The Great Barrier Reef - Experience World Heritage

The Great Barrier Reef is a UNESCO World Heritage Site, and it is recognized for its outstanding universal value. It is one of the most important natural ecosystems on the planet, and it is a critical source of food, livelihoods, and tourism for the people of Australia. The reef is attributed with significant cultural and historical heritage values under UNESCO’s World Heritage framework, along with meeting all 4 natural criteria which include:

  • Natural beauty and natural phenomena
  • Major stages of Earth’s evolutionary history
  • Ecological and biological processes
  • Habitats for conservation of biodiversity

Located off the coast of north-eastern Australia, the Great Barrier Reef spans over 2,300 kilometres (1,400 miles) along the Queensland coastline. It is made up of over 2,900 individual reefs and 900 islands, and it covers an area of approximately 344,400 square kilometres (133,000 square miles).

Home to over 1,500 species of fish, including clownfish, giant trevally, and barracuda, as well as over 600 species of hard and soft corals, the reef is also home to dozens of species including dugongs, dolphins, and humpback whales. The reef is also an important breeding and nesting site for sea turtles and seabirds, such as the magnificent frigatebird.

Aboriginal and Torres Strait Islander peoples have a long history of connection with this region which carries on today with care for Sea Country through cultural practices and knowledge. You can read more about the Great Barrier Reef’s traditional owners here.

The reef is managed by and cared for by GBRMPA, the Great Barrier Reef Marine Park Authority. They work alongside the traditional owners, marine scientists, government departments, local tourism operators and individuals to protect the reef from environmental threats and preserve it from future generations.

All commercial day tours to the Great Barrier Reef pay an included EMC, or Environmental Management Charge, which goes directly to GBRMPA to fund the day-to-day management of the marine park. So by visiting the Frankland Islands with us, you’re contributing to the protection of the reef!

Protecting the Great Barrier Reef

The Great Barrier Reef is primarily protected by the federal Environment Protection and Biodiversity Conservation Act 1999 and the Great Barrier Reef Marine Park Act 1975. It is managed through a comprehensive multiple-use zoning plan, with 33% of the park highly protected.

Unfortunately, the Great Barrier Reef is facing several significant environmental challenges. These challenges include significant pressures from climate change, pollution, overfishing, and coastal development. 

‘Climate change’ refers to long-term shifts in global temperatures and weather patterns, largely due to greenhouse gas emissions driven by human activity. This results in increased severe weather in certain places, melting of ice polar regions increasing sea level and many other potential impacts. For the reef this may result in higher water temperatures leading to coral bleaching, ocean acidification, damage from weather events and habitat changes in the future. Read more about these potential threats here.

Despite these challenges, several conservation and restoration efforts are underway, including initiatives to reduce pollution, promote sustainable fishing practices, and restore damaged reef habitats. Blueprint 2030 is a plan that focuses on the entire reef ecosystem to build climate resilience and adaptation for future changes. These plans highlight the importance of biodiversity, and these plans are critical for ensuring that the Great Barrier Reef can continue to thrive.

#2

You may think of coral reefs when you think of the Great Barrier Reef, but they only make up about 7% of the entire Marine Park.

#3

The Great Barrier Reef Marine Park is almost as big as Germany - laid on top it would cover 98.6% of the country.

#4

The Great Barrier Reef is home to six of the world’s seven turtle species and contains 25% of all known marine species in the world.

Fabulous experience. Staff had tons of enthusiasm and took great care of us. The person that lead the snorkel tour (I didn’t catch her name but she is from Missouri) was particularly great. Do not hesitate to take this tour. The snorkeling was awesome and we had plenty of time. Even saw a manta ray!

Very glad we chose the Frankland Islands for our trip to the reef. Enjoyable river cruise with crocodiles and friendly crew. The island is beautiful and the snorkelling was excellent with sharks, turtles, Moray eel and plenty of fish and coral just offshore

Truly awesome! Much better and less crowded/touristy than the Outer Reef/Green/Fitzroy tours for a more secluded feel. All inclusive makes it stress free. Tour guides were fun and informative. River entrance adds the croc dimension. Definitely recommend this tour more than the others or at least do both, but don’t miss this.

Amazing day out at Frankland Islands. The staff were so great with the kids (they especially loved the pirate treasure hunt)! We had a wonderful time on the glass bottom boat, snorkelling with turtles and kayaking. Thanks to the great crew, especially Riley & Jimmy who made our day!

Excellent tour. Frankland Islands are fascinating. River cruise is very interesting way to start a trip to the Great Barrier Reef. Short ocean crossing to the islands. The staff are highly qualified, attentive and friendly. Tour is very well organised.

A superb day out on the reef on a deserted island. All inclusive experience including hotel transfer, lunch and all snorkelling kit etc. first class tour guides offering insight, humour and great organisation. Walk around the island, take in the breath-taking views, snorkel for marine life and befriend some baby black tip reef sharks! They even threw in a croc sunbathing on the way back. Well worth the money!

The whole day was great. Starting in the river and then going into the ocean gave a different perspective than other cruises. Saw a crocodile on the way back in the river. Highly recommend this company and cruise.

A perfect day with a totally engaged and friendly staff. I can recommend this to everyone, so much better with the small group and more individual than all the other snorkeling tours mass tourism tours.

Thanks to the whole Frankland Islands team, we had a great day out. Everyone was so friendly. Max especially was great with the snorkel safari and the island walk; he was so knowledgeable and genuinely interested in what he was showing us. We would highly recommend this.
