According to the CX on line timetable the only A330 service to Australia after end October 2020 will be CX 161/2 to/from SYD. ADL, BNE and PER will be all A350s and MEL a mix of A350 and 77W. This also fits with the reports that 8 of the existing 10 A33Ks will be converted to A33Js. Longer term additional A350s could be added to replace older A330s which could then be moved to the Dragon to replace the then most ancient, like the 27 year olds (B-HLJ & K), they they are still using.
