A Season of Ocean Giants

Bremer Canyon Killer Whale Expeditions

The Bremer Canyon is one of Western Australia’s most extraordinary marine environments, and every summer it becomes the stage for one of the world’s most reliable killer whale gatherings. Legend Charters, now operating as Naturaliste Charters, is proud to open another season of Bremer Canyon Killer Whale Expeditions — a full-day offshore adventure that brings guests face to face with some of the ocean’s most powerful predators.

The 2025–26 season runs from 10 December to 19 April, giving travellers a long window to experience this globally significant hotspot. Each year hundreds of killer whales (orca) return to the Bremer Canyon system to feed, socialise and display remarkable natural behaviour. Few places on Earth offer such consistent sightings, and even fewer allow visitors to witness the scale and energy of the canyon’s wildlife from the comfort of a purpose-built expedition vessel.

What to Expect on a Killer Whale Expedition

A Bremer Canyon Killer Whale Expedition is an adventurous full-day offshore tour, departing from the sheltered waters of Bremer Bay before heading into the deep, nutrient-rich canyon. Once in the canyon, the ocean comes alive. Guests often see killer whales patrolling the edges of the underwater walls, working cooperatively in hunting groups, or cruising at the surface in calm, relaxed pods.

Across the season, expeditions may also encounter sperm whales, long-finned pilot whales, oceanic dolphins, beaked whales and even the occasional blue whale passing through the system. The birdlife is just as impressive, with albatross, shearwaters, petrels and other pelagic species soaring close to the vessel in search of prey.

Marine commentary throughout the day helps guests understand why this region attracts such a dense concentration of life. The canyon’s steep walls funnel cold, nutrient-rich water upwards, creating a powerful upwelling that feeds everything from krill to apex predators. This natural engine drives the food availability that orca return for year after year.

A Day Immersed in Ocean Wildlife

Every expedition is different, but the rhythm of the day follows the excitement of the wildlife. Guests may watch a pod of orca teaching a juvenile how to hunt, observe dolphins surfing the bow, or witness seabirds gathering above the surface as whales feed just below.

The crew take time to position the vessel respectfully, allowing guests to enjoy long, uninterrupted viewing opportunities. Throughout the day, passengers also enjoy morning tea, lunch and afternoon refreshments on board, making it a comfortable and immersive experience out on the Southern Ocean.
