Yea I'm also interested in this as well. From what I gather from other universities, they prefer to take in very high academic achievers who also achieved good UMAT and interview scores, but having said that, other universities who do not specifically have UAI/VCE other cutoffs just pick the top applicants.
Of course it depends on demand for the course, but assuming that dentistry has a similar proportional demand to medicine in terms of applicants to places, then the trend is that some people can get in with a relatively low UAI/VCEetc compared to the rest of the cohort so that the university can use them as an example to say that cutoffss are not the main discriminant. Also because if you get a low cutoff, (anywhere from 85-95) you can impress in the interview and still get in. But otherwise, getting a high score and good umat will usually guarantee a good chance.
I don't know of a specific number, but there will probably be anywhere from 30-45 places for this course (going by other dentistry schools in aus) for CSP and full fee paying, and you can be sure this is a very competitive course. You have to take into account that people who don't get into medicine may also apply for this course, plus the fact that there are only about 100-150 dental placings per year in the whole of australia, plus you compete with first year tertiary transfers, it is very competitive.
ps, to 'hello
' - is dentistry your first preference?
