Peter J. Cornish was appointed Principal in 1981, and is credited with returning the school to financial security and academic respectability in the period 1981 to 2002. Cornish was formerly Deputy Headmaster of The Armidale School, and previously an English master at Shore (Sydney Church of England Grammar School), both Anglican boys' schools. He emphasised academic achievement, as well as developing numerous sport and co-curricular opportunities. Cornish cultivated an association with several neighbouring Anglican parishes, including the immediately adjacent mainstream Anglican parish of St Peter's, Cremorne, and indeed the school continues use of the parish church as the Secondary School chapel. On Foundation Day 2007, the Governor Phillip Building was renamed the Peter Cornish Building, in recognition and honour of his achievements and progressions in the school. The Boys 1st IV Rowing boat was also named in his honour at a ceremony on 16 March 2008.
