On 22/12 there was a breakdown in separation between a Cathay Pacific A330 (B-HLV) (HKG-MEL) and a Virgin Blue B737 (VH-VUJ) (MEL-DRW) at FL370 somewhere over NT.
from the ATSB
An Airbus Industrie A330 was southbound at FL370 and a Boeing Company 737 was northbound on the reciprocal track also at non-standard FL370. When the crew of the A330 questioned the controller, the controller instructed the A330 crew to climb to FL380 and cleared the aircraft to divert right of track. The crew of the 737 then advised the controller they were diverting 10 NM right of track. There was a breakdown of separation standards. The investigation is continuing.
Merry Christmas
