From the ship's deck, the island seems to be made of nothing but sand. That is almost true. Moreton, set at the entrance to Brisbane's bay, ranks among the largest sand islands in the world, and almost all of its territory is protected as a national park. No paved roads, no town: dunes as high as hills, low forests, beaches stretching as far as the eye can see, and a handful of buildings grouped around the former whaling station of Tangalooma.

Ships anchor off the west coast, in sheltered waters, and passengers reach the shore by tender. From the very first steps, the setting imposes its calm: here, the day revolves around the water, the silence and the light.

The Tangalooma Wrecks

A few hundred metres from shore, a row of rusted hulls emerges from the clear water. Fifteen ships were scuttled there between 1963 and 1984 by the Queensland government, not as the result of a shipwreck, but to create a sheltered anchorage for pleasure boaters. Time has turned this makeshift breakwater into a living reef: coral colonizes the steel plates, more than a hundred species of fish swim among them, and it is not unusual to encounter a turtle, a wobbegong shark or even a passing dugong. Guided snorkelling outings of about an hour and a half leave right from the beach with equipment provided. It is the highlight of the stop, accessible even to average swimmers, as the water stays so calm.

The Dunes of the Inland Desert

Behind the beach, the dunes rise fast and high. 4x4 excursions head into the island's interior, where the silica forms an almost desert-like landscape. Sand tobogganing is the activity here: lying on a waxed board, you hurtle down surprisingly steep slopes in a cloud of silica. The laughter can be heard from afar. Between runs, the panorama from the crest reveals the true extent of the island, fringed with blue on every horizon.

The Beach, Simply

Those who prefer a gentler day need no program. In front of Tangalooma, the beach slopes gently into clear water, pelicans patrol the shoreline, and the facilities of the former whaling station, converted into a resort, offer restaurants and refreshments. From June to November, humpback whales travel along the coast during their migration, and a blow sometimes appears offshore without anyone asking for it. At the northeastern tip, too far for a few hours ashore, stands the oldest lighthouse in Queensland: these shores have guided navigators toward Brisbane for more than a century and a half. The station hunted humpback whales from 1952 to 1962; the region now lives from watching them in season, a turnaround that sums up the times well.

What to Plan For

This port of call is a nature day: a swimsuit, towel, hat, sunscreen and shoes that can handle the terrain will be more useful than a city map. Structured activities — snorkelling at the wrecks, 4x4 tours, sand sliding — are ideally booked in advance through the ship or local operators, as spots go quickly. No private vehicle circulates without a special permit on the island, and that is just as it should be.

At the end of the day, the tender takes passengers back on board as the sun sets over the bay. What remains is sand in your pockets, the image of rusted hulls teeming with fish, and that particular feeling of having spent a few hours on an island that has built almost nothing, and didn't need to.
