Arc along Australia’s vast west coast on an extended journey from tropical Darwin to Perth, the far-flung outpost on the Indian Ocean. You’ll explore rarely visited archipelagos — the lively tides of the Buccaneer group and Dampier’s 42 idyllic isles — and, while sailing, keep an eye out for humpbacks, dugongs, and dolphins. Snorkel through dense coral ecosystems and nature sanctuaries before digging into Australia’s Indigenous heritage and its preserved cave art.
