Six flights were cancelled and numerous others delayed, including some Qantas flights by more than one hour, at Sydney Airport on the morning of September 11, 2026. The disruptions affected passenger travel in and out of Australia’s busiest airport during peak hours.
Airservices Australia implemented Air Traffic Flow Management (ATFM) measures to manage aviation demand safely amid staffing roster constraints. These measures were lifted at 8:15 a.m. local time, though minor delays of up to 10 minutes were anticipated for the remainder of the morning. An Airservices spokesperson acknowledged these controls disrupted airline schedules and said the agency is collaborating
with airlines to mitigate delays.
The root cause of the delays was a shortage of available air traffic controllers caused by roster limitations. Airservices Australia is actively recruiting additional controllers and improving the process for calling in extra staff during busy periods to address this shortage. A shift manager described the staffing situation as “a bit insane,” reflecting the strain on personnel.
Recent Safety Concerns and Senate Inquiry
These operational challenges come amid heightened scrutiny following six near-miss incidents at Sydney Airport in roughly one month. Internal records revealed controller fatigue concerns during a July near-miss involving two Qantas aircraft. The Australian Transport Safety Bureau is
investigating these events for common safety issues or contributing factors. Airservices Australia’s CEO Rob Sharp and senior executives are scheduled to appear before a Senate committee reviewing the aviation sector’s ability to provide reliable and affordable services to regional Australia.
