UNSW 10 week

RMIT 10 week

Adelaide doesn't have to understand the language.

University of Queensland 10 week

After reading the language, you can directly enter the above universities without taking IELTS. But this is only from the perspective of language. As for your undergraduate grades, I don't know yet. Therefore, there is no guarantee that you will enter these schools, especially UNSW.

When you say preparatory courses, you mean language courses, right? Your IELTS score can be promoted directly, so the answer is relatively simple. Because the IELTS requirement of the University of Adelaide is 6, and the single item is not less than 5.5, there is no need to read a language.
