I'm sensing that some of your post might be sarcasm simpak (I'm so bad at detecting that stuff online haha!), but there is probably some truth in that. And I think that's fair enough in the fact that the vast majority of Biomed/etc students wanting grad med would be aiming for the UoM MD (good rep, good location, big-name hospitals, etc), but I still would move to Monash if I was in a position (like a lot of UoM Biomed students) where I had tried to go for undergrad med (ie. Monash mainly) and failed to get in.
You can still aim for UoM MD at Monash, and I'd say the vast majority of Monash Biomed students aim for the UoM MD too. It's just that you'd have a higher chance of medicine at another uni too.
