A former chairman of the Native English Speaking Teachers' Association has been accused of committing a child sex offence at a prestigious Australian boys' school. Damien Vance, 55, who served as Nesta's chairman from June 2005 to March last year, appeared before a court in Sydney on April 9 after being extradited from the state of Victoria the same day. Vance was charged with inciting an act of indecency upon a 14-year-old boy between February and October 1988 at Knox Grammar School in Wahroonga, near Sydney, where he was a teacher. He is the fourth teacher from the exclusive school to be charged with retrospective sex and indecent assault offences. According to The Sydney Morning Herald, Vance was granted bail on terms that included weekly reporting to a Melbourne police station, not approaching any international points of departure and not entering Taylors College in Melbourne. Vance is believed to have been employed under the government's NET scheme for seven years, working at several different schools. Asked for details of his employment history, a spokeswoman for the Education Bureau said: 'It would not be appropriate for the EdB to disclose any information of the person concerned without his consent.'
