A tropical island paradise
This National Park is home to over 120 native plant species, colourful bird life and surrounded by coral gardens and abundant marine life to explore.
Just 45 minutes across the Coral Sea by fast catamaran from Cairns, Green Island is a beautiful 6000 year old coral cay located within the Great Barrier Reef Marine Park – one of the Seven Natural Wonders of the World.
It’s the only coral cay on the Great Barrier Reef with a rainforest growing on it!
Green Island and its reef are very close to the mainland, lying only 27 km (16 miles) from Cairns.
The island sits on the north-western edge of the reef flat.
The surrounding reef is classified an ‘inshore patch reef’.
The reef surrounding Green Island supports a diverse range of habitats and marine life.
There are two significant habitats:
- The sea grass beds in the shallows
- The reef that starts shallow and continues into the depths.
Sea grass beds support a wide range of animals. From juvenile fish that use the grass for protection from predators to large sea turtles and dugong that feed on the sea grass.
The reef around Green Island has over 190 different types of hard corals and over 100 types of soft corals.
With a circumference of just 1.6 km, the Island is home to over 120 species of plants, including a unique mixture of coastal and rainforest plants.
The coastline is ringed by short, scrubby coastal vegetation that can survive drier conditions along the beach.
When you step a few feet in to the centre of the island the vegetation changes abruptly to a dense and shady vine-thicket rainforest.
Of the 300 coral cays on the Great Barrier Reef, Green Island is the only one with a rainforest.
Coconut trees are not thought to be native to the island but were introduced to the island in 1889.
The reason for this was to provide food, drink and shelter for fishermen and stranded sailors.
