Every company registered in Australia must maintain a registered office address. This is not optional, it is a legal requirement under the Corporations Act 2001. Getting it wrong, using a PO box, or failing to update it can lead to missed legal notices, ASIC penalties, and in extreme cases, compliance action against your company.
This guide explains exactly what ASIC requires, what types of addresses are and are not acceptable, and how to set up a compliant registered office including the virtual address option.

What Is a Registered Office Address?
A registered office is the official legal address of a company as recorded with ASIC.
It is the address where:
- ASIC sends all official company correspondence
- Courts serve legal documents on the company
- Members of the public can inspect certain company documents during business hours
- Government agencies and regulators direct formal notices
Under the Corporations Act 2001, every Australian company (Pty Ltd, Ltd, and other registered company types) must maintain a current registered office address at all times.
The obligation begins the moment the company is registered and continues until the company is deregistered.
Who Needs One?
Every registered company under the Corporations Act 2001 must have a registered office.
This includes:
- Proprietary limited companies (Pty Ltd) by far the most common type
- Public companies (Ltd)
- Foreign companies registered to carry on business in Australia (which have an Australian Registered Body Number, ARBN)
Who Does Not Need a Registered Office?
- Sole traders (you have a business address for ABN purposes, but no formal registered office requirement)
- Partnerships (partnerships register an ABN but are not companies)
- Trusts (the trustee may be a company with a registered office, but the trust itself does not)
ASIC's Specific Requirements
ASIC's requirements for a registered office are set out in the Corporations Act 2001, sections 142–145.
The address must satisfy all of the following:
1. Physical Street Address in Australia
The address must be a real physical location with a street number and name, in an Australian state or territory.
It cannot be an overseas address.
2. Not a PO Box
PO boxes, private mail bags, and post office-only addresses are explicitly not acceptable.
The address must be a premises where documents can be physically served.
3. Accessible During Business Hours
The registered office must be open and accessible to the public for a minimum of three hours on each business day, between 9am and 5pm.
Someone must be present and able to receive documents.
4. Able to Receive Service of Legal Documents
Legal documents served at the registered office are deemed to have been served on the company regardless of whether anyone actually reads them.
The premises must be capable of receiving and holding documents securely.
5. Occupier's Consent (If Third-Party Premises)
If the registered office is not premises owned or leased by the company itself, the occupier must give written consent to the company's use of the address for this purpose.
ASIC can request evidence of this consent.
What Is NOT Acceptable
ASIC will reject or flag the following:
PO Boxes
Not a physical street address.
Overseas Addresses
Must be located in Australia.
Residential Addresses (in Some Circumstances)
Technically permitted, but:
- The accessibility requirements (3 hours daily) are difficult to satisfy from a residential property
- The privacy exposure is significant
Virtual Mailboxes Without Staffed Premises
A digital mailbox with no physical presence does not satisfy the accessibility requirement.
Unstaffed Locations
If nobody is available during business hours to receive documents, the address is non-compliant.
Addresses You Do Not Have Permission to Use
You must have the occupier's written consent.
Registered Office vs Principal Place of Business
ASIC distinguishes between two separate addresses that companies must maintain.
Registered Office
The formal legal address for ASIC records and service of documents.
This is the address that appears first on the ASIC public register.
It must meet all the requirements above.
Principal Place of Business
Where the company mainly conducts its business operations.
Examples:
- A home office
- A commercial office
- A coworking space
It can be the same as the registered office, or different.
For most small businesses and remote-operating companies, the two addresses are different.
Typical Setup
Registered Office: Virtual address at Space Penguin (Sydney or Melbourne)
Principal Place of Business: Home, coworking space, or wherever the business genuinely operates
This is entirely legal and is the standard arrangement for tens of thousands of Australian companies.
You are not misrepresenting your business by having a different registered office and principal place of business; the two addresses serve different purposes.
