Relocating from Australia with secondary and primary children.

[aussiemumof3]

We have relocated our family and are looking to move to Kent or West Sussex (Tunbridge Wells/East Grinstead). 13yo needs a girls school, an 11yo boy with Aspergers in mainstream school in Australia and a 7yo. We know these areas because we lived in UK pre-children but any advice on schools, areas and how to navigate this system would be greatly appreciated.
