Coming in with very limited knowledge and having spoken to a few FAs on various airlines (MH, SQ, TG, 6E, QF, UL) - I think it comes down how the crew is tasked? Some airlines (MH, UL) start/setting up to heat their meals or have drinks set up when the crew board the flight (way before pax even start trickling down the aerobridge). Now I'm not sure if QF does not do this - so I can't say one way or the other.
Also, another point that was discussed was that some airlines give crew a target (sort of aim for the flight service etc) that focusses on customer-first approach, trying NOT to say no as often, being able to think on their feet during service etc.
Also, what I have noticed with UL, at least, is that the crew is quick on their feet - sprinting across aisles to do service and somehow keep their composure, do the right things by the pax etc. I was on a UL international flight a few weeks ago, it was very light loads and I got to chatting w/ the CSM, who explained that their staff are trained to be quick, yet efficient, not leaving any aspect of the service component undone etc.
Again, not saying that QF does not do the above - just that I don't know if QF does this or not. I have not seen QF service to be quick on their feet - that is for sure.
