Join Colin Randall, a mining engineer and a volunteer for the Naval Historical Society of Australia, for an informed discussion on Garden Island Tunnel Complex, built during World War II.
The Garden Island Tunnel Complex is unique. This complex of tunnels and chambers provide evidence of the desperate days of World War II.Just four days after the Japanese attack on Pearl Harbour in December 1941, tunnelling commenced on the complex to provide Air Raid Protection requirements for the skilled workers on the Garden Island Naval Base. Designed initially to protect 1400 men standing up, it was expanded to accommodate 2500 men.The subsequent surrender of Singapore, the bombing of Darwin, the attack on Sydney by Japanese midget submarines and ultimately the shelling of Sydney on 8th June 1942 created imperatives that drove the excavation of the six interconnected tunnels and multiple chambers.
Colin Randall is a semi-retired mining engineer with 50 years of experience in underground and open cut mining. Since October 2018, as a volunteer in The Naval Historical Society of Australia, he has researched theGarden Island tunnel complex. As a teenager he lived on Garden island and was well acquainted with the tunnels. His first entry into a tunnel was in 1955 on the Snowy Scheme when he lived at Island Bend.
