After Sydney, we took a flight up to Cairns. The city is dreadful in itself, but because of the enormous opportunities to do all kinds of cool things in the surrounding areas, and quite the nightlife Cairns has to offer, it is a must-visit if you ask me.
One of the first things we did was to take a day trip to the snorkeling paradise of Green Island, located just in the inner reef of the Great Barrier reef. Here we sunbathed on a superbly stunning beach, watched numerous turtles come up for air close to shore in the intense turquoise water, snorkeled in stunning coral gardens hosting millions of colorful underwater creatures, and snorkeled with turtles. Truly a beauty on earth! If it wasn't invaded by half of the Chinese population, it'd be even better. Paradise when you find a secluded spot for yourself.
