Dive Table Considerations: PADI's recommendation after 'multi-day diving' is a minimum pre-flight surface interval of 18 hours. 

»» Guided Dives

Most of their guests prefer to plan and dive independently with their buddy. Single divers are teamed up with other singles and with their staff. It is not their policy for all dives to be divemaster led. They cater to guests who prefer more supervision with a combination of complimentary orientation dives to enhance skills, a scheduled morning and afternoon guided dive and the opportunity to dive with their staff on an ad hoc basis. This service does not provide constant guided dives or a personal dive guide.

Personal Dive Guides
  •  Daily Dive Guide (4-5 dives per day) - $250/day (+ berth cost for guide) 
  •  Personal Per-Dive Guide (approx 2 dives per day). Available on most expeditions subject to staff availability - $50 per dive.

Note: Please request at the time of booking. 

»» Jellyfish

As in all oceans, including the Great Barrier Reef , there are a variety of jellyfish (also known as 'stingers'). The majority of stings that can be inflicted by jellyfish such as hair jellyfish (Cyanea sp.), blubbers (Catostylus sp.) and bluebottles (Physalia sp.) can be irritable to painful but can be prevented by wearing a "Stinger Suit" (available for purchase onboard).

The box jellyfish (Chironex fleckeri) may be present in North Queensland from November to May/June and are found along the coast and estuaries. These stings can cause fatalities in extreme cases however with the right prevention and medical treatment the risk is minimal. There is a small box jellyfish commonly known as the 'Irukandji jellyfish' (Carukia barnesi) one of a series of species that can give rise to 'Irukandji Syndrome'. Fortunately the stings are rarely life threatening, medical aid must always be sought as soon as possible. Immediate first aid is to wash the area with vinegar and seek medical assistance.
