10Fraser Island, Australia

Located off the coast of Queensland, Fraser Island might seem like paradise with its crystal-clear waters and lush rainforests, but it’s considered one of the most dangerous beaches in the world. The waters surrounding the island are home to great white sharks, dangerous jellyfish like the Irukandji and box jellyfish, and aggressive saltwater crocodiles.

On land, Fraser Island is inhabited by the dingo, Australia’s wild dog, which can pose a threat to visitors. Despite these dangers, the island remains a popular tourist destination—just one that requires extreme caution.
