Australia has more than two million registered sole traders. The majority work from home, and the majority use their home address as their business address often without fully thinking through what that means.
When you register a business name as a sole trader, your address goes on the ASIC public register. When you register an ABN, it is linked to that address. When you put an address on an invoice, that address is visible to every client you work with.
A virtual address is a simple, affordable way to keep your home address out of all of these places while giving your sole trader business a professional street address in Sydney or Melbourne.

Sole traders and business addresses: the basics
A sole trader is an individual who runs a business in their own name (or under a registered business name) without incorporating a separate company. It is the simplest business structure in Australia with no ASIC company registration, no separate legal entity, no directors or shareholders. Just you, your ABN, and your business.
As a sole trader, you will deal with two main address obligations:
1. Your ABN principal place of business
When you register an ABN, the Australian Business Register (ABR) asks for your principal place of business — where you conduct your business activities. Most sole traders nominate their home address. This address is associated with your ABN but is not always publicly visible in the same way as a company's ASIC address.
2. Your business name address (if you have registered a business name)
If you have registered a business name with ASIC (for example, trading as "Smith Consulting" rather than "John Smith"), ASIC holds your address as part of that registration. This address is publicly searchable via the ASIC register.
Neither of these requires a physical office. A virtual address works for both.
Why your home address is a public record
The ASIC Connect database is publicly accessible. Anyone can search for your business name or ABN and find the associated address. For sole traders who have registered a business name, this means your home address is visible to anyone with an internet connection.
This is not widely understood. Many sole traders assume their home address is private, or that only the business name appears on the register, not the address. Both assumptions are incorrect.
The ASIC register is searched by:
- Prospective clients doing due diligence on a new supplier
- Competitors researching the market
- Journalists, researchers, and marketers
- Debt collectors and process servers
- Anyone who has done business with you and wants to verify your details
For sole traders who work in home-based offices and particularly for those working in client-facing professional services having a home suburb and street address accessible to anyone who searches their business name is a meaningful privacy consideration.
A virtual address removes this exposure entirely.
What a virtual address does for sole traders
Removes your home address from public records
When you update your ASIC business name address and ABN details to a virtual address, your home address no longer appears on any public register. Searching your business name returns a commercial street address in Sydney or Melbourne.
Creates a professional presence
A commercial CBD address on your invoices, website, and email signature signals an established professional operation. For sole traders working with corporate clients, this is often worth more than the $20/month it costs.
Centralises business mail
ATO correspondence, bank statements, supplier invoices, and client letters all arrive at one managed address rather than mixing in with personal mail at home. You receive digital notifications and can manage everything through an online portal.
Separates business and personal life
Using a home address blurs the line between your business and personal life in ways that can become inconvenient: clients showing up, delivery drivers ringing the doorbell during video calls, or business mail mixed with household bills. A virtual address creates a clean separation.
Do sole traders need a registered office?
No. Sole traders do not have a registered office requirement. The registered office requirement under the Corporations Act 2001 applies only to companies (Pty Ltd and other corporate structures).
As a sole trader, your address obligations are:
- ABN principal place of business (ABR): a current, accurate address for your business
- Business name address (ASIC): required if you trade under a registered business name
- ATO correspondence address: where the ATO sends tax assessments, BAS, and other notices
A virtual address can satisfy all three. There is no requirement for a sole trader to provide occupier consent letters or to use any specific type of premises; you simply need a current, accurate address.
How to use a virtual address for your ABN
Your ABN record on the Australian Business Register can be updated at any time through the ABR website.
Step 1 — Log in to the ABR portal
Go to abr.business.gov.au and log in with your myGov credentials or your ATO business account.
Step 2 — Update your principal place of business
Navigate to your ABN record and update the principal place of business to your Space Penguin address. Note: technically, if you run your business from home, your home is your principal place of business but you can use a virtual address as your postal address for correspondence.
Step 3 — Update your postal address
The ABR distinguishes between your principal place of business (where you work) and your postal address (where you receive mail). For most sole traders, updating the postal address to a virtual address is the most practical approach, as it ensures business mail goes to the managed address while your actual operating location remains accurate.
Step 4 — Update your ASIC business name (if applicable)
If you have a registered business name, log in to ASIC Connect and update the service address to your virtual address.
Invoicing with a virtual address
Australian tax invoices do not legally require a physical address. A valid tax invoice must include:
- The words "tax invoice"
- Your business name and ABN
- The date of issue
- A brief description of the goods or services
- The amount payable and GST component
You are not legally required to put an address on an invoice. However, many businesses include one as standard practice, many clients expect it, and many accounting software templates include an address field by default.
If you include an address on your invoices, your virtual address is the right choice. It is:
- Consistent with your ABN and ASIC records
- Professional and credibility-building
- Free of any privacy risk
- Consistent across all business touchpoints
Upgrading from home address to virtual address
If you are currently registered with your home address and want to switch to a virtual address, the process is straightforward.
Step 1 — Sign up with Space Penguin
Choose your city and plan. You will receive a virtual address and occupier documentation within 24 hours.
Step 2 — Update your ABN record
Log in to the ABR and update your postal address (and principal place of business if appropriate) to your new virtual address.
Step 3 — Update your ASIC business name
If you have a registered business name, update the address in ASIC Connect.
Step 4 — Update your ATO records
Log in to MyGov and update your business address, or ask your accountant to do this through the Tax Agent Portal.
Step 5 — Update your bank
Notify your business bank of your new address, particularly if your bank account is linked to your old home address.
Step 6 — Update all client-facing materials
Website, email signature, invoices, business cards, LinkedIn, directory listings. Create a checklist and work through it systematically.
How long does the old address stay on the ASIC register?
Once you submit the update, changes to the ASIC register typically take effect within 1–2 business days. Your old address will no longer appear after the update is processed.

Frequently asked questions
I'm a sole trader but I haven't registered a business name. Do I need a virtual address?
Not for ASIC purposes — sole traders who trade under their own name (not a registered business name) do not appear on the ASIC business name register. Your ABN postal address can still benefit from a virtual address for privacy and professionalism, but it is not a public record in the same way.
Can I use a virtual address in a city I don't live in?
Yes. There is no requirement for a sole trader's business address to match their residential address or be in the same city. Many sole traders use a Sydney address while living in Brisbane, or vice versa.
Will using a virtual address affect my home office tax deduction?
No. Your home office deduction is based on the actual use of your home for work, as assessed by the ATO. The address registered with ASIC or the ABR is irrelevant to this calculation.
What about WorkCover (workers' compensation) for my sole trader business?
WorkCover policies and sole trader obligations are based on your business activities, not your registered address. Changing your address has no effect on WorkCover obligations.
If I incorporate a company later, do I need to change anything?
Yes. If you transition from sole trader to company, you will need to register the company with ASIC and provide a registered office address. You can use your existing Space Penguin virtual address for the company's registered office just update the registration to reflect the new entity.
Space Penguin provides virtual addresses for sole traders in Sydney and Melbourne from $20/month — keep your home address private and your business looking professional.
