a music/visual art department. The 125th anniversary of Caulfield Grammar's founding was marked in 2006 and various events were held in commemoration. On 26 April 2006, the school community held a day of celebrations (ANZAC Day—a national public holiday—is held in Australia on 25 April, the actual anniversary of the founding). Staff and students at all five campuses of the school—with student groups visiting both the Nanjing and Yarra Junction campuses at the time—formed "125TH" at their respective campuses and an aerial photograph was taken. Other celebrations during the year included a 125th Anniversary Ball at Crown Casino for past and present staff and parents, as well as past students. The annual Founders' Day service at St Paul's Cathedral was attended by guest of honour, Governor of Victoria Dr. David de Kretser, a past parent of the school. The School Council commissioned author Helen Penrose to write a history of the school entitled Outside the Square, which was released in 2006. Caulfield Grammar School now has over 3,000 students throughout its three-day campuses. It is the only Melbourne-based school in the APS to provide boarding for both boys and girls, with nearly 100 boarding students from rural Australia, Melbourne and overseas. The school is a member of the Associated Public Schools of Victoria (APS), and is affiliated with the Headmasters' and Headmistresses' Conference, the Association of Heads of Independent Schools of Australia (AHISA), the Junior School Heads Association of Australia (JSHAA), the Australian Boarding Schools' Association, and the Association of Independent Schools of Victoria (AISV). Yarra Junction Campus In 1947, a country centre opened at Yarra Junction on land donated by the Cuming family. Cuming House was the first outdoor education campus for an Australian school, set in the Australian bush and close to the Yarra River. The Yarra Junction Campus today allows students to live in sustainable eco-cabins with rainwater tanks and solar power technology. The Earth Studies Centre, Wadambawilam (Aboriginal term for 'learning place'), operates on wind and solar power, and uses many environmentally sound practices to teach students about long-term environmental sustainability. Also on campus is a commercial dairy which produces over 1 million litres of milk annually. On United Nations World Environment Day 2001 the Yarra Junction Campus won an award for Best School Based Environment Project for its energy-saving eco-cabins project. Nanjing Campus The school opened a fifth campus in Nanjing, China in 1998, with
