ISO 27001 Audit in Australia: Process, Certification Companies & Cybersecurity Audit Readiness

Executive Summary

Australian organisations are under increasing pressure to demonstrate information security assurance to customers, regulators, and supply chain partners. An ISO/IEC 27001 audit provides formal recognition that an organisation has implemented a fit-for-purpose Information Security Management System (ISMS), aligned with international standards and local compliance requirements.

In this guide, we explore:

• What an ISO 27001 audit involves
• The role of certification companies in Australia
• How cybersecurity audits differ from ISO 27001 audits
• Best practices to prepare for certification success
• How CyberPulse supports organisations across readiness, certification, and ongoing compliance

Why ISO 27001 Audits Matter in Australia

ISO/IEC 27001 is the global gold standard for information security management. In Australia, it plays a central role in meeting:

• Privacy Act 1988 obligations for handling personal information
• APRA CPS 234 requirements for regulated financial institutions
• ACSC Essential Eight maturity targets
• Supply chain due diligence for government and enterprise procurement

For many organisations, particularly in SaaS, financial services, healthcare, and government supply chains ISO 27001 certification is no longer optional. An independent audit provides assurance that your security program is not only designed but proven in practice.

Types of ISO 27001 Audits

1. Internal Audit
   Conducted by the organisation (or an independent consultant) to confirm readiness before certification. Identifies gaps and control weaknesses early.
2. Stage 1 Audit (Readiness Review)
   A certification body reviews policies, scope, and ISMS documentation.
3. Stage 2 Audit (Certification Audit)
   Auditors test controls in practice, interview staff, and assess risk management effectiveness.
4. Surveillance Audits
   Annual reviews by certification companies to confirm ongoing compliance.
5. Recertification Audit
   A full re-audit every three years to maintain ISO 27001 certification status.

ISO 27001 Certification Companies in Australia

Certification is only valid when issued by an accredited certification company (also called conformity assessment bodies). In Australia, recognised providers are accredited by JAS-ANZ (Joint Accreditation System of Australia and New Zealand).

Top factors when selecting a certification company:

• Accreditation – Ensure the body is JAS-ANZ accredited.
• Sector expertise – Some auditors specialise in government, financial services, or SaaS.
• Audit approach – Look for auditors that understand your operational context.
• Global recognition – Larger organisations may require certification recognised in multiple regions.

CyberPulse offers an end-to-end audit process and partners with leading certification companies and helps clients prepare for the audit, ensuring a smoother, faster path to certification success.

ISO 27001 Audit vs Cybersecurity Audit

While both ISO Audits and Cyber Audits provide assurance, they serve different purposes:

👉 Many Australian organisations choose to combine both audits: using a cybersecurity audit to test technical resilience and an ISO 27001 audit to formalise governance and certification.

ISO 27001 Audit Process: Step by Step

1. Define scope – Business units, systems, or entire organisation
2. Conduct risk assessment – Identify risks, threats, and treatment plans
3. Document ISMS policies and procedures
4. Implement Annex A controls – Covering organisational, technical, and physical security
5. Run an internal audit – Detect and remediate gaps
6. Engage certification company for Stage 1
7. Stage 2 audit execution – Live testing, staff interviews, evidence review
8. Certification decision – Accreditation awarded for three years, with surveillance audits annually

Common ISO 27001 Audit Findings

Based on Australian market experience, frequent non-conformities include:

• Incomplete risk registers or risk treatment plans
• Outdated or missing information security policies
• Lack of evidence for control operation (e.g., patching, access reviews)
• Inconsistent internal audit records
• Weak third-party supplier risk management

These issues can delay certification or lead to conditional outcomes.
