# Aviation safety investigation at Sydney Airport > Live situation record from CLSTR: https://clstr.news/situations/aviation-safety-incidents-at-sydney-airport > Updated: 2026-09-11T01:46:40.000Z. Sources: 29. Developments: 6. The Australian Transport Safety Bureau (ATSB) is investigating a series of six safety incidents at Sydney Airport involving runway incursions and loss of separation among airlines such as Qantas, Jetstar, and Virgin Australia. New details regarding the July 27 near-miss—where a Qantas Boeing 737 was authorized to cross an active runway while a Qantas Link Dash 8 was landing—indicate significant staffing and fatigue concerns. Internal records and call recordings show that of the ten air traffic controllers on duty during that incident, five were flagged as being at ‘high fatigue risk’. Of the three controllers directly involved in the near-miss, two were rated at high fatigue and one at medium fatigue. During an internal call, a shift manager described the staffing situation as ‘a bit insane.’ Other incidents under investigation include an August 9 emergency braking event involving a Jetstar aircraft and a Qatar Airways Boeing 777, which resulted in a crew member sustaining injuries, and an August 16 event where a Virgin Australia Boeing 737 braked to avoid a Qantas 737. An August 25 incident involved a Jetstar Airbus A320 crew halting a pushback due to incomplete taxi information regarding a nearby Bombardier Dash 8. Staffing shortages have since caused operational disruptions. On a recent Friday morning, Airservices Australia implemented Air Traffic Flow Management (ATFM) measures due to roster constraints, resulting in six flight cancellations and delays for several Qantas flights. Airservices Australia stated it is working to recruit more controllers, and executives are scheduled to appear before a Senate committee to discuss the state of the aviation sector. The ATSB continues to review flight recordings and interview personnel to identify common contributing factors. Airservices Australia has declined to comment due to the ongoing investigation. ## Claims - The ATSB has launched formal investigations into four high-risk operational events occurring at Sydney Airport within a four-week period. (corroborated by 4 sources) - On July 27, a QantasLink Dash 8 and a Qantas Boeing 737 nearly collided when the 737 was cleared to cross a runway while the other was landing. (corroborated by 3 sources) - On August 9, a Jetstar Airbus A320 and a towed Qatar Airways Boeing 777 encountered a conflict on a taxiway, resulting in an abrupt stop. (corroborated by 2 sources) - On August 16, a Virgin Australia Boeing 737 and a Qantas 737 were involved in a taxiway incident after a failure to correctly read back instructions. (corroborated by 2 sources) - On August 25, a Jetstar Airbus A320 was directed toward a taxiing Bombardier Dash 8 due to incomplete traffic information. (corroborated by 2 sources) - One cabin crew member sustained a serious injury during an abrupt stop on August 9. (corroborated by 2 sources) - Qantas stated that their aircraft and crews were following instructions provided by Air Traffic Control during the incidents. (corroborated by 2 sources) - The frequency of these incidents has raised questions regarding air traffic controller shortages in Australia.
