Osprey Reef and Coral Sea liveaboard trips can be booked on their own, as a 4 day / 3 night trip, or in conjunction with a 7 day Ribbon Reefs and Coral Sea expedition. Why so long? Osprey Reef is 230km west of Queensland’s eastern coastline and 350km northeast of Cairns. Day boats can’t get there and liveaboard boats have to cruise a combined total of around 20 hours to get there (these trips are completed while you sleep). The shorter trips include a low-level scenic flight, which get you to or from Cairns to Lizard Island, with a tender transfer to the boat.

Osprey Reef & Coral Sea Dive Sites

The Coral Sea has many dive sites. A feature of most of them is the amazing 1,000m wall drop-offs, clear waters and outstanding pelagic marine life. Most of these liveaboard dive trips focus on Osprey Reef, with its various dive locations such as Admiralty, False Entrance, Around The Bend, North Horn, North Horn Wall, Half Way Wall, Castles, Silver City, Secret Caves, and Rapid Horn. However, pending weather conditions, you may also get to visit Vema, Shark, Bougainville or Holmes Reef which is located South of Osprey reef closer to Cairns.

Maximum dive depths are limited only by Australian safe diving practices / standards, which is 40m for recreational scuba divers. Safe diving is paramount on these trips, due to their remote locations, and dive briefings are thorough and clear.

Visibility is simply amazing and can be up to 100m. The marine life here is different to the Great Barrier Reef: you can expect to see a lot more reef sharks, including Silver-tipped ones and the occasional Hammerhead. There are also large schools of tuna and trevally.

Water temperatures vary from 29 degrees Celsius in Summer to 23 degrees Celsius in Winter: lycra suits and wet suits are provided on the boats. Water entry is generally giant stride, but may also include live drops and tender drop-offs. Nitrox is available on all liveaboard dive boats (should be booked in advance) and some boats allow solo diving (for certified divers) and have rebreathers.

So, other than the sharks and drop offs, what can you expect to see? The dive sites have many interesting features, including swim throughs, caves, ledges, coral bommies, trenches and more. North Horn is home to what we call ‘shark stadium’ and it’s here the Shark Feed dive will be completed, if conditions allow it.

The Shark Feed dive attracts up to 50 reef sharks and was something we always thought would be scary, but is actually just ‘WOW!’. You’ll probably see Black-tipped, White-tipped and Silver-tipped Reef Sharks, Potato Cod, Queensland Groupers, Coral Trout, Red Bass, Trevally, Bumphead Parrotfish, Sweetlips and more.

Osprey Reef & Coral Sea Costs and Inclusions

Cairns liveaboard trips to the Coral Sea & Osprey Reef are generally more expensive than Outer Great Barrier Reef trips. This is due to the distance traveled and the inclusion of a scenic low-level flight, which is an attraction in its own right. These trips also include a brief land excursion and exploration of Lizard Island.

All tours include accommodation, linen, and meals with dive equipment available as an optional extra. The trips visit multiple reef and dive sites.

Non-divers can take these trips (with discounts available) but snorkelling opportunities, due to depth of reef sites, is somewhat limited. However, the boats have spacious sun decks and lounges, so if your non-diver is happy to just relax and enjoy the views, they are more than welcome.

For those wanting to expand their scuba diving skills, you may choose to complete a PADI Advanced or Nitrox Course while on your Cairns liveaboard trip to Osprey Reef & the Coral Sea (certainly a good place for your deep diving module!).
