Flood
Wynnum faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity.
Bushfire
The risk of bushfire in Wynnum is relatively low due to the lack of significant bushland within close proximity to residential areas. However, grassfires can still pose a threat during dry periods.
Heat
Wynnum experiences a moderate risk of heatwaves, particularly during the summer months. Increased temperatures can place stress on vulnerable populations and infrastructure.
Storm
Moderate storm risk — severe thunderstorms with hail and damaging winds
