Statement of Significance

Cockburn Sound Anti-Submarine Boom is rare nationally as a remnant anti-submarine defence system, and rare in Western Australia as a World War II related site.
Cockburn Sound Anti-Submarine Boom is tangible evidence of Australia’s World War II home front defence endeavours, and demonstrates the real fear of invasion.

Physical Description

Cockburn Sound Anti-Submarine Boom comprises three standing timber pylons extending above the water line, together with one collapsed pylon, several submerged beams and a section of exposed submarine netting on the seabed, in an open ocean setting.

History

These piles were once part of a World War II anti-submarine boom net pylon. Pylons were placed every 100m across the Parmelia Bank from Second Head, Garden Island to Woodman Point to protect Cockburn Sound from enemy submarine, midget submarine and human torpedo attack.
The net was constructed from 1942 and took two years to construct. The remnant structure was constructed in 1944 and is the last standing pylon of the boom net.
