About domain names

Your domain name (website address or url) helps people find your website on the internet. It’s good to have a domain name that matches your business name or brand so customers can easily find you.

Check if you need to register a domain name

You don’t have to register a domain name to start or grow your business. But you should register for one if you plan to create a website for your business.

Even if your business website isn’t ready yet, you can still register for a domain name. This can ensure the domain you want is available when you're ready to use it.

Register your domain name

You can register your domain name through a registrar or reseller listed on the .au Domain Administration Ltd (.auDA) website. Before you register, make sure you have:

  • checked your domain name is available
  • an Australian Company Number (ACN) or Australian Business Number (ABN) if you want a .com.au or .net.au domain.
