|---|---|
| Peak intensity | 110 km/h (70 mph) (10-min); 975 hPa (mbar) |
The origins of Vivienne-Fanja are unclear as a result of sparseness of data, due to a disruption in satellite imagery coverage. It is estimated that a tropical low formed on January 23 west of Christmas Island in the Australian basin.

Steered by a ridge to the south, it moved generally southwestward and intensified into Tropical Cyclone Annette, named by the Bureau of Meteorology. After executing a loop, Annette crossed 80 E into the south-west Indian Ocean on February 16. Upon crossing into the basin, the storm was renamed Jaminy by the Mauritius Meteorological Service.[12]

Early on 8 March, Jim struck Cape Grenville, Queensland. Jim left minor damage to vegetation and downed some large trees. After crossing the Cape York Peninsula, the system emerged into the Gulf of Carpentaria and later made landfall on 9 March at Port Roper, Northern Territory, which is just south of Numbulwar. Jim dissipated on the following day. A 15 m (49 ft) boat was beach at Alyangula. Inland, wind gusts as high as 100 km/h (62 mph) downed trees in the vicinity of the Roper River.[18]

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.[20][21][22]
