The Royal Australian Navy is the naval branch of the Australian Defence Force. Following the Federation of Australia in 1901, the ships and resources of the separate colonial navies were integrated into a national force: the Commonwealth Naval Forces. Originally intended for local defence, the navy was granted the title of ‘Royal Australian Navy' in 1911.

The Royal Australian Navy provides maritime forces that contribute to the Australian Defence Force's capacity to defend Australia, contribute to regional security, support global interests, shape the strategic environment and protect national interests.
