1 Dollar - Charles III 1st Portrait - Adorable Quokka Joey

The quokka — native almost exclusively to Rottnest Island off the Western Australian coast — was named by Dutch explorer Willem de Vlamingh in 1696, who mistook the animals for large rats and called the island "Rottenest" accordingly. This coin is part of the RAM's ongoing native fauna series, which has leaned increasingly into younger animals as a circulation-boost strategy since the mid-2010s.
