Shipping services on the Sydney-Victoria route were started by James Huddart who formed the Canadian-Australian Steamship Co. in 1893. This company was wound up in 1898 and others took over the services. The Canadian-Australasian Line Ltd was formed jointly by the Union Steam Ship Company of New Zealand and Canadian Pacific in 1931. The Union Steam Ship Co. remained as managers. Services ceased in 1941 and recommenced from 1948 until 1953 when the company was wound up.
