Just three months after police foiled a plan for a bomb attack on an Emirates flight from Sydney, the police have yet again tightened security at the airport after foiling another attack last week. This time, police say, Australia will also introduce random searches of workers entering and inside its airports.

Earlier this month, the Council of Australian Governments signed off on a facial biometric agreement to give state and federal police real-time access to passport, visa, citizenship and driver’s license images for criminal investigations including those involving suspected terrorists.
