As per the CSU website:
Internal transfer pathway.
Selection for interview: Eligibility for interview is based on GPA in the year of application. Interviews may be granted to current Charles Sturt students who meet the following criteria:
- Enrolled in any Charles Sturt course at the time of application
- Have completed a minimum of 4 standard subjects (32 credit points) at Charles Sturt with a GPA of 5.5 or better at the time of application
The problem lies in the uncertainty within this statement of "may" be granted a 2025 entry interview. 2024 was the last year in which an interview was "guaranteed". They found that doing this, they had way too many interviews and ended up having to push the interview offers by a week and interviews themselves to December instead of end of November. My running theory is that they've taken out the guarantee to reduce interview numbers and to increase the number of rural admissions.
We don't have any history, precedence or data to go on for non-guaranteed spots. However, in saying that, multiple people have received a 2024 offer with 5.5-6GPA. The GPA threshold isn't really (as far as I can tell) a marker of rank, it's to make sure you're able to handle the caseload that comes with dentistry. As long as you can get to 5.5, they assume you'll be fine studying dentistry (b/c it no longer matters once you receive an interview invite - assuming it's still +5.5 at time of place offer). What's more likely is that they are looking for a higher rural intake this year and thus will extend offers with a preference for rural students (there is supposedly a number of places that is set aside for these students). They may start looking at ranking GPA to decide who gets the remaining interviews, but its hard to say without data.
TL: DR: 6.5GPA is a good GPA and competitive for CSU (it's roughly what I scored) and reasonably competitive for other unis as well. There should be no other considerations (except rurality). If in doubt, call the uni. Best of luck!
