I have come across places where the email addresses include 
<anything>@example.com.au   which is/seems contrary to your statement 
that domain name hosts will often limit the number of email addresses to 
1.  Is allowing <anything>@example.com.au an unusual thing, is it 
something that one would typically pay extra for, or is it just that 
they put it all into one mailbox?
