The facility is located about 120 kilometres (75 mi) south of the town of Katherine and RAAF Base Tindal, Australia's largest airbase.

Its large area—2,110 square kilometres (810 sq mi)[2]—and 60,000 feet (18,000 m) of vertical airspace clearance allow virtually unrestricted freedom of tactical testing and training using any conventional weapons.

In addition to its large mass inert weapon range, Delamere also has two practice ranges for smaller weapons testing, a simulated airfield complex, and a simulated township constructed from shipping containers named "Tac Town".

[3] Delamere is 100 kilometres (62 mi) east of the larger Bradshaw Field Training Area which has an area of 8,700 square kilometres (3,400 sq mi), and the Department of Defence has considered acquiring land between the two facilities to merge them.

Delamere is electronically linked with Bradshaw Field and Mount Bundey Training Area to form the North Australian Range Complex.
