I think the laws must be relaxed in NSW....
I do 2 childcare centres and i've never been asked to get a check done. My wife does canteen at the school every 2 weeks and doesn't need one... the kids have a walkathon next wednesday and the principle asked my wife today if she can help with a check point (again, no working with children background check).
I also do a property where they have forster children... Doc's is there usually every 2 or 3 visit that i'm there and i've never been asked for a background check.
I've heard about people needing a check... maybe we do in NSW also?
Anyway, I try to do the childcare centres afterhours as it is easier and quicker to do... no one in my way!
Simmo.
