The Adass Israel School sex abuse scandal is a criminal case and extradition dispute regarding allegations of child sex abuse at a Jewish religious school in Melbourne, Australia. A former principal, Malka Leifer, faced trial on 70 sex offence charges laid by Victoria Police, with accusations from at least eight alleged victims. Leifer, a dual Israeli-Australian citizen, fled under suspicious circumstances shortly before a warrant could be issued, and remained in Israel from 2008 until January 2021, under varying levels of police and court supervision, pending the resolution of her extradition case. Leifer's trial did not address other alleged sex crimes in Israel and the West Bank because they did not occur in Australia.
