The Sydney Harbour Transport Act of 1951 established the Sydney Harbour Transport Board. The source records a takeover of Sydney Ferries Ltd. on 1 July 1951 and operation as Sydney Harbor Ferries Ltd., but also cites an account in which the latter company owned Port Jackson & Manly services, operated by that company until Brambles disposed of its ferry interests.
Accounts differ over the successive authorities and dates. Rosanoski records reorganisation as the Public Transport Commission in December 1974, while the Commission itself had been established in 1972 for rail and bus services. Transfer to the Urban Transit Authority is dated both 1 July 1980 and 1983. One account dates the State Transit Authority’s replacement of the Urban Transit Authority to 1989; Lloyd’s records the title State Transit – Sydney Ferries from 1995. Sydney Ferries became a separate state-owned corporation in July 2004.
