Challenger Bay - Great Barrier Reef
Challenger Bay, tucked between Ribbon Reef #9 and #10, is one of those spots that just delivers. We love the extensive hard coral fields here, a real eye-opener with their colours, not just the usual brown and green. They’re laced with these sandy gullies, and if you hover patiently, you’ll catch the garden eels swaying in the current. The site starts shallow, just 5m, and slopes gently. It’s perfect for a long, relaxed dive, really letting you take in the details. Keep an eye out for stingrays gliding over the sand, and we’ve often seen white tip reef sharks patrolling the outer edges – they’re usually busy hunting. Our pick for an afternoon dive, when the light plays beautifully through the corals and highlights the pink anemonefish in their homes. This is a site for divers who appreciate vibrant coral health and the smaller, subtler marine life, though the sharks are a nice bonus.
