Historically, GFS have never really had a need to "look" far for instructors, as they always have a ready-made pool of young hopefuls to mould in their own image (by way of the large numbers enrolled in the Swinburne/RMIT courses). The only time this is not the case is if they have a mass movement of senior people (as is about to happen quite soon), and they find themselves short of talent at the top of the food chain.
A lot of people bag this organisation (sometimes unfairly) for being a sausage factory amongst other things, but for the most part I enjoyed my time with them. As someone else has mentioned on another thread, most of the instructors are pretty good guys/girls, I have the utmost respect for the CFI (couldn't have worked for a nicer boss), but the owner... Well, I spent a long time trying very hard to get on his wavelength and figure out what makes him tick - but the fact is I just don't get him.
On the plus side: Good fleet, very high standards regarding SOP's and airline-style practises in general (as a result of their significant involvement with airline cadet training programs), and no shortage of flying opportunties.
On the negative side: A very insular place, more so for the guys who trained there, went on to work there, and have absolutely no idea that there's a whole other world out there; something to which the owner no doubt relies on to keep everyone on a tight leash (i.e. don't encourage them to think that there is actually life outside of GFS, otherwise they might realise they can do better).
