A company's principal place of business is the physical address where it actually conducts its main activities, recorded separately from its registered office with ASIC. For many small companies, this is the same address as the registered office, though it doesn't have to be. It must be a real street address, not a PO Box.

Understanding the fundamentals of Australian business setup is essential for any entrepreneur or sole trader. Whether you are just starting out or looking to optimise your existing setup, understanding Principal place of business is an important step.
