No gangway will touch land today. At the Lacepede Islands, landing is prohibited, and that is precisely what gives the place its value: this string of low islets set on the Timor Sea, off the Kimberley coast north of Broome, belongs first and foremost to nesting colonies and turtles. Expedition ships approach respectfully, engines idling, before launching the Zodiacs for one of the richest wildlife outings on the entire Australian coast.

A Reserve Observed from the Water

The outing takes place entirely by inflatable boat, through the lagoons and channels that separate the sandbanks. Guides often cut the engine to let the scene speak for itself: the flapping of wings, the dives of the boobies, the discreet breath of a turtle surfacing for air. The landing ban protects the nests in the height of the breeding season, and the boats keep their distance while still offering surprisingly close sightings. The tide, very pronounced in the Kimberley, reshapes the shorelines from hour to hour and determines the route.

The Great Brown Booby Colony

The Lacepedes are home to a brown booby colony considered one of the largest in the world, perhaps the largest. These dark-masked divers cover the sandy ridges by the thousands, take off in squadrons toward schools of fish and return to feed their young in a constant coming and going. Alongside them, Australian pelicans, lesser frigatebirds, masked boobies, eastern reef egrets and several species of terns nest or pass through; up to 20,000 roseate terns have been recorded here. The onboard ornithologists don't know where to point their binoculars, and BirdLife International has designated the archipelago an Important Bird Area.

The Green Turtles of the Channel

Between West Island and Middle Island, the channel concentrates food and attracts green turtles in large numbers. The Lacepedes are the most important breeding site for the species in Western Australia, and it's common to see several around the boats during a single outing: a head breaking the surface, a shell gliding under the hull, a silhouette moving away through the turquoise water. Guides remind everyone of the golden rule: it's the animal that decides the distance, never the other way around.

What to Know Before the Outing

• No landing: the entire excursion is done by Zodiac, usually in small groups accompanied by a naturalist.
• Swell and tide dictate the program; exact times are confirmed the day before by the expedition team.
• A hat, sun protection and covering clothing are essential under this tropical sun, even on a short outing.
• Binoculars and a good telephoto lens transform the experience; the nesting birds won't pose twice for a photo.
• The boats remain stable and accessible; guides help everyone get settled when boarding.

The Kimberley as a Backdrop

This stop is almost always part of an expedition itinerary between Broome and Darwin, in the heart of one of the least populated coastlines on the planet. The Lacepedes give a sense of its scale: not a single pier, not a single dwelling, only pale sandbanks, fish-rich waters and tens of thousands of wings that asked nothing of anyone. Many passengers cite this morning among the highlights of their trip, ahead of far more famous sites, precisely because it is unlike anything they know.

When the Zodiacs head back to the ship, the islets return to their ordinary activity, indifferent to the visit. That may be the lesson of the place: there are still places where human beings are merely passing spectators, and the Timor Sea jealously guards a few of them.
