Frequency and intensity of storms

According to CSIRO modelling the number of tropical cyclone days will increase in the north-east but decrease in the north-west, and the strongest cyclones will become more intense. In addition, the number of days with large hail is likely to increase along the east coast but decrease on the south coast of Australia. CSIRO expects that by 2050, Australia’s coastal towns and cities will face heightened risks from sea-level rise and more frequent severe storms and flooding. This is likely to create substantial risks for infrastructure and primary industries such as fishing and coastal aquaculture. Impacts to fishing may arise through damage to fish habitat and a reduction in the number of fishing days (reduced for the safety of crew, boats and gear). Aquaculture is likely to be affected by increased run-off of rainfall into bays and estuaries and damage to infrastructure such as ponds.
