Expired testing certificates can be resolved by contacting Services Australia Developer Support at: [email protected]

They will likely suggest 2 options:

  • Reissue the certificates with the same HPI-Os (can take longer)
  • Issue new certificates with new HPI-Os (this is usually quicker) 

National Authentication Service for Health (NASH) Public Key Infrastructure (PKI) certificates let healthcare providers and supporting organisations securely communicate and exchange health information electronically. These certificates:

  • are used to access the My Health Record system
  • provide confidence in the integrity of information transmitted, and
  • provide secure exchange of health information with other healthcare providers
