Ok thanks
1hr pre and 30 min post
planned departure DFW = 0145 UTC
so clock starts 0045UTC.
arrival into NAN 1510 UTC
departed NAN 1712 UTC
At this point of departure from NAN at 1712 UTC, pilot hours = 1hr + 15hr27min = 16hr27min
That leaves 3hr 33 min left on the clock (assuming 20hrs is the absolute hard limit)
Take away 30min for post flight at the other end. That leaves 3hr3min to arrive into BNE.
NAN-BNE is usually 3hr50min
BNE would have been impossible from the start.
They were short of around 45min but assuming no delays at BNE.

NAN-AKL = 1161nm
NAN-BNE = 1465nm (+304nm)
NAN-SYD = 1712nm (+247nm)
Planned departure from DFW 0145 UTC and arrival at AKL 2006UTC = 18hr21min
Add in 1hr30min for pre and post =
19hr51min for DFW-NAN-AKL
Im assuming they were legal into AKL
Did they decide to head for AKL before or after departure from NAN?

B789 VH-ZND Hard to imagine that the plane was properly cleaned in such a short time.
The short ground time in SYD could be added to the ground time in BNE before QF55 BNE-LAX as no passengers were on the SYD-BNE ferry. Do a bit in SYD and do the rest in BNE?
