WA police claim that between February and March this year, the 31-year-old met five women on various dating sites.
He is accused of drinking their drinks, whether at the venue or at his home, making them incapacitated before sexual assault.
The Shelley man has been charged with several counts of sexual assault without consent, drug intoxication, assault, drug trafficking and obstruction of another person’s normal breathing or circulation by putting pressure on his neck.
He is due to appear in the Perth Magistrates’ Court on Thursday.
