The Yirrganydji (Irrukandji) people are an indigenous Australian people of Queensland who trace their descent from the Irukandji and, as such, are the original custodians of a narrow coastal strip within Djabugay country that runs northwards from Cairns, Queensland to Port Douglas. Their traditional lifestyle was that of fishers along this coastal strip and around the river mouths, islands and seas between the Cairns Trinity Inlet and Port Douglas
