If you do nothing else, this step is the most important. There are a variety of domains to choose from. The most common are either .com or .com.au. These relate to commercial enterprises, and should be as short as possible so that your customers can remember it!
SECURE YOUR DOMAIN NAME
When purchasing a domain name for your business, it is important to remember to purchase both .com & .com.au (if available), or this may lead to your opposition buying it before you do. Or worse still someone may secure the domain name and resell it back to you for an inflated price. Other domains are .net.au, which signifies an Internet business.
