Australia is the quiet success story of open business data. ABN Lookup is free, comprehensive, machine-readable and almost nobody outside accounting uses it for prospecting.
This is one of a set of country guides. The overview of how to read any directory is here, and the others are the USA, the UK, Canada and the UAE.
The layers, ranked
| Source | Type | Contact details | Freshness | Best for |
|---|---|---|---|---|
| ABN Lookup | Official register | No | Very high | Verification, entity type, GST, state |
| Live map data | Listing | Phone, website, hours | Very high | Local and service businesses |
| ASIC registers | Official register | Registered office | Very high | Company officers, filing history |
| Yellow Pages Australia | Legacy listing site | Phone, website | Medium to high | Broad coverage across trades |
| Trade platforms | Vetted marketplace | Phone, website | High | Home services and trades |
| Industry associations | Member list | Often a named person | High | B2B into a defined industry |
| State chambers | Member list | Phone, website | High | Local B2B by state |
| Review platforms | Review site | Phone, website | High | Trust-led categories |
1. ABN Lookup
Run by the Australian Business Register, this covers every entity holding an Australian Business Number, which is effectively every business trading in Australia including sole traders, partnerships and trusts. It is free, searchable on the web, available through a web service, and published as bulk extract files.
What it gives you:
- Legal entity name and trading names. The trading name is often what appears on the shopfront, and the legal name is what appears nowhere.
- Entity type. Sole trader, company, partnership, trust. This changes both your qualification and your tone.
- ABN status and registration date. Active or cancelled, and how long they have been trading.
- GST registration. A real size signal, because registration is compulsory above a turnover threshold.
- State and postcode of the main business location.
What it does not give you: any way to contact them.
Use it as: the enrichment layer over a contact list, exactly as you would use Companies House in the UK. GST status plus registration date is a fast, free qualification filter that most Australian prospecting simply does not apply.
2. Live map data
For local and service businesses this remains the strongest source, for the same reason it is everywhere: the business maintains the listing because customers use it to find them.
Australia is a heavily urbanised market with long distances between centres, which makes geographic segmentation unusually clean. "Plumbers within 20km of Geelong" is a real, workable list in a way that a national list of plumbers is not.
3. ASIC registers
The Australian Securities and Investments Commission holds the company register: officeholders, registered office, filing history, and the business names register.
Narrower than ABN Lookup and deeper on companies specifically. Some searches and extracts are free and some are paid.
Use it when: you need officeholder names, or you are qualifying by corporate structure rather than by trading activity.
4. Yellow Pages Australia
The broadest general listing site, with the usual pattern: paid listings are current, free entries drift. Coverage is genuinely wide, particularly for established businesses and regional areas where map coverage thins out.
5. Trade platforms
Australia has a strong vetted-trades sector, with platforms where tradespeople pay to receive job leads and are checked before they are listed. That makes them a pre-qualified list with real contact details, and it makes the businesses on them used to being approached commercially.
Best for: anyone selling to trades, which in Australia is a large and well-defined market.
6. Industry associations and state chambers
Every industry has a national body and usually a state chapter. Member lists are small, current, and carry the same built-in qualification as everywhere: membership costs money.
Australia's state-based structure is an advantage here. A state chapter list is a naturally sized segment, and shared state membership is a genuine opening line.
The legal part, and it is stricter than you expect
The Spam Act 2003 is materially tighter than CAN-SPAM, and the difference catches people out.
It requires consent, either express or inferred. It is not a regime where "B2B is fine" is a defence.
Inferred consent is the route most B2B outreach relies on, and it is narrower than the phrase suggests. In broad terms it can arise where:
- The address is conspicuously published in a business context.
- The publication carries no statement that unsolicited commercial electronic messages are unwelcome.
- Your message is directly relevant to the role or function the address represents.
That middle condition is the one people miss. A contact page carrying "no unsolicited marketing emails" removes the inference for that address, and it is not rare on Australian sites.
You must also identify the sender accurately, including current contact details for your business, and provide a functional unsubscribe that keeps working for a period after the message is sent.
The Act covers email, SMS and instant messaging, so WhatsApp outreach into Australia sits under the same rules. Our overview of where cold email is legal has the wider picture, and none of this is legal advice.
Putting it together
- Segment by state and business type. Australia rewards geographic segmentation more than most markets.
- Harvest contacts from map data, a listing site, or a trade platform.
- Check the published page for a no-unsolicited statement before you add an address to a send list. This is the Australian-specific step and it takes seconds.
- Enrich from ABN Lookup for entity type, status and GST registration.
- Verify every address, then write something specific and follow up.
Leads Ranger runs steps 2, 4 and 5 in one workflow: live discovery harvests the businesses, verification checks every email and phone number before anything sends, and sequences handle the follow-up from your own mailboxes. The browser extension covers the directories themselves, taking businesses from any listing page straight into your pipeline in Chrome, Firefox or Edge.
