The partnership between the AKF and the Ray Group has resulted in Koala Beach, a residential estate that is koala-friendly and proof that development and wildlife protection are not necessarily incompatible. The AKF is the world's largest funding body of koala research. Research findings include the contribution made by koalas to Australia's tourism industry and viability studies on koala populations in various bioregions. More than 40,000 km² of land has been mapped for the Koala Habitat Atlas. Unlike other mapping projects, the Atlas does not merely pinpoint the location of
