The arrival of summer also heralds the time when backyard pools become a popular retreat from the humidity.

But despite numerous warnings, campaigns and media coverage, more than 50% of backyard pools do not comply with safety standards.

By Australian law, all bodies of water over 300mm deep must be securely fenced to prevent young children gaining unsupervised access.

Drowning is a major cause of death in NSW for children under the age of five and pool owners are frequently reminded that there is no substitute for the responsible adult supervision of children in and around swimming pools.

All wading, inflatable and portable pools must be securely fenced.

These holidays, parents are strongly advised to supervise their children at all times when swimming, even in shallow wading pools and bath tubs.
