In the oversight of aquatic locations, WorkCover Queensland emphasizes the importance of supervision, particularly at public swimming pools. The primary responsibility of a pool lifeguard is to oversee patrons within the aquatic environment, with a critical focus on preventing drownings, which are often silent and lack noticeable movements.

According to the Royal Life Saving Society of Australia’s Guidelines for Safe Pool Operations (GSPO), aquatic facilities, both outdoor and indoor, on non-residential premises must have adequate supervision. This entails having at least one person over 18 years old, possessing a skill set equivalent to that of a pool lifeguard, capable of maintaining effective supervision, and able to respond to a person in distress within 30 seconds.

WorkCover Queensland underscores that duty holders are obligated to provide necessary supervision, aligning with the Work Health and Safety Act 2011. The determination of what is 'reasonably practicable' is an objective test, considering what can be done to ensure health and safety, and what is reasonably able to be done in minimizing risks.

The application of the WHS Act extends to the supervision and general operation of public pools without organized recreational water activities. Duty holders organizing such activities may also fall under the Safety in Recreational Water Activities Act 2011.

WorkCover Queensland provides a Supervision at public swimming pools – Self-assessment tool to minimize safety hazards. The determination of what is 'reasonably practicable' considers the likelihood and potential harm of hazards or risks.

For compliance with the GSPO's minimum supervision requirements, a qualified lifeguard actively supervising patrons is recommended. The consideration of what is 'reasonably practicable' guides the determination of whether additional lifeguards are needed during breaks or other times.

In scenarios where providing GSPO-recommended supervision is not reasonably practicable, duty holders must still manage risks under the WHS Act. Small regional town facilities may face challenges, and a risk assessment guides the introduction of controls, such as employing additional staff or implementing timed sessions.

WorkCover Queensland addresses common scenarios, emphasizing that duty holders are not discharging their duties if distractions hinder a supervisor from performing their role. Signage alone is not acceptable for supervision at public swimming pools without lifeguards. Duty holders must ensure patrons are aware of risks, obtain confirmation, exclude at-risk swimmers, and provide alternate rescue facilities.

The Royal Life Saving Australia Guideline for Aquatic Supervision is a valuable industry standard, serving as guidance for pool operators. Compliance with the guideline, as an example of best practice, may satisfy duties under the WHS Act, considering all circumstances related to what is reasonably practicable.
