Personal opinions on studying Financial Planning, Financial Advising, Financial Management?

I'm currently in year 12 (I live in Australia) and I've had aspirations to study Beauty Therapy. Though lately, I've been developing more thoughts as to what career path I should really take. Thinking ahead, I'd like a career that pays excellent money, or even a substantial amount at the least. I don't want to be dependent on a man to bring home the big bucks.

I'm not an incredibly academic student, though I have a hard work ethic and I would consider myself as fairly organized. I have an interest in money and if I could somehow prepare myself to learn about the general background of finance, I would.

Problem is I'm not going for an ATAR, though I understand there are other pathways I could take to get into Uni. I could study a TAFE course beforehand perhaps and that may get me an entry as a mature aged student.

I'm just wondering what your thoughts are?

What is it really like working in the industry (specifically in banks)?

Is the pay within the financial sector as great as they claim it is? Does pay rise much with experience?

Is there much of a difference in these financial careers I've mentioned and do they pay approximately the same?

I have done my research, though different sites tell you otherwise and I'd like to hear it from one's perspective.

Thank you heaps!
