Qatar actually has 4 schools supplying them with cadets: ST, CTC, FTE and QAC. Given their aggressive expansion plan, it is not surprising at all that they appoint FTOs from all over the place.
Comparing the program between CTC and ST, I stand more on CTC side. The school is run professionally, with very experienced ground instructors and flight training in an international airport environment makes them one up against ST. I know a few doing the Qatar MPL at ST and some of their feedback are: cadets are treated like trash, especially from the CGI who screams and shouts and runs the ground school like an army bootcamp. The marketing department is only interested in collecting fees. The flight training in Ballarat is chaotic with very little organisation of any kind. Students are often delayed due to poor planning. And because Ballarat is non-controlled airport, the cadets don't get to practice proper radio calls and are completely at a lost during simulator training.
In fact the reputation of ST is so bad that even CAAS questions students why chose the school over other school.
