HMAS Terka (FY.98) was an auxiliary minesweeper operated by the Royal Australian Navy (RAN) during World War II. The ship was launched as Sir Dudley de Chair in 1925, and operated by the Adelaide Steamship Company until she was requisitioned by the RAN in December 1940. She sank while at her moorings at Madang, New Guinea on 26 March 1945 and was abandoned.
She was bought in 1928 by the Adelaide Steamship Company and renamed Terka. She was requisitioned by the RAN in December 1940 as part of Minesweeping Group 70 based at Darwin, Northern Territory. She was converted into a water carrier and moved forward to New Guniea to support the efforts during World War II. While moored at Madang, she sank on 26 March 1945 and was abandoned.
During May-June 1971, the wreck of HMAS Terka, in Binnen Harbour, Madang was blasted by Clearance Diving Team One (RAN), to allow safe navigation of the harbour channel.
