What to Expect

As a certified diver, you can enjoy up to three spectacular dives, experiencing three different Great Barrier Reef environments. With the most extensive range of dive sites to visit daily, divers of all levels, from novice to experienced, will be excited by the range of experiences the magnificent sites present, including drift and wall dives, bommie and pinnacle, coral gardens and swim-throughs.


The professional instructors accompany all dives at no extra charge, ensuring maximum safety and enjoyment. In addition, they have intimate local knowledge of the reef systems we visit and are passionate about sharing this! Certified dives last approximately 40 minutes or more, and as a certified diver, you'll need to present proof of certification.


The Great Barrier Reef is an iconic destination and is a diver's dream. The warm waters of the Great Barrier Reef, with temperatures ranging from 22-29 Celsius (75-85 Fahrenheit), makes for comfortable scuba diving all year round. The reef's ecosystem also supports the greatest concentration of life on this planet, including 1,500 species of fish, 400 different kinds of corals, 4000 species of molluscs and 10,000 species of sponges.


In between water activities, relax on the sundecks or in the air-conditioned lounges, and of course, enjoy a delicious hot and cold buffet lunch for hungry adventurers! You'll also indulge in a tasty morning tea upon boarding, including focaccias, muffins/cake selection is served, as well as afternoon tea cakes and cheese and biscuits on the homeward journey. 


Dive Sites


Silversonic visits a selection of over 35 stunning & exclusive World Heritage reef sites at the Agincourt reefs at the very outer edge of the Great Barrier Reef. Here, special reefs known as 'ribbons' run parallel to the Continental Shelf. Adjacent to the Coral Sea trench, these ribbon reefs are recognised as the most pristine ecosystems in the reef's environment. Clear water provides the best possible underwater visibility, encourages rich coral growth and supports spectacular marine life.


Agincourt Reef 1


The Agincourt reefs are a cluster of distinctively separate reefs. Located at the southern end of the reefs chain, Agincourt Reef 1 showcases rich coral diversity and marine life.


Agincourt Reef 2


From the stunning Nursery Bommie, regarded as one of the best dive sites in the region, to wall diving at Izzy's Wall, there are several unique sites Silversonic visits at Agincourt Reef 2.


Agincourt Reef 3


From sandy lagoons littered with coral pinnacles and an old fishing boat wreck at the aptly named "Wreck" site to the thrill of diving and snorkelling along a reef wall with numerous small grottos at The Gap, there's plenty of spectacular marine life and excitement at Agincourt Reef 3.


Agincourt Reef 4


Located at the Northern end of the Agincourt reef chain, Agincourt Reef 4 showcases a rich tapestry of coral and marine diversity. Experience the pretty garden site of The Three Sisters with its three prominent coral bommies to the stunning patch reef with swim-throughs at The Chapel.

Frequently Asked Questions

You will have over 5 hours at the reef sites combined.

All of the reef sites offer great ecological diversity and an abundance of marine life. Some of the commonly seen marine life includes turtles, anemonefish (Nemo), lionfish, cuttlefish, moray eels and reef sharks.

Lycra suits are available on board to reduce the possibility of stings and irritations while also offering protection from the sun.


At certain times of the year (generally November – April), jellyfish, commonly called marine stingers, can affect the seas of Northern Australia. Most jellyfish are harmless to people, however certain varieties may cause a serious reaction. Incidents involving serious marine stings in this area are extremely rare. The crew are conscious of the danger of marine stingers and will take appropriate steps to ensure your protection if they believe conditions are such that there is a possibility of encountering these creatures.

Hopefully not. Silversonic has state-of-the-art ride control systems to ensure a smoother journey. Where there is motion, however, whether in a car, bus, plane or boat, some people will suffer from motion sickness. Motion sickness medication is available onboard for purchase. Ginger tablets are available free onboard as a natural alternative.

Yes, any age is welcome accompanied by an adult, however, The Operator highly recommends that children be confident in the water. Babysitting facilities are not available onboard. The minimum age for scuba diving is 12 yrs.

Depending on the sites visited and conditions of the day, the reef sites offer a range of dive types including drift, wall, bommie, pinnacle, ledge and swim-throughs.

The dives are approximately 12 to 18 metres in depth. The Great Barrier Reef is generally not a deep dive destination, more shallow diving. As coral relies on sunlight for growth, some of the best snorkelling and diving can be done in shallow areas around the reef top.

Yes. The Operator accepts most certification cards including PADI, Naui and SSI. If you forget your card, evidence of certification may be provided by a logbook or verification letter from your certifying dive company. The Operator can provide assistance if you are PADI affiliated.

If you do not have a chance to do a refresher before travelling, you can participate in the first introductory dive of the day and if comfortable then participate in the 2nd and 3rd certified dive.

Certified divers can do up to 3 certified dives during the day. Introductory divers can do 2 dives.

If only one dive is undertaken then a minimum of 12 hours is recommended before flying (to an altitude of 300 metres or greater). If doing multiple dives, an interval of 24 hours is recommended. Other activities to avoid in this period are sky diving, hot air ballooning and going to Kuranda.
