Green Island Conservation & Caring for the Reef

Visiting soon? Read about the Great Barrier Reef at Green Island and our snorkelling tips.

Green Island is a living coral cay,  a rare place where rainforest, beach and reef meet just off the coast of Cairns. It sits within the Great Barrier Reef Marine Park and is protected as national park, and its beauty depends on careful conservation and on every visitor treating it gently. Understanding how the island is cared for, and the small choices that make a difference, helps keep it healthy for the future.

A Protected Coral Cay

The island and the waters around it are managed to protect the reef, marine life and rainforest. Zoning within the Marine Park, national park status on the island, and the work of rangers and operators all help conserve the environment. These protections exist because coral cays are fragile and slow to recover from damage.

The Reef and Its Marine Life

The fringing reef at Green Island is home to corals, reef fish, giant clams, rays and sea turtles. Corals are living animals that grow very slowly, so even small amounts of damage take a long time to heal. Turtles and other wildlife are best enjoyed from a respectful distance, without touching, chasing or feeding.

How Visitors Can Help

Small habits add up. Use reef-safe sunscreen and apply it well before entering the water, avoid touching or standing on coral, keep your distance from wildlife, never feed marine animals, and take all your rubbish with you. Reducing single-use plastics and following the guidance of operators and rangers all help protect the reef.

Caring for the Island’s Rainforest

Green Island’s rainforest is part of what makes it special. Staying on marked paths and boardwalks, not disturbing plants or wildlife, and leaving no trace helps protect the fragile island ecosystem above the waterline as well as below it.

Frequently Asked Questions

Is Green Island a protected area?

Yes. Green Island holds national park status, and the surrounding reef lies within the Great Barrier Reef Marine Park. These protections, along with zoning and the work of rangers and operators, help conserve the island’s rainforest, reef and marine life.

Why is reef-safe sunscreen important at Green Island?

Because the fringing reef sits right at the shoreline, sunscreen easily washes off swimmers and into the water. Reef-safe products avoid certain chemicals that can harm coral. Choosing reef-safe sunscreen and applying it well before you swim is a simple way to protect the reef.

How can I help protect the reef and island during my visit?

Use reef-safe sunscreen, avoid touching or standing on coral, keep a respectful distance from turtles and other wildlife, never feed marine animals, reduce single-use plastics, and take your rubbish with you. On land, stay on marked paths to protect the rainforest. Following operator and ranger guidance helps too.

Is it okay to touch the coral or feed the fish?

No. Touching or standing on coral damages the reef and can injure you, and feeding fish disrupts natural behaviour and the reef’s balance. Coral grows very slowly, so it’s important to look without touching and to let marine life feed and behave naturally.

Why does conservation matter so much at a place like Green Island?

Coral cays like Green Island are fragile and recover slowly from damage. The rainforest, reef and wildlife are all interconnected, so protecting them keeps the whole ecosystem healthy. Responsible visitor behaviour, combined with formal protections, helps ensure the island remains beautiful and thriving for future generations.
