The Ribbon Reefs are long, thin strips of reef, which form the outer edges of the Great Barrier Reef around 50 km - 100 km off the northern Queensland shore and so are accessed only by Australian liveaboards. Characteristically no wider than 450m, they are part of the Great Barrier Reef Marine Park and are covered in colourful corals that attract a plethora of reef life big and small, with sandy gullies separating them, themselves containing interesting critters.

The Ribbon Reefs are generally quite shallow, coming up to as high as 5 metres below the surface from a sandy bottom that is between 15-20 metres below the surface. Show more

Diving Season

Due to Queensland's tropical climate, any time of the year is a good time to dive the Ribbon Reefs. Water temperatures fluctuate between 22°C in winter and 29°C during summer. Thanks to the absence of human activity in the area, visibility is good year round, with best vis from September to November.

During the wet summer months rainfall is moderate but usually limited to early mornings and later afternoons. The dry winter months see little rain. December to February are the rainiest months although the rainfall is often confined to night time. Surface conditions are most often calm but can become moderately rough during winter, although in and around the reefs there is plenty of shelter from the ocean swell.

In the winter months of June and July, dozens of dwarf minke whales can be seen on their migratory path around the Ribbon Reefs. The famous giant potato cod are present all year round.
