A victim of child sexual assault has told a court how he has been ostracised, bullied and intimidated by the Orthodox Jewish community for reporting his abuser to police.

The man, now a 38-year-old married father, was 14 when he was indecently assaulted by Daniel Robert Hayman at a yeshiva camp at Stanwell Tops in the 1980s.

Earlier this month Hayman, a dual Australian-American citizen who lives with his wife and children in Los Angeles, pleaded guilty to indecent assault of a child under 16 and under his authority.

On Tuesday, the victim, who cannot be named for legal reasons, gave a victim impact statement detailing the effect the abuse has had on his life.
