Altho I don't have advice on what uni you should choose, I'll tell you why I came to end up choosing biomed science at uts.
Biomedical science at UTS is actually my first preference and it's something that I really hope to get into. I'm hoping to get into a career in diagnostic medical laboratories which was why i chose this course. I actually wanted to go to Usyd so bad because of how it looked and since some of my friends will be attending there. However, it didn't have any science courses like biomed and only uts and few other unis have it. Cuz my desired career involves a lot of practical work in the labs, uts has the best equipment for it and yuo get to do a lot of practicals, and it's good for employment since you have that ability. I'm not sure if UNSW has it too.
That's all I know tho
