No, as long as you have at least 1FTE year of study I believe one’s GPA would be looked at the same as someone with a completed degree (but if there was a tiebreaker between two non-standards then the one with the completed degree would presumably be given the place offer). For the purposes of entry into JCU medicine your GPA won’t be converted into an OP or ATAR, as you’re in a separate applicant pool to school-leavers; the conversion would only happen for courses where you are competing for positions with other school-leavers.
Applicants can be categorised according to where they have lived (or in the case of JCU, where they went to school). An RA-1 applicant is someone who has lived in a metropolitan area for the majority of their life, an RA-2 applicant has lived in an inner regional area for 5 years consecutively or 10 years cumulatively, RA-3 = outer regional, RA-4 = rural, RA-5 = remote. RA ratings are assigned by the government based on the population size of the area; less populated = more rural/remote.
JCU applies a formula for place offers of rurality x ATAR + interview score to rank applicants for selection, so that an RA-5 applicant has a greater chance of selection than an RA-4 applicant, who has a better chance than an RA-3 applicant etc. (This makes sense as someone who has lived remotely for a significant portion of their life is much more likely to work rurally/remotely once they’ve graduated and thus address the country’s workforce distribution issues - this aligns with JCU’s mission as a medical school).
