Cook, Victoria, was the preferred location. The Australian Flying Corps (AFC) was subsequently formed as a Militia unit, with staff and students to be selected from the Citizen Forces, and the first flights by CFS aircraft took place in March 1914. World War I and the Inter-war years Soon after the outbreak of World War I in August 1914, the AFC sent aircraft to assist the Australian Naval and Military Expeditionary Force in capturing German colonies in what is now north-west New Guinea. These colonies surrendered quickly however, before the planes were even unpacked. The first operational flights did not occur until 27 May 1915, when the Mesopotamian Half Flight was called upon to assist the Indian Army in protecting British oil interests in what is now Iraq. The corps later saw action in Egypt, Palestine and on the Western Front throughout the remainder of World War I. By the end of the war, four squadrons – Nos. 1, 2, 3 and 4 – had seen active service; another four squadrons – Nos. 5, 6, 7, and 8 – had also been raised to provide training in the United Kingdom. The AFC was disbanded along with the rest of the Australian Imperial Force in 1919, following the end of hostilities. Although the Central Flying School continued to operate at Point Cook, military flying virtually ceased until 1920, when the Australian Air Corps was formed. The following year, this was separated from the Army on 31 March 1921, when the Australian Air Force was formed as an independent service; in May that year King George V gave his assent for the service to use the prefix "Royal" and this came into effect on 13 August 1921. Upon formation, the RAAF had more aircraft than personnel, with 21 officers and 128 other ranks, and just 170 aircraft. Initially, it had been planned to expand the force to 1,500 personnel – three-quarters permanent staff and one quarter reserves – who would serve in six squadrons: two of fighter aircraft, two of reconnaissance aircraft, and two squadrons of seaplanes. These plans were scuttled a year after formation due to budget constraints and until 1924, the service's strength remained steady at just 50 officers and 300 other ranks; of the six planned squadrons, only five had been raised, albeit cadre strength, and these were subsequently merged into a single mixed squadron until 1925.
