The numbers you're quoting are off for current-entry USyd students. Right now, the tuition is ~$66K/year (and growing) + living/books/travel. You're looking at at least $80K/year AUD and that's if you're conservative. This is the one biggest reason I didn't go to USyd... it's simply not feasible for those without very well off parents. Banks will give you up to $150K, but they will not go over that. Add on government loans and the best I've been able to get is $180K. Mind you, Flinders tuition is $43/year AUD. So it's must lower than USyd (this is why I'm going to Flinders... along with better internship chances, but that's for another topic).
If you want to go back to the US to practice, go the Carib. They will teach you specifically for the USMLE and you will get all your clinicals in the US. Plus, it will be significantly cheaper than going to USyd. Also, with your current marks/grades, you may be able to get one of those SGU scholarships.
In all honesty Raigon, I think you need to do more research on your own. It does not appear that you have clearly sat down and thought through what will be required of you with respect to finances, time commitment, etc. Yes, being a doctor can be a dream, but you need to look into feasibility. I highly highly recommend you go to that posting I told you about (Australian Medical Schools) in my blog and go to each of the schools' websites. Also, there's a post about getting loans. Read those and try to get answers from the horses mouth before trusting what people here post (not that what's been posted thus far has been incorrect - just get it from the source to be 100% sure).
As for residencies. The way it works in Aus is you do a 1-2 year internship after medical school (paid) and then apply to a specialty college for a 3-7 year residency (FM on the low end, surg, etc on the high end, also paid). The pay for these training programs is good and after your internship, you can do locum work which can be quite lucrative. The debt will be staggering, but it's not impossible. Your biggest concern should be getting the loans in the first place, though.
If you mean the Dr. Polar Platypus blog, I already read it. It has Canada, Australia, but I'd like to return to the States if possible, but there has not been any entries from Australia back to USA. You said you'd add that entry like... months ago. And currently, getting into medical school is very near impossible. That's why I'm thinking of Australia if I seriously fail. I have thought about Caribbean Medical schools, but they are looked down upon for residency programs, no matter how well you perform, which is why I won't do it unless I have no other choice.
I understand the path to being a doctor. Otherwise I would've chosen another profession. I know the road is very long and hard, but I chose this over other professions because I want to be a doctor. I've always planned it since high school. Had it not been that my dad relocated to Taiwan, I would've generally entered college, go to premed, take the MCATs and apply for Medical School. Get loans, enroll, then take the USMLEs and then in the final year, take the NRMP. Get into a residency program, then do a further 3~5 year specialist training. Get the big bucks rolling in, then pay off student loans. So commitment? I've planned everything out since like... 6 or 7 years ago.
Too bad after my dad relocated to Taiwan during high school, there was a big change of plans. Now I'm forced to consider an alternate route.
And if I must go to Australia, I'm going for a medical school that US fed loans will loan you money: U Queensland, U Syd, and Flinders. Just not where where I'll get the loans for the extra money. U Syd has the best reputation amongst Australia meds, but it's expensive. Next would U Queensland with its new Oscher Program, but it's new and may not prepare you well for USMLE. Also, it's not AMC approved yet. Flinders, everyone says it's good, but there's no specifics - are their lectures even partially USMLE oriented? How well do their students do in the matching program in the US? Well, in the off route that I decide I love Australia, I'll stay there, with a permanent residence, and then apply for citizenship if possible. I'm NOT returning to Taiwan.
I've sent emails to their schools, got a few brochures, read through some. I emailed Flinders and they like me. They say with my 30Q and my 3.89 GPA I'm a solid candidate to be short listed for an interview.
Because I've found out after I submitted my AAMC application that most schools don't accept overseas degrees or coursework if you don't have at least 1 year of formal undergrad in the United States, I don't think I have much chance. So right now, planning alternate routes is essential. I've already narrowed it down to three: Australia, Caribbean, or Post-bacc in the United States from most preferred to least.
And now... the countdown to next may in the highly likely event I fail to make it to a medical school in the United States, Australia, here I come.