Using a Virtual Address as Your Registered Office
A virtual address satisfies ASIC's registered office requirements if:
- It is a real physical street address at commercial premises (not a PO box)
- The premises are staffed and accessible for at least 3 hours between 9am and 5pm on business days
- The provider can receive legal documents on behalf of companies registered at the address
- The provider gives you a signed occupier consent letter
Space Penguin's Sydney and Melbourne premises are staffed during business hours.
We:
- Receive legal documents on behalf of registered companies
- Notify customers promptly
- Provide signed occupier consent letters to all ASIC customers as standard
Benefits of Using a Virtual Address
Privacy
Your residential address does not appear on the ASIC public register.
The register is publicly searchable, so protecting your home address from day one matters.
Professionalism
A Sydney or Melbourne address on the ASIC register and company documents signals an established business presence.
Reliability
A staffed commercial premises is more reliable than a home address for receiving legal documents and official notices.
Compliance Confidence
You never have to worry about whether someone was home when an ASIC notice arrived.
The Occupier Consent Letter
The occupier consent letter is a signed document from the owner or occupier of the registered office premises confirming consent to the company's use of their address.
ASIC requires this whenever the registered office is not premises owned or leased by the company.
This includes all virtual address arrangements.
What the Letter Must Include
- The full registered office address
- The company's name and ACN
- A clear statement of consent from the occupier
- The occupier's signature and name
- The date
When You Need It
- When registering a new company
- When updating an existing company's registered office
- If ASIC requests evidence of consent
Space Penguin provides a signed occupier consent letter to every customer who uses our address for ASIC registered office purposes.
Keep this document as evidence of compliance.
How to Register or Update Your Address with ASIC

You must notify ASIC of any change to your registered office address within 28 days.
Failure to do so can result in:
- Late fees
- Compliance action
- Potential ASIC penalties
What Happens If You Don't Comply?
Missed Legal Notices
Documents served at your registered office are deemed served on the company regardless of whether you actually received them.
If your address is non-compliant and documents are not properly received, you may be subject to:
- Default judgments
- Winding-up orders
- Other legal consequences
without ever knowing proceedings were initiated.
ASIC Enforcement
ASIC can take compliance action against companies that fail to maintain a compliant registered office.
This may include:
- Formal warnings
- Fines
- Deregistration in extreme circumstances
Director Liability
Directors have personal obligations to ensure their company maintains proper ASIC registrations.
Persistent non-compliance can expose directors to personal liability.
Banking and Contract Issues
Banks and large organisations regularly review ASIC records.
An outdated or non-compliant registered office address can trigger:
- Account reviews
- Contract complications
- Additional compliance checks
Frequently Asked Questions
Can I Use My Accountant's or Solicitor's Office as My Registered Office?
Yes.
This is common practice.
Your accountant or solicitor must:
- Give written consent
- Meet ASIC's accessibility requirements
Always confirm they are willing to act in this capacity before listing the address.
Can I Use My Home Address as My Registered Office?
Technically yes.
However:
- Your home address becomes publicly searchable on the ASIC register
- The 3-hours-per-day accessibility requirement can be difficult to satisfy
A virtual address avoids both issues.
What Happens If My Virtual Address Provider Closes or I Cancel My Plan?
You must update your ASIC registered office address immediately.
Never leave ASIC records pointing to an address you no longer control.
Does My Registered Office Need to Be in the Same State as Where I Operate?
No.
Your registered office can be located in any Australian state or territory.
For example:
- A Sydney business can have a Melbourne registered office
- A Melbourne business can have a Sydney registered office
How Many Companies Can Share the Same Registered Office Address?
There is no limit.
Virtual address providers and accounting firms commonly act as registered office for dozens or hundreds of companies.
ASIC is fully aware of this practice and it is not a compliance issue.
Space Penguin provides ASIC-compliant virtual addresses in Sydney and Melbourne signed occupier consent letters included as standard. From $20/month.
