"... Also .com.au requires a business number to register. There are other restrictions too. Similarly .asn.au can only be registered by non-commercial organisations. ..."
Thanks to kre (Kevin Robert Elz) ~ http://en.wikipedia.org/wiki/Kevin_Robert_Elz you cannot get a ".com.au" domain name without having a registered business name. The idea was to stop domain name speculation ~ http://www.passioncomputing.com.au/Articles/Australian-domai... Good in the short term when one person was administering domain names, not so good now as it adds extra overhead for a ".com.au" small market.
