Orara was requisitioned in September 1939 and was commissioned on 9 October into the RAN as an auxiliary minesweeper with the pennant number J130. She served in the 20th Minesweeping Flotilla. She also served as a depot ship.
In 1946 Orara was returned to owners and laid up in Sydney. In 1947 she was sold to Chinese buyers who took her to Shanghai,[1] renamed her Pearl River and registered her in Canton. In 1949 she was renamed Hong Shan. In 1950 she was renamed Santos and registered in Panama City.[3]
On 19 June 1950 Santos was steaming from Shanghai to Qingdao when a mine sank her in the Yangtze River near Wusong, with the loss of a number of lives.[6]
