[1][4] The locality consists of land bounded to the east by the Adelaide River and whose western boundary lies the immediate west of the Stuart Highway which passes through the locality in a north–south alignment.

[8][1][3] The 2016 Australian census which was conducted in August 2016 reports that Coomalie Creek had 20 people living within its boundaries.

[2] Coomalie Creek is located within the federal division of Lingiari, the territory electoral division of Daly and within the local government area of the Coomalie Shire.

[6][5][9] During World War II, Coomalie Creek Airfield was constructed by the Royal Australian Air Force in the locality, which was bombed by Japanese forces on several occasions.

Although it is on private land, the airfield has been partially restored and along with an anti-aircraft defence battery nearby, are some of the most intact examples of wartime infrastructure in the Northern Territory.
