The Australian fifty dollar note is an Australian banknote with a face value of fifty Australian dollars ($50, AUD50). It is currently a polymer banknote, featuring portraits of David Unaipon and Edith Cowan.
On 4 October 1995 a new set of polymer banknotes were released. Designed by Brian Sadgrove, the new fifty dollar note features a portrait of Indigenous Australian author and inventor David Unaipon on the front, along with drawings from one of his inventions, and an extract from the original manuscript of his Legendary Tales of the Australian Aborigines. On the back is a portrait of Edith Cowan, first female member of any Australian parliament, along with a picture of Western Australia's original Parliament House, and an illustration of a foster mother and children.
