10 Best B2B Database and Contact Data Providers in Australia (2026)

The best B2B database for Australia depends on one question: is Australia your primary market, or one region in a global motion? If Australia is the market, a locally sourced database with ABN verified company records and native Australian mobile coverage beats every global platform on the numbers that matter for outbound, which are connect rate and bounce rate. If Australia is one region among several, a global platform with acceptable Australian depth is the practical choice, usually paired with a local source for phone data.

This guide compares the 10 B2B database and contact data providers most relevant to Australian outbound teams in 2026, on Australian coverage, mobile and direct dial quality, compliance posture, pricing model and best fit. It is written for sales leaders, founders and SDR managers building or buying lists, and for anyone deciding whether to buy data or buy a managed outbound service. If that second question is yours, read our companion piece on data brokers vs managed services vs SDR agencies.

TLDR

• Australia only ICP. Start with a local provider (Firmable) and supplement with LinkedIn Sales Navigator for account research.
• Global motion including Australia. ZoomInfo, Cognism or SMARTe, plus a local source for Australian mobiles.
• Small team, small budget. Apollo for breadth and sequencing, Lusha or Kaspr for point lookups.
• Enrichment layer, not a list. Clay to orchestrate multiple sources; HubSpot Breeze if you live in HubSpot.
• Firmographic screening. D&B Hoovers for financial and structural data on Australian companies.
• Whatever you buy, verify by hand before calling senior contacts. No database is accurate enough for a cold call to a CFO without a check.

Why Australia is a hard market for global databases

Global B2B databases are built for the US market and extend outward. Three consequences for Australian users.

Mobile coverage is thin. Australian decision makers' mobile numbers do not appear in the public registries US providers rely on. Local providers that collect Australian data through proprietary methods produce materially better mobile hit rates than global platforms adapting US techniques (1).

Refresh is slower. Australia is a small market for a global vendor. Records refresh less often than US records, so titles and companies go stale faster.

Coverage drops outside Sydney and Melbourne. Apollo and similar platforms cover Australian tech hubs reasonably well and thin out fast for SMBs, regional businesses and non tech sectors (2).

Data also decays. Industry estimates put B2B contact decay around 3 percent a month as people change roles, which means a list built in January has lost a meaningful share of its accuracy by mid year regardless of source (3).

The 10 best B2B database providers for Australia

1. Firmable. Best for Australia first outbound

What it is. An Australian built B2B data platform sourced natively from the ANZ market. Every record is matched to an ABN or NZBN, the platform carries real time Do Not Call flags, and the company is ISO 27001 certified (8).

Australian coverage. Firmable's own site now cites more than 3 million company records and 25 million people records across Australia and New Zealand, up from the 1 million companies and 10 million contacts quoted in earlier materials, with Australian based support (4, 8).

Why it ranks first. In independent comparisons its Australian mobile number hit rates consistently beat Apollo, ZoomInfo and Lusha, which is the single most important variable for phone first outbound (1, 4).

Limitations. Australia first. Firmable raised a Series A in March 2026 and has expanded into the United States and Canada, but that coverage is new and unproven relative to its home market (9). If your motion is global, expect to run it alongside a global platform for now. KnowFirst is another Australian native provider worth including in a data trial (4).

Pricing. Quote based with a free trial; positioned as a local platform rather than a global enterprise contract.

Best for. Australian sales teams whose primary or only market is Australia, especially phone led teams.

2. Apollo.io. Best value for small teams and sequencing

What it is. A large global contact database bundled with email sequencing and a dialler.

Australian coverage. Reasonable for Sydney and Melbourne tech companies, thinner for SMB, regional and non tech. Mobile hit rates for Australian contacts are noticeably lower than local providers (2).

Strengths. Free tier, low entry price, sequencing built in, huge global breadth. Published pricing runs from US$49 per user per month on the Basic plan (annual billing) to US$119 on the Organization plan, with roughly 20 percent more on monthly billing (10).

Limitations. Australian data quality is inconsistent. Expect more empty phone fields and a higher bounce rate than the headline record count suggests. Note also that on Apollo a phone number costs around eight credits against one for an email, so mobile heavy Australian prospecting burns through credit allowances quickly (10).

Best for. Early stage teams that need data plus outreach tooling in one place and can tolerate more verification work.

3. ZoomInfo. Best for enterprise teams with Australia as one region

What it is. The largest global B2B database, with intent data and a broad GTM platform.

Australian coverage. Solid for enterprise company contacts, thin for SME direct dials (2).

Strengths. Global scale, intent signals, integrations, enterprise governance.

Limitations. Enterprise pricing (published comparisons cite US$15,000 plus a year) with multi year contracts and auto renewal terms that buyers frequently complain about (5, 6). Hard to justify for an Australia only use case.

Best for. Enterprise revenue teams running global motions where Australia is one of many regions.

4. Cognism. Best for phone heavy teams already using it in other markets

What it is. A B2B data provider known for human verified mobile numbers and strong European and UK coverage, with DNC screening in multiple countries.

Australian coverage. Usable for teams already on the platform, but published Australian reviews say it falls short as a standalone Australian database (7).

