Case Study - Innovative Solutions

Australian Prime Minister John Howard announced in 2001 that Australia would have armed air marshals flying on Australian carriers in an anti-hijacking role and that they would be operational three months later.


At this time, Australia had no such capability and 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 and operational delivery of the program. We had less than six weeks to have the capability deployed. We resolved a number of challenges and the first officers deployed on selected domestic flights within six weeks.

Case Study - Innovative Solutions

Citadel established multiple concurrent work teams and empowered them to develop innovative solutions for subsequent consideration and approval.


Following a very busy six weeks, on 24 December 2001, we 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”.
