Whale watching in Hervey Bay is one of Australia’s greatest wildlife experiences. Every winter, thousands of Humpback whales arrive in these calm waters to rest, give birth and nurse their calves before continuing their migration to Antarctica. During the whale season, the bay comes alive with playful calves, curious Humpbacks and close encounters.

On many trips, whales approach the boat, giving us unforgettable moments with these gentle giants.

Add blue skies, beautiful waterfront accommodation, delicious food and tropical cocktails overlooking the harbour and you have the perfect destination for a wildlife getaway.

Whales in Hervey Bay

On their return journey, many whales spend a few days in Hervey Bay’s calm, sheltered waters. This makes Hervey Bay one of the best places in the world to witness the longest animal migration in history. Whales are now so comfortable interacting with local whale-watching boats that many operators guarantee a whale sighting or a full refund.

Our Whale Watching Boat

We booked our whale-watching tour with Freedom Whale Watch. Freedom III is a comfortable 58-foot catamaran. We departed from the Sandy Straits Marina at 9:30 am. After an introduction to the crew and a safety brief, the boat steams out of the Great Sandy Marine Park toward the whale sanctuary of Platypus Bay.

While travelling, Keith, the skipper, comments on the whales, their conservation and the local area, including Fraser Island. The weather is perfect and Keith tells us it’s only going to get better throughout the day.

The boat is comfortable, with whale-watching available on all three decks. Nothing on board is off-limits, including the wheelhouse. The fantastic crew, Louis, Billy and Ivan, are helpful and go out of their way to keep everyone comfortable.

The crew serves a morning tea of homemade profiteroles and freshly baked scones with cream and jam. The crew walk around the boat with plates of delicious food, making sure everyone is full and satisfied! They also carry sunscreen to keep everyone from getting too sunburned.

The Humpback Whales

Not long after arriving in Platypus Bay, we see our first whales! In the distance, we see the blows, like thick mist as the whales exhale. As we get closer, the boat’s engine shuts down. Boat operators follow strict rules and approach the whales gently.

We also see our first acrobatic display: a whale breaching, the most spectacular of all whale behaviours. After the breach, the crew deployed an underwater microphone and we listened to the beautiful, haunting sounds of whales singing.

Mum and Baby Whale

We move on, then stop again when the crew spots more whales. A curious mother and calf swim quietly alongside our boat, giving us a glimpse into the close bond they share. Looking closely, we can even see scars on the young calf—likely from males competing for the chance to mate with its mother.

Keith tells us the calves in the bay are usually between one and four weeks old. It’s not that common for a mother to approach a boat with her baby. More often, a mother and calf are accompanied by an escort—usually a protective male—who positions himself between the boat and the pair.

Mum and baby touch each other with their flippers and swim right up to the boat to take a good look. Sometimes, they do this so Mum can show the baby the boat is dangerous and to stay away from the propellers. While in the warm, sheltered waters, Mum teaches the baby survival skills before heading back to the cold waters of Antarctica.

They swim in and out under the boat, right beside it, then swim away. They swim a little way out. Mum stops to feed the baby! Hanging upside down, with her tail erect, she spends about 15 minutes feeding her baby milk. In this position, the mammary glands are perfectly oriented for her to squirt milk into the baby’s mouth.

After mum and baby move on, we think it can’t get much better than this. Keith starts the boat to move on, but soon changes his mind. Suddenly, the baby begins breaching. He seems full of energy after his milk and is showing off. This is an adorable show!

A tropical buffet lunch is served while watching the whales. Plenty of salads are put out, along with filtered water, tea, coffee, soft drinks, beer and wine.

Playful Whale Antics

After lunch, a pod of whales mug our boat. A mugging is when a pod of whales swims around the boat and it’s a situation where they’re watching us. They chase and play together, swimming on their backs, diving under the boat and coming up on the side. Then they spy-hop, which involves raising their heads to get a better view of what’s happening above the water!

One repeatedly lifts its tail out of the water and slaps it on the surface and another one slaps its pectoral fin. It’s not yet known why they do this. Whoosh! Whoosh! The loud slapping sounds can be heard from afar underwater, so they may be communicating with other whales, warning, flirting, or just for fun!

During the afternoon, we see more whales—at least ten different pods, from baby calves to full-grown adults. A day of breaching, tail slapping, pectoral slapping, belly showing, mugging and spy hopping is part of a day’s whale watching in Hervey Bay!

Whether it’s your first whale watching trip or your tenth, nothing prepares you for the moment a Humpback whale surfaces beside the boat. You’ll remember it long after you return to shore.

After Whale Watching

After a full day of whale watching, Freedom returns to the Marina around 4 pm. Back at the Marina, the perfect weekend doesn’t have to end. The waterfront is lined with cafes and restaurants, making it a wonderful place to relax with a drink or enjoy a delicious meal while reflecting on the day’s whale encounters.

