Register your domain name with Australian Website Hosting.
What is a domain name? A domain name is simply a unique name on the Internt that identifies a website and is generally used by typing it into a web brower. An example of a domain name would be "google.com" or "australianwebsitehosting.net.au". To use a domain name you must register it and this can only be done if it is not already registered by someone else.
