Certificate of capacity

A certificate of capacity is a medical document in Australia that evaluates a worker’s capacity to return to work after a work-related injury or illness. 

It is a primary requirement under Australian workers’ compensation systems. It is also recognised by WorkSafe authorities in each state and territory. 

Purpose and utility 

  • Confirms whether a worker has full, partial, or no capacity to work. 
  • Facilitates access to workers’ compensation entitlements. 
  • Enables employers to plan suitable duties and return-to-work arrangements. 
  • Guides insurers on treatment requirements and anticipated recovery periods. 

Issuing and validity 

  • It is valid for the period specified. 
  • It must be renewed if the worker’s capacity changes or the certificate expires. 

Essential requirements 

  • Details of the workers’ injury or medical condition. 
  • A clear statement outlining work capacity and any restrictions. 
  • Recommended hours, duties, or limits. 
  • The healthcare provider’s name, provider number, and signature.  

Australian workers should understand certificates of capacity, as they directly impact income support, job security, and legal rights after a workplace injury. Employers must use valid certificates to follow workers’ compensation laws and ensure safe return-to-work practices.
