Clinical Placement Abroad

Hey All,
New to this! I'm going to post this anyways even though I see that not many people have had success with it in the past!!
Anyway, I'm a physiotherapy student studying in Dublin, Ireland. As part of our degree we can do a placement abroad! It'll be from June 2011 to the middle of July. It's 6 weeks in duration and I'll be in my final (4th) year.
I was hoping to go to Canada or USA but I obviously wouldn't mind New Zealand or Australia. I've emailed some clinics in Canada but to no avail as of yet!
Just wondering if any of you have done this in the past and if you know of any places which regularly take foreign students. I can work in clinics, hospitals, primary cares, private practices, etc. Can manage my own caseload and the works.

Any information would be great! I'm almost at the end of my tether!
Thanks in advance,
Robert.