With beautiful views across the Marina and plenty of tempting food choices, it’s the perfect way to finish a visit to Hervey Bay.

Our Accommodation in Hervey Bay

We stayed at the Mantra right on the Marina. Perfect location, with the harbour just outside the door. This makes for an ideal getaway for a couple of days with no need to go anywhere else. We love the atmosphere of the cafes on the Marina, with views of the boats moored below.

Our favourite is Cafe Balaena. We have most of our meals here because it offers delectable dishes and a good selection of vegetarian options.

Our Whale Watching Tour

• Freedom spends the entire day on the bay, giving you more time to enjoy the whales.
• We generally prefer smaller boats, but they can be less stable in rough conditions, increasing the chance of seasickness and making wildlife photography more difficult. They also take longer to reach and return from the whale-watching area.
• Despite carrying more passengers, Freedom is so spacious that it never feels crowded.

Best Time to Visit

• Whale watching season in Hervey Bay runs from late July to early November.
• August and September are generally the best months to see mothers and their young calves resting in the bay’s calm waters.

Tips for a Comfortable Day

• If you’re prone to seasickness, take motion sickness tablets such as Kwells (or your preferred medication) or ginger the night before your trip and again on the morning before boarding. This gives the medication time to work before you head out.
• A wide-brimmed hat and plenty of sunscreen are essential. Although it’s winter, the Queensland sun is still surprisingly strong when you’re out on the open ocean all day. With all the excitement of watching the whales, it’s easy to forget! Fortunately, the crew on Freedom provides sunscreen throughout the day.

💡Whale Watching Information

Whale Behaviours

One of the highlights of whale watching is seeing the different behaviours humpback whales display. Here are a few you may be lucky enough to witness:

🐋 Spy-hopping
A whale lifts its head above the water, possibly to get a better look at its surroundings.

🐋 Tail slapping
A humpback repeatedly slaps its tail against the water, possibly as a form of communication, a warning to other whales, or simply playful behaviour.

🐋 Fin slapping
Whales slap their long pectoral fins on the surface, possibly for communication or play.

🐋 Mugging
A curious whale voluntarily approaches and lingers beside a boat, often giving passengers a close-up encounter.

🐋Fascinating Facts About Humpback Whales

• Watching Humpback whales breach in Hervey Bay is a bucket-list wildlife experience, but what makes it even more remarkable is the incredible journey these gentle giants have already completed.
• Every winter, Antarctica becomes too cold for warm-blooded Humpback whales, and food becomes scarce. They begin one of the world’s greatest migrations, travelling up to 10,000 kilometres to the warmer waters of Australia’s east coast. During this incredible journey, they rarely eat, relying almost entirely on the fat reserves they built up while feeding in Antarctica.
• The migration is also essential for the next generation. Newborn calves are born with no insulating layer of blubber and would not survive the freezing Antarctic waters. Instead, they are born in the warm tropical waters of the Great Barrier Reef, where they can grow stronger.
• A newborn calf is already an impressive sight, measuring 3 to 5 metres long and weighing up to one tonne.
• Most Humpback whales in Australian waters migrate north between June and August, then return to Antarctica in October and November. But they don’t all leave together.
• Instead, the migration unfolds in carefully timed waves. Young males usually head north first, followed by mothers travelling with last year’s calves.
• About 12 days later, a second group, mainly immature males and females, begins the journey. About 20 days after that, mature adults without calves depart.
• The final travellers are the heavily pregnant females. After spending the longest time feeding in Antarctica, they build the greatest fat reserves before setting off on the long journey north to give birth.

• One of the most remarkable moments of the migration occurs when these heavily pregnant females cross paths with newly pregnant females from the first migration group, already making their way back towards Antarctica after mating.
• During the journey north, mothers are also weaning the previous year’s calf. By the time they reach the breeding waters of the Great Barrier Reef, these youngsters are independent enough to survive on their own, although they usually remain close to their mother until the return journey south.
• Even then, the bond between mother and calf remains extraordinary. Throughout the first year, they rarely stray beyond eyeball-to-eyeball or pectoral-fin distance, a remarkable display of trust and protection.
• Humpback whales become sexually mature between five and nine years of age. Females usually give birth to a single calf every two to three years, after an approximately 11-month gestation period.
• Although humpback whales typically live 45 to 50 years, some researchers believe they may live for 80 years or more.

Many visitors combine whale watching with a stay at Kingfisher Bay Resort on nearby Fraser Island K’gari. Packages often include return ferry transfers, accommodation, island tours and whale-watching cruises, making it an excellent way to experience both the island and Hervey Bay’s magnificent Humpback whales.
