The lake, with its surrounding mudflats and grasslands, has been identified by BirdLife International as an Important Bird Area (IBA) because it supports about 150,000 waterbirds with twelve species being represented in large enough numbers to be considered internationally significant. The mud flats and grasslands are the natural habitat of eight wader species also represented in internationally significant numbers, along with a healthy population of Australian bustards which are considered a "near threatened" species. Birds for which the lake has global importance include magpie geese, wandering whistling-ducks, green pygmy-geese, Pacific black ducks, hardheads, black-necked storks, white-headed stilts, red-capped plovers, Oriental plovers, black-fronted dotterels, long-toed stints and sharp-tailed sandpipers.
