The 1984–85 Australian region cyclone season was one of the most active seasons on record. It officially started on 1 November 1984, and officially ended on 30 April 1985.
A Category 3 cyclone, Emma struck Western Australia on December 12, 1984, as a Category 1 cyclone.
Due to its minimal intensity, 04S was designated only as a tropical storm strength cyclone by the Joint Typhoon Warning Center (JTWC). The storm remained unnamed by the warning center in Darwin.
Tropical Cyclone Frank was a significant tropical cyclone which formed off the western coast of Australia. It peaked as a Category 1 storm on the Saffir-Simpson Hurricane Scale according to the JTWC. Perth assessed it as a category 4 on the Australian scale. After it turned to the south-east on 25 December, it made landfall as a Category 2 two days later near Port Hedland, Western Australia.
Monica peaked as a category 2 storm, tracking roughly south-eastward, passing into the South Pacific basin on December 28.
The precursor low to Cyclone Nigel formed as an ill defined low, within the intertropical convergence zone near the Cape York Peninsula during January 1985. Over the next several days the system gradually moved eastwards into the Coral Sea, before the BoM reported that a recognizable circulation had developed during January 14. Over the next two days the low moved eastwards and slowly developed further, before the JTWC initiated advisories on the system and designated it as Tropical Cyclone 13P early on January 16. Later that day the BoM named the system Nigel as it became equivalent to a modern-day category 1 tropical cyclone on the Australian tropical cyclone intensity scale and moved out of the Australian region into the South Pacific basin.
Odette was a powerful cyclone.
Gertie made landfall in Western Australia before dissipating.
