Wartime History
After news of the attack on Pearl Harbor on December 7, 1941, the Australian Army at Rabaul positioned two anti-aircraft battery to the top of the ridge, and quartered troops at the observatory. They went into action against the first Japanese air raid against Rabaul on January 4, 1942.

After the Japanese occupied this area, and installed their own anti-aircraft guns. Also, dug tunnels along Observatory Road that turns off Tunnel Hill Road.

Today
The present day observatory was established in 1980 and continues to operate to this day.
