5 Dollars - Charles III 1st Portrait - Quokka Joey

The quokka, endemic primarily to Rottnest Island off Western Australia, was famously misidentified as a large rat by Dutch navigator Willem de Vlamingh in 1696 — the island's name derives directly from that error, "Rottnest" being a corruption of the Dutch for "rat's nest." This coin is part of the Royal Australian Mint's ongoing native fauna program, which has issued collectible silver pieces tied to Australian wildlife for decades, now transitioning to Charles III's first portrait following the Queen's death in September 2022.
