The Great Barrier Reef
The Great Barrier Reef, off the coast of Queensland in northeastern Australia, is the world’s largest coral reef system and a UNESCO World Heritage Site. Stretching over 2,300 kilometers, it comprises more than 2,900 individual reefs and almost 900 islands. Since its protection as a Marine Park in 1975, it has sheltered an incredible variety of marine creatures: clownfish dart among staghorn corals, green sea turtles glide above the seabed, and reef sharks patrol the deeper channels. Brain, table, and elkhorn corals form vast underwater gardens teeming with life. Visitors snorkel in crystal-clear turquoise waters by day and study bioluminescent plankton at night. Research teams aboard vessels monitor coral bleaching caused by rising sea temperatures and ocean acidification. On land, islands such as Hamilton and Lizard feature sandy beaches, rainforest hikes, and cultural tours led by Indigenous rangers sharing centuries-old ecological wisdom. Historic shipwrecks from early explorers rest on outer reefs near old lighthouse stations. Conservation efforts focus on controlling crown-of-thorns starfish outbreaks, reducing agricultural runoff, and promoting eco-friendly tourism. Millions travel annually to marvel at sunrises over the reef, yet its future depends on global climate action and local stewardship.
