In the following May, P. A. V. Roff, formerly Headmaster of Scotch College, Adelaide, was installed as the seventh principal of the college. Roff's tenure, though a brief seven years, was characterised by an expanding voice for staff in the day-to-day management of the school, the establishment of a Foundation Office at the School under the direction of a Development Officer and the widening of the House System to provide greater depth in pastoral care. His last few years saw the school in dispute over ownership and, for the principal and his school community, it was a time of stress. In 1980 the decision was made to incorporate the school and a new Council was appointed, with representatives from the Presbyterian Church, the Old Scotch Collegians' Association and the community at large.
