"The five-year contract with Thales begins this month and is valued at $51 million.
"The services will be delivered from facilities located in Canberra and Perth," Greg Combet, Minister for Defence Personnel, Materiel and Science, said.
"This win consolidates our reputation for consistent, high-quality performance in support of national security requirements," Chris Jenkins, Thales Australia's managing director, said.
"Cost-effectiveness, innovation and demonstrated responsiveness to urgent operational requirements were also important measures over the life of the previous contract."
The CISSO Support Program is comprehensive, in that it encompasses a suite of products and services from building and sustaining Deployable Local Area Networks (DLANs) to enhancing specialist software and managing and operating the CISSO Support Test and Integration Facility.
Over the course of the existing CISSO contract, Thales has delivered 140 DLANs ranging in size from ultra-light, single-laptop systems to heavy systems designed to support deployed headquarters comprising over 150 users.
These systems are used extensively by the ADF in operations around the world.
