When you’re setting up (or scaling) a company, choosing your registered address can feel like a small admin detail.
But your company’s registered address is more than a line on a form. It’s the official place where legal documents can be served, where regulators can contact you, and where certain records may need to be accessible. If you get it wrong, it can create delays, missed notices, and unnecessary compliance headaches.
In this guide, we’ll break down what a registered address is, what Australian law generally requires (including some key Corporations Act requirements founders often miss), and the practical options small businesses often use (including the pros and cons of each). We’ll also cover what to do if your address changes, and how to avoid common pitfalls.
What Is A Registered Address (And Why Does It Matter)?
Your company’s registered address (often called its “registered office”) is the official address for your company on the public record.
In practical terms, it’s the address that government agencies and third parties can use to contact the company, including for formal communications. This is why a company’s registered address is sometimes described as its “legal home base”, even if you don’t actually operate there day-to-day.
What Your Registered Address Is Used For
Your registered office address may be used for things like:
- Service of documents (for example, court documents, notices, or formal demands)
- Regulatory correspondence from ASIC and other agencies
- Public searches where suppliers, lenders, or customers look up basic company details
- Record-keeping obligations (depending on how you manage your company records and where they’re kept)
Because it’s publicly accessible, it’s also part of your business “paper trail”. If you’re trying to build trust with customers, investors, or suppliers, having a stable registered office address can help avoid confusion.
Registered Address vs Business Name Address vs Trading Address
A common source of confusion is that your company can have multiple “addresses” for different purposes.
For example, you might have:
- Registered office (registered address): the official address on ASIC’s register.
- Place of business / trading address: where you actually operate (shopfront, warehouse, studio, etc.).
- Mailing address: where you prefer day-to-day mail to go (which might be a PO Box).
These can be the same address, but they don’t have to be. What matters is that you meet the legal requirements for your registered office and keep it current.
Legal Requirements For A Company Registered Address In Australia
If you run a company in Australia, there are legal rules about having and maintaining a registered address (registered office). While the specifics can depend on your circumstances, the key principles are fairly consistent: the address must be in Australia, it must be kept up to date, and it must be a place where the company can be formally contacted.
The Registered Address Must Be In Australia
Your company’s registered address must be a physical address in Australia. In most cases, a PO Box alone won’t satisfy the requirement because it is not a physical location.
This is one reason many online-first businesses still need to decide what physical location they will use as their registered office, even if they don’t have a traditional office.
You Need Consent If It’s Not Your Own Premises
Using someone else’s address (for example, your accountant’s office, a co-working space, or a friend’s premises) requires the occupier’s consent.
Importantly, this consent should be in writing, and the company must keep that written consent with its records. This isn’t just a courtesy. It’s part of making sure you’re not listing an address you don’t have the right to use, and that the people at that address understand they may receive official correspondence for your company.
It Must Be Able To Receive Official Documents
A registered office needs to be reliable for receiving formal notices. If important correspondence goes to an old address, there’s a real risk you’ll miss time-sensitive deadlines (for example, deadlines to respond to regulatory notices or court documents).
From a risk perspective, this is one of the biggest reasons your registered office should be stable and properly monitored.
Your Registered Office Must Be Accessible
There’s also an accessibility requirement that often gets overlooked: your registered office must generally be open to the public for at least 3 hours on each business day (during normal business hours). If your registered office is not open during the standard hours, you may need to notify ASIC of the hours when it is open.
This matters for practical reasons too: service of documents and regulatory notices need to be able to reach you at that address.
It Can Affect How You Manage Your Company Setup Documents
Your registered address decision often sits alongside other foundational setup items, like who your directors and shareholders are, what rules govern the company internally, and how decisions are documented.
As you formalise your structure, documents like a Company Constitution can help clarify internal governance (including how your company handles notices and decision-making), which becomes increasingly important as you grow.
If you’re still in the setup phase, your registered address will usually be selected as part of your Company Set Up process.
What Options Do You Have For Your Registered Company Address?
