See [Comparison with other national and international IGs](comparison.html) for a comparison between AU Core profiles and profiles in other implementation guides.

### Profile specific implementation guidance
- An individual's IHI **SHOULD** be used in `Patient.identifier` if available, in preference to Medicare or DVA numbers.
- See guidance on the construction of identifiers in each Identifier profile and the section on [Business Identifiers](https://build.fhir.org/ig/hl7au/au-fhir-base/generalguidance.html#business-identifiers) in AU Base.
- This profile supports the sex, gender, and related concepts of: Name to Use, Gender Identity, and Individual Pronouns. See the [Sex and Gender](sex-and-gender.html) page for guidance on exchanging sex and gender related concepts conformant to AU Patient Summary.
- See the [Representing communication preferences](https://build.fhir.org/ig/hl7au/au-fhir-core/general-guidance.html#representing-communication-preferences) section for guidance.
- When constructing an address:
  - an international address can be represented using the core [Address](http://hl7.org/fhir/R4/datatypes.html#Address) data type
  - an Australian address **SHOULD** be represented using the [Australian Address](http://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-address.html) data type profile
 - Patient names can be provided as a text representation in `name.text` and/or parts such as `name.family` and `name.given`. 
  - `name.text` specifies the entire name as it is intended to be displayed. This may be provided instead of, or as well as, the specific parts. It is important to note that the presence of parts of a name, e.g. `name.family` and `name.given`, do not imply that `name.text` is known or needs to be supplied.
