Destination guide
Sail, dive and snorkel the heart of the Great Barrier Reef
Currently Viewing:
Overview
The Whitsundays are a warm water reef playground where sailing, snorkelling and laid back resort life meet. Base in Airlie Beach or Hamilton Island to reach fringing reefs around Hook and Hayman, outer walls at Bait and Hardy Reefs, and beaches like Whitehaven. Water stays warm year round, visibility shifts with wind and rain, and everything sits inside the Great Barrier Reef Marine Park.
The Whitsunday Islands sit in the middle of Australia's Great Barrier Reef, an easy hop from the mainland hub of Airlie Beach or resort islands like Hamilton Island. Short passages, protected anchorages and beaches such as Whitehaven make this one of the world's best known sailing grounds.
Underwater you get fringing reefs close to shore and outer reef walls farther offshore. Around Hook and Hayman Islands you can dive and snorkel coral bommies and ledges at places like Manta Ray Bay, Blue Pearl Bay and Luncheon Bay. Day boats and liveaboards run to Hardy and Bait Reefs, where walls drop into deep blue water and visibility is often higher.
Air temperatures usually sit in the mid 20°C range in winter and around 30°C in summer. Sea temperatures hover from about 22°C in the coolest months up to 28°C in late summer. Visibility is often roughly 10 m to 20 m depending on weather and tides.
Sheltered bays offer gentle conditions for beginners, while outer reef walls and exposed headlands suit confident divers and freedivers comfortable with chop and current. Non divers can spend days sailing, on beaches, scenic flights and hikes, so it works well for mixed groups.
Highlights
Field notes from guides and contributors on what stands out immediately.
Time your Whitehaven trip so you reach Hill Inlet near mid tide, when swirling sandbars and channels show the strongest contrast from the lookout. Early or late departures reduce heat and crowds.
If you only do one big day out, make it an outer reef trip to Hardy or Bait Reef. Platforms, cats and liveaboards provide long windows for snorkelling and diving over deeper walls and bommies that feel different to island fringing reefs.
Join tours that include commentary on the Whitsundays Whale Heritage Area status and Traditional Owner perspectives on sea country, adding context to the strict whale approach rules.
