Extend your bottom time on the Great Barrier Reef with the PADI Enriched Air Diver course in Cairns. This knowledge-focused specialty teaches you to safely dive with nitrox blends, ideal for the repetitive day-trip and liveaboard diving on outer reefs like Flynn, Milln and Thetford. You can certify in a single day, often without any required training dives, and immediately enjoy longer no-decompression limits on multi-dive reef trips.
The PADI Enriched Air Diver specialty is largely theory-based and can be completed without training dives, though Cairns operators often pair it with reef dives. It certifies you to dive nitrox blends up to 40 percent oxygen within recreational limits.
Nitrox really pays off on Cairns reef trips, where day boats and liveaboards run multiple dives a day at outer sites such as Flynn, Milln and Thetford Reefs, and longer no-decompression limits let you spend more time with reef sharks, turtles and Maori wrasse.
