Flight cancellations and delays occurred at Sydney Airport on the morning of September 11, 2026, with Air Traffic Flow Management (ATFM) measures enacted due to roster constraints linked to a shortage of air traffic controllers. These ATFM measures were lifted at 8:15 a.m. local time (2215 GMT on September 10, 2026), though delays of no more than 10 minutes were expected for the rest of the morning.
Airservices Australia, responsible for Australia’s air traffic, cited roster constraints and the need to safely manage aviation demand as reasons for enforcing ATFM measures. The shortage of air traffic controllers at Sydney Airport
caused the disruptions, and the federal agency described the staffing challenges as necessitating these steps.
Impact on Qantas Flights and Airlines
Qantas flights faced significant disruptions, with delays exceeding one hour on some services. In addition, six flights were cancelled on the morning of September 11, requiring travelers to adjust plans. After lifting the ATFM measures, additional delays were expected to be limited to 10 minutes for the remainder of the morning.
Airservices Australia Response and Official Actions
An Airservices Australia spokesperson stated, “Airservices acknowledges the ATFM measures may have caused some disruptions to airline scheduling, and is working with airlines to reduce delays and the impact on passenger travel as much
as possible.” The agency is actively recruiting more air traffic controllers and is developing procedures to call on additional staff as needed to manage demand safely.
Background of Near-Misses and Federal Scrutiny
The disruptions come amid continuing investigations by the Australian Transport Safety Bureau into six near-misses at Sydney Airport within about a month. These close calls have prompted scrutiny of air traffic control staffing amid global shortages and concerns over controller fatigue highlighted in recent reports.
Airservices Australia CEO Rob Sharp and other senior executives were scheduled to appear before a Senate committee on September 11, 2026, to address these safety concerns and the state
of Australia’s aviation sector.
Future Actions and Recruitment Efforts
In response to the situation, Airservices Australia is recruiting additional air traffic controllers and seeking ways to mobilize extra staff when needed. These efforts aim to address air traffic controller shortages and improve roster management to ensure safer operations at Sydney Airport.
