the risk. Can the work be done at ground level? Can prefabrication reduce time at height?

2. Substitute. Can an elevated work platform (EWP) replace a ladder? Can a scissor lift replace scaffolding for short-duration tasks?

3. Isolate. Install physical barriers — guardrails, perimeter screens, hole covers. Passive fall prevention is always preferred over active systems.

4. Engineering controls. Industrial rope access systems, safety mesh, catch platforms, and travel restraint systems. These require specific training and competency.

5. Administrative controls. Safe work procedures, permit-to-work systems, supervision, toolbox talks, and exclusion zones.

6. PPE. Full-body harnesses, lanyards, self-retracting lifelines (SRLs), and anchor points. PPE is always the last line of defence, never the first.

Common non-compliance issues

SafeWork NSW, WorkSafe Victoria, and Workplace Health and Safety Queensland consistently identify:

EWP and scaffolding requirements

Elevated Work Platforms (EWPs): Operators must hold TLILIC0005 — Licence to Operate a Boom-type EWP (over 11m) or equivalent. All EWPs must be inspected before each use per AS 1418.10.

Scaffolding: Must be erected and dismantled by a licensed scaffolder. Scaffolding over 4 metres requires a high-risk work licence (scaffolding — basic, intermediate, or advanced). Inspections required before first use, after alteration, after adverse weather, and at least every 30 days.

Digital systems for permit-to-work

Paper-based permit systems create gaps — forms get lost, sign-ons are missed, weather changes aren't documented. Digital systems that structure permit requirements in the compliance pack from the task description, capture real-time sign-on data, and are designed to preserve a clear activity history — with client update/delete denied for org audit-log entries and SHA-256 verification on enterprise audit exports — give regulators what they need during an investigation: a complete, timestamped record of who was on site, what controls were in place, and who authorised the work.
