Welcome to HL7 Australia

Welcome to HL7 Australia. We are a membership-based not-for-profit public company limited by guarantee that exists to facilitate adoption of e-health in Australia by promoting effective use of standards and products developed by HL7 International and supporting their enhancement to meet local needs.

Health Level Seven® International (HL7®) is the global authority on standards for interoperability of health technology with members in over 40 countries.

About HL7 Australia

Australia has been an early driver for the internationalisation of HL7.

HL7 Australia began in Australia in 1998 under the auspices of Standards Australia IT-14 Health Informatics Committee.

In May 2002, it was first incorporated independently as the HL7 Australasia User Group.

In March 2010 the name changed to HL7 Australia;  and in December 2019 HL7 restructured, becoming a limited company.

HL7 Australia Ltd remains the local affiliate of HL7 International. Our members are representative of those using and benefiting from HL7 Standards in Australia. 

HL7 Australia Ltd continues to make an important and significant contribution to the work of HL7 International and global health informatics standards development more generally.


HL7 Australia’s objects are to:

  • Promote effective use of HL7 International standards and products
  • Support and promote interoperability of health information systems
  • Promote the widespread, consistent use of standards developed by HL7 International and by HL7 Australia across the Australian health sector
  • Be recognised as the principal body in Australia promoting the development, understanding and adoption of standards developed by HL7 International and HL7 Australia
  • Be a respected and influential body in Australia and internationally in the health information industry


Create a collaborative and open community, developing interoperability standards and promoting their adoption to support and enhance world leading healthcare in Australia


In late 2020 the Board of HL7 Australia convened a series of workshops with members and stakeholders to input into a strategy for the company for the coming three years (2021-2023).

Four strategic objectives emerged:

  1. Position HL7 in national framework for interoperability standards
  2. Support development of localised standards
  3. Grow our community
  4. Promote adoption and conformance to HL7 AU standards

For each of these strategic objectives, a series of actions and deliverables have been identified and indicative prioritisation given to these. To view the 2021-25 strategic plan please click here.

HL7 Australia Standards Work Groups

HL7 Australia has four Work Groups, broadly modelled after their HL7 International counterparts, these are:

  • Orders and Observations (OO) Working Group
  • Patient Administration (PA) Working Group
  • Medications (Medications) Working Group
  • Child Health Working Group

HL7 Australia Work Groups, modelled after their HL7 International counterparts are:  

Orders & Observations:  This group was formed as one of its first by HL7 Australia to address transmission of observation requests and reports. It mirrors the Hl7.org working group.  

The mission of the Orders and Observation work group is to define information exchange capabilities to support the order/scheduling and clinical event management/reporting requirements between the stakeholders in healthcare organizations regarding patients, non-patients, people, other species, or inanimate objects. These information exchanges are not limited to intra-organizational transactions, but cross organizational boundaries. These information exchanges may involve messages, documents, services, profiles and other HL7 constructs.

The initial focus is pathology but as for the Hl7.org O&O the scope may cover general observations, findings, impressions recorded as quantitative, qualitative, codes, or narrative text.  HL7 v2 is now being used for such content in Australia.

The Orders & Obs Co-chairs are:

  1. Dr Michael Legg, RCPA and Michael Legg & Associates
  2. Dr Andrew McInytre, Medical Objects

Patient Administration: The Australian Patient Administration Work Group is currently active in producing FHIR profiles that cover how to represent the PA resources for use in the Australian context. Most notably profiles for Patient and Practitioner and their Identifiers.

The Patient Admin Co-chairs are:

  1. Brian Postlethwaite, Telstra Health
  2. Brett Esler, Oridashi

Medications: The HL7 Australia Medication Work Group provides a forum for stakeholders and interest parties to contribute and discuss matters related to clinical and technical contents of medication information.
The mission of this WG is to assure that these medication information contents:

  • meets the requirements of prescribing/ordering, dispensing and supply, administration and use
  • supports the understanding and review of patient’s medical profile and management
  • are interoperable (clinically and technically)

The Medications Co-chairs are:

  1. Johnson Law, Fred IT Group
  2. Matt Cordell, CSIRO

Child Health: The Child Health Work Group supports the HL7 Australia mission by defining the requirements and specifications to support interoperable information exchanges of child health data, including birth records, immunisations, health checks, observations and developmental milestones.

The Child Health Co-chairs are:

  1. Reuben Daniels, Saludax
  2. Nichol Hill
  3. Shovan Roy

The Board of HL7 Australia expresses thanks to these individuals and their supporting organisations for their participation and future contribution to the growth of a new Australian Standards Development Initiative.


The Board is planning a program of monthly events for members and interested parties. Keep an eye on our News posts for updates. 

If you missed our latest event on 1 December 2021, when Grahame Grieve will host Playing with FHIR author, Alissa Knight, and John Moerhke (Co-Chair HL7 International Security Group), for a panel discussion about Alissa’s report, responses to it and what we should learn about API and App security, you can view the recording here.

Legal Obligations of HL7 Australia Membership

Since 2019, HL7 Australia as an association limited by guarantee which places us under federal legislation that clearly outlines all member and director rights and responsibilities. We suggest you familiarise yourself with the rules governing our new association here.

We wish to draw your attention to the obligation that HL7 Australia now carries to make primary contact details of all members available to every member. This is to allow any member to gain enough support to call a General Meeting. By becoming a member, you agree to your contact details being shared in line with federal legislation.

Additionally HL7 Australia is required under the constitution to charge all new members a one-off fee of $10 that limits your liability as a member to $10. Once paid, this fee will not be charged on renewal of a membership. For accounting purposes please note this payment is GST exempt.

A policy decision of HL7 Australia is to charge all members that are not renewing their membership a $10 administration fee (inc GST). This will be taken from the initial $10 deposit to simplify administration, rather than refunding that $10 deposit on lapse or termination of membership.


HL7 standards support clinical practice and the management, delivery, and evaluation of health services, and are recognized as the most commonly used in the world.
