Australian Finance and Banking student in uni adelaide

Hey mate, I'll attempt to add some colour on these points but keep in mind this is coming from a fellow student.

I'm not entirely sure what you're referring to by "financial analyst", I'm assuming you've seen this listed as a career possibility on the uni website (please correct me if I'm wrong). IMO financial analyst isn't really a career itself, but more a category of careers in which I'd say investment banking would be included but would really include anything that involves, as the name suggests, financial analysis.

A Master of Applied Finance will not guarantee you anything, GPA is always important (as is experience and extra curriculars). I'd personally pick up another undergraduate degree in something like maths/comp sci, law or economics instead (even honours). At the end of the day, the only advantage these provide are giving you more time at University to accumulate experience and extra curriculars which help you secure a "better" internship and grad job (from my understanding at least).

I don't know much about applying for overseas opportunities. From my knowledge it is only viable for people who have citizenship in one of those countries mentioned (so visas don't need to be sponsored) and I don't know about having a better shot. I'd say local candidates would be favoured. While Australia does have a comparatively smaller finance sector, I wouldn't let that deter you, still plenty of opportunities.

I know very little about stock broking, so can't really help you there sorry. I'd say getting a grad job would be less structured than investment banking or big 4 and there could be less demand? Although I really don't know. Maybe look into wealth management and financial planning related jobs and opportunities?

I'd highly recommend poking around the page "Corporate Finance Institute Career Map" and having a look at all the careers associated with corporate finance to get a feel for the different career possibilities. Also reading the breakdowns on "Mergers and Inquisitions" for the different careers (keeping in mind they are very US centric). There is a podcast called "Graduate Theory" (actually run by an Adelaide grad) who did an episode called "on the journey to banking and consulting graduate roles" that gives some good info on getting into investment banking and consulting in Australia that's worth listening to if you're interested in those paths. Viewing people's LinkedIn is also great for seeing what experience others had.

To avoid too much rambling I'll wrap it up there. Feel free to ask anything else/clarify any of your points and I'll try my best to answer them.
