When applying for an undergraduate medical course you either apply to the university itself (University of Tasmania), or to a State/Territory Tertiary Admissions Centre (UAC/SATAC/TISC/VTAC/QTAC).
Applications for graduate entry medicine are processed by GMAC, a central body for administering applications across Australia. You can currently nominate up to three preferences from the eleven universities (although this is under revision) and can only be invited to one interview in each application period (per year) OR be considered by the University of Queensland which does not interview applicants. The exception is if you are an Aboriginal and Torres Strait Islander applicant who have applied through alternative entry schemes outside of the ACER application process, are offered an interview through this scheme in addition to an interview as a result of your GMAC application.
This differs from undergraduate medicine where you can apply for as many medical schools as you like, and can be invited to one interview per State/Territory (a maximum of five per year PLUS consideration by the university of Tasmania which does not interview applicants).
This is a major reason why undergraduate medical schools interview many times more candidates per available place than graduate-entry universities. For every ten available places graduate-entry schools typically interview 15 applicants, whereas 25 to 30 applicants would usually be interviewed for an undergraduate program.
However, this makes selecting your preferences for graduate-entry medicine a much more risky process. You will need to think about which university you would most like to go to and which university you are most likely to get into. You will then need to weigh up the chances of receiving an interview at your nominated universities, and if you get an interview, how likely you are to receive an offer. The universities where you are most likely to be offered an interview are not necessarily the same universities where you are most likely to be offered a place.
The answers to many of these questions will depend on your personal strengths and weaknesses within the application process – which of your GPA, your GAMSAT scores or your interview are your strongest components, as the different universities weigh each of these criteria differently when selecting applicants for interviews and for final offers.
It will also depend on the details of the admission criteria for Aboriginal and Torres Strait Islander applicants at the universities you are considering applying for, as some medical schools are likely to be more flexible to your needs than others.
It is very important to consider pragmatic issues such as where you will live, and what degree of financial, social and cultural support you will have access to in each prospective program. The answers to these questions will likely have a major impact on your final decision.
