A Jetstar flight departing Sydney Airport for the Gold Coast almost collided with a Qatar Airways plane at 7am on Sunday. A Jetstar spokesperson said its aircraft was following instructions from air traffic controllers when the pilots were forced to brake firmly as another aircraft came into "close proximity". The bureau's commissioner Angus Mitchell said flight crew, tug operators, air traffic controllers and other witnesses would be interviewed and relevant footage would be reviewed. Air traffic control was reportedly operating under restricted hours between 6am and 8am on Sunday, reducing the number of flights arriving and departing due to staffing shortages. Safety failures such as those seen on Sunday were indicative of an aviation workforce in crisis, a union representing air traffic controllers said.
