Living with Cyclones: Cairns and the Tropical Season

Tropical cyclones are an unavoidable dimension of life in Cairns and the broader tropical north of Queensland. The cyclone season, running from November through April, brings the combination of monsoon moisture, warm sea surface temperatures, and the atmospheric conditions that generate the intense rotating weather systems whose passage can cause extreme damage to coastal communities. Cairns has been relatively fortunate in the direct hits it has received from major cyclones in recent decades, but the preparedness culture that the risk requires is deeply embedded in how the city manages its built environment and how residents plan their year.

Cyclone preparedness in Cairns is a community-wide enterprise that extends from the preparation of individual properties, including the securing of loose outdoor items and the stocking of emergency supplies, to the maintenance of the built infrastructure in standards that withstand category 4 and 5 winds. The building code requirements for cyclone regions, more stringent than those applied in the south, mandate construction standards that provide significantly better protection than the housing stock of comparable communities in non-cyclone-rated regions.

The evacuation planning that local government and the Queensland Disaster Management Committee maintain for cyclone events provides the community with the information and procedures that organised response requires. The identification of evacuation routes, the establishment of emergency accommodation, and the public communication systems that provide real-time cyclone tracking information have been developed through experience with multiple events and the lessons each has contributed to improved emergency management practice.

The recovery economy that follows a significant cyclone event provides a reminder of how dependent the regional community is on infrastructure that cyclone damage can destroy. Road and bridge reconstruction, power restoration, and the rebuilding of the housing and commercial stock that wind and flooding damage affect are large-scale economic activities that post-cyclone periods generate in ways that are individually devastating but that the regional economy collectively manages.
