Wei Feng prowled the streets of St Kilda over five years, luring sex workers to his car and violently forcing them to fulfil his perverse sexual fantasies.
He would promise to pay for each woman's services and then drive them to a dark, isolated area where he would begin his attacks.
Feng, 50, was on Monday sentenced to 14 years in prison for the violent rape and assault of three sex workers and another woman between 2013 and 2017.
Three of his victims were sex workers in St Kilda, whom he lured to his car and then forced them into having unprotected sex with him using weapons, including a meat cleaver, Melbourne's County Court heard.
Appearing via videolink from prison, Feng appeared irritated as he moved around the room and tried to interrupt Judge Frank Gucciardo during sentencing.
Judge Gucciardo said Feng had treated his victims with "utter contempt", using them to fulfil his perverse sexual wishes.
"You treated these women with utter contempt, you violated their bodily integrity, you humiliated them and subjugated them to your vile whims," he said.
"The fact that three of them were sex workers makes them even more vulnerable to your aggression and violence, exemplified by your expressed desire for unprotected sex and the threats which accompanied your violence."
Judge Gucciardo said Feng's worst offending was an act of stranger rape, where he kidnapped a woman walking down a street in Sunshine in February 2017.
Feng stopped his car in front of the woman, talking to her about cigarettes before asking if he had dropped something.
"As you stepped closer to the open door to look, you grabbed her left arm and said 'get in the car or I'll shoot you,'" Judge Gucciardo said.
After kidnapping the woman, the car was pulled over by police for a random check, with Feng telling his victim he would shoot her if she opened her mouth.
He raped and assaulted the woman several times, threatening to hurt her further.
Feng tied her hands together, but she freed herself after making noise and struggling. She refused to go to his house in Laverton and he unlocked the doors and let her out.
"This kind of 'stranger rape' is misconduct that leaves the community, and women in particular, in fear and consternation," Judge Gucciardo said.
In July 2021, a jury found Feng guilty of 10 sexual offences against four women, including rape, attempted rape and abduction.
The court on Monday heard Feng had tried to frustrate and delay the legal process by firing his legal counsel on several occasions since his arrest in 2017.
He must spend 10 years in prison before he is eligible for parole and has already served 1943 days in jail.
