Incident Response Planning for Australian Organisations
Intrix develops incident response plans for Australian organisations, covering regulatory obligations under APRA CPS 234, the SOCI Act, and the NDB scheme. Plans include response playbooks, regulatory reporting workflows, business continuity integration, and tabletop exercise testing.
A Plan is Your Best Defence in a Crisis
Cyber incidents are inevitable. In Australia, the average breach costs over $3.35 million, mostly due to slow detection and poor response. Without a tested incident response plan, organisations lose time, make errors, and risk non-compliance.
Regulators expect strong, tested incident response plans. APRA CPS 234 requires annual IR testing for financial institutions, the SOCI Act enforces strict reporting timelines, and the Privacy Act’s NDB scheme mandates rapid breach notification. Leadership is now personally accountable for cyber resilience.
An effective IR plan turns chaos into control. It defines roles, communication, and decision-making so your team can act fast under pressure. But a plan only works if it’s practical, tested, and integrated with your wider business continuity strategy.

Incident Response Planning FAQ
Intrix develops incident response plans for Australian organisations covering regulatory obligations under APRA CPS 234, the SOCI Act, and the NDB scheme. Plans include response playbooks, regulatory reporting workflows, business continuity integration, and tabletop exercise testing. Contact Intrix on 1300 931 727 to get started.
What should an incident response plan include?
An effective incident response plan should include a defined incident response team structure with clear roles and contacts, step-by-step response playbooks for common incident types such as ransomware, business email compromise, and insider threats, incident classification and severity levels, regulatory reporting workflows with required timeframes, internal and external communication protocols, and recovery and lessons learned procedures. Intrix develops all of these components tailored to each organisation’s regulatory environment and business structure.
How often should an incident response plan be tested?
Incident response plans should be tested at least annually through tabletop exercises or simulated incident scenarios. APRA CPS 234 requires annual IR testing for regulated financial institutions. The ACSC and ISO 27001 also recommend regular testing as part of a mature security posture. Intrix conducts tabletop exercises and cyber wargames to test plan effectiveness and identify gaps before a real incident occurs.
What are the regulatory requirements for incident response in Australia?
Australian organisations face multiple incident response obligations depending on their sector. APRA CPS 234 requires financial institutions to report material cybersecurity incidents to APRA within 72 hours and to test IR plans annually. The SOCI Act requires critical infrastructure operators to report significant incidents to the ACSC within 12 hours and relevant impact incidents within 72 hours. The Privacy Act’s NDB scheme requires organisations to notify the OAIC and affected individuals of eligible data breaches as soon as practicable, and within 30 days of becoming aware. Intrix builds regulatory reporting playbooks for all of these obligations into every IR plan.
How long does it take to develop an incident response plan?
Developing a comprehensive incident response plan typically takes four to eight weeks from initial discovery and requirements analysis to final sign-off and training. The timeline depends on the size of the organisation, the number of regulatory frameworks that need to be addressed, and the availability of key stakeholders for review and approval. Intrix follows a structured four-phase process covering discovery, plan design, stakeholder review, and tabletop testing.
