HMAT Warilda (His Majesty's Australian Transport) was a 7713 ton vessel, built by William Beardmore and Company in Glasgow as the SS Warilda for the Adelaide Steamship Company. She was designed for the East-West Australian coastal service, but following the start of the First World War, she was converted into a troopship and later, in 1916, she was converted into a hospital ship.
Time as a troopship
- 8 October 1915: 10th Reinforcements, 1st Infantry Battalion embarked from Sydney heading to Egypt.
- 8 November 1915: 10th Reinforcements, 1st Brigade of the AIF, embarked from Liverpool, NSW, Australia. The ship arrived at Fremantle, Western Australia on 15 October 1915, and reached Suez on 5 November, a Friday, where the troops were disembarked.
- 25 May 1916: Tunneling Companies, 2 Reinforcements embarked Melbourne.
- 1 June 1916: Tunneling Company 6, 3rd Tunneling Company embarked from Fremantle, Western Australia 1 June 1916. Disembarked Plymouth, England, 18 July 1916.
On 3 August 1918, she was transporting wounded soldiers from Le Havre, France to Southampton when she was torpedoed by the German submarine UC-49. This was despite being marked clearly with the Red Cross; as with a number of other hospital ships torpedoed during the war, Germany claimed the ships were also carrying arms.
The ship sank in about two hours, and of the 801 persons on board, exactly 123 people were sent to their deaths when the Warilda sank to the sea floor. Amongst the survivors was her commander, Captain Sim, who was later awarded the OBE by King George V. Her wreck lies in the English Channel
