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.
Trip callouts
Airlie Beach, Shute Harbour, and Hamilton Island launch trips to fringing reefs, Whitehaven Beach, and outer GBR sites like Bait and Hardy.
Seas sit roughly 22°C–28°C, so snorkel and dive any month with light exposure.

Why the Whitsundays for Scuba Diving
Scuba diving in the Whitsundays mixes relaxed island life with classic Great Barrier Reef walls and bommies. From Airlie Beach, boats visit fringing reefs around Hook and Hayman, with sites like Manta Ray Bay, Luncheon Bay and Blue Pearl Bay 2 offering turtles, Maori wrasse and easy multilevel profiles. Outer reef trips and liveaboards reach Hardy and Bait Reefs for deeper walls, swim throughs and bigger schools of fish.

What to do in the Whitsundays when you are not diving
Warm water, easy boat access and a growing local community make the Whitsundays a quiet favourite for Australian freedivers. Fringing reefs around Hook Island, Black Island and Butterfly Bay offer natural lines, swim throughs and walls in the 5 m to 25 m range, while outer reef trips provide blue water dives with bigger fish.
The Whitsundays are one of Queensland's easiest snorkel destinations, with shallow coral gardens fringing many islands and day boats that specialise in beginner friendly trips. Sites like Manta Ray Bay, Luncheon Bay and Langford Reef offer turtles, bright coral and calm bays. Pontoon based trips to Hardy Reef add lifeguards, ladders and semi subs so even nervous swimmers can enjoy the reef.
Topside, the Whitsundays are about sailing, beaches and big views. Spend a day on Whitehaven Beach and hike to the Hill Inlet lookout, sail a bareboat yacht through the islands, or base on Hamilton Island for buggies, restaurants and day trips. Scenic flights from Airlie Beach or Hamilton Island reveal Heart Reef and swirling sandbars from above, and winter brings humpback whales to the channels.
