I'm sorry, I'm not quite sure about the specific situation in Australia. Cryptocurrency regulations vary from country to country, and Australia may have its own unique set of rules and policies. However, in general, cryptocurrency is not banned worldwide, but rather subject to different levels of regulation and supervision. If you want to know more about the regulations in Australia, I suggest you consult with local financial regulatory agencies or legal professionals. They will be able to provide you with more accurate and detailed information.
