There's two different prices in WA, volunteer is $10 and the paid is higher, can't remember how much exactly. At least it was a few years ago when I was doing them!

All the men with responsibilities in our congregations now have to get a WWC, and if they refuse or don't pass, they're removed from their responsibilities. I thought it was strange when it came in, as they don't have any necessary contact with children, but better safe than sorry I guess.
