The reef is home to over 1,500 species of fish, 400 types of coral, 4,000 species of mollusk, and 240 species of birds
It's actually made up of nearly 3,000 individual reef systems and hundreds of islands, including 600 continental islands
The reef is older than most human civilizations — parts of it are over 20,000 years old
Six of the world's seven species of marine turtle can be found on the reef
The Great Barrier Reef Marine Park covers 344,400 square km — roughly the size of Italy
Top Sights
Outer Reef (from Cairns)
🐠Day trips to the outer reef offer the best coral and clearest water. Operators like Quicksilver and Reef Magic take you to pontoons with snorkeling, diving, and glass-bottom boat viewing. Book the earliest departure for calmer seas.
Whitehaven Beach
🏖️Consistently ranked among the world's best beaches — 7 km of pure white silica sand with swirling turquoise tidal patterns. Hill Inlet lookout is the iconic photo spot. Accessible by boat from Airlie Beach.
Heart Reef
🐠A naturally heart-shaped coral formation in Hardy Reef, best seen from a scenic helicopter or seaplane flight. You can't snorkel here (it's protected) but the aerial view is iconic.
Green Island
🏝️A beautiful coral cay just 45 minutes by fast catamaran from Cairns. Great snorkeling right off the beach, a small rainforest walk, and a underwater observatory. Good for families and non-swimmers.
Fitzroy Island
🏝️A continental island with excellent fringing reef snorkeling, rainforest hiking trails to the summit, and a sea turtle rehabilitation centre. Less crowded than Green Island and more natural.
Daintree Rainforest
🌿The world's oldest tropical rainforest meets the reef — the only place on Earth where two World Heritage sites sit side by side. Take a river cruise to spot crocodiles, then head to Cape Tribulation beach.

Safety Breakdown
Very Safe
out of 100
The reef is generally safe for visitors, but the marine environment requires respect. Marine stingers (box jellyfish) are present November-May. All reputable tour operators provide safety briefings, equipment, and trained crew. Always listen to your dive instructor.
Things to Know
- •Wear a stinger suit (lycra body suit) when swimming November-May — tour operators provide them
- •Don't touch the coral — it damages the reef and some coral can sting or cut badly
- •Apply reef-safe sunscreen (zinc-based, no oxybenzone) — chemical sunscreens damage coral
- •Stay hydrated — dehydration and seasickness are the most common issues on reef trips
- •If you feel seasick, stay on deck and focus on the horizon — take medication before boarding
- •Crocodiles inhabit rivers and coastal areas — never swim in rivers or murky estuaries
