Australia is investigating a fourth close call involving Qantas aircraft at Sydney Airport in less than a month, according to reports from multiple outlets. In the incident, a Qantas Airbus A321 preparing to depart for the Gold Coast brakes to avoid another Qantas aircraft, a Boeing 737, that is arriving from Melbourne.

Channel NewsAsia reports the event involves the A321 departing preparation on Tuesday, Aug 18, when the 737 is arriving from Melbourne. Free Malaysia Today describes the same situation as another near-miss that occurs within a short period. Both accounts focus on the safety risk posed by close aircraft movements and the response by the departing aircraft’s braking.

Across the sources, the shared details are the aircraft types and routes (Sydney–Gold Coast for the A321 and Sydney–Melbourne for the 737) and that investigators treat the event as part of a pattern of recent close calls at the airport. The outlets do not provide additional findings, such as regulator conclusions or official causes, in the excerpts provided.
