When thousands of (non indigenous) Buffalo walked into the wetlands of Kakadu, they stirred up mud and the water started to look murky and yellow. Hence the name Yellow Water. Not to be confused with the Yellow River in China. Apart from the name, nothing is really yellow. Most of the Buffalo were killed off to protect the natural ecosystem. The Yellow Water region boasts an incredible flora and fauna and is an absolute highlight of the Kakadu NP! Don´t go to Kakadu without visiting this area!!
