You're making life very difficult for yourself if you want to do Eng/Law (based of recent posts) or Eng/Comm and THEN want to do UoM MD pre-req subjects. You might as well do Eng/BiomedSc (as suggested) or some other combination. It's also worth noting that all those combinations are 5+ years (Eng/Law can be over 7 years!), add on a cheeky MD to that and you're going to be in uni for a long time.
Honestly, from where I stand, it seems you don't have much of an idea with what you want to do with life (emphasised by your current signature which lists nearly every course offered haha!). That's fine but in that case I'd suggest starting broad with something like Comm/Sci and then pick, choose, and transfer depending on what you like and don't like.
I think you'd benefit going to Monash during Change of Prefs week and sorting this stuff out with people who deal with course planning.
