A .com.au WHOIS lookup tells you which registrar holds the domain, when its record last changed, its nameservers and its status codes. auDA, which runs the .au registry, publishes these over RDAP. The registered date, expiry date and age stay blank for .au names, because auDA doesn't publish creation or expiry dates.
What a .com.au lookup shows
- Registrar: auDA lists the registrar's corporate entity name. That can differ from the retail brand you bought the domain from.
- Last updated: the date and time the registration details last changed.
- Nameservers: the servers that resolve the domain so it can be found on the internet.
- Status: the registry's status codes for the domain.
The registrant's name and contact emails aren't in the result. auDA removed all email addresses from its RDAP responses, and it never discloses a registrant's street address or phone number. The full public record, registrant name included, is on auDA's own web WHOIS at whois.auda.org.au, which sits behind a CAPTCHA.
Why a .com.au domain shows no expiry date
WHOIS used to show when a .au domain was created and when it expired. Some sellers used those dates to send renewal notices to owners they had no dealings with, so auDA stopped publishing creation, renewal and expiry dates.
If the domain is yours, your registrar or reseller can tell you when it expires. You can also use the password recovery tool on auDA's website. For a domain whose registry does publish dates, such as a .com, the same lookup returns the registered date, expiry date and age.
auDA also limits how many queries one user can send to its web WHOIS and RDAP. If a lookup fails after a run of them, wait and try again. From auDA's WHOIS policy, read in October 2026.
