Chief Information Officer Group

What we do

The Chief Information Officer Group (CIOG) within the Department of Defence leads the integrated design, cost effective delivery and sustained operation of Defence’s Single Information Environment (SIE) to support military and business operations.

In simple terms, the SIE encompasses the information, computing and communications infrastructure of the Department of Defence along with the management systems and people that deliver that infrastructure. It includes Defence’s information assets, computing networks, business applications and data. It includes the communication standards and spectrum required for Battlespace networks. The infrastructure CIOG provides is essential and integral to core Defence functions including intelligence, surveillance, reconnaissance, communications, information warfare, command and management.

It is the responsibility of CIOG to ensure that the Department of Defence has a dependable, secure and integrated information environment, capable of supporting its operational and management needs.
