'''HMAS ''Terka'' (FY.98)''' was an auxiliary [[minesweeper]] operated by the [[Royal Australian Navy]] (RAN) during [[World War II]]. The ship was [[Ceremonial ship launching|launched]] as '''''Sir Dudley de Chair''''' in 1925 as one of the three ships used to supply the construction of the [[Sydney Harbour Bridge]], and from 1928 operated by the [[Adelaide Steamship Company]]  until she was requisitioned by the RAN in December 1940. She sank while at her moorings at [[Madang]], [[Territory of New Guinea|New Guinea]] on 26 March 1945 and was abandoned.
==Construction==
The ship was [[Ceremonial ship launching|launched]] in 1925 from the [[State Dockyard]], [[Newcastle, New South Wales]] as ''Sir Dudley de Chair''.<ref name=Plimsoll1>{{cite web |url=https://plimsoll.southampton.gov.uk/shipdata/pdfs/45/45a1020.pdf |title=Lloyds Register |work=Plimsoll ShipData |access-date=14 August 2010}}</ref>
==Operation history==
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 Guinea]] 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 (RAN)|Clearance Diving Team One]] (RAN), to allow safe navigation of the harbour channel.
Following an overhaul of the RAN [[battle honour]]s system, completed in March 2010, ''Terka''{{'}}s wartime service was retroactively recognised with the honour "Darwin 194243".<ref name=newhonours>{{cite news |url=http://www.navy.gov.au/Navy_Marks_109th_Birthday_With_Historic_Changes_To_Battle_Honours |title=Navy Marks 109th Birthday With Historic Changes To Battle Honours |date=1 March 2010 |archive-url=https://web.archive.org/web/20110613184920/http://www.navy.gov.au/Navy_Marks_109th_Birthday_With_Historic_Changes_To_Battle_Honours |archive-date=13 June 2011 |publisher=Royal Australian Navy |access-date=23 December 2012}}</ref><ref name=honourslist>{{cite web |url=http://www.navy.gov.au/w/images/Units_entitlement_list.pdf |title=Royal Australian Navy Ship/Unit Battle Honours |date=1 March 2010 |publisher=Royal Australian Navy |archive-url=https://web.archive.org/web/20110614064156/http://www.navy.gov.au/w/images/Units_entitlement_list.pdf |archive-date=14 June 2011 |access-date=23 December 2012}}</ref>
