Adelaide Steamship Company

 This Company, floated in 1875, was an outgrowth of the need to service South Australia's pastoral and agricultural interests from as early as the mid-1850s. Embracing some earlier-formed companies, it coalesced in 1912 into the Coast Steamships Company, this in turn being taken over by the Adelaide Company in 1915. Its ships contributed to the national effort during the Great War, with Grantala (3655 gt) at risk while supporting as a hospital ship August-December 1914 the Expeditionary Force landing at Rabaul, and Willochra requisitioned in November 1914, Wandilla in May and Warilda in August for trooping, the last two (each about 7000 gt) being converted to hospital ships in August 1916, serving thus to 1918. Warilda was sunk by a submarine on 2 August 1918.

At the start of the Second World War the company owned twenty-nine ships:
