Medical fitness

The following statement appears on all Mike Ball Dive Expeditions 'Booking Form':

I state that I am in good health for diving. I have no medical history of heart or lung disorders, asthma or epilepsy, neither am I an insulin dependent diabetic. I will not dive on your expedition if I am feeling unwell or I have a chest cold or respiratory congestion on the expedition. I understand if I have any medical condition contrary to these requirements I must produce a diving medical certificate completed by a diving medical specialist.

You are authorized to make medical and transport arrangements as may be determined in my best interest. I agree to pay expenses incurred on my behalf which may be charged against my credit card.

Alcohol

Consumption of alcohol is restricted until after your last dive for the day.

Coral Spawning

Coral spawning normally takes place when the water temperature is approximately 27 degrees and between the 2nd & 6th days after the November full moon. Warmer than median temperatures can cause the date to coincide with an earlier full moon, cooler conditions can cause spawning to coincide with a later full moon.

Disabled Divers

Dive sites may be quite exposed which can create comfort and safety issues for disabled divers. Spoilsport was not designed to facilitate disabled divers and is not suitable for divers who cannot make their own way around the vessel.

Prior to booking, please complete and return the Disabled Dive Questionnaire.

  • Cabins, bathrooms and diving are accessed from the main deck. Entry to the accommodation companionway has a step 23.5cm high and 12cm across. Door width is 61.5cm.
  • Dining and lounge areas are one deck up with 11 steps (21.5cm high & 65cm wide). Entry to the saloon has a step 26cm high and 10cm across. Door width is 61.5cm. 
  • Dive entry is via a platform 170cm above the water or by 8 steps (24cm high and 57.5cm wide).
  • Premium, standard and club cabins have private adjoining bathrooms. Cabin doors are 57cm wide. Step height into bathrooms is 4cm. All showers have a sunken tray of 5cm.
  • The rear Premium cabins have a double and single berth. Standard cabins have twin single beds. The smaller Club and Budget cabins are less convenient with bunk style beds and very small bathrooms. 

Also to be taken into consideration is the Lizard Island transfer in an inflatable dinghy, the walk from the airstrip to the beach (approx 400m with 30 across the beach) and the dimensions of our chartered aircraft which range from 5 to 12 seaters.

Supervision / Dive Buddy - A disabled diver must be completely independent or have an able-bodied buddy who can provide assistance for various conditions in and out of the water. We can provide an additional crew member to provide some assistance at an additional cost (refer Personal Guide Costs). This does not include physically manoeuving guests around the vessel or lifting from water!

Dive Site Selection

Dive site selection is based on the best dive sites available. Less experienced divers receive complimentary "orientation dives" as necessary while experienced divers are given the freedom to plan their own dives.

Depth Guidelines

Depth guidelines are based on the diver’s experience and industry standards. The maximum recommended depth for divers with appropriate experience is 40 metres (132ft). Dives in excess of 40 metres (132ft) to a maximum of 50 metres (165ft) can only be undertaken by divers with a minimum experience of 100 dives with 25 deeper than 30 metres (100ft) including one to a depth within 3 metres of dive being undertaken. 

Equipment

Nautilus Lifeline - All divers are required to use a Nautilus Lifeline GPS. Guests on standby or promotional fares pay small rental fee.

Dive Cylinders - We have 42 tanks onboard 50% Air and 50% Nitrox; two thirds average 10.3 L (80 cuft) and one third average 11.3L (88 cuft);

Cylinder Valves – Air and Nitrox cylinder valves are compatible with US yoke regulators (UK A clamp)

DIN Fitting Regulators – We have 16 cylinder valves with a removable plug which will accommodate European DIN style regulators.

Equipment  - Wetsuits

Please see the weather chart for water temperatures. If you feel the cold we recommend a 3mm full wetsuit in the warmer months (Nov - Feb) and a 5mm  full wetsuit in the cooler months (Mar - Oct). For rental wetsuit sizes please click here.

Flying after Diving

The Mike Ball 'Fly/Dive' flights are at an altitude of 200 to 300 metres. This does not exceed the '600 metre Flying and Diving ceiling' requiring adherence to the 'Flying after Diving' procedures.

Commercial Flight Considerations: The surface interval between your last dive on Mike Ball Dive Expeditions completed at 5pm and flying out of Cairns (at say 11am) is 18 hours. Read below!

Dive Computer Considerations: Normally on completion of diving at the end of your expedition your computer's 'No Fly' times are less than 18 hours. Wait an appropriate amount of time (as indicated by your computer) before flying in excess of 600m.

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

Guided Dives

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 divemaster 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.

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

A variety of jellyfish inhabit the Great Barrier Reef. The majority of jelly fish stings are irritable to painful.

The box jellyfish (Chironex fleckeri) can be present at inshore waters and estuaries in North Queensland from November to May.  Sting can be fatal in extreme cases. Fortunately they are not seen at the outer reefs we frequent.

The small Irukandji box jellyfish (Carukia Barnesi) can be found on the offshore reefs.  Stings are very painful however are rare and rarely life threatening.  Immediate first aid is to wash the area with vinegar and seek medical assistance. Since 1969 we have evacuated 2 guests with 'Irukandji Syndrome', no treatment was required.

Prevention: Full wet suits are recommended or Stinger Suits which are available for purchase onboard (advise size if required). Spoilsport has radio contact with emergency services.

Unlimited Diving

Most divers do 2 morning, 2 afternoon plus a night dive most nights. Normally we have an ‘open deck’ at a single site in the morning and visit 2 sites in the afternoon - this may be reversed.  This provides divers with the freedom to dive as much or as little as they want.
