Formation In late 1920, the Navy Board proposed the creation of an Royal Australian Naval Volunteer Reserve scheme, with approaches made to yachting and rowing clubs, starting in New South Wales, South Australia, Victoria, and Tasmania. Men who were undergoing or liable to compulsory training under the Defence Act (Cwlth) were ineligible for enrolment. For the volunteers, a period of five years of service was proposed with parading twice a month, training occur outside of business hours, entry as an able seaman rating, and officer appointments not based on social or other positions. Requirements later included fourteen days training every alternate year, and 'seven days out of this period should be spent afloat'. By 1925, following mufti attire on parades, the uniform was determined to be the same as the regular forces, with 'RANVR' replacing 'RANR' on the cap band, and the uniform to be supplied by the government instead of the individual as had been the case in the past. Members, unless former ratings of the Royal Navy or Royal Australian Navy, had to be more than 21 years-of-age.
