1. uq - has the best resources and best research out of the three, plus it has the "tradition" thing, and its a nice uni environment
2. qut - plenty of different courses, but its like cramped in there...
3. griffith - its alright...
but really, it also depends on which course you want to do
ive been on a work experience with boeing and this is what they told me is in the aeronautical field
its mainly split between avonics(electronics like nav and GPS), struture(design of wing etc.) and mechanical (engines etc.) a aeronautical course is mainly split between avonics and structure...
