Encounter an astonishing aggregation of marine wildlife on an unforgettable oceanic expedition. From December to April, their full-day expeditions visit one of the least explored places on earth and the only place in Australia where you can reliably encounter killer whales (orca), the ocean’s undisputed apex predator. Your expedition may also see pods of long-finned pilot whales, sperm whales, a rare beaked whale or blue whale. You can also admire the acrobatics of large pods of bottlenose, striped and common dolphins and encounter shark species that include great whites, whaler sharks and the beautiful oceanic blue, a species never seen from shore. Enormous oceanic sunfish surface and the remains of giant squid sometimes float on the surface, a predator of the deep reduced to scraps, squabbled over by an astonishing array of pelagic seabirds including albatross, shearwater and petrel species. Naturaliste Charter’s world-renowned full-day Killer Whale Expeditions run from Bremer Bay, a two-hour drive from Albany or a 5.5-hour drive from Perth, Western Australia.
