The Australian Transport Safety Bureau (ATSB) is now investigating six separate incidents at Sydney Airport in just over a month, after two further close calls involving taxiing aircraft were reported. The new cases, on 16 and 25 August, involved Virgin Australia, Qantas, QantasLink and Jetstar planes, and add to growing concern about air traffic control operations at Australia's busiest airport, which has already been linked to staff shortages and training delays.

The 16 August incident saw a Virgin Australia plane fail to acknowledge an instruction to give way to a Qantas aircraft while taxiing, though the Qantas crew spotted the approaching plane and braked in time to avoid contact. The second, on 25 August, involved air traffic controllers giving a Jetstar crew incomplete pushback information, causing confusion over sequencing. Both were classified as safety incidents rather than serious ones, as there was no immediate collision risk. They join four other cases being probed since late July, including a serious 9 August near-collision between a Jetstar and a Qatar Airways plane that injured a Jetstar crew member and damaged the Qatar aircraft; ATSB expects its investigations to conclude within eight weeks.
