Fraser Island is the world’s largest sand island, a giant sandmass 123km long and up to 25km wide. It was World Heritage-listed in 1992 for its areas of exceptional natural beauty, for representing major stages of Earth’s history and for representing ongoing ecological and biological processes involved in the Island’s ecosystems evolution.
Over the past 2 million years, currents and waves have been sweeping sand which accumulated in dunes parallel to the coast. Strong onshore winds blow loose sand inland to form high parabolic dunes which spread inland, engulfing areas in their path.
Fraser has 43 large sandblows! They form when vegetation on dunes is broken by fire, wind, storms, walkers and/or vehicles. The now loose sand is blown by onshore winds until stopped by the nearby vegetation, eventually covering it. They engulf everything in their path at rates up to one metre each year! Eventually the vegetation recovers and recolonises behind the advancing sandblow.
Plants growing on sand draw mineral nourishment from 2 surprising sources : they strip the fine mineral coating from grains of sand (turning the grains white!) and also absorb minerals from rainfalls! Decaying plants return these minerals to the sand so as successive dune layers form, it becomes able to support taller, more complex forest. Fraser forests are of international scientific interest!
Three different types of freshwater dune lakes can be found on Fraser. Formed in sand, they have crystal clear or amber-stained waters (tannins from decomposing vegetation). They are low in nutrients and support limited aquatic life.
Perched lakes are the most common on the Island. They develop when an impermeable layer of organic debris forms in a sand depression, enabling runoff and rainwater to collect. They are not influenced by groundwater. – ex: Lakes Boomanjin, Birrabeen and McKenzie (Boorangoora)
Window lakes are found at low elevation, forming where the ground surface dips into the water table. – ex: Lake Wabby
Barrage lakes form when a mobile sand dune dams a watercourse or encroaches on a lake. Lake Wabby is both a barrage and window lake. The world’s largest perched lake (Boomanjin) and some of the world’s highest lakes (Boomerang Lakes, 120m above sea level) are found on the Island.
Fraser Dingo 4wd Adventure’s Vision Statement: To share our commitment, understanding and passion for the protection of the natural environment, so all our customers can see and experience the uniqueness of nature now and into the future.
Fraser Dingo 4wd Adventures continue to operate with our vision, while we also expand to improve our range of products so we are offering a quality eco experience for all our customers. To do this we will be looking at involving research opportunities to Environmental Science Undergraduates from Griffith University to be part of our tours, with the opportunity to access Fraser Island and develop their guiding experience. We are also planning to involve the local Butchella community with seasonal “Bush Tucker” guided hiking tours.
PINK is GREEN as magenta pink is our signature colour we are working towards establishing an eco-focus around letting our customers know that if they chose pink they are choosing a green option and helping the environment. This eco focus will be shown through; stickers in cars that highlight why we don’t have air-conditioning in our vehicles. Less fuel consumption, no need to re-gas, keeps cost down for customer and encourages them to open their window and enjoy the pristine air of World Heritage Fraser Island. Encourages more involvement with nature.
PINK is GREEN initiative will also be explored via being involved in carbon neutral projects, where we donate funds towards tree planting programs or Biodiverse Reforestation Carbon Offsets, with Green Fleet
