As instructed by the company you can delay APU start till approaching the gate, shutdown the APU during a 40 minute transit, stay on ground power till 5 minutes to push, meet the COBT for departure to Sydney then fly an efficient altitude and speed schedule.
Then blow 3 ton of fuel out the tailpipe holding at CULIN for 45 minutes on a CAVOK day.
Passengers miss connecting flights, crew & airframes are under utilised.
I would say Sydney airport is a joke 24/7, but it's closed 7 hours a day.
