Hervey Bay Whale Watching Cruise with Marine Scientist

Great Sandy Straits Marina, Urangan: the departure point

The cruise leaves from Great Sandy Straits Marina on Buccaneer Drive in Urangan, the eastern end of Hervey Bay and the base for the town's whale fleet. You check in at the marina 30 minutes before departure, meet the scientists and crew, and board a 12-metre rigid inflatable boat built for small groups, with forward-facing seats under shade and toilet facilities on board. There is no hotel pickup; the marina is about 15 minutes by car from the Esplanade and has parking.

If you are deciding how to get to the whale watching departure in Hervey Bay, taxis and local buses serve Urangan, and many guests combine the morning cruise with a walk along the nearby Urangan Pier afterwards. Seats are pre-assigned for balance on the boat, and the crew ask you to stay in your section while the vessel is moving at speed.

Along the western coast of K'gari

Leaving the marina the boat runs north along the sheltered western shore of K'gari, formerly Fraser Island, the world's largest sand island, with its dunes, forest and long sandspits sliding past on the starboard side. This stretch of the Great Sandy Marine Park is calm and fast to cross, and it gives you panoramic views of the island while the scientists explain the geography of the bay and why the whales come here.

Keep watching the water on the way out: bottlenose dolphins often ride the bow wave, green turtles surface for air, and dugongs feed on the seagrass meadows in the shallows. The run to the whale grounds takes roughly 30 to 45 minutes depending on where the whales are that day, and the crew stay in contact with other boats to head straight to the action.

Platypus Bay: the whales' resting ground

Platypus Bay is the wide, sheltered bay between the western coast of K'gari and the open water of Hervey Bay, and it is unlike any other stop on the humpback migration. Instead of passing through, the whales pause here for days on their way south from the breeding grounds, resting, socialising and letting their calves build strength in calm, protected water. In 2019 Hervey Bay was recognised as the world's first Whale Heritage Site for this reason, and it is part of the Great Sandy Biosphere and marine park.

Being in the bay with the engines off, watching a mother and calf drift alongside the boat, is the heart of this Hervey Bay whale watching cruise. The whales are often curious and approach the vessel on their own, which is why the low sides and water-level seats of the boat matter so much: you look at a whale eye to eye rather than down from a high deck.

Humpback behaviour and the science on board

The East Australian humpback population migrates each year from Antarctic feeding grounds to the warm waters of the north to breed, then returns south past Hervey Bay between July and October. Your guides are marine scientists who identify the behaviours you see, from breaching and tail slapping to pectoral waving and spy hopping, and explain what each one is likely to mean. They also share findings from ongoing research into the whales' movements, health and song.

Underwater hydrophones are lowered from the boat so you can hear the whales' calls live, something very few whale tours anywhere offer. Children receive a junior naturalist activity booklet to follow along, and the commentary is pitched for both adults and young visitors. Part of what you pay supports whale research, marine education and ocean conservation in Australia, which is one of the best reasons to choose this particular cruise.

Morning or sunset: choosing your cruise

The default option departs at 08:00, when the bay is at its calmest and the light is clear for photographs; mornings are also when whales are most often seen playing and breaching. A sunset cruise departing in the mid-afternoon is available as a second option, finishing with the sun going down over the Great Sandy Strait and golden light on the water as whales surface around the boat. Both run for about three hours.

Snacks and soft drinks are served on each cruise, and the shaded forward seats keep you comfortable on sunny days. Dress warmly, because the boat moves quickly and the wind on the water is cooler than on shore even in spring; a jacket, hat and sunglasses are the three essentials, and a camera with a strap is the fourth.
