Registered Address in Australia: What It Is and How to Set Up

Your registered address seems simple, but it carries real legal weight for Australian businesses. It’s where official notices are sent, regulators look for you, and-if something goes wrong-where documents can be served.

If you’re setting up a new venture or tightening your compliance, getting your registered address right from day one will save headaches later. In this guide, we’ll explain what a registered address is, how it differs from your principal place of business, whether you can use a home or virtual office, and the practical steps to set it up or change it correctly in Australia.

What Is A Registered Address In Australia?

In Australia, a company must have a “registered office” in Australia recorded with the Australian Securities and Investments Commission (ASIC). This is the company’s official address for legal and government communications. It must be a physical street address in Australia-so not a PO Box-and it’s the place where documents can legally be served on your company.

For other business types (like sole traders or partnerships) that register a business name, you’ll also provide addresses in your registrations. While the terminology can differ slightly, the concept is similar: regulators and the public need a reliable address to reach the business or its owners for official purposes.

Why it matters:

• It’s the legally recognised point for service of documents (for example, court documents or statutory notices).
• Government agencies and banks will rely on it for official correspondence.
• It appears on public registers, so accuracy and privacy considerations are important.

If you’re forming a company, you’ll set your registered office as part of your company set up and provide it to ASIC at registration.

Registered Office Vs Principal Place Of Business: What’s The Difference?

It’s common to mix these up. In practice, many businesses use the same address for both-but they’re not the same thing.

Registered Office (Companies)

• The company’s official legal address for service of documents and regulatory notices.
• Must be a physical street address in Australia (not a PO Box).
• If you don’t occupy the premises, you must have the occupier’s consent to use the address as your registered office.
• Should be accessible during stated hours so documents can be delivered and acknowledged.

Principal Place Of Business

• The address where your day-to-day operations primarily occur (for example, your shop, clinic, or head office).
• For ASIC records, companies also list a principal place of business.
• For business name registrations (sole traders/partnerships/companies), the principal place of business must be a physical address in Australia.

Postal Or Mailing Address

• Often a PO Box or locked bag to receive mail securely.
• This is optional and can be different from your registered office and principal place of business.

Think of the registered office as your business’s “legal front door.” Your principal place of business is where you actually do the work. Your postal address is simply where you prefer mail to go.

Can You Use A Home Or Virtual Office As Your Registered Address?

Yes-subject to some important rules.

Using A Residential Address

You can list a residential property as a registered office or principal place of business if it’s in Australia and you (or the occupier) consent. Many startups begin this way, especially if they’re operating online or from home initially.

That said, consider privacy and practicality. Registered addresses can appear on public registers. If you’d prefer not to publicise your home address, consider alternatives like a serviced office or professional address provider. We’ve covered pros, cons and privacy considerations in detail in our guide to using residential addresses for company registration.

Using A Virtual Or Serviced Office

You can use a serviced or virtual office as your registered office if the provider consents in writing and the address is a physical Australian street address. Ensure the provider will actually receive and forward legal documents during business hours. If your arrangement only offers mail scanning with limited access hours, it may not meet the expectations for service of documents.

Using A Co-Working Space

Co-working spaces can work as a principal place of business or registered office, but make sure your agreement allows it and the operator provides consent. If you’re occupying a desk or area on flexible terms, it’s wise to have a clear Property Licence Agreement that confirms your rights to use the address and receive official notices there.

Practical tip: whichever address you choose, set up reliable mail-handling and document-notification processes. Missed notices can lead to default judgments or compliance penalties.

How To Set Up Or Change Your Registered Address (Step-By-Step)

Whether you’re registering a new company or updating an existing business, follow these steps to get your registered address right.

1) Decide Which Address Suits Your Risk And Privacy Needs

Weigh the trade-offs between using a home address, your operating site, or a serviced office. Consider who visits, who handles mail, and what’s publicly visible. If multiple founders are involved, align on the approach and document it for your governance records (for example, in board minutes, especially if your company has a Company Constitution guiding decision-making).

2) Confirm Occupier Consent (If You Don’t Occupy The Premises)

The Corporations Act requires you to have consent from the occupier of the premises to use it as your registered office if your company doesn’t occupy it. Get this in writing (email or letter on letterhead is fine) and file it with your company records. If a professional services firm or office provider is hosting your registered office, your services agreement should expressly include this consent.

3) Ensure The Address Is A Physical Australian Street Address

PO Boxes can be used for mailing, but your registered office and principal place of business must be physical street addresses in Australia. If you’re international but operating an Australian company, you will still need an Australian registered office and at least one Australian resident director.

4) Set Days And Hours For Receiving Documents

Make sure someone can receive documents at the registered office during usual business hours (for example, between 9am and 5pm on business days). If the address isn’t continuously occupied, ensure it’s open for at least a few hours on each business day and that staff know what to do if they receive formal documents. Knowing what counts as a business day can matter for deadlines.

5) Record The Address Accurately In Your Registrations

For new companies, you’ll provide your registered office and principal place of business to ASIC on registration. For existing companies, changes must be lodged with ASIC promptly.

