I was listening to ground frequency when they started taxiing in to
the bay, They stopped on the taxiway because at bay53 they had no ground power so they had to get a machine to supply ground power
to the aircraft at the gate.
As for the turn around back to sydney reason i heard the Pilot on ATC saying something to do with a having only 1 Generator and the eletrical systems, but maybe AJ or someone who has knowledge
about the 767 could say more.
and i believe Jackpot 9600 departed on 34L
