The bunker walls were 1.5 metres thick and it was almost bomb proof. It had all the latest equipment of the time to allow it to run as a top secret defence base. It had its own code room, plotting rooms, two escape tunnels, radio transmitter room, kitchen, dining area, bathrooms and bedrooms. In the center of the bunker was a large operations room. This was a large room about two stories high. It was the control centre for all air force missions in the Pacific area. The room also had a big map of the South West Pacific theater of World War II. The bunker also had its own generator, air conditioning and switchboards which directed fifty telephone lines. The telephone lines went to various locations including radar stations and VAOC lookout posts which reported aircraft locations to the bunker. There are rumours of a tunnel running from the bunker to an unknown location.
