Melbourne Classes / Agencies

Hey, I know there are a lot of threads on here, I have done a search to no avail, Please recommend me a good acting class to do this year, I am first year uni so whats the best course (short curse or part time) to build skills in acting for tv/ film. Also what would be the best agency for me to try to get into at the end of this year, im 17, singer for 11 years, dance (jazz) for 2 years but im fairly new to straight acting, ive done music theatre before. Thanks!! Much Appreciated!! Bianca
