Wooden stumps were installed in locations along the “Brisbane Line” to force tanks to rise up, exposing the belly for attack with explosives.
The rugged terrain would have forced enemy vehicles to have to use roads, which would have been destroyed. Tank traps and boulders were part of the defensive line.
A brown sign is fixed to the cement wall opposite the tank traps with the following:
Tank traps which were erected during the war (these are to the left of the cement wall, in the form of posts standing upright). This is the area of the Brisbane Line which was to be the second line of defence if the northern part of Australia fell into enemy hands. During the war up to 10,000 troops were camped in the Tenterfield district.
A walking track connects the WW2 tank traps with Thunderbolt’s Hideout 
, located about 1km towards Tenterfield.
