The Island is 125km long and over 160,000 hectares in area. It was
formed during the ice age when the prevailing winds transported the vast
quantities of sand from New South Wales and deposited it along the coast
of Queensland forming the island as we know it today.
In this fragile eco system the rainforest consists of huge satinay and
brush box, kauri pines, piccabeen palms and the rare angiopteris fern
which is one of the largest ferns in the world. All this growing in pure
sand ! There are some wonderful walking tracks through these areas to
enable visitors to appreciate the unique beauty of the island.
There are a number of lakes on the island each with their own
individual character - from lakes stained red with tannin to others with
pure white sand and crystal clear water. Swimming in these lakes is
memorable experience.
Fraser is also home to over 200 species of birds along with a variety
of mammals, wallabies, snakes, possums, turtles and flying foxes.
Now listed as a World Heritage site, Fraser joins the ranks of the
Great Barrier Reef, Uluru and Kakadu National Parks as being of universal
significance as the largest coastal dune system and sand island in the
world and for its special environments. As a precious part of Queensland's
natural and cultural heritage, it is protected for all to appreciate,
enjoy and respect.
LAKES
It would be hard to imagine
lakes clearer than those on Fraser Island. The water is so pure that the
40 or so lakes support relatively little life. There are three types of
lakes on Fraser, window, barrage and perched lakes. Window lakes occur
when the ground drops below the water table. The fine white sandy base
acts as filters, giving the water its clarity. There are several window
lakes including Yankee Jack, Ocean lake and Lake Wabby. Lake Wabby is also
termed a barrage lake, which is formed by the damming action of a sandblow
blocking the waters on a natural spring. Wabby is relatively close to the
ocean side of the island and unlike the other lakes it supports several
varieties of fish. It is also a good example of the sandblow phenomena,
gradually encroaching on the deep green waters of Wabby as the sandblow
makes its gradual progress westward across the island.
Swimmers in the lake should not run and dive off the sandblow - the
water is very shallow close to the edge of the lake. Perched lakes occur
above the water table. Saucer-shaped depressions with a hard, impervious
base of organic matter and sand, form a catchment for the rain eventually
creating the lake. The peat-like base generally stains the water the
colour of tea. In the northern half of the island, Lake Bowarrady is the
highest of the perched lakes being some 120 metres above sea level. In the
southern part of the island there is Lake Birrabeen and the popular Lake
McKenzie. Lake Boomajin approximately 190 hectares in area is the world's
largest perched dune lake.
