Hi there kiko98.
I'll also be doing the Bachelor of Biomedicine this year! Unfortunately, both Mathematics for Biomedicine and Physics for Biomedicine (and its advanced equivalent) at set in stone. You cannot simply avoid them.
Just for your own understanding, you will still be required to do the GAMSAT to get into post-grad med if you're doing a Bachelor of Biomedicine. You don't get in through your marks and interview alone. As a result, it is inevitable that you will need to do Physics at some point as it is necessary for the GAMSAT.
If you choose to do the Bachelor of Science instead, keep in mind that there are equivalent subjects that you will need as prerequisites to get into the MD. (edit nvm the following!) These include prerequisite studies in 2nd year anatomy, physiology and biochemistry. I don't think you actually need to do physics subjects in this pathway, but it would mean you need to self-learn physics for the GAMSAT if you chose not to. Someone else more experienced with it should be able to clarify if this is right, though!
