I did the Griffith uni Ba Avn. I enjoyed it, as others have said, each degree will have its strengths and weaknesses. Having done the degree and having worked in GA I can say that it will not help you get your first few jobs. It did however recently get me an interview with a large airline overseas
I did the degree because I was encouraged by my parents. I found that uni life was pretty cruisy and I made some great friends. After graduating I became interested in post grad study and I am now working towards a PhD with UNSW.
If you want a well rounded education and the proven ability to think critically, go with a degree and take a part time job (I went with security and crowd control).
If you want money on the side and a fall back option, go with a trade; or
If you have the cash, just get your CPL ASAP and get that first job...
That being said, most employers look at flight experience, whether you can sell yourself in an interview and whether or not get a good reference from your last employer. That is how I got every job I've had.
