MELBOURNE (AFP) - An Australian man raped his daughter almost daily for 30 years and fathered her four children, a report said on Thursday, drawing chilling comparisons with Austrian Josef Fritzls incest case. The man, aged in his 60s, began molesting his daughter in the 1970s when she was 11 and continued until 2007, Melbournes Herald Sun newspaper said in an exclusive report. Victoria police refused to confirm details of the case, saying it was under a court order banning reporting of proceedings and identifying the accused. The Herald Sun said the daughter was kept a virtual prisoner in the family home about 100 kilometres east of Melbourne, without giving details. Local media made immediate comparisons with the case of Fritzl, who was jailed for life in May for holding his daughter as a sex slave for 24 years in a cramped, windowless chamber and murdering one of their seven children. The wife of the accused, also the victims mother, denied any knowledge of the abuse, the Herald Sun said, adding neighbours and child welfare authorities also failed to act on suspicions about the man. We lived in a big house, so I wouldnt have known, she told the newspaper. He had a very sharp tongue. He was a drinker. Victoria state Premier John Brumby said the full force of the law will be applied, acknowledging there would be questions about why the alleged abuse was not detected earlier. Obviously any crime of this type is one that is shocking and that is personally repulsive to me and to other Victorians, he told reporters. Its a terrible case. It brings to all of us I think the worst possible thoughts about families and what might occur there and what may have occurred. Police will reportedly use DNA evidence to prove the man is the biological father of his daughters children when the case goes before the courts in November. The Herald Sun said all the victims four children were born with birth defects in major Melbourne hospitals. One of them, a girl, died as a result of her health problems. The victims mother told the Herald Sun her daughter would clam up when questioned about who fathered her children, giving vague answers about meeting men in nightclubs. She described her husband as moody and abusive but said she never suspected him of sex crimes. The report said the victim went to police in 2005 after a neighbour urged her to take action, but then refused to cooperate further because she feared for her safety. However, she returned to police in June last year and gave a statement, the newspaper said. Police conducted DNA tests on the father and charged him with sex abuse in February. One neighbour told the paper that she had suspicions about the man for at least four years but took no action because she did not want to interfere. I didnt go to anybody because it wasnt anybodys business, she said, accusing the woman who encouraged the victim to report the crime of being a busybody. The Age newspaper said the man initially faced 83 charges but they had since been reduced to 13, including five of incest, five of rape and two of indecently assaulting a girl under 16. It did not detail the last charge. He is reportedly in custody awaiting the November court case, while his daughter and her surviving children are in state care.
