Yay! You'll love it. (I'm jealous - I only have 2 days in France)

I can't speak from personal experience yet, but i've been told that the French are pretty helpful if you make it clear you're Australian (and not American or British) And even though most of them can speak English, they will pretend they can't unless you try some French first. Apparently they like to see you're making the effort, which makes sense.

I'll probably have some more first-hand advice in a few weeks!
