The move to direct .au suffixes was put off after the government completed a review of the auDA management framework last year and said it was unfit for purpose.
Direct registration means that rather than registering a .com.au domain, one would be able to register an .au domain instead.
An auDA spokesman told iTWire in response to queries that the date of implementation would depend on whether the board approved the proposed policies.
The Opposition Labor Party last year questioned the need to switch, asking what problem direct registration was trying to solve.
One of the questions that has to be decided is who gets priority to obtain an .au domain – the person who owns the .com.au, the .net.au or the .org.au.
iTWire understands that if multiple contenders exist for the same .au domain and all or two make a claim, then the contenders would be asked to pay a sum in order to remain in the running to get the .au domain.
The auDA spokesman said: "Registrants of .au domains will have six months, following the commencement date, to apply for priority access to the exact match of their name in the .au namespace.
"Where there is more than one applicant for a name who has registered their name prior to 4 February 2018, it will be up to those registrants to negotiate with each other as to who will register the .au name.
"Given that there are approximately 2.8 million names in .com.au, and then only about 0.2 million names in the next biggest name space (.net.au), in the majority of cases there will be no contention between holders of domain name licences and the holder of a .com.au domain name licence will be eligible to apply for, and receive, the corresponding .au domain name.
"Any existing names that have not received an application for the corresponding .au domain name in the six months priority registration period will then be released on a first-come, first-served basis."
