My experience is mainly at Moorabbin, where I have hired a lot of planes from GFS/Oxford.
Looking back, I get a very favorable impression of the people who have been thru Swinburne/Oxford.
Can't comment on RMIT or other places because havn't had much to do with the.
Possibly the Swinburne/Oxford pilots would have turned out well anyway, but I'm impressed. Certainly the "airline pilot sausage factory" holds water, but that's what both the pilots and airlines want.
My strategy is for my son to finish his PPL in my plane before he hopefully starts at uni, and to use my plane as far as possible for training to reduce the costs.
Aviation degrees are a fantastic idea and generally seems to have been well executed.
