Flight cancellations and delays took place at Sydney Airport on the morning of September 11, 2026, as a shortage of air traffic controllers forced Airservices Australia to implement Air Traffic Flow Management (ATFM) measures.
These ATFM measures were activated to address roster constraints and to safely manage aviation demand at the airport. The restrictions were lifted at 8:15 a.m. local time (2215 GMT on September 10), with residual delays limited to no more than ten minutes expected throughout the remainder of the morning.
Qantas Faces Significant Flight Disruptions
Several Qantas flights were impacted during the disruption, with delays exceeding one hour reported. Additionally, six Qantas
flights were cancelled, affecting scheduled travel plans for passengers on those services.
Cause and Investigation of Disruptions
The cause of the disturbances was identified as a shortage of air traffic controllers attributed to roster constraints. This staffing challenge comes amid ongoing investigations by the Australian Transport Safety Bureau into six near-miss incidents at Sydney Airport within approximately one month. A shift manager described the staffing situation during these events as “a bit insane.”
Some controllers involved in a July near-miss between two Qantas aircraft were noted as facing a high risk of fatigue, prompting greater scrutiny over air traffic control staffing at Sydney Airport amid
global shortages.
Airservices Australia Response and Industry Context
Airservices Australia acknowledged the ATFM measures may have caused disruptions to airline scheduling. A spokesperson stated the agency is collaborating with airlines to minimize delays and reduce the impact on passenger travel. Efforts are underway to recruit further air traffic controllers and improve staffing flexibility by enabling easier access to additional personnel when needed.
Airservices Australia CEO Rob Sharp and senior executives are set to appear before a Senate committee on September 11, 2026, which is examining Australia’s aviation sector reliability and affordability, partially in response to these recent staffing and safety issues.
