Service
Orontes began her maiden voyage on 24 October 1902, taking mail and passengers from London via the Suez Canal and Melbourne to Sydney. This was her regular route.
By 1913 Orontes was equipped for wireless telegraphy, operating on the 300 and 600 metre wavelengths. Her call sign was MOZ. In 1914, between the 11th and the 21st of July, two Polish passengers, Mr. B. Malinowski, anthropologist, and Mr. St. I. Witkiewicz, artist, travel in RMS Orontes from Colombo, Ceylon, to Fremantle, Australia. Mr. Witkiewicz takes part in a scientific expedition to New Guinea. Mr. Witkiewicz soon abandoned the expedition and returned to Europe, to sign up for military service during the First World War. After the First World War began, Orontes remained in service on her regular route until October 1916, when the Admiralty requisitioned her. She was converted into the Royal Navy troop ship HMAT Orontes. HMAT stands for "His Majesty's Australian Transport". She made two more voyages from Britain to Australia, before spending some time on the Africa run.[4] In 1917, the Admiralty released her to her owners, as her refrigerated hold made her more useful for taking dairy products and meat from Australia to Britain.[5]
In 1919 Orontes resumed her Australia service with calls at Gibraltar, Toulon, Port Said, Colombo, Fremantle, Adelaide, Melbourne, Sydney and an extension to Brisbane.[6]
In 1921 Orontes was laid up in the Thames. In 1922 British World Trade Expeditions Ltd bought her with the intent of converting her to an exhibition vessel. She was to be renamed British Trade, but it is not clear whether her change of name was ever registered.[7] Orient Line repossessed the ship.[2]
