A man who claimed he was possessed by the spirit of his ancestors when he raped a Dutch backpacker he kept in a "private hell" in a Melbourne hotel room has had his jail time increased from 17 to 23 years.
Alfio Anthony Granata, 48, brutalised the 21-year-old woman for six weeks in 2012 until she escaped by stabbing herself and forcing her tormentor to call triple-zero on Christmas Day.
Throughout the ordeal, Granata told the woman he had killed many people and had never been caught because he was "very clean and precise".
He whipped her with a mobile phone charger and used a jet lighter to burn her hair.
Granata's crimes were "extremely depraved", the Victorian Court of Appeal said on Monday, when increasing his maximum term by six years.
His non-parole period has been extended from 13 to 17 years.
The victim had willingly gone to the Preston hotel room with Granata and his girlfriend in early November 2012 to smoke ice and have consensual sex.
Granata turned violent after becoming convinced the victim and his girlfriend were having sex behind his back.
On one occasion he pushed a large kitchen knife against the victim's throat, then used the blade to scratch a cross into her forehead, telling her she belonged to him and was "marked for death".
While in bed with both of the women on a separate occasion he slammed their heads together, breaking the victim's nose.
Granata said he was possessed by demons, the spirit of his grandfather and an ancestor named Toto.
After six weeks, the victim was convinced she was going to die.
When Granata fell asleep she stabbed him in the shoulder, then began cutting herself, drawing enough blood that Granata and his girlfriend called triple-zero out of fear she would die.
Medical examiners identified more than 50 injuries on the victim.
Granata was jailed after he pleaded guilty to nine charges of rape, one charge of intentionally causing serious injury, two charges of threat to kill and other assault and drugs charges.
The Director of Public Prosecutions appealed the sentence on the grounds it was manifestly inadequate.
The Court of Appeal upheld the application and re-sentenced Granata saying he'd humiliated and dominated the victim during a series of distinct and grossly abusive episodes.
