As an Identity Provider:
The eduroam AU national policy requires that eligibility for eduroam identity provider participation is restricted to AARNet customers. The reason for this is that the AARNet access agreement is part of the policy hierarchy. Hence only institutions under an AARNet access agreement can operate as an eduroam identity provider.
As a Service Provider only:
Any institution with a business case for participating in eduroam AU may operate as an eduroam service provider, i.e. provide access to their local network to users from eduroam identity providers.
