I'm not sure what banner of aviation the RFDS fits under (GA or otherwise?) but I have a friend there who is on a very... Very attractive salary.
They're paying half his yearly mortgage.
Some 15-20k of his yearly wage is not taxed (due to working in a not-for-profit sector)
Super
And his wage on top of that- not bad if you ask me... And from what I hear, truly rewarding work.
