ofcourse there is a chance for you to get in, just meet the prereqs, 30 for both chem and methods.
With Monash and La trobe, they are well established and already have their reputations, whilst RMIT is still new ( first batch this year). Best to aim for the best, if you can get in Monash then do it. With the next two, I guess that would depend on the distance that you'd travel, or even move out. La trobe is in bendigo so you might want to consider that...
You can always transfer if you don't want the course, I assume Pharmacy is not an easy course, but if you are dedicated I'm sure it's well worth it, the money is ok, takes four years + intern ( paid), & effort is with everything you do anyways
There is boards regarding MedEntry and stuff, you might want to check it out.
