Great info here thanks all, I'm currently in the same position as Gemmy having to pick between the 2. Had always had my heart set on tower but really dont think I could risk heading to karratha or tamworth (got my boot scootin fix on raaf pilots course!) for 3 or more years. Sounds like its more difficult to get tower from enroute rather than the other way around but think I may have to take my chances.
