Disclosure: PhishCare is a product developed by CyberSapiens, and CyberSapiens appears in this list. Our evaluation criteria are set out below so every provider is judged on the same basis. Information about other firms comes from their own public websites as of October 2026.
Quick answer
Leading ISO 27001 consultants in Australia include CyberSapiens, CyberCX and Gridware. Leading certification bodies include BSI, Intertek SAI Global, Bureau Veritas, DNV, Global Compliance Certification, LRQA and TQCSI.
You usually need one of each: a consultant to build your ISMS, and a separate accredited certification body to audit it and issue the certificate.
ISO 27001 consultant or certification body: which do you need?
Many “top ISO 27001 companies” lists mix two very different types of firm. Accreditation rules stop a certification body from implementing the ISMS it later certifies, so the roles are kept separate.
ISO 27001 consultant
Gap analysis, risk assessment, policies, Statement of Applicability, control implementation and internal audit. Gets you ready.
Certification body
Independent Stage 1 and Stage 2 audits, the certificate itself, and annual surveillance audits.
Always check that your certification body is accredited. In Australia you can verify accreditation and certificates through JAS-ANZ, the Joint Accreditation System of Australia and New Zealand.
How we evaluated ISO 27001 providers
We assessed each provider against six criteria that matter to Australian businesses:
- Role: consulting and implementation, or independent certification.
- ISO 27001:2022 capability: current-version implementation or audit experience.
- Australian presence: local teams and coverage across states.
- Fit by company size: suitability for SMEs, mid-market or enterprise.
- Pricing transparency: published prices or a fixed-price approach.
- Related services: SOC 2, Essential Eight, APRA CPS 234 or multi-standard audits.
No firm paid to be included. Consultants are ranked by fit for Australian SMEs and scale-ups; certification bodies are listed without ranking, because the right one depends on your industry, other standards and auditor availability.

Top ISO 27001 consultants in Australia
1. Consultant
CyberSapiens
CyberSapiens is an Australian cybersecurity and compliance firm based in Port Melbourne, and the company behind PhishCare. It takes businesses from gap analysis to certificate through a four-phase programme (Assess, Build, Implement, Certify), fully remote across Australia, with Certified ISO 27001 Lead Auditors on each engagement.
- Services: gap analysis, ISMS documentation, risk assessment, internal audit, VAPT, security awareness training, SOC 2
- Published timeline: 4 to 6 months for most small and mid-sized businesses
- Published pricing: fixed price, AUD 8,000 to 20,000 for small businesses and AUD 12,000 to 30,000 for mid-sized
Consider if: you want one team for ISO 27001, SOC 2 and Essential Eight at a published price. Less suited if: you need a very large onsite team across many locations at once.

How to choose an ISO 27001 consultant in Australia
Ask every shortlisted consultant these questions:
- Will a Certified ISO 27001 Lead Auditor work on our project, and who exactly?
- Is the quote fixed, and does it include the internal audit and audit-day support?
- Which certification bodies have your clients used, and can you help us choose one?
- How much of the documentation will be tailored to us rather than templated?
- Can you align ISO 27001 with Essential Eight, SOC 2 or APRA CPS 234 at the same time?
- What support do you offer after certification for surveillance audits?
It also helps to read the standard’s own summary on the official ISO/IEC 27001:2022 page, so you can judge whether a consultant’s plan covers every requirement.
Where security awareness training fits
Whichever consultant and certification body you choose, auditors will test Annex A 6.3 on security awareness, education and training. PhishCare’s campaign reports provide an additional documentation boost for organisations working towards ISO 27001, where ongoing security awareness training is recognised as a best practice by auditors and certification bodies.

Frequently asked questions
What is the difference between an ISO 27001 consultant and a certification body?
A consultant helps you build and run your ISMS. A certification body independently audits it and issues the certificate. Accreditation rules stop a certification body from implementing the system it certifies.
How much does an ISO 27001 consultant cost in Australia?
Typical total market costs are AUD 15,000 to 35,000 for small businesses and AUD 35,000 to 80,000 for mid-sized businesses. CyberSapiens publishes fixed prices from AUD 8,000.
How do I check that a certification body is accredited in Australia?
Search the JAS-ANZ register for the certification body and for any certificate it has issued. Certificates accredited by other International Accreditation Forum members are also recognised.
Can ISO 27001 consulting be done remotely in Australia?
Yes. Gap analysis, documentation, risk workshops and internal audits can all be run remotely. Some certification bodies may still want onsite time for parts of the Stage 2 audit.
How long does it take to get ISO 27001 certified with a consultant?
Most small and mid-sized Australian businesses take 4 to 6 months from gap analysis to certificate. Large or multi-site organisations usually need longer.
