How to enrol children in schools in Adelaide without address?

Hi, We are currently living in Abu Dhabi and planning to move to Adelaide in Dec 2016. We have Parmanent Visas (subclass190). I have three kids. How can I enrol my kids in schools, prior to our move, without having any residential address in Adelaide? As the schools are zoned there. I want my kids to start the school in Feb 2017.
