Following the end of World War I, the Australian Government believed that an immediate evaluation of the RAN was necessary. Australia had based its naval policy on the Henderson "Recommendations" of 1911, developed by Sir Reginald Henderson. The government sent an invitation to Admiral John Jellicoe, he arrived in Australia in May 1919. Jellicoe remained in Australia for three months, before returning to England via New Zealand and Canada. Jellicoe submitted his findings in August 1919, titled the "Report on the Naval Mission to the Commonwealth". The report outlined several policies designed to strengthen British naval strength in the Pacific Ocean. The report heavily stressed a close relationship between the RAN and the Royal Navy. This would be achieved by strict adherence to the procedures and administration methods of the Royal Navy. The report also suggested constant officer exchange between the two forces. Jellicoe also called for the creation of a large Far East Imperial Fleet, which would be based in Singapore and include capital ships and aircraft carriers. The creation cost for this fleet was to be divided between Great Britain, Australia and New Zealand: contributing 75%, 20%, and 5% respectively. The suggested makeup of the RAN would include; one aircraft carrier, two battlecruisers, eight light cruisers, one flotilla leader, twelve destroyers, a destroyer depot ship, eight submarines, one submarine depot ship, and a small number of additional auxiliary ships. The annual cost and depreciation of the fleet was estimated to be £4,024,600. Except for implementing closer tier with the Royal Navy, none of Jellicoe's major recommendations were carried out.
