You may have received emails or reminders about registering the “.au” version of your business domain. Your current website domain probably ends in “.com.au” or “.net.au”. The “.au” domain is a new, shorter domain option.
You do not need to register for a “.au” domain, but if you do not, others will be free to register. As the domain holder for your current website, you will have priority access to register for the “.au” domain. You must register your new domain by 7.59am on 21 September in Western Australian time.
