Site description
This IBA is an area of hills 45 km north of Katherine in the southern Top End of the Northern Territory. The IBA is defined as the area known to support a breeding population of Gouldian Finches, bounded by Nitmiluk National Park and the Arnhem Plateau in the east. It is a series of rolling hills of skeletal sandy loams overlaid by angular cobbles. Mean annual precipitation is about 1000 mm, falling mostly from December to March. The hills are drained by a network of ephemeral creeks, which retain water through the dry season in scattered small pools. The rocky wooded hills are dominated by smooth-barked gums with an understorey of annual and perennial native grasses. The key features supporting the Gouldian Finches are the lack of grazing and few extensive hot fires, which enables native grasses to seed, persistent waterholes and springs for drinking, hollow-bearing trees for nesting, and perennial grasses on adjacent lowlands for feeding in the wet season. The site has been used by Traditional Owners and more recently for gold mine exploration.

Key biodiversity
Small numbers of the near threatened Australasian Bittern and Partridge Pigeon and the northern subspecies of the Crested Shrike-tit have been recorded (Woinarski and Tidemann 1991; NRETA 2007). The restricted-range (endemic) Yellow-rumped Mannikin is occasionally encountered within the IBA (Atlas of Australian Birds database).
