You will need an Individual Healthcare Identifier (IHI) to get your proof online if you are not eligible for Medicare.
If you don't already have an IHI, you can apply for one and link it using the Individual Healthcare Identifiers service (IHI service) through myGov.
To do this, sign in to myGov then:
Select Services or Link your first service.
Select Individual Healthcare Identifiers service and then follow the prompts.
