(ABC News: Jasmine Hines)Burying wrecks in sand, road crash barriersWhile Queensland has yet to employ any of these tactics to save underwater wrecks, it has been done elsewhere in Australia.Ms Jordan said more than a decade ago there was some experimental work done preserving historic wrecks in Victoria and Western Australia.In Western Australia, a series of road crash barriers were put around the James Matthews shipwreck.Road crash barriers were used to surround the James Matthews wreck. (Supplied: WA Museum)It was then covered in sand to create an anaerobic environment, meaning oxygen could not impact the wreck."Because it's such a unique example of a type of ship, it was decided that the need to preserve it was of greater importance for our understanding of that type of history than people viewing it," Ms Jordan said."As researchers and archaeologists, you do have to sometimes weigh that up."The James Matthews under sand following its reburial in 2013.
