That may be the case in the UK but it means nothing in Australia. Personally, as a professional pilot, I couldn't imagine anything worse than working in another field of aviation where I didn't fly. There are loads of good uni's with related courses that will be recognised by other sectors. The aviation degree's may help you with a post grad but from my understanding don't hold much credit and certainly don't hold their weight outside of aviation. You must research this before you apply.
