Whoever gets waved through the fast track line is not up to the flight crew. The decision is solely on the customs officer on duty. The flight crew were lucky, not arrogant.
Please stop bashing the pilots. Everyone is tired after that flight, it is not the pilots fault that the cabin crew did not get expedited.
I have been in the line with the rest of the cabin crew and customers many times in BNE. I do not agree with the policy as the majority of airports in the world have crew channels. However, the crew looking after the likes of you have worked through the night (on certain BNE flights) and the last thing we need is to stand in line wasting our already measely rest time before having to move on less than 24 hours later. If we get waved though, we are not going to turn it down just so some frustrated pax can dump their emotional baggae on us.
I apologise for sounding rude to your post but I am merely returning the same courtesy you displayed to the pilots.
