Troubridge Shoals wreckings and strandings
A thorough look at the cited source for the section entitled 'Troubridge Shoals', i.e. Noble, John, Hazards of the Sea, Angus and Robertson, 1970, in a nearly public library revealed that the statements made in the two (i.e. 'over 33 wrecks and groundings') and third sentences (i.e. 'In 1850, at least seven vessels ran aground') were not sourced from that book. The book which is about wrecking events off the coast of the Australian continent does not have a specific section or any mention about the hazard of the Troubridge Shoals, and there is only mention of the shoals and its immediate locality is about Clan Ranald off Troubridge Hill (about 12.6 km West-southwest of the shoals) and the prospect of a lighthouse in order to assist travel through Investigator Strait. Accordingly, a 'failed verification' tag has been placed after the third sentence. Regards Cowdy001 (talk) 22:36, 16 August 2014 (UTC)
 * That reference originally referred to a sentence about the 1909 wreck of the Clan Ranald (Noble, J. Hazards of the Sea pp.172–176) at the Troubridge Hill end of the shoals. Rightly or wrongly, that sentence was deleted as irrelevant, but the reference was allowed to remain. Doug butler (talk) 06:27, 18 August 2014 (UTC)
 * I've found an appropriate reference, and remmed out the offending ref. I thought it arguable that the reef on which the Marion and Clan Ranald foundered is part of Troubridge Shoals, but I leave that to the geographers. Doug butler (talk) 07:52, 18 August 2014 (UTC)
 * Hi Doug, I have copies of several charts that show the extent of the Troubridge Shoals as extending from Sultana Point to just east of Troubridge Island and show Marion Reef as being a satellite of the overall shoals structure on the basis of location and water depth. Therefore, the waters off Troubridge Hill are not part of the Troubridge Shoals.  Also, the loss of the Clan Ranald is reported as being due to problems other than running aground - refer Arnott, T., (1996), Investigator Strait Maritime Heritage Trail, Heritage Branch, Department for Environment, Heritage and Aboriginal Affairs. Adelaide (ISBN 0 7308 4720 9)OCLC:38821544. and Coroneos, Cosmos & McKinnon, Robert; (1997), Shipwrecks of the Investigator Strait and the Lower Yorke Peninsula, Department of Environment and Natural Resources, Adelaide, South Australia. (ISBN 0-9588496-3-3) OCLC:40044611.  I just looked at  "Shipping Intelligence.". South Australian Register (Adelaide, SA : 1839 - 1900) (Adelaide, SA: National Library of Australia). 11 May 1850. p.2. Retrieved 18 August 2014, and cannot find any mention of seven groundings during 1850; the article only mentions the grounding of one vessel - the Ueslandes.  As I am working on an article about the 'Shipwrecks of Troubridge Shoals', I have searcher Trove to find reports on about 31 wreckings and strandings that appear to occurred on the Shoals with about other five events that claimed to stuck on the Shoals but are definitely located somewhere else.  So far, the Ueslandes is the only stranding for 1850.  Regards Cowdy001 (talk) 08:39, 18 August 2014 (UTC)
 * Hi Doug, I just found the following in the reference you added, i.e. 'This being the seventh vessel (the Ueslandes)that has touched on this shoal during the last eight months (i.e. October 18489 to May 1850)'. This statement was located near the bottom of the section under the heading 'Miscellaneous Shipping'. I have updated the article and thank you for the finding the reference.  Regards Cowdy001 (talk) 08:47, 18 August 2014 (UTC)
 * Nice work. Thanks for putting it/me straight. Doug butler (talk) 12:51, 18 August 2014 (UTC)

Marion Reef, Troubridge Hill, Clan Ranald and Troubridge Shoals
I have tagged the following with 'disputed' tag for the reasons listed below:"The Marion Reef, at the base of Troubridge Hill, named for the SS Marion, which ran aground in 1851 as did many others, most notably the SS Clan Ranald in 1909,  was once considered part of Troubridge Shoals"

Regards Cowdy001 (talk) 06:14, 19 August 2014 (UTC)
 * Firstly, Marion Reef is not at the base of Troubridge Hill; it is located about 16 km to the east at a position nearly due south of Troubridge Island - Its position is shown on the following chart - Edithburgh Small Boat Chart (published 1991) - there is a copy in the State Library of South Australia.
 * Secondly, Clan Ranald do not run aground - it capsized and sunk about 1 km from Troubridge Hill.  The loss is discussed in the following link which opens a PDF published by the former Department of Environment & Natural Resources - http://www.environment.sa.gov.au/files/6b446c73-87a6-4850-9459-9e2900d013fc/clan_ranald.pdf.  The PDF has a map showing the wrecksite's location in respect to Edithburgh and Troubridge Island.
 * Thirdly, the extent of the Troubridge Shoals is shown on the above-mentioned chart. The waters around Troubridge Hill have never been part of the Troubridge Shoals - there is a map attributed to Thomas Lipson when can be viewed at South Australia - Gulf of St. Vincent Troubridge Shoals. [cartographic material].  As the chart is in the public domain, I will upload it to Wikimedia for use with the various articles associated with Troubridge Island et al.

Category:Important Bird Areas of South Australia
"Category:Important Bird Areas of South Australia" has been removed from this article and moved to a new page currently acting as a redirect & tagged as having possibilities of expanded into a new article (i.e. Troubridge Island Important Bird Area) for the following reasons. Firstly, the Troubridge Island article needs to have a broad scope in order to discuss all of the things associated with it being an island of which bird life is only one aspect. Therefore, it is not appropriate to place it in a very specific category such as 'Category:Important Bird Areas of South Australia'. Secondly, both Troubridge Island and Troubridge Island Important Bird Area both describe a physical space which is different, i.e. the island has an area of 2 ha while the IBA has an area of 8 ha. Thirdly, an article such as Troubridge Island Important Bird Area is a good venue to discuss the bird life of Troubridge Island and its adjoining water in more detail than is appropriate to discuss in Troubridge Island. Fourthly, placing the 'Category:Important Bird Areas of South Australia' on the Troubridge Island Important Bird Area will result in a listing at Category:Important Bird Areas of South Australia which will assist those readers searching via categories associated with Important Bird Areas.
