In general, the area of Australia suitable for the transmission of dengue is projected to increase , but estimates of local disease risk vary considerably according to climate change scenario and socioeconomic pathways . The spread of Wolbachia among Aedes mosquitoes in northern Australia has already reduced dengue transmission and may decrease the influence of climate in the future . In New Zealand, the risk of dengue remains low for the remainder of this century . Higher temperatures and more intense rainfall may also increase pollen production and the risk of allergic illness throughout the region .
