Salient point, Ansett, but probably the airlines (and passengers) have to pay themselves.
That said, if one missed an international connection and had been booked to connect from a domestic flight on the one PNR, most international legacy (not LCC) airlines would put a traveller up in an hotel if it came to that, although rebooking might be fastest and preferable.
Also on Monday 25 September, QF501 (0600 hours BNE - SYD) took off at 0801 so it looks to have been held by ATC in BNE for a significant period of at least 90 minutes prior to being able to push back. B738 VH-VYD should arrive at 0947, 132 minutes tardy but as at 0910, this aircraft had only just left its holding pattern to Singleton's west.
QF2019 (0630 hours ARM down to SYD that took off at 0824) is similarly affected with Q300 VH-SBG suggested as arriving at around 0945, 115 minutes late.
The WTB - SYD QF2015 (Q400 VH-QOV) took off at 0758 despite its 0605 hours scheduled departure. Arrival looks to be at about 0952, 127 minutes past the allotted.
