A know a guy that is working as a Financial Analyst for an investment firm in Sydney. He recommended I do a Graduate Diploma in Applied Finance and Investment. I’ve done some reading up on it and it looks like just the thing I’m looking for.
Advice that I have received on this goal was to avoid the seminar-style courses and aim for the courses that industry professionals use to either get qualified or to further their career.

This goal may well tie in with my other goal of choosing a new career path. I’m happy to consider doing this course for now. Even if I decide not work in the finance industry I’ll still have very valuable skills for managing my own investments.
