The only Australian pilots opposed would be a very few untravelled ignorant ones that have been brought up within "the local system." And of course, there is always one or two elderly airline gentlement scared stiff of ever getting a TCAS RA, not having the required alertness or reflex action to deal with it.
What about B200 (and similar) drivers without the benefit of TCAS?
Single pilot M/E IFR operations is difficult enough as it is!!
