It's dull as dishwater and will put you to sleep in minutes, but get your head into the Airpower Development Centre's doctrine books. Not all if them, just the key ones that talk about how Australia does airpower and where the RAAF fits into the overall scheme of things.
As I said, dull, but worthy reading if you haven't done it already as it will give you an insight into the sort go things you can expect to be getting involved in.
