Anbangbang Billabong, Kakadu National Park, NT, Australia. od Geoff Whalan

Anbangbang Billabong lies in the shadow of Nourlangie Rock within Kakadu National Park and is a good place to view a wide range of wildlife. Large numbers of water fowl and wading birds inhabit the billabong and many wallabies can be found grazing around the water’s edge. There is a walking trail around the circumference of Anbangbang billabong with many picnic areas. The Anbangbang Billabong is overlooked by the Nawurlandja and Nourlangie plateaus. In the wet season, it is fed by runoff from these plateaus, as well as overflow from Nourlangie Creek, however during the dry season it is cut off. Like much of Kakadu, Anbangbang Billabong is home to a particularly large variety of bird life. The fluctuating water levels draw waterfowl such as Magpie Geese, Pelicans, Darters, Spoonbills and Brolga. Other fauna known to frequent the billabong include Wallabies, File Snakes, Long-necked Turtles, Dingoes and Goannas. Mangroves lining the billabong support populations of Freshwater mussel. Adjacent woodlands play host to a different ecosystem again. The nearby Nawurlandja plateau supports local populations of Short-eared rock-wallaby and Chestnut-quilled rock pigeon, among other species. The swelling billabong promotes seasonal growth of Sedges, Grasses and Water Lilies, and Freshwater mangrove line the water's edge. Swamp areas support many types of paperbark, in particular the Weeping paperbark, Silver-leaved paperbark and Broad-leaved paperbark. The woodlands surrounding the billabong are a lush habitat comprising an abundance of plant species. Darwin woollybutt and Darwin Stringybark dominate, with large populations of Fan palms, Kapok, Red Apples, Wattle and Pandanus. Like much of Kakadu, the Anbangbang Billabong region's climate is monsoonal. The region's aboriginal owners recognize six seasons, however these can be reduced to vastly differing dry and wet seasons where the billabong is respectively depleted and replenished.
