Penetration testing is becoming a core requirement for cybersecurity compliance across various sectors in Australia. With increasing cyber threats and stricter data privacy laws, businesses—especially those in finance, healthcare, education, and government—must conduct regular security testing, including penetration testing (pentesting), to stay compliant and secure.

This blog covers the penetration testing requirements, regulatory standards, mandatory vs. recommended guidelines, and best practices for organizations operating in Australia.

What Is Penetration Testing?

Penetration testing is a simulated cyber-attack on a system, application, or network to identify and exploit vulnerabilities. The goal is to find weaknesses before malicious actors can. It’s an essential part of proactive cybersecurity and plays a critical role in meeting compliance obligations in Australia.

Why Is Penetration Testing Critical for Australian Compliance?

Australia has strengthened its cyber regulations, especially after high-profile data breaches in 2022–2024. Now, organizations must prove they are taking steps to protect user data and infrastructure. Regular penetration testing is a key part of this demonstration.

Key Benefits:

• Identifies security vulnerabilities before attackers do

• Supports compliance with laws like the Privacy Act and APRA CPS 234

• Builds trust with stakeholders, partners, and clients

• Helps avoid penalties and public exposure after a data breach

  
  

Australian Regulatory Requirements for Penetration Testing

1. Australian Privacy Act 1988 (amended)

The Privacy Act, especially after amendments in 2022, requires organizations to implement "reasonable steps" to secure personal information. Penetration testing is considered a best practice to fulfill these obligations.

Who it applies to: Businesses with a turnover of over $3 million, health providers, and any entity handling sensitive personal data.

2. APRA CPS 234 – Information Security Standard

Mandatory for APRA-regulated entities like banks, insurance companies, and superannuation funds.

Key requirement:

• Entities must test the effectiveness of information security controls regularly.

• Penetration testing should be risk-based and performed at least annually.

3. Essential Eight (from the ACSC)

The Australian Cyber Security Centre’s Essential Eight is a maturity model for improving cyber resilience.

While not legally binding for all, penetration testing is recommended under:

• Maturity Level 2+

• Mitigation strategies for "security patching" and "application control"

4. ISO/IEC 27001 Certification

Many Australian organizations aim for ISO 27001 compliance. Regular penetration testing is a critical part of maintaining the certification, under Clause A.12.6.1 (Technical Vulnerability Management).

5. Australian Government ISM (Information Security Manual)

Agencies under the Australian Government must comply with the ISM. It mandates periodic vulnerability assessments and penetration testing of ICT systems.

What Should Be Included in a Penetration Test?

For compliance, a penetration test should include:

Penetration Testing Frequency Guidelines

Industries in Australia That Require Penetration Testing

• Financial Services (APRA-regulated)

• Health and Aged Care (My Health Record System)

• Education (handling student personal data)

• Retail and eCommerce (PCI-DSS compliance)

• Critical Infrastructure (under SOCI Act)

• Government and Public Services

Choosing a Penetration Testing Provider in Australia

When selecting a provider:

• Ensure they follow industry-standard frameworks (e.g., OWASP, NIST, PTES)

• Require NDA and data handling agreements

• Choose providers with local data centers if required by compliance

• Validate their experience in compliance-specific testing

• Ensure detailed, actionable compliance-ready reporting

Common Tools Used in Penetration Testing

Challenges in Meeting Compliance with Pentesting

• Budget constraints for small organizations

• Shortage of skilled cybersecurity professionals

• Misaligned scope with compliance requirements

• Lack of awareness about compliance obligations

Best Practices for Compliance-Driven Pentesting

✅ Align pentest scope with regulatory standards
✅ Use certified ethical hackers (CEH, OSCP)
✅ Conduct testing at least once a year
✅ Combine automated scanning with manual testing
✅ Include social engineering if required by compliance
✅ Document everything for audits and regulators

Future of Compliance & Penetration Testing in Australia

• Mandatory breach reporting is driving demand for security testing

• Cloud-based pentesting platforms will become more common

• AI-powered threat detection will be used to augment pentesting

• Penetration testing will integrate into DevSecOps and CI/CD pipelines

• Continuous security testing may become a regulatory norm

Conclusion

In Australia’s tightening cybersecurity landscape, penetration testing is no longer optional. It's a critical requirement for regulatory compliance, risk mitigation, and customer trust. Whether you're in finance, healthcare, education, or retail, implementing regular penetration testing aligned with standards like APRA CPS 234, Privacy Act, and ISO 27001 is essential in 2025 and beyond.

FAQs

What is penetration testing in Australia?

Penetration testing in Australia is a simulated cyber-attack to identify vulnerabilities in systems, often required for compliance with cybersecurity regulations.

Why is penetration testing important for compliance?

Is penetration testing mandatory under APRA CPS 234?

Yes, APRA CPS 234 mandates regular security testing, including penetration tests, for all regulated financial entities.

How often should Australian companies perform penetration testing?

At least annually or after significant system changes, depending on regulatory and organizational risk.

What laws in Australia require penetration testing?

Key regulations include the Privacy Act 1988, APRA CPS 234, ISO/IEC 27001, and the ACSC Essential Eight framework.

What is APRA CPS 234?

It is a standard that outlines minimum information security requirements for APRA-regulated entities, including penetration testing.

What is the Privacy Act 1988's requirement on security?

It requires organizations to take "reasonable steps" to protect personal information, often including regular security testing.

What is the ACSC Essential Eight?

A cybersecurity maturity model from the Australian Cyber Security Centre, recommending penetration testing at Maturity Level 2 and above.
