In October 1984 he was sentenced in the Sydney District Court to an effective term of imprisonment for eight years, with a non-parole period of four years, for the kidnapping and what is described as the assault of a five-year-old girl. He had persuaded the girl to accompany him to some unoccupied premises at Parramatta, where he had anal intercourse with her. He was released on parole in December 1986 but his parole was revoked in the following month, following a report which expressed concern about what Gallop J described as his “inappropriate and potentially dangerous behaviour towards young girls”. It is not necessary for present purposes to recount that behaviour, which is summarised at p9 of his Honour’s judgment. He was released when his sentence expired, presumably by remission, in December 1989.
