Cadet Uniform Buttons
Church of England Grammar School Cadets
The Anglican Church Grammar School (known as the Church of England Grammar School until 1984), was founded in 1912 as St Magnus Hall in Toowong. It relocated to East Brisbane in 1918. The crossed axes on the button symbolise Viking courage, and relate to the school’s patron saint, St Magnis, who was a Norseman.
The cadets corps of the school formed as part of D Company, 5th Battalion Australian Military Forces in 1919. After the suspension of compulsory cadet training by the Government in 1929 the school decided to continue none-the-less, its cadets becoming the Church of England Grammar School Cadet Corps.
Many former cadets enlisted during both World Wars. In 1948 it was claimed to be the largest cadet corps in Australia.
