6 Best B2B Databases for Australia in 2026 (Local Data That Actually Works)

TL;DR

• Best for ANZ contact accuracy: Firmable — purpose-built for Australia and NZ, highest mobile number hit rates
• Best for company data depth: KnowFirst — ABN and ASIC-verified, Australia's largest business database
• Best for signal-driven outreach: SyncGTM — waterfall enrichment with buying signals across your ANZ target accounts
• Best free tier: Apollo.io — Australian records with free plan; thinner ANZ coverage than local providers
• Best enterprise option: ZoomInfo — global scale but inconsistent for Australian SME direct dials

Why Australian B2B Data Is Hard to Get Right

The Australian B2B market is well-developed but small relative to the US and European markets that global data providers prioritize. That asymmetry creates a consistent problem: global databases like ZoomInfo and Apollo collect Australian business contacts, but refresh cycles are slower and coverage density — particularly for direct mobile numbers — is thinner than what they deliver for North American accounts.

Mobile numbers are the specific pain point. Australian decision-makers' direct mobiles don't appear in the same public registries that US providers rely on for phone data. Local providers that build their Australian databases through proprietary collection methods consistently produce better mobile hit rates than global providers adapting US data collection techniques.

ABN verification is the other differentiator. Australia's Australian Business Register provides a ground-truth source for company legitimacy that global databases don't always incorporate. Local providers built on ABN data give you higher confidence that you're targeting real, active businesses.

1. SyncGTM

SyncGTM is the strongest option for GTM teams targeting Australia who need more than static contact data. Waterfall enrichment cascades across 50+ providers — including ANZ-specific sources — to maximize fill rates for Australian contacts. When one provider doesn't have a mobile number, the next in the cascade is tried automatically.

The buying signals layer is what separates SyncGTM from pure data providers. Instead of just having a list of Australian companies, SyncGTM monitors your target account list for hiring surges, funding rounds, leadership changes, and job postings — so you reach them when they're actually evaluating solutions.

• Waterfall enrichment across 50+ providers for higher ANZ fill rates
• Buying signal monitoring: funding, hiring, job changes across target accounts
• Native HubSpot and Salesforce integration
• Free tier available — no credit card required
• Starting price: $99/mo

2. Firmable

Firmable is the gold standard for ANZ contact accuracy. Built specifically for Australia and New Zealand, it produces consistently better direct dial and mobile number hit rates than any global provider for ANZ contacts.

The local-first sourcing approach — collecting data through ANZ-specific channels rather than adapting global US databases — produces the higher mobile number coverage that matters for Australian outbound. For teams whose ICP is the Australian market, Firmable delivers better connected call rates per outreach sequence than global competitors.

• Highest ANZ mobile number accuracy — purpose-built local data sourcing
• Both Australia and New Zealand coverage
• Australian Privacy Act compliant data practices
• HubSpot and Salesforce integrations
• Starting price: Custom — contact for pricing

3. KnowFirst

KnowFirst claims the title of Australia's largest B2B business database. Its foundation is registry-level data — ABN-verified company records and ASIC-sourced director and officer information — which gives it better accuracy for company existence and leadership data than scraped databases.

KnowFirst is strongest for company-level intelligence and director data. For personal email and mobile enrichment, it's competitive but not always the best single source. It works well as the company data layer in a waterfall enrichment stack.

• ABN-verified company records — best company data accuracy in Australia
• ASIC director and officer data
• Financial indicators and ANZSIC industry classifications
• Australia-only coverage — no NZ or international data
• Starting price: Custom — contact for pricing

4. Apollo.io

Apollo.io is the most accessible global database with Australian coverage. The free plan gives you 50 email credits per month to test contact quality before committing. For Australian enterprise and large mid-market companies, Apollo's coverage is reasonable.

The coverage gap is direct dials for Australian SMEs. Apollo's mobile number hit rates for Australian contacts are noticeably lower than Firmable's. If your Australian ICP skews toward smaller businesses, expect more empty fields and lower connected rates on Apollo.

• Large global database with Australian records
• Free plan with 50 email credits/mo
• Sequence automation built in
• ANZ direct dial coverage weaker than local-first providers
• Starting price: $49/mo

5. ZoomInfo

ZoomInfo is the largest B2B contact database globally. Australian coverage exists but is inconsistent — enterprise company contacts are generally solid; SME direct dials are thin. The pricing model ($15k+/yr) makes it difficult to justify for Australian-market-only use cases.

ZoomInfo makes sense for enterprise teams that need global coverage including Australia as one region among many. For teams whose primary or sole market is Australia, the price-to-local-accuracy ratio doesn't compare favorably to local-first alternatives.

• Largest global B2B database — Australian records included
• Intent data via Bombora integration
• Enterprise contracts only — minimum ~$15k/yr
• ANZ SME coverage inconsistent
• Starting price: $15k+/yr

6. Lusha

Lusha is a quick-lookup tool via Chrome extension — good for individual SDRs who need to quickly find a contact's phone number while on a LinkedIn profile. Australian direct dials are hit-or-miss, and for high-volume Australian outbound, the per-credit model becomes expensive quickly.

• Chrome extension for quick LinkedIn contact lookups
• Free tier: 50 credits/mo
• Australian mobile numbers limited compared to local providers
• Better for ad-hoc lookups than systematic list building
• Starting price: $49/mo

Side-by-Side Comparison

How to Choose

The right choice depends on what you're optimizing for:

• Highest ANZ contact accuracy: Firmable for local-first mobile numbers and emails.
• Best company-level data: KnowFirst for ABN-verified company and director records.
• Signal-driven outreach: SyncGTM for waterfall enrichment plus buying signal monitoring across your ANZ target list.
• Budget-constrained with free tier: Apollo.io — acceptable ANZ coverage at no upfront cost.
• Global database with ANZ included: ZoomInfo — only justified if Australian market is one region among many for your GTM.

For most Australian-market GTM teams, the highest-value stack is Firmable or KnowFirst for local data accuracy, combined with SyncGTM for signal monitoring and CRM delivery automation. Relying on a single US-centric global database for Australian outbound is the most common reason teams see poor connected call rates in the ANZ market.
