Some of the alleged incidents happened in Wollongong, according to police.

In September last year, detectives from the State Crime Command's Child Abuse and Sex Crimes Squad established Strike Force Honda to investigate the alleged sexual assault of a 24-year-old woman by a man known to her.

During the investigation, police received information relating to the alleged sexual assault of two further women - aged 19 and 21 - and two teenage girls - aged 15 and 16 - between August 2013 and March 2020.
