95 is a great ATAR and your parents should be very proud of you. Now to answer your question: DO NOT REPEAT.
There are many pathways that you can follow to attain your goals. Perhaps, you should sit down and ask yourself what you really want to do, what can you see yourself doing in the future? It is your life, and take full control. Don't let others drive you. There are a lot of options available, and believe me a GPA of 6.5+ is very much attainable by a 95 ATAR student. From my experience, I felt the same way last year. I really wanted to do medicine, but my ATAR was so horrible that it's embarrassing to talk about it. It was in the mid-high 80's range, and I was thinking of doing my HSC again at a different school. Yes, I went to a really crappy school (ranked 636/660 this year -.-). But I did not let my ATAR define my potential, and I put in average effort this year and attained a GPA of 6.4/7. Yes, it might not be enough for medicine, but doing a different degree has opened my eyes about other career prospects. Don't be afraid to take risks, maybe do a science degree that is more relevant to medicine. You could also do a completely irrelevant degree, and sit the UMAT. However, this wouldn't ideal if you're keen for GAMSAT.
If your parents really care about prestige, maybe consider a prestigious degree like Law/Science at UTS (you may get in with a 95 ATAR). But like others have said, it is your life. Do what you like and what you would likely succeed in. #YOLO
