I believe that while they may weight ATAR and written application “equally” it is much easier to distinguish oneself from other applicants with a strong written application than a few ATAR points, i.e. the written application is scored in a way that creates more variation among scores. There is no specific ATAR requirement for this reason - someone with a perfect 99.95 could (and this happens every year) miss out on a spot if they have a poor written application whereas someone with an ATAR on the lower side (I believe some people with ATARs as low as ~90 [lower?] have received offers in the past) could still be competitive if they have a great application. As a rural applicant, you will receive bonus points when you apply, but this will be even more advantageous if you can relate your rural experiences to why you are interested in a course with such a strong focus on rural / indigenous health in your application. Good luck.
