Expedition Cruises on the outer Great Barrier Reef

Covering an area of over 2,600 kilometres and encompassing over 900 islands, the Great Barrier Reef is the world’s largest living structure. Home to an abundant and thriving array of marine and birdlife species, it holds pride of place as one of the seven natural wonders of the world and is listed as a UNESCO World Heritage area.

Onboard these voyages, you will explore rainforest shores, uninhabited sand cays, remote islands and pristine reef systems.  Along the way find freedom and sanctuary amidst this iconic seascape. Our expert guides will share their knowledge with you above and below the water, bringing you close to the natural wonders and wildlife, and giving you a deep understanding of this precious destination.

We pioneered extended expedition cruises on the outer reaches of the Great Barrier Reef 35 years ago and have forged a reputation for excellence in that time as a member of Ecotourism Australia and an accredited and award-winning ecotourism operator.  The Great Barrier Reef is in our DNA and we ensure the most immersive and educational experience possible. Our purpose-designed small ships are built for expedition cruising, with refined steering capabilities, shallow draught and nimble Xplorer tenders. Onboard, enjoy fresh seasonal cuisine and boutique Australian wines and brews. With an intimate atmosphere and our renowned warm Australian hospitality, you will quickly feel at home.

What Are The Ribbon Reefs

Around 50 to 100 km’s off the northern Queensland shore, and forming the outer edges of the Great Barrier Reef. Stretching over 100 miles to the north of Cairns, the “Ribbons” are a string of 10 magical coral reefs. They are no wider than 450m, and generally quite shallow, coming up to as high as 5 metres below the surface from a sandy bottom. A veritable marine wonderland, these long thin strips of reef hold beautiful coral gardens and isolated bommies topped with corals and anemones, surrounded by a rainbow of reef fish. Snorkellers and divers on the Ribbon Reefs might encounter huge giant clams, moray eels, reef sharks and giant Napoleon Wrasse. You might also meet Pelagic fish and see gorgonian fans. If you prefer not to get your feet wet, our glass bottom boat still allows you to get up close and personal to these beautiful species.
