Research from James Cook University’s Cyclone Testing Station (CTS) shows that compliant products can fail under real cyclone conditions. For example, water ingress tests reveal that doors rated for cyclonic regions can leak litres of water during pressure surges, risking structural damage, and costly repairs.
And by pushing building systems beyond standard test by simulating winds over 160 km/h, driving rain, and flying debris and the QBCC is taking action. Our joint inspections with CTS have uncovered recurring issues, including:
- over-driven nails in plywood bracing and inconsistent batten spacing
- poorly secured solar panels that can become dangerous projectiles
- small, cost-effective upgrades like reinforced battens, correct screw installation, and secure solar panel mounts can dramatically reduce roof failures for as little as $500
- safe rooms, which are reinforced spaces within homes, are also considered a life-saving innovation.
The path forward:
- Practical upgrades: reinforced battens, correct screw installation, and improved solar panel mounts offer cost-effective resilience.
- Safe room guidelines: developed with CTS and supported by the Queensland Resilience and Risk Reduction Fund, these guidelines provide home owners with life-saving options.
- Resilience ratings: similar to ANCAP safety stars for cars, these ratings could soon influence insurance premiums and property values.
As climate risks grow, resilience is not just about safety, it is an economic advantage. Homes built to withstand cyclones will attract better insurance terms and long-term savings. The QBCC is doubling down on our commitment to help ensure construction methods result in safer homes for Queenslanders.
