An air traffic controller has been stood down after two commercial jets narrowly avoided a collision on the tarmac at Sydney Airport, triggering a major federal safety investigation.

The incident, which occurred around 7:00 am, involved a Gold Coast-bound Jetstar Airbus A320 and a Qatar Airways Boeing 777. The Jetstar flight, JQ402, was taxiing toward the runway when its pilots were forced to perform an emergency brake maneuver to avoid hitting the larger Boeing aircraft.

Injuries and Immediate Fallout

While no passengers were hurt in the sudden halt, one Jetstar cabin crew member sustained minor injuries and was assessed by paramedics at the scene. Airservices Australia confirmed that the air traffic controller involved has been suspended from duty, in line with standard safety protocols, pending a comprehensive internal review.

The Australian Transport Safety Bureau (ATSB) has launched an investigation, revealing that the incident resulted in physical damage to the connection between the Qatar Airways 777’s nose gear and its aircraft tug.

Staffing Constraints and Growing Delays

The close call comes amid growing pressure on Sydney Airport’s operations. The facility was operating under strict flow restrictions between 6:00 am and 8:00 am on Monday, capping the number of arrivals and departures. Airservices Australia has since implemented "departure spacing" measures to safely manage the airborne queue, warning passengers to expect ongoing delays as they coordinate with airlines to minimize disruptions.

The incident follows a weekend of intense travel chaos where chronic staffing shortages and rostering issues led to delays and cancellations affecting more than 150 flights.

A Concerning Trend

ATSB Chief Commissioner Angus Mitchell stated that investigators are currently gathering flight data, interviewing the flight crews, tug operators, and air traffic controllers, and reviewing CCTV footage to understand the breakdown in communication.

"At this stage, we don't know what all the instructions were," Mitchell said. "We will retrieve that information from recorded devices and interviews to establish exactly what went wrong and ensure a similar incident is prevented."

This is the second runway safety breach at Sydney Airport in less than a week. Last week, the ATSB opened an investigation into a "breakdown of coordination" that saw a Qantas Boeing 737 from Queenstown cleared to cross a runway while a QantasLink flight from Canberra was still in its landing roll.

Government Demands Action

The escalating issues have drawn sharp criticism from New South Wales Premier Chris Minns, who described the situation as deeply concerning for both passenger safety and the state's economy.

"Not just the safety risks, but we want to make sure that the airport is operating at full capacity," Premier Minns said. "We don't want to see people disrupted... because there's not enough air traffic controllers."

Minns urged authorities to resolve the critical workforce issues immediately, pointing out that a tight labor market makes recruitment difficult, but emphasizing that staffing these vital roles is "not a 'nice-to-have', it's a must-have" ahead of the opening of the new Western Sydney Airport.
