There's another girl at my singing studio studying vocal studies at USYD. As AsyLum mentioned, the big difference is that USYD is very classically-based, so opera for vocals (no microphones permitted), piano, violin etc. Whereas MQ is very contemporary, so focus is on contemporary vocals, guitar, plus a whole bunch of music editing and music recording work with pro-level recording equipment on campus.
The Con is great, but is largely classically-focused with a big theory component so geared towards those interested in such a thing. MQ does have theory, but offers a variety of subjects that are literally about 95-100% practical.
In terms of fun and engagement, everyone I know who has done it (experienced musician or complete beginner) has enjoyed it immensely and many continue music studies far longer than the original elective-burner they thought it would be.
