By early afternoon we had reached Cameron Corner, where the borders of Queensland, New South Wales and South Australia meet and where Mike decided to climb the concrete stump and sit his bum on three states. There we also checked out a tiny part of the longest fence in world, built initially in the late 1800s to stop the spread of rabbits. Well, we all know that didn’t work and the fence was left to deteriorate. Then, years later, when dingoes were moving from cattle country into New South Wales sheep farming land and helping themselves to yummy lamb and mutton, the fence was restored. The 5,600 kilometre rabbit-proof fence was repaired and raised to two metres, effectively keeping the dogs at bay. What a job it would be, trying to keep that fence in good condition.
