Under the scheme, all medically fit males 14–18 years of age had to serve in cadets.
Boys who did not comply were charged and dealt with by the courts. Senior cadets aged between 16–18 years of age were attached to Militia Units (now known as Army Reserve Units), called Regimental Detachments, while students aged between 14–16 years of age remained as school cadets.
The first official unit in Australia was established on 29 March 1866 at St Mark's Collegiate School by Reverend Macarthur.
In June 1868, The King's School had closed and did not reopen until January 1869, when it was amalgamated with the St Mark's unit, the unit was renamed The King's School Cadets Corps.
Uniforms, transport, rations and personal equipment all had to be funded by the school, parents or community organisations such as the RSL.
As a result, most government school based cadet units closed between 19.
While cadets are encouraged to consider enlisting in the military, it is not required that they do so.More than 2000 cadets representing the units of 41 state schools, 11 independent or private schools and one catholic school were inspected by the Governor.In 1910, the universal training scheme was introduced.Between 19, School Based Units were attached to Citizen Military Forces units.The CMF is the precursor of the modern day Australian Army Reserve. By 1951, The Commonwealth Cadet Corps was renamed the Australian Cadet Corps (ACC) and on 2 June 1953, The Duke of Edinburgh became the Colonel-in-Chief of the ACC, as a part of the coronation of his wife, Queen Elizabeth II.In 1869, the Newington College Cadet Corps was formally incorporated by the Governor of New South Wales (Somerset Lowry-Corry, 4th Earl Belmore) and that unit is now believed to be the second oldest continually running corps in Australia, after The King's School Cadet Corps.With the establishment of many cadet units and corps at numerous boys schools throughout the Commonwealth, His Majesty King Edward VII established the Commonwealth Cadet Corps in Australia on 16 July 1906.An embryonic corps was founded by Newington College when a drill master was appointed to staff in 1865.Two years later, a sergeant-major was appointed and muskets and carbines were purchased and an armoury and gunpowder store were opened at Newington College.The Australian Army Cadets (AAC) is a youth organisation that is involved in training and adventurous activities in a military setting.The programme has more than 19,000 Army Cadets between the ages of 12½ and 19 based in 237 units around Australia.
