Where can I do a undergraduate degree in biology?

Hi, I am in year 11 in australia. I am hoping to become a doctor. I am planning to do medicine as a post graduate degree, so I am trying to decide what to do as my undergraduate degree. I think I should do something related to science as my undergraduate degree because the medical school will like that. I am really good at biology and want to do a degree in biology. I have been looking but I can't find any course in biology. I remember seeing a course in philosophy and biology which would be perfect. I am also interested in human behaviour, psychology, sociology, evolution, biology, etc and how they relate. I don't really want to do too much on chemistry or small, microscope things eg molecular biology, I like learning about the bigger picture. I would prefer a short degree ie 3 or 4 years, centered around biology. This uni course, majors degree, bachelor stuff is really confusing. Can someone help me out - help me find a course. I want to know the required uai as well. Oh and I really really want to go to a uni in sydney - sydney uni probably, maybe unsw. Thanks anyone.