There’s no one-size-fits-all solution for your registered office address. The right option depends on how you operate, whether you want your address public, and how much flexibility you need as your business grows.
Here are the most common choices we see for small businesses.
Option 1: Your Home Address
Many early-stage founders use their home address as the registered office. It’s simple, cost-effective, and usually easy to manage.
Pros:
- Low cost
- Easy to monitor mail and notices
- No need to rely on a third party
Cons:
- Your address may be publicly searchable (privacy and security concerns)
- If you move, you must update your details promptly
- It can look less “commercial” for certain industries or client bases
If privacy is a big concern, it’s worth considering whether a different registered office option is more suitable for your situation.
Option 2: Your Business Premises (Shop, Office, Warehouse)
If you lease or own business premises, using that address can be a neat and straightforward solution.
Pros:
- Clear connection to the business operations
- Usually staffed during business hours
- Can look professional for suppliers and customers
Cons:
- If you relocate, you must update ASIC details
- If the premises aren’t consistently staffed (or not open to the public for the required hours), you might miss important deliveries
- If the lease ends suddenly, your registered office can become outdated quickly
One practical tip: if your business premises change frequently (for example, you’re scaling quickly or moving between short-term spaces), you may want a more stable registered office arrangement.
Option 3: Your Accountant, Bookkeeper, Or Lawyer’s Address
Some businesses use the address of their accountant or lawyer as their registered office, with consent.
Pros:
- Stable address even if you move or change premises
- Professional handling of official mail
- Can reduce the chance of missing important notices
Cons:
- Ongoing fees may apply
- You’re relying on a third party to pass on mail promptly
- If your relationship ends, you may need to update your registered office quickly
If you do use a third-party address, you’ll want a clear process for forwarding mail and handling urgent documents (especially anything that looks like a formal notice).
Option 4: A Virtual Office Or Co-Working Space
Virtual office and co-working providers often offer a physical address that can be used as a registered office (subject to their terms and consent arrangements).
Pros:
- Good privacy option if you don’t want your home address public
- Can support a professional image
- May include mail handling services
Cons:
- There’s a cost
- Not all providers allow their address to be used as a registered office (or they may have restrictions)
- Mail handling quality and speed varies, which can be a real issue for urgent legal documents
If you’re considering this option, make sure you understand exactly what the provider will do if formal documents are delivered, how quickly you’ll be notified, and whether the premises will meet the accessibility requirements (for example, being open to the public for the required hours).
Option 5: Separate Addresses For Registered Office And Day-To-Day Mail
Some businesses choose a stable registered office address for compliance and a separate mailing address for convenience.
This can work well if:
- you move around frequently (for example, project-based businesses), or
- you don’t have a staffed office, but you still want a stable registered office.
Just make sure you’re not accidentally letting official correspondence go to an address that isn’t being monitored.
How Your Registered Address Fits Into Your Wider Business Setup
It’s easy to think of your registered office as “just admin”, but it connects to your broader compliance and risk management.
If You’re Registering A Business Name
Many founders register a business name and later decide to incorporate, or they do both around the same time.
Even if your brand and website say one thing, your official records can say another. Making sure your public-facing details align with your structure can prevent confusion, especially when you’re dealing with invoices, suppliers, or funding.
If you’re at that stage, the Business Name registration side and your company registration details should work together (rather than pulling in different directions).
If You Have Co-Founders Or Investors
If you’re running a company with other people, you’ll usually want clarity around who controls what, how decisions are made, and what happens if someone wants to exit.
These issues aren’t “address” issues, but they often come up at the same time as company setup details like your registered office, share structure, and record keeping.
A tailored Shareholders Agreement can help set expectations early and reduce the risk of disputes later, especially as the business grows and responsibilities shift.
If You Run An Online Business (Privacy, Terms, And Customer Trust)
If you sell online or collect customer data, your compliance footprint extends beyond ASIC records. Your legal “front door” is often your website, checkout flow, and the policies you publish.
In many cases, you’ll want a Privacy Policy (especially if you collect personal information), and Website Terms and Conditions to set expectations around your site use, orders, limitations, and processes.
