Chinese naval codes
Peter Cronau raises the key question: Why wouldn’t Defence have been monitoring transmissions from the ships from when they were first off Queensland?
Of course, the warning to aircraft would have been in plain language.
But if you think of the cracking of the German Enigma code and of the Nazi high command code during WWII, how good is Defence at reading encrypted codes from other navies? After all, right now Russia, Iran and China are conducting joint naval exercises in the northwest Indian Ocean (yes, that’s the one that touches Australia for thousands of kilometres), according to Al Jazeera.
This is a place where an Australian naval officer currently commands a joint naval task force, although at the moment it is reportedly a force without an Australian ship. And last year a three-ship Iranian naval group reportedly circumnavigated the globe.
