Hello and congratulations on completing VCE

Last year I was also wondering about this as Monash has a 'guaranteed entry' for Science and Arts if you get an ATAR above 75 with certain SEAS categories. I emailed Monash because I was thinking 'what if everyone this year who wants to do science at Monash gets above 75 how can they fit everyone' however the Monash staff who replied to me confirmed that if my ATAR was over 75 I would be
guaranteed a position (I still continue to question this).
I can't confirm that you will be able to get in but I can tell you what happened to me.
My top preference was Psyc(Hons) at Monash which had a clearly in of 87.2, I was quite a few points below this however I had two SEAS categories which lead to my Monash adjusted ATAR to being 88.35 (I'm guessing, according to the Monash SEAS calculator) and that allowed me to get into the course.
From what I experienced, I am guessing that your SEAS ATAR is viewed as a normal ATAR by Monash, for example if someone received an 82 (no seas) and someone received an 81 (with 2 SEAS points), that 81 would be viewed as an 83.
I am not 100% sure if that's how it works however without my SEAS I would not have been able to get into my top preference.
Good luck with everything
