Christy repeatedly punched her and wounded her with rocks then abducted her from the Loop, took her in his car to his home, and sexually violated her.
He switched on pornography on television before sexually abusing and threatening to kill her. After sexually violating her, he drove her to a city street and dumped here there.
A member of the public found her and called emergency services just before 7.30am. She spent days in hospital recovering from her injuries.
The Crown sought preventive detention which was opposed by defence lawyer Arthur Fairley who argued Christy did not have a history of sexually violating women.
Justice Christian Whata said he was satisfied, based on Christy's remorse and positive rehabilitative prospects, that preventive detention was not necessary.
Christy was given the first strike warning.
