Graduates from that period are expected to attend a Back to Tocal weekend in July and will also mark the start of a college alumni in the vein of the country’s revered universities.

An ex-students’ association has served the college well and will continue to during the coming months, but the principal Cameron Archer said it was a fitting development.

“It’s sort of a coming-of-age step and it formalises that [association function],” he said. “We’ll be developing an alumni of ex-students and supporters.”

Dr Archer revealed the plans and the logo at the annual foundation day on Friday.

The logo features the Tocal Chapel spire.

Tocal College education delivery manager Darren Bayley said the logo would be used on a range of products and services over the next eight or nine months to draw attention to the milestone.

“To celebrate this we need a visual lightning pole,” he said.

While the college officially celebrates its 50th anniversary on November 5 next year, the Back to Tocal weekend will serve as the major celebration for past students.

Two books will also celebrate the occasion.

Tocal Master Plan and Heritage Significance is an overview of the grounds’ management and heritage preservation measures.

Lost and Unseen Tocal will record many of the site’s important locations, many of which remain unknown to many of the staff members.

n The Tocal campus is one of the most important complexes of educational buildings erected during the 20th century and the facility has received the Australian Institute of Architects (NSW) Enduring Architectural Award.

The award was announced on Thursday night and a plaque will be attached to the buildings.

Sue Hunt will unveil the plaque as the granddaughter of Edward Alan Hunt, who helped establish the college, and niece of architect Philip Cox.
