The rationale behind the policy included the possibility of savings in fuel and maintenance that would result from Indian Ocean deployments beginning their journey from Western Australia rather than New South Wales. The report also classed the Indian Ocean as an area where contingencies might arise. The new facilities would increase Australia's worth to the United States, particularly to do with maintenance of submarines. Expansion at Jervis Bay would allow intensified east coast visits by the United States Pacific Fleet, and its nuclear warship visits would not run into as much opposition as they do in Sydney and Melbourne.
