It consists of land bounded in part by the Daly River and the Timor Sea in the north and north-west respectively, in part by the Fitzmaurice River in the south, and in part again by the Daly River in the east.[4]
Nemarluk is named in commemoration of Nemarluk (circa 1911 -1940), an aboriginal man notable as an “Indigenous resistance fighter”, a murderer and as a prisoner.[9] The locality's boundaries and name were gazetted on 4 April 2007.[1]
The 2016 Australian census which was conducted in August 2016 reports that Nemarluk had 131 people living within its boundaries.[2]