Strengths. Phone accuracy in its core markets. Compliance posture.

Limitations. Quote based enterprise pricing, no self serve. APAC depth trails Europe.

Best for. Phone first teams with a UK or European motion that also sell into Australia.

5. Lusha. Best for fast individual lookups

What it is. A browser extension first contact tool with a large global database and a freemium tier.

Australian coverage. Covers LinkedIn indexed profiles. Useful for point lookups, weak for building Australian account lists from scratch (7).

Strengths. Speed, simplicity, strong compliance certifications (ISO 27701, SOC 2 Type II), free plan (6).

Limitations. Cannot proactively build lists by firmographic criteria. Credit based pricing scales poorly for volume.

Best for. Individual reps and small teams enriching contacts they have already identified.

6. LinkedIn Sales Navigator. Best for account research, not contact data

What it is. LinkedIn's prospecting layer: saved searches, lead lists, buyer intent signals, and access to the most current title and company data anywhere.

Australian coverage. Excellent for who works where and what they do. Provides no verified emails or direct dials.

Strengths. Freshest role data available. Essential for ICP validation and account mapping. Our Sales Navigator playbook covers how we use it.

Limitations. Not a contact database. Must be paired with a provider that supplies phone and email.

Best for. Every outbound team, as the research layer.

7. Clay. Best for orchestrating multiple data sources

What it is. An enrichment and workflow platform that queries many data providers in sequence (waterfall enrichment) and builds lists from signals.

Australian coverage. As good as the providers you connect to it. Pairing a local phone source with global email sources inside Clay is one of the more effective set ups for Australian outbound.

Strengths. Flexibility, cost control, signal based list building.

Limitations. Requires technical set up and ongoing management. Not a database in itself.

Best for. RevOps led teams building bespoke enrichment pipelines.

8. D&B Hoovers. Best for firmographic and financial screening

What it is. Dun & Bradstreet's business database, drawing on registry and credit data.

Australian coverage. Strong firmographic and structural coverage of Australian companies with credit bureau grade identifiers. Contact level depth trails purpose built prospecting tools (7).

Best for. Enterprise teams screening Australian companies by size, structure and financial fit before building contact lists elsewhere.

9. SMARTe. Best for APAC and global breadth with Australian coverage

What it is. A global B2B data provider positioning on verified contacts across 200 plus countries with strong direct dial coverage.

Australian coverage. Built for teams that need Australia alongside the US, India, LATAM and EMEA rather than as a standalone market (4).

Best for. Global and APAC GTM teams targeting Australia as one region.

10. HubSpot Breeze Intelligence (formerly Clearbit). Best for enrichment inside HubSpot

What it is. HubSpot's native enrichment layer for inbound leads and CRM records.

Australian coverage. Good for companies with a US or European digital footprint; Australian coverage outside that overlap is limited (7).

Best for. HubSpot centric teams enriching inbound, not building outbound lists.

Comparison table

Three example stacks by budget

Most Australian outbound teams end up with two or three tools rather than one. Three configurations that work, with the reasoning.

Under $500 a month, one or two callers. Apollo on a paid seat for company coverage, email and sequencing, plus LinkedIn Sales Navigator for account research and title verification. Accept that Australian mobile coverage will be patchy and budget an hour a day for manual verification of senior contacts. Consider a trial of an Australian native platform for the top 300 accounts where mobile numbers matter most.

$500 to $2,000 a month, a small team. An Australian native platform (Firmable or KnowFirst) as the primary source for Australian accounts and mobiles, Apollo or a similar global tool for email and for accounts outside Australia, Sales Navigator for research. This is the configuration most Australian mid market sales teams should run, and it is roughly what a good outsourced SDR provider runs on your behalf.

Over $2,000 a month, RevOps led. Clay orchestrating waterfall enrichment across an Australian native platform, Cognism or ZoomInfo for global depth, and signal sources (hiring, funding, technology changes) that build lists from triggers rather than filters. Sales Navigator still sits underneath for verification. This configuration produces the best lists and needs someone to run it.

How to run a two week data trial

Every provider on this list will give you a trial or a sample. Structure it so the result is a number, not an impression.

Day 1. Pull 200 contacts from your CRM that you know are accurate: current customers' decision makers, recently closed opportunities, people you spoke to last month. Include 50 from companies with 20 to 200 staff outside Sydney and Melbourne.

Day 2. Load the same 200 into each provider you are trialling. Record the match rate on company, on title, on email, and on mobile or direct dial. Mobile match is the number that decides connect rate.

Days 3 to 5. Build a 300 account list against your ICP in each tool. Count how many accounts have at least one decision maker with a phone number. Note how long it took.

Days 6 to 10. Have a caller dial 100 numbers from each provider's list. Record wrong numbers, disconnected numbers, and connects. This is the only test that measures what you actually pay for.

Days 11 to 14. Compare cost per connected decision maker across providers, including the caller time spent on bad numbers. Choose on that number.

Australian data compliance in more depth

Three regimes touch B2B contact data in Australia, and providers vary in how well they help you comply.

