It is one of the longest jail terms for a rapist in Western Australia.

During the five-week trial, the district court heard the civil engineer used the internet to trap his victims.

Between April 2020 and January 2022, he invited 12 women on dates or to his house in Ascot, Perth, where he assaulted them.

Two of the victims were 17-year-old school friends and one was a 16-year-old girl.

Lusk was acquitted of indecently assaulting a fourth teenager.

Nine women were recorded, including one who could be heard pleading, “no”, “stop” and “please, show mercy”.

Ten of the victims were drugged with ketamine, Xanax or clonazepam, which the offender bought through the encrypted messaging service Telegram.

The 45-year-old claimed what took place was consensual and he denied spiking the drinks of women he had met on dating apps.

Lusk pleaded not guilty to a total of 100 counts, claiming the women were consenting and were either “lazy” or “role-playing” being unconscious.

He was convicted of 97 counts, including 85 of counts of sexual penetration without consent and 12 counts of stupefying in order to commit an indictable offence.
