Hello If an Australian company had a website that sold goods or services Australia wide, would that company have to register their trading name in each State/Territory? Each State/Territory seems to have the following rule: "If you wish to carry on business in another State or Territory, the business name must also be registered there." Can anyone provide information about how this applies to websites.. Does offering goods or services interstate constitute "carrying on business"? *In this circumstance the company name will be different to the trading name* Thanks for any feedback.
