Disturbing details:
High-grade military explosives used to build the bomb were sent by air cargo from Turkey as part of a plot "inspired and directed" by the militant Islamic State group, police Deputy Commissioner National Security Michael Phelan said. ...
"This is one of the most sophisticated plots that has ever been attempted on Australian soil," Phelan said. ...
Since police revealed details of the scheme, security experts said it exposed weaknesses in air cargo screening, particularly in Turkey, where intelligence agencies have been weakened by a government purge in the wake of last year's failed coup.
"Islamic State is now positioned in Turkey such that it can send military-grade explosive via cargo flights out of Turkey around the world," said Deakin University's Barton. "Now presumably Sydney is not a one-off and they are going to try this elsewhere and that's a level of risk that we hadn't thought of before."
