Eli Creek is in an ancient rainforest valley on the eastern side of Fraser island, in Central Queensland. It is fed by a natural aquifer (water table) that is exposed to the outside elements several kilometres inland. Eli Creek produces up to 80 million litres of water per day (an amazing 4 million litres of water flows through it and out to the ocean EVERY HOUR) Another amazing fact is that it takes up to 100 years for water to be filtered through sand. By the time the water reaches the mouth of Eli Creek, it may have travelled from one of the sand dunes on the island which are 200 metres above sea level. It is theorised that some of this water may not have been exposed to the outside environment for hundreds of years.
Finally I must add that this is one of the most magical places we visited during several trips to Queensland in the 1980’s. I actually swam the length of this creek which gave me an appetite for the great BBQ lunch we enjoyed on the banks.
