The Anson Bay, Daly and Reynolds River Floodplains comprise some 2,656 square kilometres (1,025 sq mi) of seasonally inundated floodplains around Anson Bay, and the lower reaches of the Daly, Reynolds and Docherty Rivers entering the bay, on the west coast of the Top End of the Northern Territory of Australia. Anson's Bay lies about 120 kilometres (75 mi) south-west of Darwin, on the eastern side of the Joseph Bonaparte Gulf, opening on to the Timor Sea. The site is important for large numbers, and a wide variety, of waterbirds.
