kido525 - I'm not really sure how easy it is for Med Sci graduates to find work opportunities and what the average annual salary is. Try looking in the Job Guide 2005 -

Med Sci can lead you to a career in medical research for private companies and hospitals or you can use it as a stepping stone to pursue a degree in Medicine, Dentistry, Pharmacy, Opotometry, etc. UWS doesn't offer any of these courses but I think there will be a new medical school in UWS starting in 2007.
If you wanted to become a Pharmacist, for example, you could either complete 1 year at uni AND have at least a GPA of 6 (Distinction) or higher and then apply to transfer to another uni that offers Pharmacy. OR you could complete a full degree with at least a distinction average and then apply. There are also other requirements such as the STAT test and sometimes an interview.
Here is some info from the Job Guide:
Employment Opportunities:
Most medical scientists work in the health industry, especially in hospitals. There are also employment opportunities in universities and research organisations. Limited opportunities also exist in the private sector. There is a relatively stable employment base in the public sector because of government responsibility for monitoring, testing and maintaining health standards.
It is a large occupation with very good employment prospects. Factors that may affect employment include the number and type of tests required to research, diagnose and treat diseases and the incidence of new diseases.
