I see this all the time when checking the whois where an abn or company registration has been cancelled years and years ago and yet the domain name continues to be renewed. I don't look into that that many names so there might be quite be a large number of these. I don't know if the registrars check these details at the time of renewal or only on the initial registration.The ABN for the current registrant was cancelled in 2008. Not sure how any COR wouldn't be against auDA policy.
Binge.com.au is on today's drops, but is showing as recovered. And the ABN has now changed to a valid one.
