Sydney Airport experienced four near-miss incidents between July and August where aircraft came dangerously close to colliding on runways, prompting federal investigations into air traffic control operations. Despite these serious safety concerns, Transport Minister Catherine King stated the airport remains safe for travellers, whilst the country's transport watchdog identified staff resourcing as a recurring area of concern. The incidents highlight growing strain on air traffic control systems both nationally and globally.

Air traffic controllers at Sydney Airport took an average of 17 days of sick leave last financial year—higher than at other major Australian airports—contributing to staffing shortages, as controllers are legally required to take leave if unwell or fatigued. In one incident, two planes stopped with just 30 metres between them; in another, aircraft came within 120 metres of each other after an air traffic controller's seven-second break. Sydney Airport recorded a 20 per cent higher incident rate than other major Australian airports, prompting the establishment of an independent assurance panel chaired by retired Air Vice Marshal Ken Robinson to oversee safety improvements.
