How can I check the status of a domain name to see if it is available?

You may use AusRegistry's WHOIS Check tool at http://whois.ausregistry.com.au/whois/whois_check.jsp.

Entering a domain name will only show you if it is available or not available for registration. You can perform any number of look-ups using this tool.

Please use the .au WHOIS tool to view registration information about a .au domain name.
