Australia's Dog Fence

Do you know what is Australia's most dangerous animal? The dingo (a wild dog). So dangerous is it to livestock, that Australia built a fence around one quarter of the continent to keep them out! At 5600 km, it is the worlds's longest unbroken fence and is two and a half times the length of the Great Wall of China!

The fence was built in the early 1900s to keep wild dogs out of South-Eastern Australia, which has a lot of sheep. Cattle, which are less vulnerable to dogs, are reared mostly in the west.

If you think that's crazy, hear this: One of Australia's serving PMs, Harold Holt, died by drowning on a beach while swimming!

That continent never ceases to amaze me!
