If you're looking for training other than Instructor Ratings I'd be inclined to wander next door to Goulburn Aviation. They've been operating in the Goulburn area since 1993 and the Instructors have a lot more experience under their belt. There seems to be a bit of a revolving door at GFTC - a past instructor tells me they've been through about 6 instructors in the past six months. Goulburn Aviation's training rates also appear to be quite a bit cheaper (and they use a Warrior instead of a 150). Goulburn Aviation also run the BBQ's on the first Saturday of each month as they're passionate about the social side of Flying also.
If you're looking to get an Instructor rating my personal opinion would be to go with an established and well-regarded school. All these things add up on the resume over time.
Best of luck with the decision-making.
