Understand your flood risk

flood-awareness-mapBrisbane’s subtropical climate means our city experiences severe weather events. Because our city is built on a floodplain this can result in flooding from a variety of sources, particularly during the summer storm season from November through to March. However, it is important to note flooding can occur at any time of the year.

Minimising the impact of flooding is everyone’s responsibility.

Be prepared for flooding

Don't wait until it's too late. Council has a range of free tools and information to help residents understand their property's potential flood risk and how to be prepared.
