The majority of children under five years of age who drown in swimming pools, do so as a result of fencing that is not compliant with legislation.

The most effective home pool safety measure is proper adult supervision at all times. Portable and inflatable pools capable of being filled to at least a depth of 300mm are required by law to be surrounded by a swimming pool safety barrier.
Ensure the pool gate is always closed and never propped or left open. Learn infant and child resuscitation and display a CPR chart near the pool or spa. Keep pot plants and other furniture away from the swimming pool fence so that they can not be used to climb over to gain access to the pool.
