Contemporary household water storage patterns recorded in 3 Brisbane suburbs over an 18 month period from 2008 to 2009 revealed that the drought led to significant changes in householders’ behaviours in regards to water storage and water usage. Generally, garden containers remained key habitats for Ae. notoscriptus, but water storage containers emerged as key habitats in some suburbs. This behaviour of intentionally filling or harvesting water provides suitable, year round, habitat for container breeding mosquitoes potentially increasing the receptivity of urban Brisbane to Dengue vectors. As a result of this work it was agreed that the survey be expanded to include 90 (of a total 158) Statistical Local Areas (SLA) in the Brisbane region. Utilising the QIMR Berghofer developed VEDS system, Brendan, along with Vector control officers form Brisbane City Council and Environmental Health Officers from Queensland Health have to date (June 2012) surveyed over 4000 houses and collected over 5000 larval mosquito samples from over 50,000 containers. This data will be vital in assessing the receptivity of urban Brisbane to dengue vectors Ae. aegypti and Ae. albopictus.
