Anna, your excellent report is in the format of being a 'quote' rather than the usual font.
I wasn't there and you were, but if the noisy chap had totally calmed down, why should he be kicked off the flight (assuming he wasn't drunk, swearing or aggressive.) Is this a case of QF staff being overly politically correct? The chap may have had legitimate reasons for wanting the flight to be punctual. While we are not the USA, if this was a flight in the USA there's a chance that far more than one passenger would be loudly complaining. In mainland China, it might be even more magnified!
Great information that there were 53 connecting from QF94 to the ADL-bound flight. This is one reason why despite many of us such as the redoubtable AFF member drron liking day flights to and ex (say) northeast or southeast Asia, sometimes they do not carry as many connecting passengers as the overnight flights (due to 'missing' same day connecting flights at one end, or even both) and so if airlines ranked flights in terms of seat occupancy, the day flights might not come up trumps.
Anna's aircraft, B738 VH-VZO subsequently yesterday operated QF1294 from ADL up to BNE and QF633 from BNE down to MEL, the latter arriving at 2217, 87 minutes late after Anna had arrived in ADL earlier in the day at 1532 which was 192 minutes late.
While probably unconnected, it is about 48 minutes late this morning (Saturday 2) on QF702 from MEL up to CNS.
