I made my mind up to go because of the way the military (not just the RAAF) treats its people (including, but not limited to me).
As someone who has experienced a few years out of the blue uniform let me say that although the RAAF isn't perfect in how it treats it's people, it's not too bad either. Can't speak for Army and Navy.
I don't know your story Bung and you may have a genuine gripe, but beware of the "grass being greener on the other side" syndrome.
Seems nearly every reservist that I speak to who flies for a major carrier hasn't too many nice things to say about how they are treated.
