I agree that AED's should be on all dive vessels, Thailand Aust USA Japan everywhere.
Qld had a new code of practice in March 2010
this is an extract
inregards to AED's
(f)
The person conducting the business or undertaking should ensure that a risk assessment is undertaken to determine if an Automatic External Defibrillator (AED) and trained operator should be available for use on a vessel. Factors to consider in conducting the risk assessment are the ability to use the AED safely, the age of the persons undertaking water activities, access to and response time of emergency services, and available personnel.
This is a link to the whole code for those interested

The reason I feel operators on the GBR should have them is because of the marine life and the
risk of heart failure from stings, bites and barbs.
The biggest number of heart attacks on the GBR happen to snorklers.
They usually are the people who cannot dive because they cannot pass the medical or older people who over exert themselves the first week of their holiday and their body is just not use to so much activity.
From what the code says, in theory only, it is not mandatory to carry an AED.
but, and there's always a but,
it is up to the operator to do a risk assessment on each days events.
Boat one is taking six asian business men all over the age of 50 for a day out snorkling and one DSD on the reef.......yes I would manage the risk by taking the AED and ensure a qualified instructor was onboard.
Boat two is taking six asian IT professionals all aged under 30 for a day out snorkling and one DSD on the reef......would get them to fill out a medical form, so I can judge the risk further.
If there are no existing conditions I would accept the risk should an AED be out on the other boat.
Ideally I would have two if I had two boats.
Off course I would hate to be the operator in the corners hearing trying to explain and justify a risk assessment in the event of an incident.
Thanks for this discussion as I have just been looking at purchasing one for training.
In aust the training models seem to cost round $2000
They are expensive.
