Bremer Canyon 2025 – Killer Whale Expeditions That Delivered

Bremer Canyon 2025 – Killer Whale Expeditions That Delivered

After months out on the water with Naturaliste Charters, we can confidently say 2025 has been a remarkable orca season. From mid December to March, Bremer Canyon gave us breathtaking sightings, thrilling hunts, and unforgettable wildlife moments. We witnessed powerful behaviours and delicate family bonds across a variety of orca pods. Each day offered something different, keeping us on our toes and connected to the wild.

Guests onboard experienced intimate encounters with orcas cruising beside the boat, or hunting just beyond the bow. Every trip gave us something to talk about. The range of wildlife, combined with ever-changing ocean conditions, made every expedition unique. The Bremer Canyon proved again why it’s one of Australia’s most incredible marine environments.


New Life on Display – Calves Steal the Show

One of the biggest season highlights was the birth of several new orca calves during the early part of the season. We met Wren, the bright and playful calf seen beside her mother Akama, who charmed everyone with her antics. Wren often rolled through the swell and launched into tiny spy-hops, drawing smiles from all onboard.

Just days later, we were introduced to Susu, a brand-new calf travelling with Banksey in Hermes’ pod. Susu’s orange hue and tiny stature made her easy to spot among the adults. Watching these young orcas interact, learn, and explore gave us a rare glimpse into early orca life. They stayed close to their mothers but confidently surfed waves and explored the surface.

These calves were clear signs of a healthy population, and their energy brought a sense of hope to every tour.


Incredible Orca Behaviour – From Hunts to Play

Throughout the season, we saw the full spectrum of orca behaviour—from gentle surfacings to coordinated and brutal hunting displays. One day, we witnessed a high-speed surge, followed by an oil slick and blood in the water. It was likely a beaked whale taken down by a skilled pod working together with precision.

Moments like these were intense but important. They reminded us that orcas are apex predators, evolved for efficiency and teamwork. We also enjoyed quieter moments, watching families rest, play, and socialise. We often saw spy-hopping, belly rolls, and tail slaps as pods passed by peacefully.

Chopper, the dorsal-finless orca, became a regular this season. Despite his missing fin, he moved confidently and playfully. He has become a favourite among returning guests. Males like Blackberry, Clayton, and Scotty also made rare appearances, adding another layer of excitement to already incredible days.


Marine Diversity and Rare Bird Sightings

This season wasn’t just about orcas. We cruised alongside pilot whales and saw bronze whaler sharks circling under the surface. Sunfish glided by on still days, and common dolphins often rode the bow, thrilling passengers with their speed and grace. A long-nosed fur seal surprised us by hauling out at Glasse Island—an unexpected and rare sighting.

The birdlife was spectacular, and at times, surprising. Wandering albatross followed the vessel for hours with wingspans over three metres. Shy albatross, Indian yellow-nosed albatross, and flesh-footed shearwaters were constant companions out at sea.

This year, we were lucky to spot some rare birds too, including white-chinned petrels and a single grey-headed albatross. These sightings thrilled bird enthusiasts onboard. The diversity and abundance of marine and bird life reminded us of how alive this ocean truly is.


Reflections on an Unforgettable Season

Now that the Bremer Canyon season is wrapping up, we’re reflecting on just how special this year has been. These killer whale expeditions gave us a deeper understanding of orca behaviour, family dynamics, and the ecosystem they thrive in.

We saw orcas teaching calves, socialising, and feeding. We witnessed rarely-seen males travelling between pods. Every guest left with unforgettable memories, a deeper appreciation for the ocean, and countless stories to tell.

The arrival of new calves like Wren and Susu was a standout season highlight, showing that this population is growing and healthy. We feel incredibly lucky to have shared these moments with so many passionate people.

Apex Predator & Orca Behaviours

Exploring the dynamic marine environment of Bremer Bay offers unparalleled opportunities to witness the intricate behaviours and interactions of its apex predators, particularly the orcas.

Apex Predator Interactions

In March 2024, an extraordinary event unfolded in the Bremer Canyon when a pod of orcas encountered a sperm whale. This rare interaction provided a unique glimpse into the complex dynamics between these formidable species. The encounter was marked by the sperm whale employing a defensive tactic, releasing a cloud of faeces—a behaviour believed to deter predators. Such events underscore the raw and unpredictable nature of marine life in the Bremer Canyon, offering a vivid reminder of the ongoing battle for survival in the ocean’s depths.

Seasonal Highlights

The Bremer Bay orca season, particularly in February 2024, was marked by a series of remarkable sightings and interactions. Expeditions during this period reported not only frequent orca encounters but also sightings of other marine species, including pilot whales and various seabirds. These observations highlight the rich biodiversity of the region and the dynamic nature of its marine ecosystem. Each tour offered unique experiences, reflecting the ever-changing patterns of wildlife activity in the Bremer Canyon.

Expedition Experiences

Embarking on a killer whale expedition from Bremer Bay is more than just a tour; it’s an immersive journey into the heart of a thriving marine ecosystem. Guests can expect to traverse the stunning landscapes of the Southern Ocean aboard the ‘Alison Maree,’ a 23-meter catamaran designed to handle the local oceanic conditions. The vessel offers three spacious viewing decks and an air-conditioned interior, ensuring comfort throughout the voyage. During the expedition, participants may witness a variety of marine life, from orcas and pilot whales to seabirds like albatrosses and shearwaters. The crew, comprising experienced marine biologists and naturalists, provides insightful commentary, enriching the experience with knowledge about the behaviours and ecology of the observed species. Each day on the water is unique, with the potential for unexpected and thrilling wildlife encounters that leave lasting impressions.

The Power of Predation

In the vast expanse of the Bremer Canyon, the circle of life is vividly on display, showcasing both the raw power of predation and the tender moments of new beginnings.

During an expedition in January 2025, guests aboard the Alison Maree witnessed a significant oil slick upon approaching the hotspot. This slick, a telltale sign of a recent orca predation event, indicated the aftermath of a successful hunt. Such observations provide a rare glimpse into the orcas’ role as apex predators, highlighting their hunting prowess and the dynamic nature of the marine ecosystem in Bremer Bay.

A New Life in the Canyon

In contrast to these powerful displays, the canyon also offers moments of profound tenderness. On January 29, 2025, the crew observed a newborn orca calf accompanying Fanscar’s pod. The calf, with its fresh foetal folds and a floppy dorsal fin, was estimated to be less than a day old. Akama, a member of the pod, was identified as the likely mother, staying in close proximity to her newborn.

This sighting underscores the importance of the Bremer Canyon as a nurturing ground for orca families, offering hope for the continued growth and vitality of the population.
