Lake McKenzie on Fraser Island is probably the most well-known freshwater lake in Australia. Located 100 metres above the sea level, it is classified as a 'perched lake', which means that all of the crystal-clear water comes from the rain. High levels of acidity in the lake and the fact that all nutrients have been washed out of the shimmering white silica sand make the water unsuitable for nearly all forms of plant and fish life. It is likely the purest water you'll ever dip your toes in. The Aboriginal name for the lake is Boorangoora, which means 'waters of wisdom'. It was and still is known as a place for decision-making.
