Defence & National Security

Citadel provides secure video conferencing services to a number of sensitive government agencies. This solution delivers mission critical capabilities through a fully ‘turnkey’ managed services arrangement. Our team has been providing this service to Government since 1997, and has excelled at ensuring high availability and security in such missional critical environments:

      • Design of a High-speed IP-based network, integrating fixed telecommunications with satellite and tactical networks across hundreds of sites and thousands of users
      • Provision of secure video conferencing managed services to fixed and mobile sites within Australia and via international bridging services to other allied sites for Defence, Defence industry and other Government agencies on a 24/7 basis
      • Deploying tactical systems that can then access to fixed network via a secure national bridge
      • Real-time monitoring of the production environment including Initial problem discovery and security assurance
      • Documenting and tracking all operational aspects of the customer environment
      • Troubleshooting and trouble resolution
      • Escalation of problems to other parties as required
      • Release management including managing, tracking, and performing global software upgrades, defining and storing system configuration information, performing system testing as required, and resolving any and all associated software issues
      • Collation of statistics for reporting on cost effectiveness, availability and usage
      • Stakeholder and vendor liaison.


As a result of the hijacking of four aircraft in the USA on 11 September 2001, then Australian Prime Minister (PM) John Howard announced on 2 October 2001 that Australia would have armed air marshals flying on Australian carriers in an anti-hijacking role and that they would be operational by 31 December 2001. At this time, Australia had no such capability and, therefore, there was no directly-relevant expertise in Australia to meet this directive.
Members of Citadel’s advisory team were contracted to establish the capability for Government. This included strategic issues (such as the high level planning considerations, legislation, inter-agency cooperation, and funding) and operational delivery of the program (initial recruitment, training, tactics, methods of operation, and liaison with the airlines). We had less than six weeks to have the capability deployed. Because we were establishing a completely green fields program, our team faced the following issues:

      • no offices or staff
      • no trainers with expertise in Air Security Officers (ASO – air marshals) operations
      • no trainees
      • no mock-up aircraft to train in
      • no agreement with the airlines, pilots or cabin crew
      • no legal agreement on powers
      • no concept of operations
      • no conditions of service for ASO
      • no equipment, weapons, handcuffs or rig to carry equipment under clothing
      • no agreement by Government Departments with regards to the myriad of approvals needed to have armed officers on aircraft flights
      • no agreement on what ports ASO were to fly in and out of
      • no agreement with airport corporations to allow ASO to bypass screening (scanners would have detected the firearms and compromised identities of ASO to security point staff)
      • no agreed funding.


Each of the above challenges needed to be resolved and the first officers deployed on selected domestic flights within six weeks, so we established multiple concurrent work teams and empowered them to develop innovative solutions for subsequent consideration and approval. Once approved by Government, we then presented the concepts to Qantas, Ansett and Virgin Blue management, and ‘tweaked’ where necessary to ensure all stakeholders were clear of the requirement and committed to the program’s success.

Following a very busy six weeks, on 24 December 2001, Citadel received final Government authorisation to proceed and ASOs flew for the first time on board Australian aircraft at 4.30pm.

In 2004, Qantas senior managers went before a Parliamentary Committee and stated on the record that “the Australian ASO program is without doubt the world’s best practice”.
