Should I use a .com or .com.au?

Choosing between a .com and .com.au domain can be difficult, but there are a few things to consider. A .com.au domain requires proof as a valid Australian business by requiring either ABN or ACN registration, whereas anyone can register a .com domain without any legitimate related business. If you're targeting an Australian audience, it might be worth considering using a .com.au domain to ensure customers know your site is local. However, if you're targeting a global audience, using the more common .com domain may be more appropriate. Ultimately, the decision depends on your specific needs and what you hope to achieve with your website.
