​​​​​​​​​​Guideline review date: 24 September 2025

This guideline is provided to support schools in implementing the managing risks in school curriculum activities procedure.

The CARA planner (DOCX, 232KB) must be used for the specific school context in conjunction with this guideline considering additional risks, hazards and controls and including environmental, facility, equipment and student considerations.

For activities beyond the scope of this guideline, complete a CARA record using the CARA generic template (DOCX, 98KB).

Activity scope

This guideline demonstrates the minimum safety standard for snorkelling during daylight hours in a swimming pool or open-water environments as an activity to support curriculum delivery. Snorkelling activities may include swimming on the surface of the water using snorkelling equipment, or breath-hold diving and swimming below the surface.

The Department of Education is committed to ensuring that curriculum activities are planned for and managed in accordance with the Work Health and Safety Act 2011 (Qld), to ensure, as far as is reasonably practicable, the safety of students, staff and others.

Activities that pose an unacceptable risk to students are not recommended as part of a snorkelling education program. These activities include, but are not limited to, snorkel diving in underwater caves or wrecks, free diving or extended breath holding, activities involving competitive events (e.g. underwater hockey etc.), adventure racing or spear fishing.

Depending on the scope of this activity, other risk assessments may be required when planning. Curriculum activities encompassing more than 1 CARA guideline (e.g. power boating while swimming in locations other than pools) must comply with the requirements of all CARA guidelines appropriate to the activity.

For activities conducted at a non-Department of Education venue, and/or when engaging external expertise (e.g. charter company), request written risk assessment advice detailing safety management systems (PDF, 630KB), vessel registration, safety and communications equipment and crew qualifications and attach it to this CARA record.

For activities conducted off-site, schools must comply with the school excursions procedure.

Risk level

High risk
Snorkelling undertaken in a municipal, commercial or school swimming pool.
Extreme risk
Snorkelling undertaken in locations outside a swimming pool.

Activity requirements

If any requirement cannot be met, the activity must not occur.

A registered teacher must be appointed to maintain overall responsibility for the activity.

Teachers, in collaboration with the qualified snorkelling supervisor and other adult supervisors of the planned activity, determine additional risks, hazards and control measures relevant to the activity and the specific school/group circumstances in order to lift the safety standard above the minimum identified in the CARA guideline.

Consult review comments from previous CARA records to improve safety standards based on the advice from the previous supervisors of the activity at the school.

Prior consultation and collaboration with local expertise (e.g. lifeguard service, marine park managers) for local advice, emergency support mechanisms and additional supervision requirements to ensure participant and public safety.

Queensland Government zoning and designated areas must be consulted for restricted areas.

Permission/permits are required to be obtained from land managers (e.g. Department of the Environment, Tourism, Science and Innovation, marine park managers, local councils or private landholders), if applicable.

A qualified snorkelling supervisor is to be appointed to plan and coordinate the activity to comply with the current recreational diving, recreational technical diving and snorkelling—code of practice 2024 (PDF, 606KB), including, but not limited to:

  • dive site risk assessment
  • control measures suitable for the location, activity and participants
  • counts of participants
  • process to assess participants to determine whether additional control measures are required for safe participation.
  • process to ascertain supervisor competence (training, qualifications, experience)
  • snorkelling briefings
  • supervision plans
  • emergency and rescue plans
  • equipment safety
  • first aid and oxygen, including for marine stings
  • vessel safety.

Participants must adhere to all rules and advice communicated by the snorkelling supervisor in conjunction with the local lifeguard service, facility operator/owner and any safety signage at the facility/location.

Participants must not snorkel alone.

Implement procedures for regular head counts before, during and after activity and roll marking mechanisms for students leaving the activity.

Supervision

Principals, in consultation with the qualified snorkelling supervisor of the activity, determine the final number of supervisors to fulfil instructional, emergency and supervision roles for the local context that considers the recreational diving, recreational technical diving and snorkelling—code of practice 2024 (PDF, 606KB), the nature of the activity, students' ages, abilities and specialised learning, access and/or health needs. In some instances, the final supervision ratio may be 1:1.

Appropriate adult supervision must be provided to manage the activity safely (i.e. prevent an incident from occurring and manage an incident if one were to occur, including managing emergency situations). At no time should students be relied upon to recover a person in difficulty. The principal must give active consideration to the minimum standards set in the CARA guideline for the activity, the CARA planner and the risk assessment when determining the appropriate level of supervision.

See number of adult supervisors below.

Prepare a supervision plan to prevent drowning that considers the advice provided in this CARA guideline. Consider recreational diving, recreational technical diving and snorkelling—code of practice 2024 (PDF, 606KB), for support when supervision planning.

