Cause of death
drowning due to uncontrolled release of water from ruptured rubber dam
AI-generated summary
Four-year-old Nelani Koefer drowned when a rubber dam on the Bedford weir catastrophically failed, releasing an uncontrolled wall of water. The dam had been defectively manufactured with hairline cracks in the inner membrane from 1997, which progressively failed despite repeated patching repairs until final rupture in November 2008. The coroner found that maintenance addressed only symptoms (exterior tears) rather than the root cause (interior defects from manufacturing). Regular visual inspections of the dam, adequate warning signage downstream, and replacement with steel flap gates could have prevented this death. The dam operator had begun exploring alternatives but did not implement changes before the incident occurred.

Contributing factors
- manufacturing defect in rubber dam: hairline cracks in inner membrane from excessively tight radius during fin attachment
- inadequate maintenance approach: external patching did not address root cause of internal defects
- inadequate regular visual inspection of rubber dam
- inadequate warning signage downstream of weir
- public recreational use in dangerous area below dam wall
- delay in implementing replacement of defective dam with steel gates
Coroner's recommendations
- Sunwater remove and not reinstate the rubber fabridams manufactured by Queensland Rubber/Trelleborg at Bedford and Dumbleton weirs
- Sunwater investigate and implement if appropriate steel gates of appropriate design for use on Bedford weir
- Sunwater engage with the Crown and if appropriate the Local Government Association of Queensland to establish an Agreement to allow placement of warning signs in appropriate areas downstream of weirs and dams
- Sunwater install and maintain appropriate signage to warn people of risks in conducting activities in areas below dam and weir walls, with signage placed where readily seen by public and including pictograms for understanding by children and non-English speakers
