                                           In 1908 a visitor to Green Island wrote in his diary:
                                           “The vegetation then was very small, 5 to 6 feet high and you could practically
                                           look over it”.

                                           This means the large trees that you see today are just over 100 years old.

ECOTOURISM ON GREEN ISLAND

Green Island Resort is dedicated to caring for the island while delivering the best and most enjoyable ecotourism
experience for visitors. Ecotourism is defined as a tourism experience that takes place surrounded by nature, has
negligible impacts on the environment, and provides opportunities to appreciate and learn about the natural area.

The depths of the swimming pools are limited to 2.2 metres
so they do not interfere with the water table beneath the
island.

Raised Boardwalks
Buildings are linked with timber
boardwalks to eliminate problems
with compaction and erosion. These
boardwalks also allow animals to move
freely along the forest floor and do not
interfere with tree root systems.

As with the resort buildings, boardwalks
were built around existing trees. The gaps
between the boards allow rainwater to
fall freely to the ground to replenish the
freshwater lens beneath the island.

GREEN ISLAND MANAGEMENT

Management of Green Island is very complex. Many different agencies share jurisdiction over Green Island. Although a
large portion of it is National Park, there are diverse tourism and research interests on the island as well.
Even though the island is only very small (12 hectares) it has one of the most complicated management systems of any
of the Great Barrier Reef islands, having state, federal and local laws governing various aspects.

GREEN ISLAND MANAGEMENT

THE GREEN ISLAND REEFS

All reefs within the Great Barrier Reef
Marine Park have been zoned under
the GBR Zoning Plans. Green Island’s
surrounding reefs are classified as
Marine National Park, or ‘Green Zone’.
Additionally, a large area away from
tourist activity, is classified as a Scientific
Research Zone.

A Green Zone is a ‘no-take’ area which
means that removing things such as
shells and activities such as fishing are
illegal, but the area can be used for
low impact activities including diving,
snorkelling and boating.

MANAGING CHEMICALS ON GREEN ISLAND

Green Island Resort limits the use of chemicals. Green Island is a very fragile sand cay ecosystem that can be harmed
by harsh chemicals. The Resort has a strict Chemical Management system that regulates what types of chemicals can
be used, how much can be used, how they are stored and how they are disposed

WATER MANAGEMENT

Natural freshwater on Green Island is very limited. Since there are no natural springs or lakes on the island and all the
vegetation relies on rainfall for survival, the resort must provide its own water. Strict water restrictions prevent the
resort from catching any rainwater or tapping into the underground freshwater lens.

MAKING FRESHWATER - Desalination Plant

Since there are no natural springs or rivers on Green Island, freshwater is very limited. All natural freshwater on the
island comes from rainfall. Demand for freshwater by the island’s plants is very high - without the water, the rainforest
would die. To prevent any conflicts with the natural environment, Green Island Resort produces its own water.
