Within fifteen kilometres of our home are tunnels constructed into the natural cliff face, the headland on which Darwin, the capital of the Northern Territory, stands.

During World War Two, the tunnels housed surveillance equipment and cannons with ship-destroying capacity.

These runnels have become a major tourist attraction. Guided tours and commentary are offered.

I know this from what people have told me. These tunnels attract people from all over the world – but I have never visited.

We have lived in Darwin for 37 years.
