Registered Office in Australia: Who Needs One and How to Set It Up

When you register a company in Australia, one of the first details you’ll be asked for is a “registered office.” It sounds simple, but getting this right matters - it’s where official notices and legal documents can be served on your company, and it’s a detail that appears on public records.

If you’re a small business owner planning to incorporate, or you already run a company and you’re moving premises, this guide breaks down exactly what a registered office is, who needs one, the legal requirements, and the practical steps to set it up (or change it) without stress.

We’ll also share tips to avoid common mistakes and explain how your registered office fits with other core company details, so your business is compliant from day one.

What Is A Registered Office (And Why It Matters)?

Your registered office is the official address of your company on the ASIC register. It’s the address for service of legal documents, notices from regulators (including ASIC and the ATO), and other formal correspondence.

This address is public. Anyone searching your company can see it. That’s why many founders think carefully about privacy and mail handling when choosing a registered office.

Importantly, your registered office is not always the same as your “principal place of business.” Your principal place of business is where you actually carry out operations (for example, your store, studio, or warehouse). Your registered office is where documents can formally be delivered to the company - and it has its own legal rules.

Do You Need A Registered Office For Your Small Business?

All Australian companies (both proprietary (Pty Ltd) and public companies) must have a registered office in Australia. If you’re operating as a sole trader or partnership, the “registered office” concept doesn’t apply - although you still need an ABN and a principal place of business.

If you’re in the early stages and weighing structures, a company can provide limited liability and a more professional footing as you grow. As part of that setup, you’ll nominate your registered office when you set up a company.

Companies also need at least one director who ordinarily resides in Australia, which often influences where you choose to locate your registered office. If you’re not sure how the residency rules work for directors, it’s worth reading up on Australian resident director requirements.

Registered Office Requirements Under Australian Law

The Corporations Act sets out several practical requirements for a company’s registered office. In short, the address must be suitable for receiving formal documents, and ASIC needs to know where and when documents can be delivered.

1) The Address Must Be In Australia (And Physical)

Your registered office must be a street address in Australia. A PO Box isn’t acceptable for the registered office. If you use a third party’s address (for example, an accountant’s office or a serviced office), you’ll need their written consent.

2) Hours Of Availability

Your registered office must be open during certain times so documents can be delivered:

• Public companies: Open to the public between at least 10am and 12pm and 2pm and 4pm each business day (or other hours totaling at least three hours between 9am and 5pm).
• Proprietary companies (most small businesses): Must be capable of receiving documents. If it’s not occupied during normal business hours, you’ll need to notify ASIC of the hours when it is open and able to accept documents.

Many small companies use a location with reliable reception and mail handling to ensure nothing is missed.

3) Consent Of The Occupier

If the company does not occupy the premises, the occupier must provide written consent to use the address as your registered office. Keep a copy with your company records. You may also need to display the company’s name at the premises if the location is open to the public.

4) Keep ASIC Updated

If your registered office address or office hours change, you must notify ASIC within 28 days. Late changes can attract fees and create risk if important documents go to the wrong place.

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

Yes, you can use a residential address as your registered office, as long as it meets the requirements above. This is common for early-stage companies, but do think about privacy and the fact that the address appears on public records. If you’re considering this approach, check the practical tips in our guide to using residential addresses for company registration.

A serviced or “virtual office” can also work well, provided it is a physical Australian address, can accept documents, and the occupier gives written consent. If you’re licensing a space in a co-working hub, ensure your arrangement clearly permits use of the address as a registered office - a simple Property Licence Agreement can make roles and responsibilities clear.

Two quick caveats:

• PO Boxes are not suitable as a registered office.
• Overseas addresses are not acceptable - the registered office must be in Australia, even if directors live overseas.

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

If you’re starting fresh or moving premises, here’s a simple process that aligns with ASIC’s requirements and best practice for small companies.

Step 1: Choose A Suitable Address

Pick a physical address in Australia where documents can be reliably received. Consider who will manage incoming mail (and how quickly important notices will reach decision-makers). If you don’t occupy the premises, arrange written consent from the occupier.

Step 2: Set It During Company Registration (New Companies)

When you apply to register a company, you’ll provide your registered office address as part of the standard application. If you’re working through the details now, we can help you get it right with a streamlined company setup process.

