An overseas company has identified Australia as its next market. The business plan is taking shape, potential customers have been identified, and the leadership team is ready to move forward.
Then a deceptively simple question comes up:
What Australian address should the company use?
For overseas founders setting up a company in Australia, this is more than a mailing detail. The registered office forms part of the company’s official corporate information and provides a location where regulatory and legal communications can be sent.
The right arrangement therefore needs to work not only on registration day, but also as the Australian operation develops.
First, What Does a Registered Office Actually Do?
A registered office is the official address associated with an Australian company.
ASIC requires companies to provide a registered office address when they register. The address must be a physical street address in Australia rather than a post office box. ASIC can send official notices and correspondence there.
Importantly, the company does not necessarily have to conduct its everyday business from that location.
For an overseas business with no Australian premises yet, that distinction can be particularly useful. For example, ASIC notes that a company’s registered office may be an accountant’s office. When the premises are not occupied by the company, the company must have the occupier’s written consent to use the address.
The registered office should therefore be thought of as part of the company’s corporate infrastructure rather than automatically as its workplace.
Registered Office vs Business Address: Don’t Confuse the Two
These addresses serve different purposes.
| Question | Registered Office | Principal Place of Business |
| What is it for? | Official company and regulatory correspondence | Main location where the company conducts business |
| Must it be in Australia? | Yes | Yes |
| Can it be a PO Box? | No | No |
| Does the company have to operate there? | Not necessarily | It represents the main operating location |
| Can the addresses be the same? | They can be, where appropriate | Yes, depending on the company’s circumstances |
ASIC requires companies being registered to provide both a registered office and a principal place of business address.
That means an overseas founder should avoid choosing an address simply because it is convenient for receiving mail. Each address needs to accurately reflect its intended corporate purpose.
What Overseas Companies Need to Understand
The first question is actually not about the address.
It is:
How will the overseas business establish its presence in Australia?
An overseas organization may establish a new Australian company or, depending on its plans and circumstances, register an existing foreign company to conduct business in Australia.
Those routes carry different requirements.
For example, an Australian proprietary company generally needs at least one director who normally lives in Australia.
A registered foreign company, meanwhile, must maintain an Australian registered office and appoint a local agent. ASIC also sets specific requirements concerning the availability of the registered office.
So the address should not be decided independently of the entity structure.
When setting up a company in Australia, overseas businesses should first establish what type of presence they are creating and then determine which address arrangement properly supports it.
Three Address Situations Overseas Businesses Commonly Face
There is no single operational setup that applies to every international company.
Scenario A: No Physical Team in Australia
Imagine a US, UK or European business forming an Australian company before hiring its first local employee.
It may not make commercial sense to lease a permanent workplace solely to obtain a registered office.
In this situation, the company may use an appropriate third-party address where the regulatory requirements are satisfied and permission to use the premises has been properly obtained.
The practical priority is reliability.
Official correspondence needs to be received, identified and passed to the appropriate person rather than disappearing into an unattended mailbox.
Scenario B: Employees Are Present, but There Is No Permanent Office
A company may have employees working remotely or across different locations without maintaining a conventional headquarters.
That does not remove the need for appropriate corporate addresses.
Using an employee’s home casually as the registered office can also create practical issues. Company address information is available through ASIC’s companies register, so overseas businesses should consider privacy, continuity and administrative control before choosing an address.
If the employee later moves or leaves the organization, the company could also need to update its records.
A more stable arrangement can reduce unnecessary disruption.
Scenario C: The Company Establishes Local Operations
Suppose the business eventually opens an Australian office from which its team operates.
Its principal place of business may then reflect that operating location.
The company can review whether its existing registered office arrangement still makes sense or whether its corporate address should change as well.
Growth does not automatically mean every company address needs to become identical. The better question is whether each address continues to serve its intended purpose accurately and reliably.
What Makes a Registered Office Arrangement Practical?
Legal eligibility is only the starting point.
For an international company, a useful registered office arrangement should also support day-to-day corporate administration.
Look at five practical factors:
- Reliable receipt of correspondence: Official documents should not remain unnoticed or unattended.
- Document handling: There should be a clear process for directing correspondence to the correct internal or external contact.
- Accessibility: The arrangement must meet the requirements applicable to the entity.
- Continuity: The address should remain dependable as employees, offices and business plans change.
- Compliance administration: Someone should have responsibility for keeping corporate details current when circumstances change.
The last point is easy to underestimate.
A registered office is not something a business chooses once and then forgets. ASIC requires company information to remain current, including relevant address changes.
The Registered Office Is Only One Piece of Australian Expansion
An address can sometimes become the first visible administrative hurdle, but it should not become the entire expansion plan.
The wider journey looks more like:
- Company structure
- Registration
- Registered office
- Corporate records
- Employment
- Ongoing compliance
Each decision affects what comes next.
A business may need to consider its directors and shareholders, internal company rules, share structure, corporate records and ongoing ASIC obligations alongside the addresses provided during registration.
If employees are added later, another layer of local employment and HR requirements enters the picture.
That is why setting up a company in Australia should be approached as the creation of an operating framework rather than the completion of a registration form.
Questions to Resolve Before Establishing the Address
Before confirming the registered office, overseas decision-makers should be able to answer:
- Are we forming an Australian company or registering an existing foreign company?
- Will we have a genuine operating location in Australia from the beginning?
- Who will receive and manage official correspondence sent to the registered office?
- If we use premises we do not occupy, do we have the required consent to use that address?
- Will this arrangement remain practical if our Australian workforce or operations expand?
- Who will be responsible for updating ASIC and maintaining the company’s corporate records when details change?
Those questions turn an address decision into part of a more deliberate market-entry plan.
Build the Local Foundation Properly
Australian expansion rarely hinges on one dramatic decision. More often, problems emerge from smaller requirements that were treated as administrative afterthoughts.
The registered office is one of those details.
Choose an arrangement that satisfies the company’s requirements today while remaining workable as the Australian operation develops. Then make sure it fits properly with the entity structure, corporate records, employment plans and ongoing compliance responsibilities around it.

Frequently Asked Questions
1. Does an Australian company need a registered office address in Australia?
Yes. ASIC requires a registered Australian company to have a registered office that is a physical street address in Australia. A PO Box cannot be used as the registered office.
2. Can an overseas founder use an accountant’s address as the registered office?
Potentially, yes. ASIC specifically gives an accountant’s office as an example of an address that may be used even when the company does not conduct business there. If the company does not occupy the premises, it must have the occupier’s written consent to use the address.
3. Does the registered office have to be the same as the principal place of business?
No. The registered office is used for official company correspondence, while the principal place of business represents the main location where the company conducts business. Depending on the company’s circumstances, they may be different addresses.
4. Can a PO Box be used as an Australian company’s registered office?
No. ASIC requires the registered office to be a physical street address in Australia. A PO Box is not accepted for this purpose.
5. Does an overseas company need an Australian resident director?
If an overseas business establishes an Australian proprietary company, it must have at least one director who normally lives in Australia. Different requirements apply to public companies and to foreign companies registered in Australia, so the entity structure should be established before appointments are made.
6. Is registering a foreign company the same as forming an Australian company?
No. They are different routes. A business may establish a new Australian company, while an existing foreign company conducting business in Australia may need to register with ASIC as a foreign company. Registered foreign companies have additional requirements, including maintaining an Australian registered office and appointing a local agent.
