For info, my experience as an S/O was 26 years ago in Africa, never flew for Qantas.
So, I guess I my comments have a bit more backing than some wannabe who appears to have gained his VAST experience during the odd stroll through the airport.
I'm not saying S/O is better than direct F/O. It is a great way to be inducted into an airlines operation with less stress for all involved. This is probably more beneficial for those with less experience.
