Our Client Networks

K39 Consulting principally operates via Capability, Acquisition and Sustainment Group (CASG) Major Service Providers model for the delivery of ‘above the line’ support services. The implementation of this innovative approach to the Defence market has provided the Commonwealth Defence sector the opportunity to adopt a more strategic and integrated approach to its support services requirements.

K39 Consulting provides acquisition and sustainment services directly to CASG’s System Project Offices across multiple Domains via the Nova, KEY (KBR & EY) and Downer Major Service Provider network. In addition, K39 Consulting provides services to Defence Support Services Panel members and Defence Industry.

K39 Consulting works with Nova in providing services intrinsic to the delivery of their Strategic Partner, Capability Partner and Integrated Work Partner services.
