AU Base on FHIR R4


This implementation guide is provided to support the use of FHIR®© in an Australian context.

This document is a working specification that is expected to be implemented and tested by FHIR®© system producers to enable feedback to improve the content of this guide.


This document presents Australian use concepts defined via FHIR processable artefacts; these are collaborative outputs with agreed approaches to varied kinds of healthcare related information based on the core FHIR R4 specification.

  • Profiles - are useful constraints of core FHIR resources and datatype for Australian use
  • Extensions - are FHIR extensions that are added for local use, covering needed Australian concepts
  • Terminologies - are defined or referenced code systems and value sets for Australian context

FHIR profiles are managed under HL7 Australia working groups and projects:

Some profiles indicate the responsible working group, or enquires can be directed to the Working Group Liaison Officer


This document is a working specification that may be directly implemented by FHIR®© system producers.

Information contained in this document is aimed at providing guidance on representing Australian local concepts using FHIR. This includes code systems, extensions and profiles on base FHIR types. The content of the implementation guide is general in nature and seeks to provide a ‘how-to’ guide when representing concepts, it includes core base profiles that can be further constrained for a particular usage.

FHIR®© connectathon events are key to the verification of the guide as being suitable for implementation. This implementation guide will be used as the basis for Australian connectathon events.


This guide is the product of collaborative work undertaken with participants from:

  • Australian FHIR Implementers Community
  • HL7 Australia Working Groups
  • Australian Digital Health Agency
  • Secure Messaging Technical Working Group
