The Rabbit Proof Fence continued

Until the 1920s there were very few rabbits west of the Number 2 Rabbit Proof Fence. Officers patrolled the fence line doing maintenance work using camels, horses and automobiles for transport. It was a solitary, but important job.
Western Australia experienced major problems with rabbits beyond the fence line from the 1920s through the 1930s and 1940s. The significance of the Rabbit Proof Fence was reduced in the 1950s following the nationwide introduction of myxymatosis as a method of controlling rabbit populations.
