Main article: Cyclone Kathy

Severe Tropical Cyclone Kathy was a powerful tropical cyclone that devastated the Sir Edward Pellew Group of Islands in March 1984. Originating from a tropical low off the southern coast of Papua New Guinea. Tracking westward, the system attained gale-force winds by 18 March before striking the Cape York Peninsula. After crossing the area, Kathy entered the Gulf of Carpentaria where environmental conditions favored significant development. On 22 March, the storm attained its peak intensity as a Category 5 severe tropical cyclone (Australian tropical cyclone intensity scale) with ten-minute sustained winds of 205 km/h (125 mph). By this time, the storm had been tracking towards the southwest and struck the Sir Edward Pellew Group of Islands later on 22 March before moving over the Australian mainland as a slightly weaker system. Once over land, Kathy rapidly degraded, losing gale-force winds within 24 hours; the storm dissipated over the Northern Territory on 24 March.

One person died and damaged totaled to 12 million.[3][4][5]
