There were twenty tropical cyclones in the Australian region during the 1983-84 season; nearly three times the number that occurred in the 1982-83 season. Eleven of the cyclones developed in the Western Region (WR) whilst seven had their genesis in the Eastern Region (ER) and two formed in the Northern Region (NR). The first cyclone developed late in October 1983. This was early compared with last season when the first cyclone developed late in January 1983. The last cyclone for the 1983-84 season was in the first week of April. There were five cyclones that made landfall along the Australian coast; three of these had two sea•to•land crossings. Overall. the landfall-ing cyclones caused relatively little structural damage as they passed over sparsely populated areas. However, cyclone Kathy devastated the Sir Edward Bellew Group in the southwest Gulf of Carpentaria and caused moderate to severe damage to the nearby mainland township of Borroloola. Kathy was also responsible for the death of one seaperson.
