The South Pacific region is prone to significant tropical cyclone risk. This report was part of the Tropical Cyclone Risk Assessment in the Pacific Region project which compared both current and future tropical cyclone risk under climate change for 14 Pacific Island countries and Timor-Leste. Geoscience Australia evaluated datasets derived from 11 General Circulation Models (GCMs) under two different model frameworks (CMIP 3 and CMIP 5) representing two distinct future climate scenarios.

GA reports on the changes in the tropical cyclone risk from the current climate to the future climate via a number of tables called peril-matrices, which were subsequently used to calculate projected financial losses from cyclone damages to buildings, infrastructure and crops in each country, for mid-century and end of century.

The project supported the third phase of the Pacific Catastrophe Risk Assessment and Financing Initiative (PCRAFI), and was supported by the Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) Programme with co-financing from the Global Fund for Disaster Risk Reduction (GFDRR). The project involved a collaboration between the Australian Government, Geoscience Australia (GA), and AIR Worldwide (AIR).
