.au WHOIS Lookup: auDA Records and Eligibility
Australia's .au entered the root zone on 5 March 1986 and is administered by .au Domain Administration (auDA). WHOIS queries are answered by whois.auda.org.au, and an RDAP service runs at rdap.cctld.au. auDA has signed the zone with DNSSEC and publishes its DS record in the root. Registering a .au name requires a connection to Australia, and the WHOIS record shows the basis on which each name was granted.
A .au reply has 21 fields. Besides the registrar with its abuse email and phone, the status codes, the name servers and a DNSSEC line, it holds three eligibility lines and a Status Reason line that explains the current status in words. Neither a creation date nor an expiry date is published, and the only date in the reply is Last Modified. For eligibility data under another country extension, see the .us WHOIS lookup; for another Asia-Pacific record, the .my WHOIS lookup.

WHOIS FAQ
How do I find out when a .au domain expires?
You cannot find it through WHOIS, because auDA publishes no expiry date for .au names. The RDAP record is no help either, since its only event is the last change. The registrar managing the name holds the renewal date, so ask that registrar or check the account the domain was registered through.
What do the eligibility fields in a .au WHOIS record mean?
The eligibility fields show the basis on which the holder qualified for the .au name. Eligibility Type gives the kind of basis, Eligibility Name the name it is registered under and Eligibility ID the matching identifier. Together they let you check whose connection to Australia the registration relies on.
What does Status Reason mean for a .au domain?
Status Reason is the line where auDA explains the current status of a .au name in words. Status codes say what is blocked, and this line adds why. Most registries give no reason in the reply at all. If your .au name is in a state you did not expect, read this line first and then take the question to your registrar.
Can I see who holds a .au domain?
Yes, a .au record names the holder in its Registrant line and gives a contact ID and contact name for both the registrant and the technical contact. Postal addresses, phone numbers and email addresses are not published. To report abuse, use the registrar's abuse email and phone number from the reply.
Why does whois.com.tr show fewer fields for a .au domain?
The whois.com.tr result screen reads .au data from the RDAP service, which returns the registrar, name servers, status, last change and DNSSEC state. The eligibility lines, Status Reason and the holder's name exist only in the port 43 reply from whois.auda.org.au. If you need them, query that server with any command-line WHOIS client.
Can I register a .au domain as soon as it shows as available?
Not always, because availability is only the first condition for a .au name. An unregistered name shows as available on the result screen, yet auDA also requires the holder to have a connection to Australia, and the registrar checks it when you apply. If you do not meet that rule, the registration fails even for a free name.
