Hi @Michael
Thank you for posting this in Microsoft Q&A.
Currently, the Australia location is not supported for External ID for customers. Our team is working on adding the Australia location to the new External ID/CIAM tenant. The location selected determines the datacenter of your tenant, and it must be chosen very carefully because it cannot be changed after creation
As of now, we can't share any dates on when it will be possible to create an External ID tenant in Australia. Keep checking https://learn.microsoft.com/en-us/entra/external-id/customers/whats-new-docs for monthly updates on external tenant.
Hope this helps. Do let us know if you any further queries.
Thanks,
Navya.
