It's after 12 noon on 1 April 2019 so these contributions are genuine.
QF23 with its northern summer schedule of a 1050 hours SYD departure was off blocks 29 late. Arrival in BKK should be at 1715, 35 late.
The long MEL - LAX QF93 (A388 VH-OQD) is the 1000 hours that departed 82 minutes behind time, so arrival is estimated at 0726, 61 late (same day). This may delay the 0820 hours Monday QF11 from LAX across to JFK, and in turn the returning transcontinental USA flight QF12, plus possibly then at least the SYD and BNE-bound Monday evening departures from LAX.
Although the Sunday afternoon 31 March ex SYD QF1 was only expected to be half an hour tardy in pushing back in SIN, it did so at 0130 hours (95 late) so LHR expected arrival has become 0815 hours, 110 late.
