Critical infrastructure resilience

​​Critical infrastructure provides services that are essential for everyday life such as energy, food, water, transport, communications, health and banking and finance.

Secure and resilient infrastructure supports productivity, and helps to drive the business activity that underpins economic growth.

A disruption to critical infrastructure could have serious implications for business, governments and the community, impacting supply security and service continuity.

The Critical Infrastructure Resilience Strategy, which comprises a policy statement and a plan for practical implementation, aims to ensure the continued operation of critical infrastructure in the face of all hazards.

The Department of Home Affairs is the lead Australian Government agency for critical infrastructure. We are responsible for the Critical Infrastructure Centre and managing the Trusted Information Sharing Network (TISN), an environment where business and government can share information on critical infrastructure vulnerabilities and techniques to assess and mitigate risk.

While the Critical Infrastructure Centre and the Security of Critical Infrastructure Act 2018 focuses specifically on foreign involvement, the Government remains committed to an all-hazards approach to protecting critical infrastructure as specified in the national Critical Infrastructure Resilience Strategy, and the work of the Trusted Information Sharing Network (TISN).
