It might have been rabbit proof once, but not today.
Times have change from when rabbits around Australia were an uncontrollable pest and fences like this one along with 1080 poison, warren ripping and even explosives were desperate measures.
Rabbits are still around but the Calici-vitrus, introduced in Australia in the 1990s has had some success but its potency is waning.
Interestingly, the lines that can be seen in the middle ground of this photograph are the familiar sedimentary lines so often visible along the tops of the hills and mountains of the Flinders Ranges.
I guess that once they would have been quite pronounced, but time and weather have worn them almost away.
The fence and the peaks are on Angorichina station near the town of Blinman.
