Fraser Island sits on top of a huge underground reservoir of fresh water. Much of the 1800 millimetres of rain the Island receives each year, filters through the sand until it is held by the rock base some 30 metres below sea level. As a result, there is an abundance of natural springs feeding freshwater streams that ceaselessly pour into the Pacific Ocean to the east and Hervey Bay to the west.In one 30 kilometre section of the famous 75 mile eastern surf beach 200 creeks run into the Pacific Ocean; some large, some appearing as just wet sand from fore dune to surf. The largest and most attractive on the eastern shore is Eli Creek, which winds from many kilometres inland to carve its bed through the beach and pour 8 million litres of water a day into the Pacific Ocean.
Eli Creek is the largest freshwater creek on the eastern coast of the island. It is an area of exceptional and pristine beauty. This creak is very popular in the late afternoon on hot days, with kids particularly loving this destination. There are a number of wooden walkways and a short, circular route runs up one side of the creek and down the other. It is possible to swim in the lower reaches of the creek.
