I used to think there was meant to be a distinction between .org.au and .asn.au, but looking at AuDA, I don't really see it.
My favourite is, of course, .id.au.

When auDA was created in the late 90's, the policies were harmonized and .com.au and .net.au got the same policies, .org.au and .asn.au got the same policies, etc. It has further evolved since based on policy panels I think they conduct every 5 years.
