​​​​​​​​​​​​​​​​​​​​​​​​​​​​Trusted Information Sharing Network​

The Trusted Information Sharing Network (TISN) is the Australian Government’s primary engagement mechanism with industry on critical infrastructure. The TISN was established with the assistance of critical infrastructure owners and operators in 2003. It brings together stakeholders from across the critical infrastructure community, including critical infrastructure owners and operators, supply chain entities, peak bodies, academics, research institutes, and all levels of government.

Through the TISN, member organisations meet regularly within and across sector groups in a secure, non-competitive environment to enhance the security and resilience of critical infrastructure by:

  • understanding threat, vulnerability and consequence to better manage risk
  • increasing awareness and understanding of cross-sector dependencies and the impacts of a disruption to any critical infrastructure sector
  • enhancing communication channels and networks between industry and all levels of government
  • identifying gaps and implementing appropriate mitigation strategies within each sector
  • informing future policies and programs to support critical infrastructure resilience.

The work of the TISN is guided by the Critical Infrastructure Resilience Strategy. The government is enhancing the TISN to:

  • help the critical infrastructure community meet the requirements of regulatory reforms under the Security of Critical Infrastructure Act 2018
  • improve industry education, collaboration and information sharing under non-regulatory reforms guided by an updated Strategy.

The TISN is currently made up of:

These groups are overseen by the Critical Infrastructure Advisory Council (CIAC).

The CISC is in the process of expanding the TISN to increase the number of critical infrastructure sectors, in line with the broadening of sectors under the legislative reforms, and introduce sector segmentation.

Membership will increase to welcome functional representatives from organisations, additional industry groups and peak bodies, academics, research institutes, as well as all relevant levels of government.
