As much as I would like to help you because I admire that you're interested in a piece of formal academic work, I can't because it's a whooping
67.53 god damn megabytes (or at least the version in the eLibrary is).
According to
the library, non-USYD members can gain access by visiting the library (I presume Fisher; I'm not 100% sure how this kind of thing works, but apparently it's possible).
Or better yet, try contacting the man himself. I found his LinkedIn page easy enough, so tell him who you are and that you're personally interested in reading his thesis, and there's a good chance he'll give you a copy.
Good luck!
