Kalkaringi and Dagaragu communities (previously Wave Hill and Wattie Creek respectively) are located approximately five hundred and fifty kilometres south of Darwin. They are functionally one large community with a single combined council. At the time of the visit the combined population was about two hundred and fifty, mostly Aboriginal.
Two officers from the Medical Entomology Section of the Northern Territory Department of Health visited the three communities in early March 1981 to conduct both an Aedes aegypti survey and to assess the likelihood of exposure of community members to mosquitoes capable of being vectors of human disease.
