Dd initially moved in with a friend and friends mother. I found out within a few weeks it was actually a boarding house, so alerted the authorities that she was in potential danger and tapped in with a youth agency in the area. They arranged accomodation for her with a lead tenant in a supervised house. She is doing VCE and determined to stay at school and it was deemed in everyones best interests at the time. It has worked out very well as the house is practically next to the school. There would be nowhere else for her to go otherwise.

Your DD won't be eligible for this scenario though, as there are no 'family problems' iykwim. She won't be eligible for unreasonable to live at home UNLESS it's because you are moving more than 90 minutes from her school . I still think it goes on your income anyway so that's out for her. And you aren't kicking her out either, and she isn't at school anymore (?)
