You can conduct any number of businesses/activities under the same ABN provided they all operate under the same business structure. If your second or subsequent business operates under a different structure, you need to apply for separate ABNs for each new business structure.
In Australia, the Australian Business Number (ABN) is a unique identifier that allows businesses to interact with various government departments and agencies. It is possible to operate multiple businesses under a single ABN, provided that all the businesses are structured the same way. This means that if you have several business ventures that are all sole proprietorships, for example, they can all fall under one ABN.
However, if you decide to start a business with a different structure, such as a partnership or a corporation, then you will need to apply for a separate ABN for that entity. It's important to ensure that all your business activities are accurately reflected in the Australian Business Register, as this information is public and can be accessed through the ABN Lookup website.