Where a lifeguard service is available, schools are to collaborate with the lifeguard on the contents of the CARA record prior to the activity for advice and to address any queries they may have. Note: The presence of a lifeguard service does not absolve the school of any supervision requirements unless secured for the sole purpose of the activity.

Participants must adhere to all rules and advice communicated by the local lifeguard service, facility operator/owner and any safety signage at the facility/location.

Before the activity, all adult supervisors:

  • must be familiar with the contents of the CARA record, including the emergency and supervision plans
  • must assess weather conditions, and obtain accurate information on tides, depths, currents and other expected water conditions (if applicable) prior to undertaking the activity, inspecting the intended location in order to identify variable risks, hazards and potential dangers.

During the activity, all adult supervisors:

  • must provide active and direct supervision—be constantly vigilant, attentive and rescue ready
  • must comply with control measures from the CARA record and adapt as hazards arise
  • must not rely on students to recover a person in difficulty at any time.

The activity must be suspended if the conditions become unfavourable (e.g. poor visibility, extreme temperatures, thunderstorms).

Number of adult supervisors

To support decisions about the number of qualified adults required for the activity, confirmation of student water safety and swimming ability is required prior to participation.

See frequently asked questions (FAQs) for further support.

The process is determined by the school and must consider the specific aquatic environments in which the activity will take place. Consult the sequence of competency water safety and swimming education program for support in determining age-appropriate suitability and consider student self-rescue skills in the specific aquatic environment.

At least 2 adult supervisors, including a registered teacher to assume overall responsibility for the activity, must be appointed to supervise the activity. Consult the recreational diving, recreational technical diving and snorkelling—code of practice 2024 (PDF, 606KB) for regulations regarding snorkelling guides and lookouts and supervision requirements.

All adult supervisors must be able to identify, and respond to, risks or hazards that may emerge during the activity including the ability to:

  • recover a student from the water
  • operate signalling devices needed in a duress situation, including marine radio and flares.

Specific roles for supervisors are determined by the qualified snorkelling supervisor to ensure compliance with the recreational diving, recreational technical diving and snorkelling—code of practice 2024 (PDF, 606KB).

See FAQs for further support.

Supervisor qualifications

Qualifications support the minimum safety standard for this activity. Principals make final decisions* in determining supervisor capability (competence, relevance and currency) and whether the activity leader meets an appropriate teaching standard.

*See FAQs for further support.

All adult supervisors must comply with the working with children authority—blue cards procedure.

Qualified adults for the activity

Recovery/emergency—CPR, first aid, rescue

At least 1 adult supervisor is required to have current knowledge, judgement, technique and physical ability to carry out safe water rescues and enact an emergency procedure.

Supervisors must have CPR and first aid qualifications relevant to the activity. Emergency qualifications may include:

  • qualifications in physical education teaching or similar and demonstrated capability and competence (knowledge and skills) in conducting snorkelling activities
  • SISOSNK002—lead snorkelling activities.

Extreme risk activities

In addition to the above, a snorkelling supervisor with:

See FAQs for further support.

Facilities and equipment

The qualified snorkelling supervisor, in consultation with the principal, determines the requirements for facilities and equipment appropriate to the local context and in compliance with the recreational diving, recreational technical diving and snorkelling—code of practice 2024 (PDF, 606KB).

Snorkelling area of an appropriate depth, considering student age and ability, must be clearly defined. Consult the water safety and swimming education program for guidance at each year/band level. Navigational markers must be appropriate for use in the context of the activity and local laws or regulations (e.g. flags, rope floats, anchored buoys linked with ropes).

Consider the use of binoculars and polarised sunglasses to improve visibility across and into the water for adult supervisors who are designated lookouts.

Snorkelling equipment (e.g. snorkels, fins, masks), that is correctly fitted and complies with the requirements of recreational diving, recreational technical diving and snorkelling—code of practice 2024 (PDF, 606KB).

Equipment must conform to Australian Standards specifications, be properly maintained, hygienic, in good working condition, fit for purpose, correctly fitted and used as intended in accordance with the manufacturer's instructions (e.g. face masks with nose pockets and tempered glass, small-bore diameter snorkels for young students with snorkel length less than 30cm).

Equipment must be sized to match the ability and strength of students.

Weight belts must not be used.

A retirement schedule must be developed to replace plant and equipment by manufacturers' nominated expiry date or when significant wear causes a hazard.

Ensure adequate drinking water, food and shade is available for the duration of the activity.

Access to waterways for emergency vehicles and vessels must be available.

