The boat slips away from the Reef Fleet Terminal and Cairns melts to a low, leafy horizon; salt and sun sharpen as Green Island grows from the ocean like a ringed green coin. On approach the reef shows its personality—patches of living coral that dare you to look closer, lagoons that push a slower rhythm, and a compact rainforest that sits cool behind the beach.
