Weekend escapes to Queensland are Good to Go! Queensland is blessed to have one of the world’s greatest natural wonders located in our backyard but, surprisingly, many are yet to visit the Great Barrier Reef. So, what makes the Great Barrier Reef stand out from the rest? Claiming the title of the largest coral reef system in the world, the Great Barrier Reef stretches over 2,300 kilometres. It is also one of the most biologically diverse ecosystems made up of 600 islands, 3,000 coral reefs, 300 coral cays and millions of marine life. You could spend a lifetime exploring the Great Barrier Reef and you still wouldn’t be able to visit all 344, 400km2 of it.
