Remote. Pristine. Scientifically significant.
Llewellyn Reef is one of the Southern Great Barrier Reef’s most breathtaking and untouched coral systems. Most importantly to us, it is the stewardship site proudly cared for by the Dive Spear and Sport 1770 team. Located deep within the Capricorn–Bunker Group, this offshore reef offers exceptional coral cover, diverse marine life, and some of the most rewarding diving and snorkelling conditions in the region.
Llewellyn Reef is renowned for its vibrant hard coral gardens, dramatic reef walls, swim-throughs, and sand channels that create the perfect habitat for a wide range of species. Whether you’re diving or snorkelling, expect to encounter:
Green and loggerhead turtles
Manta rays (seasonally)
Reef sharks
Tasselled wobbegongs
Schooling trevally and fusiliers
Healthy populations of herbivorous reef fish
Colourful wrasse, butterflyfish, angelfish and more
The reef’s geography creates naturally protected pockets, making it an excellent site for both confident snorkellers and divers seeking exploration.
Llewellyn Reef is not only a favourite for guests, it’s also the primary reef our team looks after as part of our Site Stewardship with the Great Barrier Reef Marine Park Authority.
This means we:
Conduct regular reef health surveys
Monitor coral bleaching, disease and predation
Track indicator species and marine megafauna sightings
Collect valuable citizen science data for the Reef Authority
Remove ghost gear and other marine debris where safe and appropriate
Report notable changes to support local and national reef management
Our commitment ensures that this reef and the ecosystem it supports thrives for generations.
The Gooreng Gooreng, Gurang, Bailai and Taribelang Bunda peoples are the traditional custodians of the Sea Country around the reefs we visit. Evidence of Great Barrier Reef Sea Country connections dates to more than 60,000 years. When you visit the Southern Great Barrier Reef, consider that you’re travelling through Sea Country that has spiritual importance.
