According to ASIC "An Australian company must have a registered office to receive correspondence. A registered office does not need to be the same as the company's principal place of business, but it cannot be a post office box."
To change your Registered Office Address, follow the steps below:
Click on the Company Information link in the left sidebar.
On the Company Information page, click on the 'Change' button in the Registered Office panel (Image 1).
