Predicted continued increases in arid conditions in Australia are expected to reduce the recharge rate of finite groundwater supplies . For remote communities reliant on groundwater for drinking supplies, this water insecurity creates vulnerabilities from over-extraction and lack of access . This groundwater can also have microbial contamination from sewage and chemicals supporting bacterial growth, such as high iron levels supporting the growth of Burkholderia pseudomallei that causes melioidosis in humans and animals . In the Torres Strait, increasing reliance on desalination for drinking water raises costs for fuel and its associated transport
