深度ガイドライン
Depth guidelines are based on the divers experience and industry standards. The first dive of each day should not exceed any previous historical maximum depth by more than 3 meters (10ft). Further depth increases are discouraged until the novice diver has had several days experience at that depth. The maximum recommended depth for divers with appropriate experience is 40 meters (132ft). Dives in excess of 40 meters (132ft) can only be undertaken by divers who have experience at same depth to a maximum of 50 meters (165ft).

器材
Air and Nitrox cylinder valves are compatible with US yoke regulators ( UK A clamp) not the European DIN regulators. All divers require an alternative air source, safety sausage and whistle. A dive light plus back up light or chemical light sticks are required for night dives.

ガイド付きダイビング
Most of our guests prefer to plan and dive independently with their buddy. Single divers are teamed up with other singles and with our staff. It is not our policy for all dives to be dive master led. We 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 our staff on an ad hoc basis. This service does not provide constant guided dives or a personal dive guide.

パーソナルダイブガイド	- Daily Dive Guide (4-5 dives per day).
	- Per-Dive Guide (approx 2 dives per day). Available on most expeditions subject to staff availability.

Note: Please request at the time of booking!

クラゲ（スティンガー）
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."

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 also a box jellyfish commonly known as 'Irukandji jellyfish' (Carukia barnesi) one of a series of species that can give rise to 'Irukandji Syndrome'. Fortunately the stings are rarely life threatening, but medical aid must always be sought as soon as possible. Immediate first aid is to wash the area with vinegar and seek medical assistance.
