Tank Trap: In the early days of World War II invasion, of Australia, by Japan was an ever-present threat. In Northern New South Wales steps were taken to impede the advance of the Japanese army if the invasion reached this far south. East of Armidale, on the road to the coast a tank trap was constructed. A tunnel was dug under what is now a disused section of the road and filled with explosives. On the upper side of the road was a steep cliff whilst the lower side sloped away to a wetland. On the lower side a series of large, upright timber posts were placed in the ground from the road to the edge of the wetland. In the wetland two rows of concrete pyramids (see image) were placed in line with the timber posts.Environment
If an invasion force came this far then the road would be blown up and hopefully the posts and pyramids would slow up the tanks and other invading vehicles. Fortunately the Tank Trap was never used. Most of the timber posts have survived for the past fifty years although they have been rather scarred by a succession of bushfires. The concrete pyramids are in mint condition and are likely to remain so for at least the next fifty years. This historic site is now protected in Cathedral Rock National Park.
