Whale Watching & Swim With Whale Tours from Cairns and Port Douglas

admin on April 13th, 2026

Cairns and Port Douglas offer some of Australia’s most unique whale watching experiences. From family-friendly reef cruises to specific whale watching day tour and specialist dwarf minke whale expeditions, Tropical North Queensland combines reef adventures with unforgettable marine wildlife encounters.

With the annual migration of the Dwarf Minke Whales and the giant Humpback Whales as they head from the cold waters of the Southern Antarctic to the warmer waters of the Great Barrier Reef to calve and find a mate.

The best months to see the whales in Cairns and Port Douglas is from June to July for Dwarf Minke Whales, and July to August for the giant Humpback Whales.  The Great Barrier Reef World Heritage area provides a safe and protected breeding sanctuary for approximately 30 species of cetaceans (whales and dolphins).   That is approximately 35% of the world’s total living cetacean species.

The Humpback Whales and Dwarf Minke Whales are protected in this coastal area of Australia.  Boats, and other water vessels including kayaks and stand up paddleboards, are not permitted to get too close to these gentle giants, and thankfully there whale and dolphin watching regulations that all users of the Great Barrier Reef waters need to abide by for the protection of these majestic marine creatures.

During the tropical winter months in Cairns, many of the reef boats travelling out to the reef report whale sightings which adds an extra special touch to their passenger’s dive and snorkel tours out on the reef.

Swim With Whale Day Tours & Dive Expeditions

Swimming with the Dwarf Minke Whales is an amazing and different experience to the day tours to go Humpback Whale Watching.

As Port Douglas is only place in the world - the 3 swim with Dwarf Minke Whale Day Tours from Port Douglas allows 10 people at a time to be in the water if a Dwarf Minke Whale is encountered at one of the reef sites the vessel is licenced to visit.  Abiding by strict code of practice, a maximum of two surface ropes will be placed in the water with swimmers then positioned 3 to 4 metres apart.

The Dwarf Minkes are very inquisitive, and find us interesting to look at.  There is no need to chase them, they decide how close they want to interact and swim with us, and quite often their curiosity brings them in very close, up to arm’s length even.

These cute whales are known to spend hours with divers and snorkelers showing off and taking a good close look at us and spy hoping in amongst the folks in the water to the delight of the guests.  They are a not like the Humpback Whales who leap out of the water and come crushing down, they seem to be a very docile inquisitive type of whale.

These particular whales are a new species discovered on the Great Barrier Reef only in the mid 1980’s and there is still little known about them.  The tours have a focus on visiting several reef sites and being in the water to see other amazing corals and marine life under the surface.   Even if you don’t see any Dwarf Minke Whales, you can be assured that you will be able to see other incredible sights on your Great Barrier Reef tour.  

Please note - there is NO GUARANTEE that you can swim with whales on these tours - the whales are wild animals and can choose to travel in any direction of preference as they move along on their migration path.

Swim with Whale Dive Expeditions


The extended liveaboard reef tours offer you further opportunities to swim with the whales, and offer you a choice of 3 - 7 night options which are suitable for divers and snorkellers.
