Welcome to America! I have never been "Down Under" and want to have that experience. I bet your country is much safer as no one in America would dream of giving their 3 kids to a stranger from a foreign country they met on the internet even for just a trip to school!
A word of advice: DON'T DO IT! Way too much risk! You may never see your kids again! I am not an alarmist, but a realist.
If you do make arrangements, you personally take your kids to that school stay with them the entire time, and then you personally take them away with you. DO NOT LET YOUR KIDS OUT OF YOUR SIGHT!
