Dunk Island lies offshore from South Mission Beach in Far North Queensland, reachable by boat, and its three dive sites offer shallow reef snorkelling and diving across a range suitable for beginners and intermediate divers. Muggy Muggy Beach provides the most sheltered entry, protected by a rainforest headland, while Coral Bay reaches to twelve metres for those wanting more depth. Currents are generally mild but variable, and jellyfish are a hazard during stinger season from November to May. Saltwater crocodiles are noted as a regional hazard. Green Sea Turtle, Napoleon Wrasse, Whale Shark, Whitetip Reef Shark, and Hairy Frogfish are among the recorded species.
Monthly water temperature across Dunk Island's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water is warmest through the wet season months and cools somewhat in the dry season mid-year, though it remains warm enough for a shorty or thin wetsuit throughout. Stinger season from November to May requires the use of a stinger suit for exposed skin at all sites.
Water temperature around Dunk Island ranges from about 23°C in July to 29°C in January, based on satellite sea-temperature data for its dive sites.
In the warm season (about 29°C) a rash guard or 3mm shorty is comfortable in Dunk Island; in the coldest months (about 23°C) step up to a 3mm full suit.
