The Aboriginal community of Galiwinku is situated on the west coast of the southern tip of Elcho Island approximately 525 kilometres east of Darwin. The Island itself is of considerable size ( approximately 300sq km ie 50km x 6km average width) and lies adjacent to the north coast of the Northern Territory about parallel to the Napier Peninsula. The community lies within the Northern Territory Department of Health East Arnhem Region and is directly accessible by air and sea.
Two Officers from the Medical Entomology Branch, Mr Geoff Davis, Medical Entomologist and Mr Andrew Masters, Technical Assistant visited the community during the period 16 to 19 April 1984 to conduct a vector mosquito survey.
