Dokic, who moved to Australia with her family when she was 11, has previously alleged that her father physically and mentally abused her regularly throughout her career, starting from the moment she picked up a racket at six years old.
"Every morning, I woke up and thought: 'How do I make sure he doesn't hurt me today?'" she says in the film.
