Aerial view of Great Barrier Reef in Australia

Australia is home to vastly different landscapes, from the arid desert that makes up the Outback to lush green rainforests filled with unique wildlife to pristine beaches surrounding its coastline. I've been lucky enough to visit many of these features, but nothing compares to the Great Barrier Reef. This beautiful expanse of coral gardens and marine life has been listed on the UNESCO World Heritage Register for a reason.

10 Secret Islands on Australia's Great Barrier Reef

The Great Barrier Reef enjoys an average temperature of 86 degrees year-round, though it sometimes gets to 70 in winter. Due to its beauty and these conditions, the reef receives almost 7 million visitors yearly, meaning some areas will be more crowded than others. If you'd prefer a quieter vacation, here are some lesser-visited islands where you can have a more relaxing vacation while enjoying this natural wonder.

While the weather is excellent year-round, there are certain months when swimming is slightly more restrictive than others due to Box Jellyfish inhabiting the area. To get the most out of your vacation, the best time to visit is between April and October—the colder months in Australia.
