were replaced in 1970 by an elected School Committee to represent the student body, the publication of a student newsletter Demos—containing editorials on aspects of the school—was allowed, religious education classes were made voluntary for senior year levels, the position of school chaplain was abolished, and Caulfield Grammar was the only APS school to allow its students to participate in moratorium marches protesting the Vietnam War on 8 May 1970. The school's centenary year, 1981, marked the appearance of the first girls at Caulfield Grammar, as a second senior school campus opened at Wheelers Hill on 26 April. Caulfield Grammar had purchased the land for a future project in 1969, and a new campus was established to celebrate the centenary. Wheelers Hill began as a coeducational school for all year levels. In 1993, the other campuses opened to girls, making Caulfield Grammar fully co-educational. The school established a computer network in 1997 with all students and staff having individual log in details, email accounts, and file space. The school provides an online login system or Intranet for students and staff that is accessed via existing entry passwords and usernames. This capability is referred to as the School's sixth or "virtual" campus, and enables access to email and files from the school network over the Internet. In 2019, the school released an app called CaulfieldLife, allowing students and staff to access a range of information from their personal devices. The school's historic War Memorial Hall, opened by Sir Dallas Brooks, the Governor of Victoria, on 27 April 1958, had cost some £50,000 (approx. $12 million in 2016) to construct on the Caulfield Grammar Campus. In the early morning of 7 November 2000, the "Cup Day" public holiday, a fierce fire broke out in the then-being-refurbished building (just two weeks away from completion); the roof collapsed, and the entire building was destroyed — only Alan Sumner's stained glass memorial windows escaped damage. The school then began to plan the construction of major halls at both the Caulfield Grammar and the Wheelers Hill campuses, naming the project "The Twin Halls". The Memorial Hall at Wheelers Hill was officially opened on 28 July 2005, and the "Cripps Centre", its counterpart on the Caulfield Grammar Campus opened on 25 October 2005. Each hall seats 650 people: the Wheelers Hill hall including a new chapel fitted with a multimedia centre, and the Caulfield Grammar hall including
