I think as a current student in an Australian medical school, I can give some input. I wont disclose which school I am attending, as that will give away who I am, especially because I'm the only "Khanna" in my school.
I went to college in the US, and was in one of the top bschools in the country and graduated with a major in business administration. Our school had a "premed" minor available, and thus that was my minor. I graduated with a GPA of about a 3.5, and an MCAT of 31, and came to Australia for medical school. I did not apply to Carribean, and quite frankly dont know much about it other than the negative stigma and publicity it gets but to be fair I cannot give you a comparison on whats better, as my knowledge of Carribean schools is very limited.
But I just finished my third year here (in a 5 year degree program), and have just completed Step 1 and plan to take Step 2, next year at this time or early 2014 before year 5 begins. My Step 1 score was much lower than I had hoped for (227), so I hope to do better on Step 2.
But regardless of my disappointing performance on Step 1 (as my class average is near a 235), coming to Australia was the best decision I have ever made. I made friends of a lifetime, the country is just a joy to be in, and the scenic beauty is second to none. Majority of these comments that have been made are correct. You really have to put in some independent self-study time for the USMLE. At least in my school that was easy to do, as we had all purchased Board Review Series USMLE books and used it as a primary textbook for our courses, and we went way beyond what our professors required us to know for exams. In a way that really helped us, but it needs self-discipline. The australian preclinical curriculum is not adequate enough for the USMLE.
The diversity in my class is absolutely stunning. We have students from all over the world who were very accomplished, as well as native Australians who were the most brilliant students in their graduating classes. But contrary to what you would think, our cohort is probably one of the most social medical classes in the entire world. We have 3x annually campus wide festivals, performances as well as the biweekly social events the school sets up. There is no denying that studying is quite a lot, but there is still ample time to involve in activities, and again if your goal is to take Step 1, you will be quite busy studying majority of the time. But studying for Step 1 has a direct translation to school performance, so the professors know the US students as the academic overachievers which is a motivator by itself to study more
Having finished half of our clinical clerkships, our hospitals are quite amazing with ground-breaking technology and sanitation and prevention being the highest priority of our hospitals. I will finish the other half of our clinical clerkships in year 4, and year 5 is primarily reserved for electives and a quick rotation in emergency medicine. Our school gives us the opportunity to do electives anywhere in the world, including the US. The US offers electives for international medical students still currently in medical schools at select locations. Upperclassmen have done rotations at Cleveland Clinic, Mayo Clinic, Mount Sinai, Penn, Uchicago, and some others which I can't currently recall of the top of my head. These electives, you get a grade for, and is actually a clinical clerkship similiar to what US medical students complete in their 3rd/4th year depending on their specialty they are interested in. This is different than observerships. I actually plan to do a research elective rather than a clinical elective, as I'm interested in research and plan to continue on my research which I started in college regarding Malaria in pregnancy. I'm actually leaning towards doing a research elective in a university in Cape Town, but social pressures are pressuring me to do a research elective in the US instead, so lets see how influential they are
We've always had an impressive match every year from students applying to the US, with a 100% match rate since my first year. The most impressive last year was a US Citizen getting orthopedic surgery at University of Alabama, which is known for having one of the best ortho departments in the United States. This is just one out of many decent matches, but wanted to mention this one as this match will not be forgotten in a long time.
Australia has been a great experience, and I'm torn everyday now between whether I want to return to the US or stay here in Australia for internship and residency. Its a great country (minus the expensive cost of real estate here which is a strong enough reason to consider returning to the US). Admission is very competitive. It is truly a "bread and butter" kind of admissions policy, where extenuating circumstances at least are not heavily looked at, and at my school a masters or PhD GPA is not considered. While the MCAT is not required at my school, its heavily recommended for applicants not having a 3.75 GPA. But then, having a GPA of about 3.75 and having some research experience, or having a GPA of 3.4 and an MCAT score of 29+ is nearly a guarantee you will get in, so not having medically relevant experiences is no biggie if at all when it comes to admissions.
You'll have a great time here, a great educational experience here, and most importantly you'll make friends of a lifetime. If you have any questions, please feel free to PM me
