A national business names register came into force on 28 May 2012 and is administered by ASIC (Australian Securities and Investments Commission).
Registration of a business name is required where a person or company does not trade under their own name. Up until the new register was created separate registrations were required in each state.
Under the new regime only a single registration is required. As a result all business names on state and territory registers have been merged into a single register. If you hold registrations of identical business names in two or more states or territories you have the option of continuing with just a single registration or maintaining all of them.
Unlike a registered trade mark, a registered business name gives no right to use that name. For the right to use a name in relation to certain goods or services and to prevent others from using that name, or a similar name you need a register a trade mark.
