Cyber Incident Response Plan Template for Australian Businesses
Last updated: July 2026 · Prepared and reviewed by the Vintaris security team
Most incident response plan templates are American boilerplate: NIST phases, US legal references, and nothing about the obligations that actually bind an Australian business. This one is built for Australia: the Notifiable Data Breaches clock, insurer notification as an early step, and ACSC reporting, in plain English, in Word format, free.
The six phases every plan needs
Prepare
Roles, contacts, backups tested.
Detect
How you find out.
Contain
Stop the spread.
Eradicate
Remove the attacker.
Recover
Restore and verify.
Review
What changes so it never repeats.
The structure aligns with the phases NIST and the ACSC describe; the content below is where the Australian specifics live.
What the template contains
Roles and contacts.
Incident lead, deputy, decision-makers, and the external numbers that matter: your insurer’s hotline first, then IT provider, legal, and the ACSC.
Insurer notification, early.
Most cyber policies require notification before you act and the use of approved responders. Acting first and calling later is how covered incidents become refused claims.
Detection and escalation.
What counts as an incident, who staff tell, and the rule that reporting a suspicion is never punished.
Containment decisions.
Isolate or keep trading, disconnect or observe, with the questions to answer before the pressure hits.
The NDB assessment.
Australia’s Notifiable Data Breaches scheme runs a 30-day assessment clock from suspicion, not confirmation. The template includes the assessment worksheet and the OAIC notification path.
Communications.
Holding lines for staff, customers and media, written calmly in advance.
Recovery and verification.
Restore order, credential resets, and how you confirm the attacker is actually gone.
Post-incident review.
The one-page debrief that turns a bad week into a stronger plan.
The first 24 hours
Isolate affected systems and reset exposed credentials.
Most policies require notification before further action; many fund the response.
Logs and images kept before anything is wiped or rebuilt.
The 30-day assessment runs from suspicion, not confirmation. Start it consciously.
Staff and customer holding lines out; ACSC report lodged.
Where should we send it?
What to do after a cyber attack
Contain first: isolate affected systems and reset credentials. Notify your insurer before taking further action, most policies require it and many fund the response. Preserve evidence rather than wiping and rebuilding immediately. Start the NDB assessment clock consciously, and report to the ACSC. Then work the plan, which is precisely why the plan must exist before the attack does.
A template is the floor, not the finish
A downloaded plan nobody has tested is a hope, not a control. The upgrade path: tailor it to your business, then pressure-test it with a tabletop exercise, and verify the controls it assumes (tested backups, MFA, EDR) actually exist, which is what our cyber security assessment does. Insurers increasingly ask for exactly this evidence.
Frequently asked questions
What should an incident response plan template include?
Roles and contacts, insurer notification steps, detection and escalation rules, containment decisions, the Notifiable Data Breaches assessment process, communications holding lines, recovery verification, and a post-incident review. For Australian businesses, the NDB clock and insurer conditions are the sections generic templates miss.
Is this template aligned to NIST?
The phase structure aligns with the NIST incident response lifecycle and ACSC guidance, but the content is written for Australian obligations rather than US ones. If a customer or tender specifically requires NIST-format documentation, the mapping is straightforward and we can help.
Is the template really free?
Yes. Enter your email and the Word document is sent immediately. No calls unless you ask for one.
What is a data breach incident response plan?
The same plan with the data-handling sections doing the heavy lifting: what was exposed, how many records, the NDB assessment, OAIC notification, and affected-individual communications. Section 5 of the template covers it.
