Please Note: Under the Domain Name Eligibility and Allocation Policy Rules for Open 2LDs, a registrant may not register a domain name for the sole purpose of resale or transfer to another entity. Where a registrant is found to have breached this policy rule, auDA reserves the right to cancel the domain name licence and delete the domain name.
Now excuse me while I disappear for another 10 years.
the key part there is "sole purpose" so if you register the domain to monetize it before you sell it, even for a day of parking, it is all good then as it was not just for "sole purpose"
