North Wall at Osprey Reef is a remote, deep-water site characterised by a vertical drop-off starting at 5 metres and extending to 40 metres. This exposed location is subject to strong, variable open ocean currents, making it suitable only for advanced divers capable of managing drift conditions. Visibility is excellent, typically ranging between 30 and 60 metres. Due to the site's remote nature and potential for down currents, divers must be self-sufficient. A reef hook is recommended to maintain position along the wall. The site is accessible only by boat and offers opportunities for night diving.

Time your dive around slack water if possible, but expect the current to pick up quickly; a reef hook is worth carrying so you can hold position at depth and watch the action rather than fighting to stay in place.
Access is exclusively by multi-day liveaboard dive boats departing from Cairns. The journey to the remote atoll takes approximately 24 hours.
