Thirty days’ notice, on either billing term. For a registered office, the change back to your own address is lodged with ASIC as part of closing the service.

Address services

Registered office and virtual office addresses

A registered office and business address at our own staffed premises in Adelaide, available to companies registered anywhere in Australia. Mail and ASIC notices are opened, scanned and emailed to you the day they arrive.

The difference between the two services

The two are often confused. A registered office is a legal obligation under the Corporations Act and sits on the public ASIC record. A virtual office is a commercial address for your correspondence and published material. You can take either, or both at the same address.

Billing

Billed annually, inc. GST

Registered office address

$790/yr

Your company’s official address on the ASIC register, as required by section 142 of the Corporations Act.

✓Our address becomes your registered office on the public ASIC record
✓We lodge the change of registered office with ASIC on Form 484
✓ASIC notices and legal documents received, scanned and forwarded same day
✓Written occupier’s consent provided
✓A physical Australian street address, as the Corporations Act requires
✓Available to proprietary companies

Virtual office address

$790/yr

A business address for your correspondence and published material, kept separate from your ASIC record.

✓A commercial address for your website, letterhead and business cards
✓Use it as your business or mailing address for general correspondence
✓Mail received, scanned and forwarded to you
✓Available to companies, trusts, partnerships and sole traders
✓Your operating address stays private
✓Not lodged with ASIC as your registered office

Both services together

Registered office and virtual office at the one address for $1,100/yr, which is $480/yr less than taking the two separately. Your ASIC record, your letterhead and your mail all point to the same place.

What every address service includes

The handling is the same either way. What separates the two services is what the address is used for, not the standard behind it.

✓A physical Australian street address at our own staffed premises, not a PO box

✓Mail and ASIC notices opened, scanned and emailed to you the day they arrive

✓Physical forwarding weekly or monthly, or held for collection, if you prefer

✓Written occupier’s consent for the appointment

✓Change of registered office lodged with ASIC on Form 484, for the registered office service

✓Your operating address kept private and never published

✓Annual or monthly billing, cancellable on 30 days’ notice

✓Everything visible in your client portal alongside your other orders

The address

232 Unley Road
Unley SA 5061

Our own office, staffed Monday to Friday. We do not resell mailbox space or use a serviced office operator, which is why we can give the occupier's consent in our own name and open your mail the day it arrives.

A registered office has to be a physical address in Australia, not one in the state the company happens to be registered in, so this address works for companies registered anywhere in the country.

How it works

Ordering an address service

Choose your service

Registered office, virtual office, or both, on annual or monthly billing. Every address service uses our Unley premises, so there is nothing to choose on location.

Give us the entity and mail details

Entity name and ACN, your current registered office if we are replacing one, how you would like mail handled, and where forwarded mail should go. About five minutes.

We verify and lodge

We complete the AML customer due diligence, issue our written occupier’s consent, and lodge the change of registered office with ASIC. Same-day lodgement on business days.

Mail handling begins

From the day the address goes live we open, scan and email everything addressed to you on the day it arrives, so nothing waits on a postal round trip.

For accounting and legal firms

Our address for your clients, not your own premises

Holding a client's registered office has been a designated service under the AML/CTF regime since 1 July 2026, and it is a continuing one rather than a one-off. A lot of practices have decided they do not want that obligation for something they were mostly providing for free. The usual answer is to refer the client to us. We contract with the client, we provide the address, and we carry the due diligence and the monitoring. Your firm stays the adviser and stops being the address of record.

The regulated service sits with us

Your client contracts with us for the address and we provide it, which makes us the reporting entity for that service. We carry the customer due diligence, the ongoing monitoring and the records that go with it. Your firm is not the one providing the designated service, so it does not have to bring the address into your own AML/CTF program.

Your client verifies once, with us

Worth setting expectations on, because no arrangement removes it. Since we are the reporting entity we have to identify and verify the client entity and its beneficial owners before the address goes live. We run that step and it happens once. If your firm has already verified the client and would rather they were not asked twice, a reliance arrangement can cover it.

Your firm’s address comes off the register

Many firms let clients use the practice address as their registered office. It works until a client leaves, or a process server attends, or a demand arrives for an entity the firm stopped acting for two years ago. Moving those addresses removes an exposure that is easy to overlook.

Your clients do not have to publish a home address

A sole director operating from home does not want their residential address on a public ASIC search. Handing the address back and telling the client to nominate their own solves the firm’s problem by creating one for the client. This is the alternative.

Mail routed the way your firm works

Scanned correspondence can go to your firm, to the client, or to both. Firms that manage the compliance themselves usually want everything routed to them. Firms that only want to hear when something needs action take the exceptions instead.

You keep the relationship

The client is still your client. You introduce them, you stay the adviser, and we work behind your firm. We do not market to the clients you introduce, and that commitment sits in our engagement terms rather than just in a conversation.

Moving a book of addresses

Tell us how many client entities you have in mind and how you want mail routed, and we will come back with volume rates and a firm agreement covering rates and routing, with each client contracting for their own address. For one or two entities the standard order form is quicker.

Some firms would rather contract with their clients directly and bill the address under their own brand, and we can supply on that basis. Be aware it may put your firm back in the position of providing the designated service, which is usually the opposite of what firms come to us for, so take your own advice before choosing it.

Accounting firms and legal firms usually pair address services with our ASIC compliance models and, for foreign-owned clients, our resident director service.

Address services and the AML/CTF rules

Providing a registered office or business address is a designated service under Australia's AML/CTF regime, so customer due diligence is required before an address goes live. Where a customer is not covered by an AML/CTF reliance arrangement, CoSec Partners performs the customer due diligence itself and a one-off AML/KYC Screening Fee (from $150 + GST ($165)) is added to the order. Where your accounting or legal firm has already verified you and has a reliance arrangement with us, we use theirs and you are not asked again.

Common questions

What is the difference between a registered office and a virtual office?

A registered office is a statutory requirement. Under section 142 of the Corporations Act every Australian company must have a registered office, and that address appears on the public ASIC register as the place where notices and legal documents are served. A virtual office is a commercial business address used for your website, letterhead, cards and everyday correspondence. It is not lodged with ASIC. Many clients take both so the ASIC record and the published address match.

Can I use a PO box as my registered office?

No. A registered office must be a physical street address in Australia where documents can be served in person during business hours. ASIC will not accept a PO box. Our Unley address is staffed commercial premises, which is why it qualifies.

Does the registered office have to be in the same state as my company?

No. The Corporations Act requires the registered office to be a physical address in Australia where documents can be served. It does not have to be in the state the company is registered in. We provide address services from our Unley premises in Adelaide and act as registered office for companies registered in every state and territory.

Is the registered office service available to public companies?

Our standard registered office service is for proprietary companies. A public company must keep its registered office open to the public for set hours on each business day, which is a different service. Contact us and we will tell you whether we can help.

What happens to mail that arrives for me?

By default we open it, scan it and email it the day it arrives, which is what almost every client chooses. You can instead have the physical mail forwarded weekly or monthly, or held for collection.

Do I need to provide identification?

Yes. Registered office and virtual office services are designated services under the AML/CTF regime, so customer due diligence is mandatory for every customer. Where your accounting or legal firm is a reporting entity that has already verified you, we can rely on their due diligence instead of repeating it.

How do I cancel?

Thirty days’ notice, on either billing term. For a registered office we lodge the change back to your own address with ASIC as part of closing the service, so the register is never left pointing at an address you no longer hold.
