Blinky Bill is an anthropomorphic koala and children's fictional character created by author and illustrator Dorothy Wall. The character of Blinky first appeared in Brooke Nicholls' 1933 book, Jacko – the Broadcasting Kookaburra, which was illustrated by Wall. Wall then featured Blinky Bill in a series of her own books, including Blinky Bill: The Quaint Little Australian, Blinky Bill Grows Up, and Blinky Bill and Nutsy. The books are considered quintessential Australian children's classics, and have never been out of print in Australia.
