SCM offers a number of Graduate courses in Sound Production. It's generally desired that music managers have at least some background in music, which is why most tertiary-level music management courses are either at Graduate level, or offered by private colleges for far more than they're worth. Generally speaking, it's a good idea to either have a Business degree, or a Music degree - or at least a degree with either as a component.
JMC Academy and AIM offer sound production (electronic music, sound recording etc.) at Bachelor level, and are considered reasonably good courses. If your marks and your music skills allow it, the University of Western Sydney has a very good electronic music department.
