For overseas businesses seeking to establish a subsidiary or branch in Australia, one of the most important requirements under the Corporations Act 2001 is nominating a registered office address with the Australian Securities and Investments Commission (ASIC).
A registered office address is a legal necessity. This physical street address (PO Boxes are not permitted) is where ASIC and other government agencies send you official notices, including legal documents, compliance reminders, and tax correspondence. Ensuring this address is reliable and monitored is essential because any documents sent here are considered officially received.
Key requirements for a registered office address
When registering a company in Australia, you must provide both a registered office address and a principal place of business address to ensure full compliance with ASIC requirements.
Registered office address
The registered office address must be a real, physical street address within a state or territory of Australia. It does not need to be the location where your company conducts daily business, but you must have the owner’s written consent if using a third-party office.
Principal place of business address
In addition to the registered office address, you must also provide a principal place of business address, where your company’s operations are primarily conducted. Both addresses must be kept up to date with ASIC.
Ongoing compliance obligations
Company officeholders (directors and secretaries) have continuous legal responsibilities after registration. Maintaining a compliant registered office address ensures that your international business does not miss critical correspondence, reducing the risk of penalties or compliance breaches.
