Clif's dashboard

I went to Australia on vacation last month and bought a couple of games - only to find out that they do not work with USA version wii. I had no idea.

Anyway, one of the games that I purchased was the wii fit with balance board. I was wondering if anyone knows if the Australian balance board will work with my wii? I would rather just buy a new wii fit disc than try to sell the entire set up and replace it. I live on a small pacific island so it is hard to get games.
