On September 11, 2026, Sydney Airport faced flight cancellations and delays due to a shortage of air traffic controllers. Airservices Australia enacted Air Traffic Flow Management (ATFM) measures “due to roster constraints and to safely manage aviation demand,” which were lifted at 8:15 am AEST (2215 GMT on September 10, 2026), though delays of no more than 10 minutes persisted for the rest of the morning.
Flight Delays and Cancellations Impact Operations
Qantas flights were notably affected, with some experiencing delays exceeding one hour and six flights cancelled. Sydney Airport’s website did not specify reasons for the disruptions, referring inquiries to Airservices Australia. The ATFM measures
caused disruptions to airline scheduling and passenger travel, according to official statements.
Airservices Australia’s Official Response and Staffing Measures
Airservices Australia acknowledged the scheduling disruptions and stated it is cooperating with airlines to reduce delays and impact on passengers. The agency is recruiting more air traffic controllers and making staff availability easier on short notice. Airservices Australia CEO Rob Sharp and other senior executives were scheduled to appear before a Senate committee on September 11, 2026, to discuss challenges facing Australia’s aviation sector and its capacity to provide reliable services.
Background of Safety Concerns and Investigations
The disruptions followed approximately six near-misses reported at Sydney Airport within about a month, involving controllers flagged
as having a high fatigue risk. One air traffic control shift manager described the staffing situation as “a bit insane.” The Australian Transport Safety Bureau is investigating these incidents to identify common safety issues amid ongoing scrutiny and a global shortage of air traffic controllers.