While these documents don’t replace your registered office obligations, they work alongside them to help your business look professional and reduce avoidable disputes.
If You’re Hiring Staff
If your company is employing people, there are extra compliance considerations (and more paperwork). Even if your registered office is handled neatly, employment issues can create risk if not set up properly from day one.
Having a clear Employment Contract helps document key terms like duties, pay, confidentiality, and termination arrangements, so everyone knows where they stand.
How Do You Change Your Registered Address (And When Should You Do It)?
Businesses change locations all the time. You might start from home, move into a co-working space, then take on a lease, then move again as you grow.
The key is making sure your registered office is updated promptly, so you don’t miss important notices.
Common Triggers For Updating Your Registered Address
- You move house (and your home address was your registered office)
- You change office or shop premises
- Your virtual office / mail handling arrangement ends
- Your accountant or advisor stops providing address services
- You restructure your business operations and want a more stable registered office
When Do You Need To Notify ASIC?
Generally, when your registered office changes (or the office hours change, if you’ve notified ASIC of specific hours), you need to notify ASIC within 28 days. This is commonly done by lodging a change to company details (often via Form 484, or online through ASIC’s portal).
Practical Tips To Avoid Missed Notices
- Update early: don’t wait until the last minute or after the move is complete.
- Keep proof of consent: if you use a third-party address, keep written confirmation on file.
- Set up internal processes: decide who is responsible for checking mail and escalating urgent items.
- Don’t confuse addresses: keep track of which address is the registered office, and which is a mailing address.
If your business has multiple directors or someone else handles admin, it’s also worth clarifying who has authority to make changes to company details and lodge forms. In some situations, having an Authority to Act Form can help document who is authorised to act on behalf of the business for specific tasks.
Common Mistakes Small Businesses Make With Their Registered Address
Most registered office problems don’t come from bad intentions. They usually come from moving fast, delegating admin, or assuming an address “doesn’t really matter”.
Here are some common issues to watch for.
1. Using An Address Without Proper Consent
Listing an address you don’t have permission to use can create legal and practical issues, especially if the occupier asks you to remove it or refuses deliveries.
Always obtain clear consent first, make sure it’s in writing, and confirm whether the address provider has any conditions (for example, mail forwarding fees, restrictions on accepting service of documents, or requirements about office access/hours).
2. Treating A PO Box As A Full Replacement
A PO Box is helpful for mail management, but it won’t satisfy the requirement for a physical registered office address.
Where a PO Box is used, it’s usually best as a separate mailing address - not as the only address on record.
3. Forgetting To Update After Moving
This is one of the biggest risks because it can be silent for months, then become a problem when a time-sensitive notice is served to an old address.
If you’re moving premises, add “update registered office with ASIC (within 28 days)” to your relocation checklist right alongside redirecting mail and updating your website footer.
4. Choosing An Address You Don’t Monitor
It’s not enough for an address to exist on paper. It needs to be monitored in real life.
If you use a third-party registered office address, make sure you know:
- who will receive mail on your behalf
- how quickly they notify you
- what happens if something looks urgent or legal in nature
- whether the address will be open and accessible as required
5. Overlooking The Privacy Angle
Because a company’s registered office address can be publicly searchable, using your home address can raise privacy concerns (particularly for founders running online businesses or operating from home long-term).
If that’s you, it may be worth weighing up a more private option, even if it costs a bit more.
Key Takeaways
- Your registered address (registered office) is the official company address on the public record and is used for formal notices and service of documents.
- Your registered office generally needs to be a physical address in Australia, and you typically need written occupier consent if it’s not your own premises (which should be kept on file).
- Your registered office usually must be open to the public for at least 3 hours each business day (and you may need to notify ASIC of different office hours where applicable).
- Common options include your home address, your business premises, an accountant/lawyer’s address, or a virtual office - each has different privacy, cost, and reliability trade-offs.
- If your registered office changes, you generally need to notify ASIC within 28 days (commonly via Form 484 or an online update), to avoid missed deadlines and compliance issues.
