Just a point on RedTBar's "could have gone either way."
Once 20 hours Tour of Duty [TOD] is passed, it's the feeling of most pundits that neither the company [in this case QF] nor the PIC have a leg to stand on should there be a problem resulting in litigation.
Having dealt with this for over 40 years, they'd have been in BNE or elsewhere before breaking the 20hr limit and continuing to SYD.
Finally, yes, you can be that accurate once underway!!
G'day
