Charter a luxury vessel to the remote, uninhabited Lacepede Islands — Australia's most significant green turtle nesting site — and slip into gin-clear water alongside whale sharks, manta rays, and vast turtle aggregations in a marine wilderness almost nobody reaches.
What to expect
Departing before dawn, your luxury catamaran threads through the pearl-shell shallows of the Lacepede archipelago as the sun rises over the Indian Ocean. A marine biologist on board briefs you on turtle nesting ecology and whale shark behaviour before you don masks and fins. In the water, green sea turtles glide past at arm's length, and if the season is right, a whale shark — the ocean's largest fish — passes beneath in surreal slow motion. Lunch is a fresh seafood spread served on deck as you drift in protected anchorage.
Good to know
The Lacepedes are accessible by boat from Broome or Derby; transfer logistics depend on your port of call. Seasonal: whale sharks peak March–July; turtle aggregations October–March. Numbers limited to 8 guests. EPBC Act restrictions mean landing on the islands is not permitted — all wildlife encounters are from the water. Pre-book months in advance.
