Hey Matt, I'm first year in the JMP so I can't give you a huge amount of idea about the clinical placement stuff later on but I know about the pre-clin side of the course pretty well.
Overall I'm really happy and echo Dr Worm's sentiments - there are sucky parts about the course but they're largely trivial and certainly not worth you discounting the JMP as an option. I really enjoy how much it's self-directed and I'm given a lot of freedom to do what I like when I like. With that, however, comes a lot of responsibility to make sure you get things done - we get examined on things which NEVER come up in class and the faculty don't give a crap if you have a problem with that. A lot of people are struggling with this but I actually really love the autonomy. It also means we haven't got a huge amount of class to attend - 15 hours a week in first semester then about 10 on average from second semester first year. This works really well for me because I have to work to support myself and it makes it easier to juggle work, study and having a life.
In terms of early clinical exposure, UWS definitely pips us. There's a tutorial once a fortnight in first semester then from second semester we have to get over to the hospital for self-directed clinical practise - this semester we have to go and practise taking histories but I know in later years they have to practise exams and such on patients in the hospitals. I definitely don't feel like I'm missing out on clinical exposure though and it increases over the next two years then full time in the hospital from 4th year.
A quick note on UTAS - Launceston and Burnie are both around 4 hours drive from Hobart so it's hardly a commutable distance in your clinical years.
Whichever uni you end up at, there is a VERY high likelihood that you'll have to move
at least once for your studies and this by no means ends when you graduate. You'll have to move to your internship hospital and then depending on where you choose to go from there you're likely to have to keep moving around for a few years at least. It's just a part of life in medicine and there's no real avoiding it. As such, moving around for clinical placements is a little bit irrelevant when choosing between these three unis.
Let me know if you want to know anything else about the JMP
