In the 1930s, the Anangu Pitjantjatjara Yankunytjatjara (APY) lands were used to establish Aboriginal communities in Southern Australia. Unfortunately, this area has a limited amount of available water with a majority of the communities' water coming from boreholes in deep fractured rocks. Additionally, these communities supplement these wells with collecting rainfall, but the APY lands receive infrequent rains with high rainfall events making it difficult to rely on rainfall alone [1]. To helps sustain these communities, GeoScientist Without Borders used geophysical tooling to locate groundwater resources. The first phase of the project was to use a magnetotelluric (MT) techniques to see if it could identify and characterize fracture rock
