Summary These intertidal mudflats have supported more than 1% of the world population of Grey-tailed Tattler, Eastern Curlew and Great Knot, as well as moderate numbers of the near threatened Asian Dowitcher. However, the area is poorly surveyed and the regularity of these numbers is unknown.
Site description This IBA comprises the intertidal mudflats around Port McArthur along the Gulf of Carpentaria coast from Mule Creek (east of Bing Bong homestead) eastwards to an unnamed tidal creek about 30 km east of Pelican Spit. It includes the immediately coastal saline wetlands but not the extensive inland wetlands, which were "not observed to have large numbers of shorebirds" (Chatto 2003). The intertidal mudflats are up to 5 km wide (widest near river mouths) and connect across the South-West Island of the Sir Edward Pellew group.
