About this spot
Cod Hole sits in the Great Barrier Reef World Heritage Area off Queensland, Australia. It's one of Australia's most recognizable dive destinations, known for encounters with massive potato cod (giant grouper) that have been fed by divers for decades. The site attracts visitors from around the world seeking a close-up wildlife experience. The reef environment here remains healthy, with no reported coral bleaching stress, making it a stable destination for reef exploration. The dive itself centers on a small reef formation where the grouper congregate. Divers typically descend to interact with these fish, which are accustomed to human presence and food offerings. The experience is more about wildlife interaction than technical diving challenge, drawing a mix of skill levels. Access is controlled through the Great Barrier Reef permit system. You must dive with licensed operators who manage group sizes and maintain the site's ecological balance. Community observations document at least 12 marine species here, and several dive videos show what to expect. The year-round climate means you can plan a trip almost any month, though seasonal weather patterns do affect sea conditions.
