HMAS Mary Cam was an auxiliary minesweeper operated by the Royal Australian Navy during World War II. Originally launched in 1918 as Joule by Ritchie, Graham & Milne in Whiteinch, Glasgow, she was later acquired by Australian interests and renamed Mary Cam. The vessel was purchased by Cam & Sons Pty Ltd and sailed to Sydney in 1928, a voyage that took 69 days from Hull. After arriving in Australia, she operated in Australian waters as a commercial trawler. In 1939, the ship was requisitioned by the Royal Australian Navy on 5 October to serve as an auxiliary minesweeper during the wartime period. This marked her transition from civilian to military service, where she contributed to naval mine-clearing operations. After the conclusion of World War II, she was returned to her civilian owners and resumed her role as a trawler. Throughout her service, Mary Cam was involved in notable incidents, including an accidental grounding on Iphill Shoal in the Torres Straits, from which she was later refloated. A significant event occurred on 20 January 1948, when she collided with the liner Wahine, resulting in a buckled bow. Despite her active service life, she remained a relatively modest vessel, with her primary significance lying in her wartime auxiliary role and her long operational history. The vessel was eventually scrapped in 1957, marking the end of her maritime career. Her history reflects the versatile use of early 20th-century ships in both commercial and military roles, highlighting her contribution to Australian maritime operations during a critical period.
