Tropical cyclones, which are capable of producing extreme winds that may exceed 200km/hour, flooding rains and tremendous sea conditions, are a serious threat to life, property and the environment in coastal areas of Queensland.  A tropical cyclone can last for a few days or up to a few weeks with research showing that cyclones in the Australian region exhibit more erratic paths than cyclones in other parts of the world.

Redland City has been identified as one of seven local government areas in Queensland with the highest total exposure from cyclonic winds, based on a combination of wind speed hazard and concentrations of exposure according to the State Wide Natural Hazard Risk Assessment, Risk Frontiers (2011).

Since the1974‐75 season, there have only been sixteen tropical cyclones come within 500km of Brisbane, and none have approached as close as 100km in that time.  Climate change is predicted to result in more frequent and stronger cyclones impacting Queensland further to the south.  Therefore, given the impacts of climate change and the increases in severity of storms and frequency of east coast lows experienced over the past few years, the potential exists for cyclones to become more frequent within the South East Queensland region.
