Australia
Great Barrier Reef
The Great Barrier Reef is the world's largest coral reef system, composed of roughly 2,500 individual reefs and 900 islands extending 2,000 kilometres along Queensland's coast.
The coral reefs hold a huge biodiversity, with dugong, whales, dolphins and turtles among the most notable marine species. They provide some of the most spectacular underwater scenery on earth with 400 species of coral and 1,500 species of fish.
Community Perspective: You can go and see it from a glass bottom boat, by snorkeling, diving or just straight from the boat. Cairns is a good starting point for these tours, as are the Whitsunday Islands (which come out better in comparison).

Affected by Climate Change
Climate change and global warming are responsible for the rising of seawater temperature, producing bleaching, a phenomenon affecting coral by which they lose their natural color and die. It is now (2020) assessed by IUCN as having a “critical” outlook. In 2020, a study has found that Australia's Great Barrier Reef has lost more than half of its corals since 1995 due to warmer seas driven by climate change. -

My visit was quite a touristy experience, since I visited the Great Barrier Reef several times over the years on tourist boats, that started in Townsville. I would recommend a visit for people, who want to snorkel to see the reef up close. Also, they should be prepared for high swells, when going out in the small boats. On the boat you will get an introduction to the reef as well as to the danger of extinction it is exposed to.

I visited this WHS in December 2017 and January 2018 from Hamilton Island and from Cairns. In all I dedicated a week to this extensive WHS to be able to cover different areas and features of this marine WHS by boat, by plane and by helicopter.
Even though I travelled to some of the most beautiful marine areas in the world (ex. French Polynesia, New Caledonia, Maldives, Seychelles, Caribbean), none are comparable to the Great Barrier Reef not only in terms of size but in terms of the different hues of blue/turquoise, the clarity of the water, the variety and amount of marine life. This applies both underwater and from above. Since we visited during stinger season, we wore a stinger suit when snorkelling to be on the safe side. Being such a vast area, you get to see and experience different things depending from where you're based.
The World Heritage Area Boundary withing the GBR Marine Park stretches from beneath the Torres Strait to just above Fraser Island excluding harbours and islands. For the first 5 days we stayed on Hamilton Island, one of the Whitsunday Islands, and every day we did a different excursion to the Great Barrier Reef (GBR). Already from my window seat, flying from Brisbane, I enjoyed an incredible aerial view of two of Australia's great WHS - Fraser Island and the GBR. First I saw never-ending sandy beaches, dunes and trees. Then the sheer beauty of the GBR and the Coral Sea islands and …

The Great Barrier Reef is as impressive a natural wonder as its name suggests, a wonderland of marine life stretching almost 1400 miles along the northeast coast of Australia. When I planned my trip to Australia in 2012, this was one of the sights I was determined to visit, and it was as beautiful as I had hoped. I used Cairns as my departure point for a full-day snorkeling and snuba tour of the reef. The guides were helpful to point out starfish and giant clams, as well as a shy octopus blending in with a nearby rock. Hidden amongst the anemone were colorful clownfish, while silver schools of mackerel swam above. Our tour also saw reef sharks and stingrays, although we kept a safe distance. I was particularly impressed with the coral, which was brightly colored and magnificent to behold; I'm glad I saw it in 2012 before the recent bout of coral bleaching struck in 2016. The warming ocean temperatures off the coast of Australia are a valid concern, and I'd hate to see long-lasting impact on the unique biodiversity of the reef. Australia is full of wonders on land and sea, and I found the Great Barrier Reef to be an unforgettable marine adventure.
Logistics: The Great Barrier Reef stretches from the Torres Strait to Fraser Island. Tours of the reef can be arranged in cities and towns like Cairns, Townsville, or Port Douglas.

The Great Barrier Reef was one of the few things I knew about Australia before I decided to go there and started planning my trip. Of course I had to go and see it, although I am not a water person and I don't like swimming in the ocean. So when I stayed in Cairns, I chose a tour operator offering trips including a glass bottom boat, and I liked it. I am sure it is nothing like snorkeling, but still I enjoyed what I saw and was fascinated by the underwater world.
Later, when visiting the Whitsunday Islands, I did another tour and this one was even better because the water was so clear and still that I could see the corals straight from the boat, without having to use the glass bottom.
I think I don't have to write anything else - it is famous enough already, and a "must see" for most people when visiting Australia!

I'm not much of a swimmer but I wouldn't go to the Great Barrier Reef without snorkelling. I'm so glad I was up for it because it was quite amazing to see the different varieties of fish! From Airlie Beach, I took a two-day boat trip out to the Whitsundays. I got a bit seasick but it was worth it, especially to come into contact with rainbow lorikeets!

What a place this is! I'm not much of a marine person, but I don't think I'll ever forget my visit to this part of the world. Just go, you won't regret it.

You could be forgiven for assuming from the other posts that only Australians would visit Great Barrier Reef, but that´s not quite true :-)
I´m not much of a sailing/diving enthusiast, but I did do a boattrip from Cairns to the Reef with some snorkeling, and I must admit it was really fantastic. You could see lots and lots of the most bizarre and colorful fish and corals, as well as big sea turtles, all in an evidently unharmed environment, despite the danger that global warming poses to this great site. If I decide to learn to dive, I´d probably come back here.

I visited the Great Barrier Reef via a liveaboard dive boat in March 2005. I've been diving all over the world, but this place tops them all if there was an "overall best" category. Marine life was prolific and varied and conditions were fantastic. It truly lived up to its name as being "Great".
