Looking for a host family in Australia

We are looking for a host family for my daughter. She has dual citizenship (German/Australian)and lived in Germany most of her life, therefore we have to organize everything privately. Sally wants to spend 2-4 terms (2016/2017) in Australia, she will be 15 then. Her favourite high school is Kingscliff/NSW, so we are looking for a friendly host family in that area. Thanks in advance!:grinning:
