Marble Island, Duke Islands, Queensland

Part of the Duke Island group, Marble Island is a private island located 20km off the coast of central Queensland totaling eight square kilometers. The island lies within the Great Barrier Reef UNESCO World Heritage Sited waters.

Well-traveled “yachties” consider the Duke Group of islands to be one of the most beautiful archipelagos in Queensland.

Those seeking ultimate quiet and R&R will appreciate the seclusion of Marble Island.


Marble Island was settled in the 1800s for agricultural purposes.  At the turn of the century mining started on a part of the island which had a source of iron ore.

The island was developed as a cattle property, and still today cows are managed on the island.

Marble Island is named for the pink and white marble found on the island.

Natural environment

Marble Island’s geography is similar to other continental islands in the area – such as the Whitsunday islands. The island boasts 20 private beaches and bays. The island has hilly terrain and contains a lot of bushland.

Green turtles use the island as a breeding ground. Marble Island is on the migratory path of sperm whales (with their calves) – sightings are possible between August and October.

As well, the island’s managers, Charlie and Gabrielle Winten, set up a table on the top of a bluff for sunset drinks.


Only one group can visit Marble Island at a time.

The island’s facilities are geared towards the cattle business, and include dams, cattle yards, refrigerated rooms, offices, working sheds, the manager’s residence, the owner’s holiday residence, and a “farmstay” beach cottage.

The guest accommodation is a self-contained modern cottage located on a private beach overlooking Home Bay, which can accommodate four adults or two adults and up to four children. The cottage contains a full-sized kitchen, two en-suite bedrooms, and a living room with satellite TV. The main bedroom can contain either a king-sized bed or two single beds. The second bedroom contains two single bunk bed sets (totaling four beds). The cottage boasts a beautiful covered patio with BBQ facilities. The cottage has protective mosquito screens on all windows.

The accommodation includes fresh linen, bath, and beach towels weekly. Guests are welcome to use oyster knives, snorkeling equipment, fishing equipment, the cottage’s beach umbrella, board games, and the John Deer “Gator” – a six-wheel 4WD buggy.

Guests must bring all necessary provisions for their visit, however food and beverage can be pre-ordered through a Rockhampton supplier and added to the charter plane cargo. Even local delicacies such as oysters and mud crabs can be pre-ordered and stored in a cold room prior to the flight.


Camping is possible as part of the cottage rental. Ten additional guests can stay on the island provided they bring their own camping equipment.
