A former Liberal MP will lose thousands of dollars after being forced to break a newly signed lease due to historical child sex allegations.

Roderick “Rory” Amon is accused of sexually assaulting a 13-year-old boy he knew on Sydney’s northern beaches in 2017.

The 35-year-old former state MP for Pittwater attended Sydney’s Downing Centre District Court on Wednesday, having entered a plea of not guilty to the charges.

Judge David Scully noted that the alleged victim described a potential relocation as “personally catastrophic” and expressed worries about safety due to Amon’s conduct over the course of the prolonged investigation regarding the complaint.

The judge denied the request to change the bail conditions, concluding that the likelihood of Amon encountering his alleged victim and causing psychological harm was excessively high.

The former Liberal MP would lose several thousands of dollars by breaking his lease, the court was told.

Amon has been on bail since he was charged in August, more than seven years after the alleged offences.

He is due to stand trial in the district court on 10 charges, including five counts of sexual intercourse with a person over the age of 10 and under 14.

He resigned from the NSW Liberal Party after the allegations against him became public.