In addition to the above, for extreme risk level:

  • first aid kit, oxygen and defibrillator is readily accessible, maintained and used by trained users (e.g. HLTAID015—provide advanced resuscitation and oxygen therapy) in compliance with the code of practice
  • ensure a pontoon, boat or float is in close proximity to students
  • ensure flotation devices (e.g. water noodles) are available for participants and are in close proximity
  • no single navigation system to be relied upon. Where an electronic system (e.g. GPS) is used, have spare batteries and another position-fixing method available (e.g. chart and compass)
  • ensure availability of a knife, dive tool or shears if there is a chance of entanglement.

Common hazards and controls

Further to those listed, include any additional hazards and control measures considering the local context of the activity.

Environmental hazards Control measures

Biological hazards

Glow sticks attached to the top of each snorkel.

A waterproof torch for each participant.

Increase the supervision ratio.

More frequent check-ins

Water temperature Manage cooler water temperatures with additional control measures (e.g. shorter in-water time, wetsuits, etc.). Note: sudden temperature changes may trigger seizures
Facilities and equipment hazards Control measures
Activity location

Location must be suitable for the activity being undertaken to ensure safe participation and that safety rules and procedures can be followed. Undertake a reconnaissance of new or infrequently used locations to ascertain suitability.

Consider depth of water, tidal flow, currents, visibility, underwater vegetation (e.g. coral), marine life (e.g. stonefish, blue-ring octopus, crocodiles, sharks, eels), and debris. Obtain advice from lifeguards, local authority or other relevant authority (e.g. marine park managers) about waterway conditions (e.g. contaminants such as blue-green algae) and other potential hazards (e.g. rips, tides, currents, submerged rocks, water temperature, depth conditions).

Snorkelling area of an appropriate depth, considering student age and ability, must be clearly defined. Consult the water safety and swimming education program for guidance at each year/band level. Navigational markers must be appropriate for use in the context of the activity and local laws or regulations (e.g. flags, rope floats, anchored buoys linked with ropes)

Vessels

For extreme risk level, continually assess threat of other vessels

Manual handling
Lifting equipment, manipulating/moving students

Use correct manual handling processes when lifting, lowering, pushing, pulling or carrying

Student considerations Control measures

Deep water
Risk of drowning, submersion

Allocate safe swimming areas (e.g. shallow water, next to the pool or water's edge) for non-confident or reluctant snorkellers.

Consult the water safety and swimming education program for guidance at each year/band level to:

  • provide learning experiences appropriate to swimming confidence, age and competence
  • ensure depth of water is appropriate to swimming competence and age.

Ensure students with medical conditions participate in an easy access area (e.g. outside lane) in case an emergency procedure is required.

Closely monitor students in deep water.

Restrict access if turbulence may be expected (e.g. where a waterfall empties into deep water)

Entanglement

Wear swimming caps if hair poses a hazard.

Remove accessories (e.g. jewellery, lanyards) before participating

Hyperventilation

Encourage participants to take a full/deep breath before submerging. Closely monitor students for involuntary multiple, shallow breaths.

Do not allow competitive breath-holding or 'no-breath' underwater games. Consult the FAQs for further information

Injury

Students aware of the location of emergency and first-aid equipment

Physical exertion
Exhaustion and fatigue

Continually monitor students for signs of distress (e.g. fear, fatigue, exhaustion, illness, hunger, dehydration, hypothermia, difficulty breathing and hyperventilation).

Adopt and rehearse a system of signals to clearly communicate the need for assistance if in difficulty.

Restrict underwater swimming to short-duration activities under close supervision.

Ensure drink breaks occur regularly. Make water available for individual participants between drink breaks

Student issues
Student numbers, special needs, high risk behaviours, medical conditions, separation from the group

Provide initial snorkelling instruction in shallow water.

Students must not enter the water until instructed to do so by the adult supervisor.

Participants to work far enough apart that they are not struck by another snorkeller kicking.

Participants must snorkel with a paired buddy.

Develop a procedure for students who may develop sea sickness.

Instruct participants to call or signal for assistance if a problem cannot be rectified immediately

Swimming attire
Visibility

Participants must wear personal protective equipment as relevant for the location and conditions (e.g. sunscreen, high visibility stinger suit, enclosed footwear with thick soles when snorkelling where dangers such as stonefish may be present). Consider using the same colour fins or masks, or attaching coloured ribbons/high-visibility wrist bands for medically at-risk students (e.g. asthma, anaphylaxis, epilepsy) if appropriate.

Have students wear easily identifiable clothing (e.g. high visibility rash vest).

Ensure staff can easily recognise those students with health support needs (in and out of the water) and are familiar with their needs
