THE GREAT BARRIER REEF
As the largest living structure on the planet, the Great Barrier Reef is incredibly rich and diverse, stretching 2,300 kilometres.
The surrounding reef on Lady Elliot Island is a 'Green Zone' which is home to the most diverse, colourful and intriguing marine animal and reef life.
The Great Barrier Reef is also unique as it extends over 14 degrees of latitude, from shallow estuarine areas to deep oceanic waters. Within this vast expanse are a unique range of ecological communities, habitats and species – all of which make the Reef one of the most complex natural ecosystems in the world.