Step 3: Notify ASIC Of Any Changes (Existing Companies)

Already registered and moving? Notify ASIC within 28 days. You can lodge the change online. For many company detail updates, you’ll be guided through the equivalent of the old Form 484 process - our overview of ASIC Form 484 explains how these changes work in practice.

Step 4: Confirm Office Hours

Ensure your registered office is available during business hours. If the premises isn’t normally occupied, notify ASIC of the specific hours when documents can be served. Keep these hours consistent and ensure someone is responsible for receiving documents.

Step 5: Put Mail Handling Processes In Place

Nominate a contact person to check mail at least weekly. For critical correspondence (like ASIC notices), build a simple rule: scan and forward to the directors and your registered email the day it arrives, and diary any response deadlines.

Step 6: Update Your Company Details Everywhere

Once your registered office changes, update your details across business documents and platforms - website footers, letterheads, invoices, contracts, your bank, insurance policies, and other registrations. Consistency reduces confusion and missed mail.

Step 7: Record A Board Decision

It’s good governance to minute the change and keep it with your company records. If you need a simple board sign-off, a Directors Resolution Template can help you document decisions properly.

Practical Tips To Manage Your Registered Office

Beyond the legal basics, a few practical habits can save headaches:

• Use a reliable address. Choose a location where someone is present to receive documents during office hours.
• Build a mail routine. Set a regular schedule to collect, scan, and escalate critical letters.
• Keep written consent handy. If your company doesn’t occupy the premises, store the occupier’s consent with your records.
• Know what’s public. Your registered office appears on ASIC’s public register - pick an address you’re comfortable disclosing.
• Separate roles. Your registered office can be different from your principal place of business - and that’s often a smart way to manage privacy and logistics.
• Check signage obligations. If the premises is open to the public, ensure your company name is displayed as required.

If you’re setting broader governance foundations at the same time, consider adopting a clear Company Constitution and documenting roles between founders. These steps sit neatly alongside your registered office setup and keep your company records in order.

Common Pitfalls (And How To Avoid Them)

We regularly see the same issues crop up around registered offices. Here’s how to steer clear of them.

• Using a PO Box. A PO Box isn’t acceptable as a registered office. Use a physical street address in Australia.
• Forgetting occupier consent. If the address isn’t your own premises, you need written consent. Don’t skip this - it’s a Corporations Act requirement.
• Moving without telling ASIC. You must notify ASIC within 28 days of any change. Missing this window can mean late fees and misdirected legal notices.
• Unclear office hours. Make sure documents can be received during business hours, and if the premises isn’t usually occupied, notify ASIC of the hours when it is.
• Mixing up company details. Your company’s registered office and principal place of business are different details - and both are different again from a registered business name. If you’re unsure about the distinctions, this explainer on Business Name vs Company Name is a helpful refresher.
• Poor mail handling. Important notices (like compliance reminders or statutory demands) can have strict deadlines. Have a named person who checks mail and escalates anything urgent immediately.

What Other Company Details Should You Get Right From Day One?

Your registered office is part of a bigger compliance picture. A few other “foundation” details to finalise early include:

• Constitution and governance. Adopting a tailored Company Constitution helps set decision-making rules and process for your board.
• Founder alignment. If there’s more than one owner, a Shareholders Agreement clarifies equity, roles, exits, and how disputes are resolved.
• Signing rules. Decide who can bind the company on contracts and make sure you understand signing under section 127 so execution of documents is valid and efficient.
• Director residency and records. Confirm you meet director residency requirements and keep core company records (like minutes and registers) at your registered office or at another nominated place.

These steps sit alongside your registered office obligations and give your company a clean, compliant foundation to grow from.

Key Takeaways

• A registered office is the company’s official address for service of documents and must be a physical address in Australia (not a PO Box).
• All companies need a registered office; sole traders and partnerships don’t - but if you incorporate, you’ll set this when you register the company.
• If you don’t occupy the premises, get written consent from the occupier and ensure the office can receive documents during business hours.
• Home and serviced offices can work as registered offices, but consider privacy and make sure mail handling is reliable.
• Notify ASIC within 28 days of any change to your registered office address or hours to avoid penalties and missed notices.
• Tie your registered office setup into broader governance - things like your Constitution, Shareholders Agreement, and signing rules help keep everything consistent and compliant.
