A Humpback Whale: The Majestic Journey Begins
Every year as the southern hemisphere cools a humpback whale begins its incredible migration from Antarctica to the warmer waters of Western Australia.
This seasonal movement spans over 10,000 kilometres and is one of the longest migrations of any mammal on Earth. What drives them?
Instinct, survival, and the need to reproduce. As they leave behind the nutrient-rich southern feeding grounds, these whales stop eating and begin to rely entirely on stored fat reserves.
The journey is demanding, yet vital. Along the way, they pass through coastal towns that offer some of the best whale watching on the planet.
Travellers and locals alike gather on boats and shores for the chance to witness these majestic animals in motion. At Naturaliste Charters, we invite you to be part of this awe-inspiring experience.
Seeing a humpback whale breach, fluke, or simply glide through the water is a gift that never fails to leave a lasting impression.
What Makes a Humpback Whale Unique?
A humpback whale is more than just a large marine mammal—it’s a marvel of evolution and intelligence. These whales grow up to 16 metres long and weigh as much as 30,000 kilograms.
They’re recognised by their enormous flippers, which can span nearly a third of their body length. Humpbacks are filter feeders, using baleen plates to strain out krill and small fish.
They display an incredible range of behaviours rarely seen in other species: breaching, lobtailing, and even synchronized swimming. Their heads are covered in unique knobs called tubercles, each housing a hair follicle likely used for detecting motion or vibration in the water.
Each individual also has distinct markings on its tail fluke, allowing researchers to identify and track them over time. Unlike most whales, humpbacks are also acrobats and vocalists.
From physical adaptations to cultural behaviours, there’s no mistaking the charismatic nature of a humpback whale.
Humpbacks in Augusta
Augusta is one of the earliest locations in Western Australia to welcome a humpback whale each migration season. From late May through to August, the protected waters of Flinders Bay become a playground for these mighty animals.
Calm conditions and shallow depths offer humpbacks the perfect stopover during their northbound journey. It’s common to witness males competing for female attention through displays of power and agility—chasing, breaching, and slapping fins against the surface.
Sometimes, a mother and calf can be seen gliding close to shore. These sightings are not only thrilling but also provide scientists with valuable data.
The season also attracts southern right whales, offering the potential to witness both species in one trip. At Naturaliste Charters, we navigate these waters daily, guided by experienced crew and marine experts.
Our tours in Augusta create the ideal opportunity to experience a humpback whale in its most dynamic and expressive form.
Why They Breach
Breaching is one of the most awe-inspiring behaviours you can witness in a humpback whale. This massive animal propels itself fully out of the water, twists in the air, and lands with a thunderous splash.
But why do they do it? While it’s impossible to know exactly what motivates a whale, researchers believe breaching serves several possible functions.
It could be a form of communication—sending sound waves across long distances through the water. It may also be a method of dislodging parasites or dead skin.
Some scientists even believe it’s a display of strength, used by males to impress potential mates or intimidate rivals. And let’s not forget the possibility that whales breach for fun.
Whatever the reason, seeing a humpback whale breach up close is unforgettable. On our charters, guests often witness multiple breaches in a single tour.
Each one is different, but they all have the power to take your breath away.
Dunsborough’s Whale Season
From late August through November, Dunsborough transforms into a haven for a humpback whale returning south. By this point, many females have given birth and are now nursing calves.
The sheltered waters of Geographe Bay offer calm seas and safety from predators, making it the perfect nursery. Guests aboard Naturaliste Charters often spot mother-calf pairs swimming side by side.
Mothers are fiercely protective and often seen guiding, feeding, and teaching their young. The calves, still learning to navigate, sometimes breach or roll at the surface in clumsy but endearing fashion.
These moments are a powerful reminder of the life cycle playing out beneath the waves. Dunsborough’s picturesque setting adds to the magic—sparkling bays, pristine beaches, and crystal-clear views.
Our tours provide not only close whale encounters but also insights into their behaviour. Seeing a humpback whale in Dunsborough feels like stepping into a living marine documentary.
The Power of the Humpback’s Song
One of the most mysterious traits of a humpback whale is its song. Only the males sing, and they do so in long, structured patterns that can last for up to 30 minutes.
These songs are not random—they’re composed of distinct themes and phrases, often repeated in perfect rhythm. Scientists believe the songs are used to attract mates, but they may also play a role in social bonding or navigation.
Interestingly, all males in a given population sing the same song, and it evolves over time. This makes humpbacks one of the few non-human species to demonstrate cultural learning.
Using hydrophones on our tours, we let guests listen to the haunting melodies in real time. Hearing a humpback whale sing is an emotional experience—one that connects you deeply with life beneath the surface.
It’s one more reason these animals continue to inspire awe and curiosity around the world.
