Reducing work-related ill health is a priority for WorkSafe. We have specialists in a range of work health and safety fields who support businesses to manage work-related health risks, and use a range of insights to inform that work.

One insight that helps WorkSafe target our interventions is approximately 900 notifications we receive each year about work-related health concerns. A specialist team reviews those notifications and may follow up if the situation warrants further action. Read more about when we intervene

In the 12 months between July 2022 and June 2023, we received 906 health notifications: 642 were for a physical health condition, and 264 were related to mentally healthy work concerns.
