A data breach can cost your business thousands, damage trust, and trigger mandatory notifications under the Privacy Act, yet many organisations still lack a solid response plan. This video explains what legally counts as a data breach, when you must notify affected individuals and the OAIC, and why organisations over 3 million in annual turnover or health service providers need a documented response plan. You will learn how to structure your breach response playbook, including response team roles, escalation processes, templates for internal reports and notifications, communication strategies, and post-incident review steps. We also cover early detection, containment, assessment of “serious harm”, and the importance of regular training and testing so your business is prepared before a breach occurs.
