David Campbell’s mother is Kim Campbell , who had him as a teenager and was long publicly known in connection with singer Jimmy Barnes and their complex family story.

Kim’s mother (David’s grandmother) adopted and raised him, so for the first decade of his life he believed his grandmother was his mother and Kim was his sister, a truth he only discovered around age ten.

This family setup, and the later revelation of Kim as his biological mother, is something David Campbell has discussed in multiple interviews as a defining part of his upbringing and identity.