For business name registrations (sole traders, partnerships, companies), you’ll also provide a principal place of business and a service address. Again, these must be physical Australian addresses (not a PO Box) for the principal place of business.

6) Notify ASIC Of Any Address Changes On Time

If you change your registered office or principal place of business, you must notify ASIC, generally within 28 days. Late changes can attract fees. You can update details online, but traditionally this change was made using ASIC’s Form 484-see our explainer on ASIC Form 484 to understand what’s involved and how timing works.

7) Put Internal Processes In Place

Nominate one person to monitor mail and official communications, keep a log of what’s received, and escalate legal notices immediately. Where you use a third-party address provider, ensure your service agreement includes timely scanning/forwarding of official mail and a backup contact method.

Compliance Tips: Display, Access Hours And Receiving Documents

Once your registered address is in place, maintaining compliance is straightforward if you’re organised. Here are key points to keep in mind.

Keep Your Details Current

• Update ASIC as soon as your registered office or principal place of business changes. Delays create risks and can lead to penalties.
• Review your public-facing materials (website footer, invoices, terms) for consistency after a change.

Make Sure Someone Can Receive Documents

• During your stated hours, ensure the registered office can receive hand-delivered documents and sign acknowledgements if needed.
• Train reception or front-of-house staff to recognise legal documents (for example, court documents, statutory notices) and escalate immediately.

Consider Where Your Team Actually Works

• If your team is mostly remote, it may be safer to use a professional registered office so important documents don’t go unnoticed at an underused site.
• If you operate from a shared space, it’s wise to have a formal Property Licence Agreement that confirms your address usage and mail procedures.

Protect Privacy Where Appropriate

• Using a home address is legal, but many owners prefer a professional address to keep their residential details off public records. Our guide on using residential addresses covers this in detail.
• If your registered office is publicly listed, keep your postal address separate (for example, a PO Box) for general mail if you want to limit who shows up at your premises.

Don’t Forget Governance Housekeeping

• Board minutes or founder notes should record address decisions and any consent obtained from an occupier. This creates a clear audit trail.
• If your constitution or shareholders set internal rules about office locations or records, make sure your decisions are consistent with your Company Constitution and any Shareholders Agreement you may have in place.

Common Questions About Registered Addresses

Can My Registered Office Be A PO Box?

No. Your registered office must be a physical street address in Australia so documents can be delivered and served. You can still nominate a separate PO Box for mailing.

What If I Don’t Occupy The Premises?

You need the occupier’s consent to use the address as your registered office. Get this in writing and keep it with your company records. If you’re using a professional address service or your accountant’s office, your engagement letter should include that consent and outline mail-handling arrangements.

What If We Move And Forget To Update ASIC?

Not ideal. Documents can still be served at your last recorded registered office, which means you could miss a critical notice and deadlines might run without your knowledge. You may also face late fees. Put an internal reminder in your calendar to lodge changes promptly via ASIC (see how changes are handled under Form 484 processes and the current online portal).

Can I Use A Virtual Office Provider?

Yes, if it’s a physical Australian street address and the provider gives written consent and reliably receives documents during business hours. Review the service carefully-avoid “mail only” products that don’t accommodate hand-served documents.

Does The Registered Office Need Signage?

Companies must display their name at places open to the public where they carry on business, and include required company details on documents and public materials. Whether you display signage at a serviced office depends on how you operate-but ensure your business name and ACN/ABN are used correctly on your stationery and digital channels.

Is This The Same As A Director’s Address?

No. Directors provide their own address details to ASIC separately. Your company’s registered office is the company’s legal address. If you’re thinking about privacy and address strategy for founders and officers, it’s worth planning this alongside your broader governance and resident director obligations.

What If We Operate Entirely Online?

You still need a physical registered office in Australia. Consider a suitable professional address arrangement and ensure service-of-document procedures are robust, even if your team is distributed.

Address Strategy For Growing Businesses

Your address decisions can evolve with your business. Early on, a home or co-working address might make sense. As you scale, a dedicated head office or professional registered office service can reduce risk and keep legal mail separate from day-to-day operations.

If you’re bringing on investors or restructuring, align your records across your ASIC profile, key contracts and governance documents. Address changes are a good moment to confirm wider housekeeping, such as your board details, share registers and execution procedures under section 127 (and, where relevant, updates to your Company Constitution or related governance policies).

If you operate from premises you don’t lease exclusively, consider formalising occupancy terms. A short-form licence for shared or flexible space can clarify mail handling, signage and access-your Property Licence Agreement is the right tool here.

Key Takeaways

• Your registered office is your company’s official legal address in Australia-it must be a physical street address where documents can be served.
• Registered office, principal place of business and postal address each serve different purposes; keep them accurate and consistent across your records.
• You can use a home, serviced or co-working address if it’s a street address and you have the occupier’s consent-balance privacy and practicality.
• Set up reliable processes so someone can receive and escalate legal documents during business hours; missed notices can lead to real risk.
• Notify ASIC promptly when addresses change (generally within 28 days) and align updates across your registrations and internal governance.
• As you grow, revisit your address strategy, formalise occupancy arrangements where needed, and ensure your governance (including your Company Constitution) and shareholder arrangements support the changes.
