Vice admiral (Australia) in the context of "Royal Australian Navy"

The Royal Australian Navy (RAN) is the naval branch of the Australian Defence Force (ADF). The professional head of the RAN is Chief of Navy (CN) Vice Admiral Mark Hammond. The Chief of Navy is also jointly responsible to the Minister for Defence (MINDEF) and the Chief of the Defence Force (CDF). The Department of Defence, which is a part of the Australian Public Service, supports the ADF, and ergo, the Royal Australian Navy.

The navy was formed in 1901 as the Commonwealth Naval Forces (CNF) through the amalgamation of the colonial navies of Australia following the federation of Australia. Although it was originally intended for local defence, it became increasingly responsible for regional defence as the British Empire started to diminish its influence in the South Pacific.