Privacy Act 1988 and the Australian Privacy Principles. Govern the collection, use and disclosure of personal information. Business contact details of an individual acting in their professional capacity are personal information, so how the data was collected matters. Providers that collect from public professional sources, link records to business identifiers and exclude home addresses and sensitive attributes are easier to use compliantly. Ask any provider to describe their collection method in writing.

Do Not Call Register Act 2006. Business numbers are largely outside the Register's scope and most cannot be registered, but sole traders and very small businesses may use numbers that are, and the ACMA industry standard on identification, caller ID and calling hours applies to every telemarketing call regardless. Providers that supply DNC flags save you a washing step.

Spam Act 2003. Governs commercial email and SMS. Consent, sender identification and a functioning unsubscribe are required. A purchased email address does not come with consent. For B2B, inferred consent through conspicuous publication of a business address for the relevant purpose is narrower than most sellers assume, and the safest position is to lead with the phone and use email as a follow up to a conversation.

Our cold calling laws guide covers the practical application of all three.

Common data mistakes on Australian outbound programs

• Buying the largest database rather than the one with Australian mobiles.
• Filtering by job title keyword and calling everyone the filter returns. Titles are inconsistent; a "Head of Digital" at one firm is a "CTO" at another.
• Building a list in January and calling it until June without refreshing.
• Skipping suppressions and calling current customers.
• Treating an email export as a calling list. Five percent mobile coverage cannot support a phone first program.
• Not recording wrong numbers back into the CRM, so the same bad record is dialled again next quarter.

How to evaluate any B2B database for Australian use

Six tests before you sign.

1. Run a 200 record sample against your own CRM. Measure the match rate on mobile numbers, not emails. Emails are easy. Mobiles decide connect rates.
2. Check Australian SMB coverage, not just enterprise. Pull 50 companies with 20 to 200 staff outside Sydney and Melbourne and see how many have a decision maker with a phone number.
3. Ask how Australian data is collected and refreshed. "Global crawl" means US first. "Local collection" means the provider has invested in the market.
4. Check ABN linkage. Records tied to an ABN are far easier to deduplicate and verify than records tied to a company name string.
5. Read the contract. Multi year terms, auto renewal and credit expiry are where global platforms make their margin.
6. Confirm compliance posture. How the provider collects personal information matters under the Privacy Act. For email and SMS outreach the Spam Act applies regardless of data source. Our compliance guide covers the practical rules.

Buying data vs buying a managed list

A database gives you raw material. It does not give you a list. Turning 400,000 Australian records into 2,000 accounts that fit your ICP, with the right two contacts per account, verified numbers and a reason to call, is skilled work that takes days per campaign. Most sales teams underestimate it and end up with an expensive subscription and a half built list.

If you want the list built and called, an outsourced SDR provider does both. Ask who builds it, from what sources, and whether you own it at the end. Our ICP framework covers the list building method, and our companion post on data brokers vs managed services vs agencies covers the buy vs build decision.

How Nousu builds lists

Nousu Collective builds named account lists for every campaign from a combination of local and global sources, verified by hand for senior contacts before any call is made. Clients own the list at the end of the engagement. We do not resell data. See our lead generation service.

The bottom line

For Australian outbound, the database decision is really a phone data decision. If Australia is your market, start local and supplement globally. If Australia is one region of many, start global and supplement locally for mobiles. Whatever you choose, run the 200 record test on mobile match rate before you sign, and budget the time to turn records into a list.

Frequently asked questions

What is the best B2B database for Australia? For Australia first outbound, Firmable, an Australian built platform with ABN verified records and the strongest Australian mobile coverage in independent comparisons. For global motions including Australia, ZoomInfo, Cognism or SMARTe paired with a local phone source.

Where can I buy accurate Australian B2B contact data? Local providers such as Firmable for the strongest Australian mobile coverage; global platforms such as Apollo, ZoomInfo and Cognism for breadth; Lusha and Kaspr for point lookups. Verify a sample against your CRM on mobile match rate before buying.

Is Apollo good for Australian data? Apollo is good value and covers Sydney and Melbourne tech companies reasonably well. Its Australian mobile hit rates are noticeably lower than local providers and coverage thins for SMB, regional and non tech companies.

How quickly does B2B contact data go out of date? Industry estimates put decay around 3 percent a month as people change roles. A list built at the start of the year has lost a meaningful share of its accuracy by mid year, whatever the source.

Is it legal to buy B2B contact data in Australia? Yes, subject to the Privacy Act's rules on collecting and using personal information. Calls to business numbers follow the ACMA telemarketing standard. Email and SMS follow the Spam Act, which requires consent or an existing relationship regardless of where the data came from.

What is the best B2B data stack for an Australian sales team? For most Australian mid market teams: an Australian native platform for accounts and mobiles, a global platform such as Apollo for email and non Australian accounts, and LinkedIn Sales Navigator for research and title verification. Larger RevOps led teams add Clay to orchestrate enrichment across sources.

How should I test a B2B database before buying? Load 200 contacts you know are accurate and measure the match rate on mobile numbers, not emails. Build a 300 account ICP list and count accounts with a decision maker phone number. Then dial 100 numbers and record wrong numbers, disconnects and connects. Buy on cost per connected decision maker.
