What level of physical fitness is required for diving?

Divers should have a reasonable level of physical fitness to cope with the environmental stresses of being underwater, including exertion required for propulsion through water, heat loss, breathing compressed gas, changes in the cardiorespiratory system, changes in gas volume and pressure within air spaces in the body, and introduction of gases that can have various effects on bodily functions.

Can I consume alcohol before diving?

No. Drinking alcohol before and during diving trips endangers not only yourself but your diving buddy. Alcohol reduces reaction time, visual tracking performance, concentrated attention, ability to process information, perception, and execution of psychomotor tasks. Alcohol also causes dehydration which is considered to be one of the prime causes of decompression illness. Do not consume alcohol before diving or water activities.

How long should I wait before flying after diving?

You should not go to altitude (fly) within 12 hours of completing a single dive or a minimum of 18 hours when doing multiple dives (recommended 24 hours).

Q: What medical questionnaire do I need to complete for introductory dives?

For introductory dives, you will need to fill in a Medical Questionnaire. If answering YES to any question it will not necessarily disqualify you from diving, but will indicate the need for a medical assessment by a qualified physician prior to diving that conforms to Australian Medical Standard AS4005-1.

You will be required to complete a safety waiver prior to dive and snorkel activities.

"Snorkelling and diving demand fitness and swimming skills. Harsh conditions amplify the inherent risks of these activities.

You must disclose any/all: allergies, pre-existing medical conditions, medications, recent surgeries or injuries to the crew. It might just save your life. It's also a legal requirement - fines of more than $3,700 apply for falsifying a medical disclosure form. Your safety, first."

Dive Medical Information

When Diving in Australia there are different regulations and requirements compared to those in other countries. The following rules apply in Queensland.

Introductory Dives

You will need to fill in a Medical Questionnaire. If answering YES to any question it will not necessarily disqualify you from diving, but will indicate the need for a medical assessment by a qualified physician prior to diving that conforms to Australian Medical Standard AS4005-1.

Experienced / Certified Divers

Prior to diving, you may be asked to fill out a Medical Questionnaire; this is not a legal requirement but is done in your own best interests.

The purpose of the questionnaire is to determine whether you should be examined by a doctor. There may be a pre-existing condition that has not stopped you from diving in your own country, but Australian laws do not allow; or perhaps there could be a new condition developed since you became qualified to dive which may affect your safety while diving.

If you answer YES to any of the conditions listed on the Medical Questionnaire, we recommend you see a physician for further assessment in order to scuba dive. It is best to visit a physician whilst in Australia, as this medical will comply with Australian Standards (AS4005.1).

Scuba diving is an exciting and demanding activity. To scuba dive safely, you must not be extremely overweight or out of condition. Diving can be strenuous under certain conditions. Your respiratory and circulatory systems must be in good health. All body spaces must be normal and healthy. A person with heart trouble, a current cold or congestion, epilepsy, asthma, a severe medical problem, or is under the influence of alcohol or drugs, should not dive.If taking medication, consult your doctor before taking part in this program.

Dive Medical Questionnaire

The purpose of this Medical Questionnaire is to find out if you should be examined by a physician before participating in recreational diving. A positive response to a question does not necessarily disqualify you from diving. A positive response means there is a pre-existing condition that may affect your safety while diving and you must seek the advice of a physician.

Please answer the following questions on your past and present with a YES or NO. If you are not sure, answer YES. If any of these items apply to you, we must request that you consult with a physician prior to participating in scuba diving. Your instructor will supply you with a PADI Medical Statement and Guidelines for Recreational Scuba Diver’s Physical Examination to take to a physician.

Have you suffered from, or do you now suffer from any of the following:

Asthma or wheezing
Recurrent ear problems when flying
Brain, spinal cord or nervous disorder
Fainting, seizures or blackouts
Epilepsy
Heart disease of any kind
Chronic Bronchitis or persistent chest complaints
Diabetes Mellitus (sugar diabetes)
Collapsed lung (pneumothorax)
Chronic sinus conditions
Tuberculosis or other long-term lung disease
Ear surgery
Chest surgery

Are you currently suffering from:

Breathlessness
High Blood Pressure
Pregnancy
Chronic Ear Discharge or infection
Other illness or operation within the last month
Perforated eardrum
Are you currently taking and medicine or drug (excluding oral contraceptives)?
Have you ingested any alcohol within the last 8 hours prior to diving?
Do you understand that any concealment of any condition incompatible with safe diving might put your health or life at risk?
Do you understand that you should not go to altitude (fly) within 12 hours of completing a single dive or a minimum of 18 hours when doing multiple dives (recommended 24 hours)?

General Fitness

Divers should have a reasonable level of physical fitness to cope with the environmental stresses of being underwater. The environmental factors that place a physiological strain on the diver include:

Exertion required for propulsion through the surrounding water.
Heat loss to water that is generally colder than body temperature.
Breathing gas of compressed density.
Changes in the cardiorespiratory system from using underwater breathing gear.
Changes in the gas volume and pressure within air spaces in the body eg; ears, stomach, etc.
Introduction into the body of gases that can have toxic, narcotic, stimulatory or gas solubility effects on bodily functions.
The human body, in reasonable condition and without injury or illness, can deal with the effects of most of these factors.

Flying After Diving

The pressure of diving causes nitrogen to go into solution in the blood, and it is the decrease in pressure as the diver returns to the surface that causes this nitrogen to come back out of solution over time. A rapid ascent to the surface can cause complications as it represents too fast a transition across a pressure gradient for the body to effectively compensate for.

Ascending to a high altitude after the dive is simply a continuation of your post-dive ascent to the surface and can also lead to decompression sickness. It’s recommended that you should wait at least 12 hours after a single dive, or 24 hours after multiple dives within the no-decompression limits before you travel to more than 300m (or 1,000 feet) above sea level. Bear in mind that driving over a mountain range would also put you over this suggested altitude limit.

Alcohol

Drinking alcohol before and during driving trips endangers not only yourself but your diving buddy. Alcohol reduces the ability of the individual to process information and impairs their ability in terms of:

Reaction time
Visual tracking performance
Concentrated attention
Ability to process information in divided attention tasks.
Perception (Judgement)
The execution of psychomotor tasks.
Alcohol also cause dehydration which is considered to be one of the prime causes of decompression illness. Do not consume alcohol before diving or water activities.
