There are three fences in Western Australia: the original No. 1 Fence crosses the state from north to south, No. 2 Fence is smaller and further west, and No. 3 Fence is smaller still and runs east–west. The fences took six years to build. When completed in 1907, the rabbit-proof fence (including all three fences) stretched 2,023 miles (3,256 km). The cost to build the fences at the time was about £167 per mile ($250/km).
No. 2 Fence intersects with most of the Whealtbelt railway lines. The Number 2 Rabbit Proof Fence was built in 1905 in order to stem the rabbits advance after they were found west of fence No.1. Stretching 1166 kilometres from Point Ann on the south coast through Cunderdin, 150 kilometres east of Perth, the new fence joined the original fence line at Gum Creek in the Murchison area.
The cache is located on Rabbit Proof Fence Road, where parts of the original fence still stand between Dowerin and Wyalkatchem.
