Introductory Diving

Introductory Diving On OceanQuest

Introductory diving is a great way to experience the exhilaration of diving without taking a full PADI Open Water Course. The PADI Discover SCUBA is a non-certification program. During your cruise out to the Great Barrier Reef our experienced SCUBA Instructors will clearly guide you through all the skills involved.

The briefing covers all the procedures that will make your day not only safe but an unforgettable experience. You can pre-book a package of 5 Intro Dives on OceanQuest and subject to availability and trip duration you may be able to add more once on board.

Minimum age for intro-diving is 12 years.

Certified Diving

Certified Diving on OceanQuest

Experience the Great Barrier Reef Diving the best way - on a Liveaboard. Our daily departures and flexible trips make this the easiest way to log some serious bottom time in with more than 1,000 different species of fish and many more creatures. Each full day on the Liveaboard offer you a chance to do up to 5 dives.

From an early morning dive getting to watch the reef 'wake up' through to the exhilaration of splashing after dark and seeing some of the nocturnal critters. We also offer the chance to participate in a Fluoro Dive. New in 2017 - Nitrox fills and Courses available.

Fluoro Diving - Exclusive to Divers Den, Cairns

Fluoro Diving - Exclusive to Divers Den, Cairns

This spectacular dive extravaganza brings the reef to life with a range of amazing colours. Bio Fluorescent Diving is available exclusively to Deep Sea Divers Den on board OceanQuest for only $50 per dive, including specialist torches and mask filters which create amazing fluorescent underwater landscapes. Fluoro Diving offers a truly unique and magical experience on the Great Barrier Reef!

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. Fluorescence occurs when an orbital electron of a molecule, atom or nano-structure relaxes back to its ground state, thereby emitting a photon of light, after being excited to a higher quantum state by some type of energy. In our case, we are "hitting" an organism with higher energy light (relatively) in the near-actinic range, and lower energy light (relatively) in the green, yellow and red portion of the spectrum is being emitted. The actual color emitted is determined by how many quantum states the electron has "decayed" or relaxed back to.

​When energy (UV or violet/blue light in our example) strikes an atom, it knocks an electron up to a higher energy state. When the electron decays back to its normal state (usually instantly, after a few nanoseconds), it emits a photon of light (in the more visible, lower energy part of the spectrum in our example).
