Yes, ACS is the only recruiter for RMIT flight training at YMPC. I inquired about the position as a Ground theory instructor they had up on AFAP about a month ago I recall???
peterc005 has pretty much summed everything up.
I've personally trained their and was vastly pleased with the training compared to Swinburne. Facility, flight training are great, and shops aren't that far from the building.
Students will always find themselves in difficult situations. Personally I've never experienced anything dramatically, my flight instructors were upfront and experienced from the outback. Though I have heard stories and witnessed them myself on occasions. PM me if interested!
Cheers,
