Admiralty
It evolved from *Admiralty Navy War Council, (1909–1912) which in turn became the Admiralty War Staff, (1912–1917) before finally becoming the Admiralty Naval Staff in 1917. It was the former senior command, operational planning, policy and strategy department within the British Admiralty. It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished, and the staff departments function continued within the Navy Department of the Ministry of Defence until 1971 when its functions became part of the new Naval Staff, Navy Department of the Ministry of Defence.
History of the Royal Australian Navy
In 1848, an Australian Division of the East Indies Station was established, and in 1859 the British Admiralty established an independent command, the Australia Station, under the command of a Commodore who was assigned as Commander-in-Chief, Australia Station. The Australian Squadron was created to which British naval ships serving on the Australia Station were assigned. The changes were partially in recognition of the fact that a large part of the East Indies Station had been detached to Australian waters, and also reflecting growing concern for the strategic situation in the western Pacific in general, and in Tahiti and New Zealand in particular. In 1884, the commander of the Australia Station was upgraded to the rank of rear admiral.
