Nganmarriyanga (formerly Palumpa) is an Aboriginal community in the Daly River region of the Northern Territory, Australia. Nganmarriyanga is also called Palumpa, the name of the local cattle station. With a population of 343, (in the 2011 Census) it is 131 km west of the Daly River crossing along the Port Keats Road. There is road access to Nganmarriyanga around eight months of the year, usually from May until December. During the wet season, the area is only accessible via plane because the roads are impassable due to regular flooding. The main language spoken in Nganmarriyanga is Murrinh-patha, with English as the second language. People at Palumpa like to hunt bullock, turtle, goose, goanna, cat-fish, kangaroo and fish.
