Each Five Eyes partner collects information over a specific area of the globe in accordance with their national priorities, but their collection and analysis activities are orchestrated to the point that they essentially act as one. Precise assignments are not publicly known, but research indicates that Australia monitors South and East Asia emissions. New Zealand covers the South Pacific and Southeast Asia. The UK devotes attention to Europe and Western Russia, while the US monitors the Caribbean, China, Russia, the Middle East and Africa.

As it did during the Cold War, Canada’s arctic territory provides considerable sigint advantage. Canadian Forces Station Alert, on the northern tip of Ellesmere Island, Nunavut, was originally an arctic weather station, but began sigint duty by eavesdropping on northern regions of the Soviet Union in 1958. Alert remains active today, collecting information from the interior of Russia and China.20 Other Canadian sigint assets reach into Latin America and out into the North Atlantic and North Pacific Oceans.
