Police have continued their investigations since the 30-year-old man, who cannot be named for legal reasons, appeared in a Brisbane court on 10 charges in August.
Police appealed at the time for anyone with information to come forward, saying video depicting other women was found on a phone at the man’s Brisbane city apartment.
He is due to face Brisbane Magistrates Court on Thursday on a further 135 charges involving 31 victims of alleged sexual assault across southeast Queensland dating back to 2016.
The charges include 46 counts of rape allegedly involving 21 women, 38 counts of observations or recordings in breach of privacy, 14 counts of stupefying in order to commit an offence and seven counts of unlawful possession of restricted drugs.
The man is also facing charges relating to computer hacking, distributing intimate images, impersonation and stalking.
The alleged offences occurred in Bethania, Springwood and Brisbane CBD between 2016 and 2020.
Police have appealed again for more women to come forward saying they believe there may be more victims.
The man’s registration as a health practitioner was suspended by the Health Ombudsman about two weeks after his court appearance in August.
Police allege the man deceptively targeted his victims on social media dating sites.
“It’s also alleged he subsequently administered substances and filmed himself engaged in non-consensual sexual acts with his victims,” Detective Inspector Glen Farmer said.
Officers encouraged women who believe they may have experienced a similar pattern of behaviour to come forward.
“Detectives are continuing work to identify a number of women who they believe may also be victims of this man’s alleged predatory behaviour,” Insp Farmer said.
Earlier police alleged a woman in her early 20s met the man at a Mary Street apartment where she was assaulted after being administered a stupefying drug.
“She participated in a drink with that man and whilst at the apartment the behaviour that is the subject of the charges is alleged to have taken place,” Detective Superintendent Tony Fleming told reporters in August.
“There was an impact on her consciousness and after she was able to gather her wits she left and subsequently received some assistance from her family and also a GP.”
Police say they found several mobile phones, video recording equipment, and prescription and illicit drugs when they searched the apartment.
The court heard earlier police believe the sedatives the man used came from the southeast Queensland hospital where he worked.
He was denied bail during his first appearance with magistrate Anthony Gett saying his position as a registered nurse was concerning.
“It would seem … he has knowledge and training with those drugs said to be the administered stupefying drugs,” he said.
Mr Gett told the court he also had concerns about the method and nature of the alleged offences.
“The allegations concern a level of deliberateness and planning,” he added.
The court heard the man used social media platforms like Tinder and Snapchat to meet women.
