Hello Laura
You probably would have gotten the job by the time you see this message and therefore my comments will be irelevant.
There are lots of junior physio jobs in France, with some junior salaries as I've heard, starting from 4000-6000 euros. So if you're brave enough and ready for an adventure why not give it ago.
I qualified in the UK in 2007 as a physio, my husband is French so we moved to France after my studies. After 6 months of learning the language (which is far from perfect) in the first week of looking for a job, I got almost all the jobs. I had to choose which one I wanted to go for. I'm also due to change jobs and I have a couple of offers awaiting me.
You may not have the luxury of having 6 months to learn the language but I think you'll learn on the job. There's a real shortage of physiotherapists (known as Masseur Kinesitherapeute in France).
Of course moving might not be as easy as it sounds with lives commitments in mind. Good luck. If you're interested and you need help regards to how to register here and any other details I am very happy to help.
