Wednesday : Seems it's Melbourne bound passengers from Los Angeles turn to suffer some delays.
After Sunday's QF94 (B789 ZND) was 103 minutes late departing LAX, and 79 minutes late on arrival into Melbourne, Tuesday's replacement QF96 (B789 VH-ZND) for the dropped Monday QF94, ran to time.
However Tuesdays' QF94 (B789 VH-ZNE) was 49 minutes late departing LAX, and is now due in Melbourne at 09:12 AEDT Thursday morning, 72 minutes late. This aircraft arrived on time on Monday with that day's QF93, so presume the delay occurred while it was at LAX maintenance. The aircraft was showing there on FlightRadar24 for about 12 hours before it moved to the departure gate.
