Who is The Fortune Teller from Mutant Message Down Under and what is their importance?

This mysterious individual appears in a café where Marlo is to meet a friend and colleague. He reads her palm, and tells her she's about to encounter someone with whom she shares a destiny. At first Marlo thinks nothing of their conversation, but later when the same message is offered to her by different Aborigines with whom she's on her walkabout, she realizes that the fortune teller's appearance in her life was something more than just a random occurrence. She comes to understand that it was, in fact, a manifestation of the Real People's belief in the way all things and all people are connected.
