A toddler's drowning in a backyard fish pond has led a coroner to call for building authorities in Victoria to regulate fencing for residential ponds. The boy, aged 23 months, drowned in a fish pond in his grandmother's backyard in November 2022. The pond was not fenced off or enclosed in any way, and the toddler was able to access it while his parents were at work and his grandmother was in the shower. The deputy state coroner, Paresa Antoniadis Spanos, has directed her findings to the Victorian Building Authority (VBA) for consideration of the need to regulate the building and design of fish ponds in the interest of child safety. Four children under the age of four have drowned in residential ponds in Victorian since 2010. The VBA has been contacted for a response to the findings.
