John Deaves married his third wife Dorothy back in 1984, but caused a public outcry in 2008 when it was revealed he had been having an incestuous affair with his biological daughter, Jenny.
The relationship started in 2000 after Jenny, who was 31 and married with children, had gone to stay with Dorothy and her then 53-year-old father in Port Pirie, South Australia.
Jenny had been estranged from John, only seeing him three times before 2000.
